A circular status of a countdown timmer [duplicate]

I am trying to create a rounded progressbar. This is what I want to achieve
There is a grey color background ring. On top of it, a blue color progressbar appears which moves in a circular path from 0 to 360 in 60 or whatever amount of seconds.
Here is my example code.
<ProgressBar
android:id="#+id/ProgressBar"
android:layout_width="match_parent"
android:layout_height="match_parent"
style="?android:attr/progressBarStyleLarge"
android:indeterminateDrawable="#drawable/progressBarBG"
android:progress="50"
/>
To do this, in the drawable "progressBarBG", I am creating a layerlist and inside that layer list I am giving two items as shown.
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#android:id/background">
<shape
android:shape="ring"
android:innerRadius="64dp"
android:thickness="8dp"
android:useLevel="false">
<solid android:color="#color/grey" />
</shape>
</item>
<item android:id="#android:id/progress">
<clip>
<shape
android:shape="ring"
android:innerRadius="64dp"
android:thickness="8dp"
android:useLevel="false">
<solid android:color="#color/blue" />
</shape>
</clip>
</item>
Now, the first grey ring is generated fine. The blue ring however starts from the left of the drawable and goes to the right just like how a linear progressbar works. This is how it shows at 50% progress with the red color arrow showing direction.
I want to move the blue progressbar in circular path as expected.

Here are my two solutions.
Short answer:
Instead of creating a layer-list, I separated it into two files. One for ProgressBar and one for its background.
This is the ProgressDrawable file (#drawable folder): circular_progress_bar.xml
<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:fromDegrees="270"
android:toDegrees="270">
<shape
android:innerRadiusRatio="2.5"
android:shape="ring"
android:thickness="1dp"
android:useLevel="true"><!-- this line fixes the issue for lollipop api 21 -->
<gradient
android:angle="0"
android:endColor="#007DD6"
android:startColor="#007DD6"
android:type="sweep"
android:useLevel="false" />
</shape>
</rotate>
And this is for its background(#drawable folder): circle_shape.xml
<?xml version="1.0" encoding="utf-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="ring"
android:innerRadiusRatio="2.5"
android:thickness="1dp"
android:useLevel="false">
<solid android:color="#CCC" />
</shape>
And at the end, inside the layout that you're working:
<ProgressBar
android:id="#+id/progressBar"
android:layout_width="200dp"
android:layout_height="200dp"
android:indeterminate="false"
android:progressDrawable="#drawable/circular_progress_bar"
android:background="#drawable/circle_shape"
style="?android:attr/progressBarStyleHorizontal"
android:max="100"
android:progress="65" />
Here's the result:
Long Answer:
Use a custom view which inherits the android.view.View
Here is the full project on github

With the Material Components Library you can use the CircularProgressIndicator:
Something like:
<com.google.android.material.progressindicator.CircularProgressIndicator
app:indicatorColor="#color/...."
app:trackColor="#color/...."
app:indicatorSize="64dp"/>
You can use these attributes:
indicatorSize: defines the radius of the circular progress indicator
trackColor: the color used for the progress track. If not defined, it will be set to the indicatorColor and apply the android:disabledAlpha from the theme.
indicatorColor: the single color used for the indicator in determinate/indeterminate mode. By default it uses theme primary color
Use progressIndicator.setProgressCompat((int) value, true); to update the value in the indicator.
Note: it requires at least the version 1.3.0-alpha04.

I have done with easy way:

txtProgress.setText(pStatus + " %");
}
});
try {
Thread.sleep(100);

}
pStatus++;
}

Hope this will help you.

