I have a custom ViewGroup that inflates a ListView from an xml layout. The list item layout is inflated from another xml file. All of the views are set to fill_parent. The ListView fills its parent, but the ListView items don't.
I've tried putting the ListView in a LinearLayout and assigning weight to it. Tried RelativeLayout as well. Also, I've built the ListView programmaticaly, without using the xml layout. Even changed the LayoutParams before adding the view to the ViewGroup.
I've also taken in consideration these posts as well: Width of clickable area in ListView w/ onListItemClick, In Android, how can I set a ListView item's height and width?, Android Listview width prob.
Any ideas to why the items don't extend to fill width? And how to extend them?
MyViewGroup class:
public class MyViewGroup extends ViewGroup {
public MyViewGroup(Context context, AttributeSet attrs) {
super(context, attrs);
generateMyViewGroup();
}
private void generateMyViewGroup()
{
ListView main = (ListView) View.inflate(getContext(), R.layout.layout_main, null);
main.setAdapter(new MyAdapter(getContext()));
this.addView(main);
}
@Override
protected void onLayout(boolean changed, int l, int t, int r, int b) {
this.getChildAt(0).layout(l, t, r, b);
}
}
ListView xml layout:
<?xml version="1.0" encoding="utf-8"?>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginRight="3dp"
android:background="#77000000"
android:cacheColorHint="#00000000"
android:divider="#00000000"
android:dividerHeight="0dp"
android:drawSelectorOnTop="false"
android:scrollbars="vertical" >
</ListView>
ListView item layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/layout_main_category"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@color/mainBackground"
android:gravity="fill_horizontal|center_vertical"
android:orientation="vertical" >
<TextView
android:id="@+id/main_category"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="8dp"
android:layout_marginRight="8dp"
android:paddingBottom="7dp"
android:paddingLeft="20dp"
android:paddingRight="5dp"
android:paddingTop="20dp"
android:text="test"
android:textColor="@color/mainCategory"
android:textSize="15sp"
android:textStyle="bold" />
</LinearLayout>
