Solution to Android return false in (0)

Sometimes we want the first line of the listview to automatically get the focus, so we will use (0) to operate, but sometimes it does not take effect. After debugging, rerurn is false.

This is because we get focus too early and the listview control is still loaded. You can try a solution:

(new Runnable(){
@Override 
public void run(){
(0);
}
});