I have written detailed example on circular progress bar in android here on my blog demonuts.com. You can also fond full source code and explanation there.
Here's how I made circular progressbar with percentage inside circle in pure code without any library.
first create a drawable file called circular.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#android:id/secondaryProgress">
<shape
android:innerRadiusRatio="6"
android:shape="ring"
android:thicknessRatio="20.0"
android:useLevel="true">
<gradient
android:centerColor="#999999"
android:endColor="#999999"
android:startColor="#999999"
android:type="sweep" />
</shape>
</item>
<item android:id="#android:id/progress">
<rotate
android:fromDegrees="270"
android:pivotX="50%"
android:pivotY="50%"
android:toDegrees="270">
<shape
android:innerRadiusRatio="6"
android:shape="ring"
android:thicknessRatio="20.0"
android:useLevel="true">
<rotate
android:fromDegrees="0"
android:pivotX="50%"
android:pivotY="50%"
android:toDegrees="360" />
<gradient
android:centerColor="#00FF00"
android:endColor="#00FF00"
android:startColor="#00FF00"
android:type="sweep" />
</shape>
</rotate>
</item>
</layer-list>
Now in your activity_main.xml add following:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/dialog"
tools:context="com.example.parsaniahardik.progressanimation.MainActivity">
<ProgressBar
android:id="#+id/circularProgressbar"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="250dp"
android:layout_height="250dp"
android:indeterminate="false"
android:max="100"
android:progress="50"
android:layout_centerInParent="true"
android:progressDrawable="#drawable/circular"
android:secondaryProgress="100"
/>
<ImageView
android:layout_width="90dp"
android:layout_height="90dp"
android:background="#drawable/whitecircle"
android:layout_centerInParent="true"/>
<TextView
android:id="#+id/tv"
android:layout_width="250dp"
android:layout_height="250dp"
android:gravity="center"
android:text="25%"
android:layout_centerInParent="true"
android:textColor="#color/colorPrimaryDark"
android:textSize="20sp" />
</RelativeLayout>
In activity_main.xml I have used one circular image with white background to show white background around percentage. Here is the image:
You can change color of this image to set custom color around percentage text.
Now finally add following code to MainActivity.java :
import android.content.res.Resources;
import android.graphics.drawable.Drawable;
import android.os.Handler;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.animation.DecelerateInterpolator;
import android.widget.ProgressBar;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
int pStatus = 0;
private Handler handler = new Handler();
TextView tv;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Resources res = getResources();
Drawable drawable = res.getDrawable(R.drawable.circular);
final ProgressBar mProgress = (ProgressBar) findViewById(R.id.circularProgressbar);
mProgress.setProgress(0); // Main Progress
mProgress.setSecondaryProgress(100); // Secondary Progress
mProgress.setMax(100); // Maximum Progress
mProgress.setProgressDrawable(drawable);
/* ObjectAnimator animation = ObjectAnimator.ofInt(mProgress, "progress", 0, 100);
animation.setDuration(50000);
animation.setInterpolator(new DecelerateInterpolator());
animation.start();*/
tv = (TextView) findViewById(R.id.tv);
new Thread(new Runnable() {
#Override
public void run() {
// TODO Auto-generated method stub
while (pStatus < 100) {
pStatus += 1;
handler.post(new Runnable() {
#Override
public void run() {
// TODO Auto-generated method stub
mProgress.setProgress(pStatus);
tv.setText(pStatus + "%");
}
});
try {
// Sleep for 200 milliseconds.
// Just to display the progress slowly
Thread.sleep(8); //thread will take approx 1.5 seconds to finish
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}).start();
}
}
If you want to make horizontal progressbar, follow this link, it has many valuable examples with source code:
http://www.skholingua.com/android-basic/user-interface/form-widgets/progressbar

I realized a Open Source library on GitHub CircularProgressBar that does exactly what you want the simplest way possible:
USAGE
To make a circular ProgressBar add CircularProgressBar in your layout XML and add CircularProgressBar library in your projector or you can also grab it via Gradle:
compile 'com.mikhaellopez:circularprogressbar:1.0.0'
XML
<com.mikhaellopez.circularprogressbar.CircularProgressBar
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:background_progressbar_color="#FFCDD2"
app:background_progressbar_width="5dp"
app:progressbar_color="#F44336"
app:progressbar_width="10dp" />
You must use the following properties in your XML to change your CircularProgressBar.
Properties:
app:progress (integer) >> default 0
app:progressbar_color (color) >> default BLACK
app:background_progressbar_color (color) >> default GRAY
app:progressbar_width (dimension) >> default 7dp
app:background_progressbar_width (dimension) >> default 3dp
JAVA
CircularProgressBar circularProgressBar = (CircularProgressBar)findViewById(R.id.yourCircularProgressbar);
circularProgressBar.setColor(ContextCompat.getColor(this, R.color.progressBarColor));
circularProgressBar.setBackgroundColor(ContextCompat.getColor(this, R.color.backgroundProgressBarColor));
circularProgressBar.setProgressBarWidth(getResources().getDimension(R.dimen.progressBarWidth));
circularProgressBar.setBackgroundProgressBarWidth(getResources().getDimension(R.dimen.backgroundProgressBarWidth));
int animationDuration = 2500; // 2500ms = 2,5s
circularProgressBar.setProgressWithAnimation(65, animationDuration); // Default duration = 1500ms
Fork or Download this library here >> https://github.com/lopspower/CircularProgressBar

