Android Layout - Adding Dynamic Textview and EditText - java

In one of my project I want to create a layout like given Image
In image assume that Red boxes are Textviews and Blue boxes are EditText
The number of rows is not known. It depends on web service Response. How can I achieve this.

You can try like this codes. Such as
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="match_parent"

android:layout_height="wrap_content"
android:layout_weight="3" >
<TextView

android:gravity="center"
android:text="First Row" />
</LinearLayout>
<LinearLayout

I expect it will be helpful for you. Best of luck!

Try adding views dynamically in linear layout which is inside scroll view.
Try this code.I know it is not exact solution.But,Hope it gives you some idea.
public class MainActivity extends Activity {
ScrollView scrollview;
LinearLayout linearLayout;
LinearLayout.LayoutParams layoutParams;
static int i;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
scrollview = (ScrollView)findViewById(R.id.scrollview);
linearLayout = (LinearLayout)findViewById(R.id.linearlayout);
Button button = (Button)findViewById(R.id.button);
layoutParams = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
button.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
TextView view = new TextView(MainActivity.this);
view.setText(++i+" view");
linearLayout.addView(view, layoutParams);
}
});
}}

first inf_child.xml layout:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout
android:id="#+id/inf_dynamicLl"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
</LinearLayout>
<LinearLayout
android:id="#+id/btnContainer"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<Button
android:layout_height="wrap_content"
android:layout_width="0dp"
android:layout_weight="0.25"
android:text="OK"/>
<Button
android:layout_height="wrap_content"
android:layout_width="0dp"
android:layout_weight="0.25"
android:text="Cancel"/>
</LinearLayout>
</LinearLayout>
second inf_dynamic_view.xml layout which will generate row dynamically:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/inner_linear_layout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
>
<TextView
android:id="#+id/firstText"
android:layout_width="0dp"
android:layout_weight="0.25"
android:layout_height="wrap_content"
/>
<TextView
android:id="#+id/secontText"
android:layout_width="0dp"
android:layout_weight="0.25"
android:layout_height="wrap_content"
/>
<TextView
android:id="#+id/ThirdText"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.25" />
<EditText
android:id="#+id/editText"
android:layout_height="wrap_content"
android:layout_width="0dp"
android:layout_weight="0.25"
/>
</LinearLayout>
if (convertView == null) {
LayoutInflater infalInflater = (LayoutInflater) mContext.getSystemService(mContext.LAYOUT_INFLATER_SERVICE);
convertView = infalInflater.inflate(R.layout.inf_child, null);
}
LinearLayout dynamicLl = (LinearLayout) convertView.findViewById(R.id.inf_dynamicLl);
for (int rowCounter = 0; rowCounter < parentData.get(groupPosition).childData.get(childPosition).price.size(); rowCounter++)
createRow(dynamicLl, parentData.get(groupPosition).childData.get(childPosition).price.get(rowCounter), groupPosition);
=> create row dynamically
private void createRow(LinearLayout lView, String price, int childPosition) {
LayoutInflater vi = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View l = vi.inflate(R.layout.inf_dynamic_view, null);
final TextView tvFirst, tvSecond,tvThird;
final EditText edt1;
lView.addView(l);
lView.refreshDrawableState();
}

Misaligned listview

I'm making a football league app, and i need to show the classification.
I'm trying to show a header that indicates what represents each field and a listview with the teams below.
I'm using a SimpleCursorAdapter to fill the list, but if the values have a different number of digits the list is misaligned. ¿How can i align it or at least add a 0 before the one-digit numbers with the adapter?
The soure code of the fragment and the xml:
ClassificacioFragment.java:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
String[] from = { EquipsContract.EquipEntry.COLUMN_NAME_NOM,
EquipsContract.EquipEntry.COLUMN_NAME_VICTORIES, EquipsContract.EquipEntry.COLUMN_NAME_DERROTES,
EquipsContract.EquipEntry.COLUMN_NAME_EMPATS, EquipsContract.EquipEntry.COLUMN_NAME_PUNTS};
int[] to = {R.id.item_nom, R.id.item_victories, R.id.item_derrotes, R.id.item_empats, R.id.item_punts};
View rootview = inflater.inflate(R.layout.fragment_classificacio, container, false);
ListView listView = (ListView) rootview.findViewById(R.id.classificacio);
listView.invalidateViews();
SimpleCursorAdapter adapter = new SimpleCursorAdapter(rootview.getContext(), R.layout.equip_row,
DBHandler.getDbInstance(getContext()).cursorClassificacio(), from, to);
listView.setAdapter(adapter);
String size = Integer.toString(DBHandler.getDbInstance(getContext()).getAllEquips().size());
Toast toast = Toast.makeText(getContext(), size, Toast.LENGTH_LONG);
toast.show();
return rootview;
}

