setIndicatorBounds(int, int) does not work properly for Android 4.3.
They introduced a new method setIndicatorBoundsRelative(int, int) which works ok for 4.3.
@Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
if(android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.JELLY_BEAN_MR2) {
mExpandableListView.setIndicatorBounds(myLeft, myRight);
} else {
mExpandableListView.setIndicatorBoundsRelative(myLeft, myRight);
}
}