Here is a simple customview for display circle progress. You can modify and optimize more to suitable for your project.
class CircleProgressBar #JvmOverloads constructor(
context: Context, attrs: AttributeSet? = null, defStyleAttr: Int = 0
) : View(context, attrs, defStyleAttr) {
private val backgroundWidth = 10f
private val progressWidth = 20f
private val backgroundPaint = Paint().apply {
color = Color.LTGRAY
style = Paint.Style.STROKE
strokeWidth = backgroundWidth
isAntiAlias = true
}
private val progressPaint = Paint().apply {
color = Color.RED
style = Paint.Style.STROKE
strokeWidth = progressWidth
isAntiAlias = true
}
var progress: Float = 0f
set(value) {
field = value
invalidate()
}
private val oval = RectF()
private var centerX: Float = 0f
private var centerY: Float = 0f
private var radius: Float = 0f
override fun onSizeChanged(w: Int, h: Int, oldw: Int, oldh: Int) {
centerX = w.toFloat() / 2
centerY = h.toFloat() / 2
radius = w.toFloat() / 2 - progressWidth
oval.set(centerX - radius,
centerY - radius,
centerX + radius,
centerY + radius)
super.onSizeChanged(w, h, oldw, oldh)
}
override fun onDraw(canvas: Canvas?) {
super.onDraw(canvas)
canvas?.drawCircle(centerX, centerY, radius, backgroundPaint)
canvas?.drawArc(oval, 270f, 360f * progress, false, progressPaint)
}
}
Example using
xml
<com.example.androidcircleprogressbar.CircleProgressBar
android:id="#+id/circle_progress"
android:layout_width="200dp"
android:layout_height="200dp" />
kotlin
class MainActivity : AppCompatActivity() {
val TOTAL_TIME = 10 * 1000L
override fun onCreate(savedInstanceState: Bundle?) {
...
timeOutRemoveTimer.start()
}
private var timeOutRemoveTimer = object : CountDownTimer(TOTAL_TIME, 10) {
override fun onFinish() {
circle_progress.progress = 1f
}
override fun onTick(millisUntilFinished: Long) {
circle_progress.progress = (TOTAL_TIME - millisUntilFinished).toFloat() / TOTAL_TIME
}
}
}
Result

I'm new so I can't comment but thought to share the lazy fix. I use Pedram's original approach as well, and just ran into the same Lollipop issue. But alanv over in another post had a one line fix. Its some kind of bug or oversight in API21. Literally just add android:useLevel="true" to your circle progress xml. Pedram's new approach is still the proper fix, but I just thought I share the lazy fix as well.

try this method to create a bitmap and set it to image view.
private void circularImageBar(ImageView iv2, int i) {
Bitmap b = Bitmap.createBitmap(300, 300,Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(b);
Paint paint = new Paint();
paint.setColor(Color.parseColor("#c4c4c4"));
paint.setStrokeWidth(10);
paint.setStyle(Paint.Style.STROKE);
canvas.drawCircle(150, 150, 140, paint);
paint.setColor(Color.parseColor("#FFDB4C"));
paint.setStrokeWidth(10);
paint.setStyle(Paint.Style.FILL);
final RectF oval = new RectF();
paint.setStyle(Paint.Style.STROKE);
oval.set(10,10,290,290);
canvas.drawArc(oval, 270, ((i*360)/100), false, paint);
paint.setStrokeWidth(0);
paint.setTextAlign(Align.CENTER);
paint.setColor(Color.parseColor("#8E8E93"));
paint.setTextSize(140);
canvas.drawText(""+i, 150, 150+(paint.getTextSize()/3), paint);
iv2.setImageBitmap(b);
}

#Pedram, your old solution works actually fine in lollipop too (and better than new one since it's usable everywhere, including in remote views) just change your circular_progress_bar.xml code to this:
<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:fromDegrees="270"
android:toDegrees="270">
<shape
android:innerRadiusRatio="2.5"
android:shape="ring"
android:thickness="1dp"
android:useLevel="true"> <!-- Just add this line -->
<gradient
android:angle="0"
android:endColor="#007DD6"
android:startColor="#007DD6"
android:type="sweep"
android:useLevel="false" />
</shape>
</rotate>

https://github.com/passsy/android-HoloCircularProgressBar is one example of a library that does this. As Tenfour04 stated, it will have to be somewhat custom, in that this is not supported directly out of the box. If this library doesn't behave as you wish, you can fork it and modify the details to make it work to your liking. If you implement something that others can then reuse, you could even submit a pull request to get that merged back in!