You can simplify your ListView Row to use LinearLayout with weight parameters. It's more efficient and prevents issues with TextView's floating width.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:weightSum="9">
<TextView
android:id="#+id/item_nom"
android:layout_width="0dp"
android:layout_height="?android:attr/listPreferredItemHeight"
android:gravity="center_vertical"
android:textSize="20sp"
android:padding="2dp"
android:layout_marginStart="10dp"
android:layout_weight="4"
android:text="F.C. Barcelona"/>
<TextView
android:layout_width="0dp"
android:layout_height="?android:attr/listPreferredItemHeight"
android:layout_weight="1"
android:id="#+id/item_victories"
android:textSize="15sp"
android:text="10"
android:gravity="center"/>
<TextView
android:layout_width="0dp"
android:layout_height="?android:attr/listPreferredItemHeight"
android:layout_weight="1"
android:id="#+id/item_derrotes"
android:textSize="15sp"
android:text="20"
android:gravity="center"/>
<TextView
android:layout_width="0dp"
android:layout_height="?android:attr/listPreferredItemHeight"
android:layout_weight="1"
android:id="#+id/item_empats"
android:textSize="15sp"
android:text="30"
android:gravity="center"/>
<TextView
android:layout_height="?android:attr/listPreferredItemHeight"
android:layout_width="0dp"
android:layout_weight="2"
android:id="#+id/item_punts"
android:textSize="18sp"
android:text="40"
android:gravity="center"/>
</LinearLayout>

At first all of your text in the TextView must be center aligned.
android:gravity="center"
Then, pogramatically you should find the largest TextView and set the width of each other TextView in that row.
Or you use TableLayout ;)

Create a function for appending 0 with numbers less than 10.
public String appendZero(int input) {
if (input >= 10) {
return String.valueOf(input);
} else {
return "0" + String.valueOf(input);
}
}
While setting the text, call like this :
item_victories.setText(appendZero(victory_count.get(position)));
Hope this one will works for you.

How to access views from the programatically inflated layouts?

Download this library https://github.com/plattysoft/Leonids
Add this to your project dependency
then
new ParticleSystem(RainActivity.this, 80, R.drawable.rain_drop, 10000)
.setSpeedByComponentsRange(0f, 0f, 0.05f, 0.1f)
.setAcceleration(0.00005f, 90)
.emitWithGravity(findViewById(R.id.cloud), Gravity.BOTTOM, 8);
It will look like

logcat error line 78 : spinner1.setadapter(adapter);
enter code here09-03 11:25:46.344: E/AndroidRuntime(7841): Caused by: java.lang.NullPointerException

any suggestions are appreciated

You are trying to retrieve Views from Activity, but they are in Fragment.
getActivity().findViewById(R.id.yourId); is what you should do whenever you are using findViewById() method.

The NullPointerException is not a problem with instantiating your adapter, but rather with the way you are getting the Spinner.
If the spinner exists in the fragment you need to specify its context as so.
just putting findViewById() is really this.findViewById(), where this is your activity. In other words your telling the method to find views in the content view of the activity.
If the spinner is in the content view of the fragment, you need to instead use
fragment.getActivity().findViewById(R.id.???);
this way findViewById() knows to find your spinner in the context of the fragment.
Hope this helps!

imageswitcher fills screen (but I dont want it to do that) [android]

I have added an imageswitcher to my register fragment, when the user select his/her gender the image changes but the image shown is too big and I cant scale it. I am using a scrollview and it is not good that the Imageswitcher is bigger than screen. I tried using smaller images but the result is same. Here is my XML:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"

and the code for the imageswitcher:
....
cinsiyetSwitcher = (ImageSwitcher) rootView.findViewById(R.id.cinsiyetSwitcher);
cinsiyetSwitcher.setFactory(new ViewFactory() {
#Override
public View makeView() {
ImageView imageView = new ImageView(getActivity());
imageView.setScaleType(ImageView.ScaleType.CENTER);
imageView.setLayoutParams(new ImageSwitcher.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT));
return imageView;
}
});
kizRadio = (RadioButton) rootView.findViewById(R.id.radio0);
erkekRadio = (RadioButton) rootView.findViewById(R.id.radio1);
kizRadio.setOnClickListener( new View.OnClickListener() {
public void onClick(View v)
{
degistir1(v);
}
});
erkekRadio.setOnClickListener( new View.OnClickListener() {
public void onClick(View v)
{
degistir2(v);
}
});
....
...
public void degistir1(View view)
{
Animation in = AnimationUtils.loadAnimation(getActivity(),
android.R.anim.slide_in_left);
Animation out = AnimationUtils.loadAnimation(getActivity(),
android.R.anim.slide_out_right);
cinsiyetSwitcher.setInAnimation(in);
cinsiyetSwitcher.setOutAnimation(out);
cinsiyetSwitcher.setImageResource(R.drawable.kari);
}
public void degistir2(View view)
{
Animation in = AnimationUtils.loadAnimation(getActivity(),
android.R.anim.slide_out_right);
Animation out = AnimationUtils.loadAnimation(getActivity(),
android.R.anim.slide_in_left);
cinsiyetSwitcher.setInAnimation(out);
cinsiyetSwitcher.setOutAnimation(in);
cinsiyetSwitcher.setImageResource(R.drawable.adam);
}
