Hi all,
I want to set default focus in the first focusable view when entering
a new screen, and i use view.requestFocus(View.FOCUS_DOWN) (view is
the root ViewGroup), but it doesn't work. The method alway return
false. And i also found a strange situation: view.getFocusables
(View.FOCUS_DOWN) will return several focusabel views, but
view.focusSearch(View.FOCUS_DOWN) returns null. Then i try followed:
ArrayList<View> al = view.getFocusables(View.FOCUS_DOWN);
if(al != null && al.size() > 0)
{
al.get(0).requestFocus();
}
It solves the problem, now can focus to the first focusable child
view. However it looks strange, and not smart. Do any one have any
other smart methods?