Change
android:useLevel="false"
to
android:useLevel="true"
for second sahpe with id="#android:id/progress
hope it works

Good news is that now material design library supports determinate circular progress bars too:
<com.google.android.material.progressindicator.CircularProgressIndicator
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
For more info about this refer here.

if you want to set progress in an anti-clock direction then use below image for set fromDegree and toDegree's values in progressDrawble xml.
<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:fromDegrees="270"
android:toDegrees="-90">
<shape
android:innerRadiusRatio="2"
android:shape="ring"
android:thickness="1dp">
<gradient
android:angle="0"
android:endColor="#007DD6"
android:startColor="#007DD6"
android:type="sweep" />
</shape>
</rotate>
This code will let your progress anti-clockwise and from the top.
Change the degrees as per the above image from where you want to rotate your progress bar.

You can use this library https://github.com/xYinKio/ArcCircleProgressBar
This is one of the most flexible circular progress bars

How to make selected one button in a list of button?

I have more than one button in a LinearLayout and they all have different click option. I want to make when I choose one of them it will selected and change its background then I select the other one first ones selected gone and new one turn selected and background will change. I have 8-9 button or more. How can I do that?
This is action_main.xml
<HorizontalScrollView
android:id="#+id/horScrollView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scrollbars="horizontal">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:padding="5dp">
<ImageButton
android:id="#+id/spaceship"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:srcCompat="#drawable/spaceship" />
<ImageButton
android:id="#+id/mask"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="10dp"
app:srcCompat="#drawable/mask" />
</LinearLayout>
</HorizontalScrollView>
This is Main.java
ImageButton spaces = findViewById(R.id.spaceship);
spaces.setBackgroundColor(Color.TRANSPARENT);
spaces.setOnClickListener(view -> {
if(getChecked())
spaces.setBackgroundColor(Color.TRANSPARENT);
else
spaces.setBackgroundColor(Color.DKGRAY);
setChecked(!check);
modelLoader.loadModel(this, R.raw.sample_ship);
setRenderable(spaceShipRendeble);
});
ImageButton mask = findViewById(R.id.mask);
mask.setBackgroundColor(Color.TRANSPARENT);
mask.setOnClickListener(view -> {
if(getChecked())
mask.setBackgroundColor(Color.TRANSPARENT);
else
mask.setBackgroundColor(Color.DKGRAY);
setChecked(!check);
modelLoader.loadModel(this,R.raw.mask);
setRenderable(maskrendeble);
});
Firstly, I set check variable "false".
For example, one button selected, and it turn gray, than I choose another button turns gray and first selected will turn transparent. But I can't do it.

#OnClick({R.id.next,R.id.country_us,R.id.country_india})
public void nextClicked(View view)
{ switch(view.getId()) {
case R.id.next:
Intent intent = new Intent(this, TutorialScreen.class);
intent.putExtra("country_selected", ind_sel);
startActivity(intent);
break;
case R.id.country_india:
ind_sel=true;
setselectedBlank();
view.setBackgroundResource(R.drawable.selected_border);
break;
case R.id.country_us:
ind_sel=false;
setselectedBlank();
view.setBackgroundResource(R.drawable.selected_border);
break;
}
}
private void setselectedBlank() {
country_us.setBackgroundResource(R.drawable.border);
country_india.setBackgroundResource(R.drawable.border);
}
you could try this just call a method to change background of all to default first then change it to selected colour after that
please note i a using ButterKnife injection library here but even if you are not using it its not an issue
Happy Coding
ImageButton spaces = findViewById(R.id.spaceship);
spaces.setBackgroundColor(Color.TRANSPARENT);
spaces.setOnClickListener(view -> {
setAllnotSelected();
spaces.setBackgroundColor(Color.DKGRAY);
});
ImageButton mask = findViewById(R.id.mask);
mask.setBackgroundColor(Color.TRANSPARENT);
mask.setOnClickListener(view -> {
setAllnotSelected();
mask.setBackgroundColor(Color.DKGRAY);
});
public void setAllnotSelected();
{
mask.setBackgroundColor(Color.TRANSPARENT);
spaces.setBackgroundColor(Color.TRANSPARENT);
}

