I have two radiobutton groups that need to be initialized when loading the screen, so I used this code:
mVisibilityPublic.setChecked(true);
But when I load the screen I get the following (first is the wrong behavior, second is the expected one):
I've tried with all these:
mVisibilityPublic.setSelected(true);
mVisibilityPublic.performClick();
mVisibilityPublic.setActivated(true);
mVisibilityPublic.invalidate();
mVisibilityPublic.requestLayout();
But I get the same result.

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.

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.
I have an activity in which I have inflated another layout. OnClick of next destination I am getting inflated a new layout. Now I want to remove the inflated layout. So I want to access the linear layout of remove from inside inflated layout. How can I access this??
Layout looks like this :
I have achieved to inflate layout and remove the first destination from parent which is a part of parent layout. Now I want to do same with inflated destination layout. onClick of remove the inflated layout should get removed.

java code used to show snake bar
private CoordinatorLayout _CoordinatorLayout;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.compition, null);
_CoordinatorLayout = (CoordinatorLayout) v.findViewById(R.id.fullview);
}
Snackbar.make(_CoordinatorLayout , message , Snackbar.LENGTH_LONG).show();
here is screen shot
what I miss ??
The documentation here says:
Snackbars appear above all other elements on screen and only one can
be displayed at a time.
So, Snackbar will cover your view, just like a Toast.
In one of my project I want to create a layout like given Image

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: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);
