I have a dialog popping up with a title and a close button. This is the XML:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:gravity="center_vertical">
<TextView
android:id="#+id/text_title"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_marginLeft="24dp"
android:layout_marginRight="0dp"
android:layout_marginTop="16dp"
android:layout_marginBottom="16dp"
android:maxLines="1"
<!--- android:singleLine="true" <-- Do not comment about this, it is deprecated --->
android:ellipsize="marquee"
android:marqueeRepeatLimit="marquee_forever"
android:scrollHorizontally="true"
android:focusable="true"
android:focusableInTouchMode="true"
android:textSize="20sp"
android:textColor="#android:color/black"
/>
<ImageView
android:id="#+id/backburger"
android:layout_width="32dp"
android:layout_height="32dp"
android:layout_marginStart="24dp"
android:layout_marginEnd="24dp"
android:layout_marginTop="16dp"
android:layout_marginBottom="16dp"
android:src="#drawable/ic_close"
android:foreground="?android:attr/selectableItemBackground"
/>
</LinearLayout>
Like you can see the TextView has all the things it needs for a marquee, the singleLine options is deprecated, so I can't use it. I do call setSelected(true) in my Java. There are lots of questions about a marquee, but none with layout_weight and from '17.
This is the preview of the XML:
Try this one:
In your Xml:
<TextView
android:id="#+id/text_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:maxLines="1"
android:ellipsize="marquee"
android:fadingEdge="horizontal"
android:marqueeRepeatLimit="marquee_forever"
android:scrollHorizontally="true"
android:textSize="20sp"
android:textColor="#android:color/black" />
and your Code:
tv = (TextView) this.findViewById(R.id.text_title);
tv.setSelected(true);
Hope its help:)
public void setticker(String text, TextView view) {
if (text != "") {
view.setText(text);
//view.setTextSize(25.0F);
Context context = view.getContext(); // gets the context of the view

// before it is drawn in the layout
view.measure(View.MeasureSpec.UNSPECIFIED,

float screenWidth = ((Activity) context).getWindowManager()

} else {

first remove final keyword from your TextView Object
this code
final TextView tv4 = (TextView) findViewById(R.id.tv4);
Replace
TextView tv4 = (TextView) findViewById(R.id.tv4);
then you can set color
you can write hex code
tv4.setTextColor("#ffffff");
or yuu can write color name
tv4.setTextColor(Color.WHITE);
or you can call it from color.xml file
tv4.setTextColor(getResources().getColor(R.color.your_colour));
Quite simple
tv4.setTextColor(Color.RED);
Or if you have a speific colour resource
tv4.setTextColor(ContextCompat.getColor(getApplicationContext(), R.color.your_colour));
tv4.setTextColor(getResources().getColor(R.color.your_colour));
Update:
Decare your view elements globally outside of onCreate
public class MainActivity extends Activity {
private EditText e1;
private EditText e2;
private TextView tv4;
#Override
protected void onCreate(Bundle savedInstanceState) {
// ...
e1 = (EditText) findViewById(R.id.et1);
e2 = (EditText) findViewById(R.id.et2);
tv4 = (TextView) findViewById(R.id.tv4);
}
Its Quite easy
1)Find Reference to Text View of which you want to change color
2)Use Method
MytextView.setColor(Color.BLUE);
Or if you have defined your custom color in colors.xml file
MytextView.setColor(getResourses().getColor(R.color.Mycolor));
I have a TableLayout which is dynamically populated. On getting to the page, it shows as expected but the moment I switch away from the app or a call comes in, the layout is distorted, resulting in inconsistent column width as shown in the images below.

What is it that I'm doing wrong? How do I maintain equal column width irrespective of whether the user switch away and come back to the app or stayed on it for long.
Reloading data onResume() works well for me. Thanks #SumitShukla
I have a problem and I can't solve it, I will appreciate it if somebody would help me. I want to put two images on the top of the screen. Both images should have width = screen_width/2 (just because when the screen is smaller, images should resize).I've tried this, but it isn't enough. Thank you!