You can check for one ImageButton for the condition whether it is checked. Base on that you can make all other setChecked() false.I have use the same for setting values of RadioButtons.
if (Friends != null) {
Friends.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (isChecked) {
friend_source = "Friend";
Newspaper.setChecked(false);
Facebook.setChecked(false);
Zomato.setChecked(false);
RadioSource.setChecked(false);
}
}
});
}

Create a resourse file that has different colours for the different states of teh button.
btn_bg_states.xml:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true">
<shape>
<solid android:color="your_color" />
</shape>
</item>
<item android:state_pressed="true">
<shape>
<solid android:color="your_other_color" />
</shape>
</item>
<item>
<shape>
<solid android:color="your_default_color" />
</shape>
</item>
</selector>
then set it as a background drawable to all buttons, and Android will handle the rest for you.
android:background="#drawable/btn_bg_states"

Selected item not work in listview

I have listview (android.support.v7.widget.RecyclerView ) in my HomeLayout.
Code in HomeLayout
<LinearLayout
p1:orientation="horizontal"
p1:minWidth="25px"
p1:clickable="true"
p1:minHeight="25px"
p1:layout_width="wrap_content"
p1:layout_height="45dp"

p1:clickable="true"
p1:scrollbars="horizontal"
p1:state_activated="true"
p1:layout_width="match_parent"
p1:layout_height="45dp" />
</LinearLayout>
List view have custom adapter. Adapter code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:p1="http://schemas.android.com/apk/res/android"
p1:orientation="horizontal"
p1:focusable="true"

</LinearLayout>
Textview have custom design for press p1:background="#drawable/designforselected" Code for designforselected is
<?xml version="1.0" encoding="UTF-8" ?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

</item>
<item>

<corners
android:topLeftRadius="5dp" android:topRightRadius="5dp" android:bottomLeftRadius="0dp"
android:bottomRightRadius="0dp" >
</corners>
</shape>
</item>
</selector>
State_pressed is work but state_selected no work. Why ? Ty
I wish the solution to XML file

You need to implement the listView onClick like this:
listContent.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
String item = ...;
Toast.makeText(getBaseContext(), item, Toast.LENGTH_LONG).show();
}
});

I had similar issue not long ago with state_selected. Try state_checked or state_activated instead.

In your adapter write this:
#Override
public void onBindViewHolder(ViewHolder viewHolder, final int i) {
final GridItem nature = mItems.get(i);
viewHolder.tvspecies.setText(nature.getName());
viewHolder.imgThumbnail.setImageResource(nature.getThumbnail());
viewHolder.imgThumbnail.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Log.i("CLick",nature.toString());
}
});
}
This is a way that works to me. Of course you need use your ids

How to change the background of a android Dialog Box

How can I change the background color programatically of a dialog box?
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setCancelable(false);
builder.setMessage(R.string.tnc)
//.setTitle(R.string.tnc_title)
.setPositiveButton(android.R.string.ok, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
Log.d(TAG, "OK Button Clicked");
dialog.dismiss();
finish();
}//end onClick
});
AlertDialog dialog = builder.create();
dialog.show();

