Why the SetSelection of the ListView is invalid-turn

Reason one: The ListView loses focus after the interface initialization is complete.

Reason two: Because the item height of the ListView is inconsistent, or the Headerview is added, the call setselection after Setadapter cannot be accurately located.

Universal Solution:

[Java]View Plaincopy

1. Final ListView listview = New ListView (Getactivity ());
2. Listview.post (new Runnable () {
3. @Override
4. public Void Run () {
5. Listview.requestfocusfromtouch (); //Get Focus
6. Listview.setselection (Listview.getheaderviewscount () +10);
7. }
8. });

If not, it's okay.