Use LinearLayout instead/inside RelativeLayout and set the weight property to 0.5 in each child view. you should also use layout:gravity to set the child view on the top.
Try this:
private int columnWidth;
//get Screen Size
public int getScreenWidth() {
int columnWidth ;
WindowManager wm = (WindowManager) this
.getSystemService(Context.WINDOW_SERVICE);
Display display = wm.getDefaultDisplay();
final Point point = new Point();
try {
display.getSize(point);
} catch (java.lang.NoSuchMethodError ignore) { // Older device
point.x = display.getWidth();
point.y = display.getHeight();
}
columnWidth = point.x;
return columnWidth;
}
//set height and width of Imageview
int height=columnWidth;
int width=columnWidth;
img.setLayoutParams(new RelativeLayout.LayoutParams(height,width));
Hope this may help you
I am trying to create a line between 2 ImageButtons on screen. I have the buttons placed on the screen in an xml file and I am trying to code a way to draw a set of lines that will correctly scale when I use a different screen size. When I try to use getX() it states that the returned values are all 0. Is there some way I'm missing to get the x and y values of where I placed the buttons in the xml? Do I have to put the line in manually for each different screen size?

You can create a line by adding a view to your xml.
Vertical line:
<View
android:layout_width="1dip"
android:layout_height="fill_parent"
android:background="#FF0000FF"
/>
Horizontal line:
<View
android:layout_width="fill_parent"
android:layout_height="1dip"
android:background="#FF0000FF"
/>
Adjust the background color to your desired line color.
I need to apply a translation animation to an ImageView, this ImageView is positioned at certain place and i need to animate it to the center of the screen. Here is my translate xml code, but it doesn't animate the ImageView to the center.
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >

android:fromXDelta="0%p"

Have a look at this question. I gave a similar answer but the animation is not from an xml but from code. Hope it helps.
EDIT:
Your problem is that the animation doesn't take into account the image dimensions. The animation is centering the origin coordinate of your ImageView.
I still suggest my solution.
I tried the code in the answer that I linked and it works. Just copy this function:
private void moveViewToScreenCenter( View view )
{
RelativeLayout root = (RelativeLayout) findViewById( R.id.WelcomeLayout );
DisplayMetrics dm = new DisplayMetrics();
this.getWindowManager().getDefaultDisplay().getMetrics( dm );
int statusBarOffset = dm.heightPixels - root.getMeasuredHeight();
int originalPos[] = new int[2];
view.getLocationOnScreen( originalPos );
int xDest = dm.widthPixels/2;
xDest -= (view.getMeasuredWidth()/2);
int yDest = dm.heightPixels/2 - (view.getMeasuredHeight()/2) - statusBarOffset;
TranslateAnimation anim = new TranslateAnimation( 0, xDest - originalPos[0] , 0, yDest - originalPos[1] );
anim.setDuration(1000);
anim.setFillAfter( true );
view.startAnimation(anim);
}
and call it passing your view as the parameter:
ImageView img1 = (ImageView) findViewById( R.id.welcome_innovaLogo );
moveViewToScreenCenter(img1);
If your image still disappear, maybe is because it is behind your other widgets, like the ListView. If that is the case, reestructure your xml layout definig the ImageView at the end, just after the Listview (just cut and paste the ImageView).
For future updates...
Apply view property animation to move position of widget. Image view in this case
int layoutWidth = parentLayout.getWidth();
layoutWidth = ((int) layoutWidth / 2) - (imageView.getWidth()) ;
Log.d(TAG, " position - " + layoutWidth);
imageView.animate()
.translationX(-layoutWidth)
.translationY(0)
.setDuration(500)
.setInterpolator(new LinearInterpolator())
.start();
Try adding delay to this code.
new android.os.Handler().postDelayed(
new Runnable() {
public void run() {
moveViewToScreenCenter( view );
}
},
1000);