This is the best way to do it !
Firstly make a dialog box programmatically .
public void onClick(View v) {
dialog1 = new Dialog(Page.this,R.style.myBackgroundStyle);
Window window = dialog1.getWindow();
window.setGravity(Gravity.CENTER);
window.setLayout(WindowManager.LayoutParams.FILL_PARENT,
WindowManager.LayoutParams.FILL_PARENT);
window.setBackgroundDrawable(new ColorDrawable());
dialog1.setTitle(null);
dialog1.requestWindowFeature(Window.FEATURE_NO_TITLE);
window.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
dialog1.setContentView(R.layout.custom_dialog);
dialog1.getWindow().setBackgroundDrawable(
new ColorDrawable(android.graphics.Color.TRANSPARENT));
dialog1.setCanceledOnTouchOutside(true);
description.setText(DESCRIPTION);
heading_name.setText(PRODUCT_NAME);
Button abc = (Button)dialog1.findViewById(R.id.abc);
abc.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});
Button xyz = (Button) dialog1.findViewById(R.id.xyz);
retailer_btn.setOnClickListener(new View.OnClickListener() {
dialog1.dismiss();
}
});
dialog1.show();
}
});
and now create a new xml file and set this code in your xml (Dialog Layout)
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/description_layout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginTop="45dp"
android:layout_gravity="top|right"
android:gravity="right|top"
android:orientation="vertical" >
<LinearLayout
android:id="#+id/desription_layout2"
android:layout_width="160dp"
android:layout_height="90dp"
android:layout_marginRight="2dp"
android:padding="2dp"
android:background="#drawable/dropdown_white_background"
android:orientation="vertical" >
<Button
android:id="#+id/abc"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_weight="2"
android:background="#drawable/curve_1"
android:text="abc"
android:textSize="18dp"
android:textColor="#000000"/>
<View
android:layout_width="fill_parent"
android:layout_height="2dp"
android:layout_marginBottom="1dp"
android:layout_marginTop="1dp"
android:background="#ffffff" />
<Button
android:id="#+id/xyz"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_weight="2"
android:background="#drawable/curve_1"
android:text="xyz"
android:textSize="18dp"
android:textColor="#000000"/>
</LinearLayout>
</LinearLayout>
and if you want to do additional stuff with your dialog such as rounding the corners of the dialog of the button then create a new xml in the drawable and the add this as the background accordingly.
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true">
<shape android:shape="rectangle">
<corners android:radius="3dip" />
<stroke android:width="1dip" android:color="#ffffff" />
<gradient android:angle="-90" android:endColor="#ccffff" android:startColor="#ccffff" />
</shape>
</item>
<item android:state_focused="true"><shape android:shape="rectangle">
<corners android:radius="3dip" />
<stroke android:width="1dip" android:color="#ffffff" />
<solid android:color="#66ffff" />
</shape>
</item>
<item>
<shape android:shape="rectangle">
<corners android:radius="3dip" />
<stroke android:width="1dip" android:color="#66ffff" />
<gradient android:angle="-90" android:endColor="#66ffff" android:startColor="#66ffff" />
</shape>
</item>
</selector>
Hope this helps :)

In that case you require to make a custom dialog box.
Refer this tutorial here which illustrates that well.
http://www.codeproject.com/Tips/659766/Android-Custom-DialogBox
Hop it helps.!!

Create a custom layout and set it as the layout for your dialog box.
You can use this code:
final Dialog dialog = new Dialog(getActivity());
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.custom_dialog_box);

How to make progress bar fill slowly

I have a progressbar in drawable. I want it to fill slowly whenset progress is done. That is it I should be able to see it filling, not in a flash. Also I have a texview inside that progressbar, I want that textview to keep revolving and as soon as the set progress filling completes, the textview should stop revolving and display progress.
Here is my code:
Layout:
<ProgressBar
android:id="#+id/circularProgressBar"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="150dip"
android:layout_height="150dip"
android:layout_centerInParent="true"
android:indeterminate="false"
android:max="100"
android:progress="0"
android:progressDrawable="#drawable/progressbar" />
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:textSize="47sp"
android:textStyle="bold"
android:textColor="#color/Theme" />
</RelativeLayout>
progressbar.xml
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:id="#android:id/background">
<shape
android:innerRadiusRatio="3"
android:shape="ring"
android:thicknessRatio="7.0"
android:useLevel="false" >
<solid android:color="#color/Red" />
</shape>
</item>
<item android:id="#android:id/progress">
<shape
android:innerRadiusRatio="3"
android:shape="ring"
android:thicknessRatio="7.0" >
<solid android:color="#color/Theme" />
</shape>
</item>
</layer-list>
Also, I have a textview inside this progressbar, I want it to keep rotating until the progress is done. How to do that, I have an animation for that but it is not working.
Here is the code:
rotate.xml
<rotate xmlns:android="http://schemas.android.com/apk/res/android" >
android:duration="4000"
android:fromdegrees="0"
android:pivotx="50%"
android:pivoty="50%"
android:todegrees="360"
android:toyscale="0.0"
</rotate>
It gives warnings like this: Unexpected text found in layout file: "android:fromdegrees="0" android:pivotx="50%"
android:pivoty="50%" android:todegrees="360" android:to..."

Use this code it will help you.

Create a Property for the progress:
final Property<ProgressBar, Integer> progressProperty = new Property<ProgressBar, Integer>(
int.class, "progress") {
#Override
public Integer get(ProgressBar object) {
return object.getProgress();
}
#Override
public void set(ProgressBar object, Integer value) {
object.setProgress(value);
}
};
Create and start an ObjectAnimator for that property on your ProgressBar (mProgressBar):
private void animateProgressBar(int targetProgress) {
ObjectAnimator anim = ObjectAnimator.ofInt(mProgressBar, progressProperty, targetProgress);
anim.setInterpolator(new DecelerateInterpolator());
anim.setDuration(300);
anim.start();
}
You can costumize the animation with Interpolators, different duration, ecc
You can also use:
private void animateProgressBar(int targetProgress) {
ObjectAnimator anim = ObjectAnimator.ofInt(mProgressBar, "progress", targetProgress);
anim.setInterpolator(new DecelerateInterpolator());
anim.setDuration(300);
anim.start();
}
without declarying the Property, but I don't like this approach that much.

I don't know about the text rotation, but for slowly increasing the progress bar, you can try this one:
mProgressBar is a global progress bar variable which is holding the instance of your progress bar
mProgress is a global integer variable initially set to 0, to monitor the current level of your progress bar.
pSize is the amount you want to increase the progress bar from the current level.
pSleepTime is the speed you want the progress bar to fill up. I usually use 50.
private void setProgressBar(int pSize, int pSleepTime) throws InterruptedException {
for(int i=0;i<pSize && mProgress<100;i++){
mProgress++;
Thread.sleep(pSleepTime);
mProgressBar.setProgress(mProgress);
}
}

You may use Handler and Runnable.
Make the Handler execute postDelayed(yourRunnable, DELAY); in a new method called void next() or something.
In the run() method of yourRunnable, increase the progress position by X amount (very little, like 1 percent or something depending on your desire), and invalidate() your progress bar. After the progress bar increases the progress position by X amount, invoke next() again, which will, execute yourRunnable.run() again, which will increase the progress position by X amount (or you may gradually increase amount using a little more complex math, instead of static X amount), and so goes the cycle until the progress fills up to your desired amount.
private ProgressAnimator animator;
#Override
public void onDraw(Canvas c) {
super.onDraw(c);
if (animator.started) {
animator.next();
}
}
public void animateProgress(float end, IAnimator.PostAnimationAction postPostAnimationAction) {
animator.start(end, postPostAnimationAction);
}
private class ProgressAnimator {
static final long DELAY = 10;
// NOTE:
// "MULTIPLY_FACTOR" IS OPTIONAL.
// I USED THIS TO INCREASE THE PROGRESS SMOOTHLY AT
// DYNAMIC SPEED, NOT AT STATIC SPEED.
// IF YOU WANT STATIC INCREASE OF THE PROGRESS,
// DONT USE THIS.
static final float MULTIPLY_FACTOR = 0.2f;
float endPosition;
float remaining;
boolean started;
PostAnimationAction postAnimationAction;
Handler handler = new Handler();
Runnable runnable = new Runnable() {
#Override
public void run() {
if (Math.abs(remaining) > 1) {
raiseProgress(/* pass the current progress position here*/);
} else {
end();
}
}
};
/**
* Constructor.
*
*/
ProgressSweepAnimator() {
init();
}
#Override
public void init() {
started = false;
}
// NOTE:
// "PostPostAnimationAction" IS OPTIONAL. I CREATED AND USED THIS
// BECAUSE I WANTED TO DO SOMETHING AFTER THE PROGRESS
// ANIMATION IS FINISHED.
public void start(float endPosition, PostAnimationAction postPostAnimationAction) {
this.endPosition = endPosition;
start(postPostAnimationAction);
}
#Override
public void start(PostAnimationAction postAnimationAction) {
// Initialize status.
started = true;
this.postAnimationAction = postAnimationAction;
// Find out the current progress.
float start = /* get the current progress position here*/;
remaining = end - start;
raiseProgress(start);
}
#Override
public void next() {
handler.postDelayed(runnable, DELAY);
}
private void raiseProgress(float from) {
float toRaise = remaining * MULTIPLY_FACTOR;
remaining -= toRaise;
raiseProgressTo(from + toRaise);
}
#Override
public void end() {
raiseTo(end);
init();
// NOTE:
// THIS IS OPTIONAL BUT MAY BE VERY USEFUL, SO I
// JUST LEFT THIS OUT HERE.
// Notify the subscriber about the completion of the Burst action.
postAnimationAction.onActionComplete();
}
}
