ScrollView.fullScroll(int direction):

Handles scrolling in response to a "home/end" shortcut press. This method will scroll the view to the top or bottom and give the focus to the topmost/bottommost component in the new visible area. If no component is a good candidate for focus, this scrollview reclaims the focus.

方向： View.Focus_Up,Focus_Down,Focus_Left,Focus_Right,水平滚动的将使用Focus_Left,Focus_Right，垂直的使用View.Focus_Up,Focus_Down.

对ScrollView.fullScroll()的调用，应该这样

postDelayed(new Runnable() {
            @Override
            public void run() {
                view.fullScroll(ScrollView.FOCUS_RIGHT);
            }
        },100L);

如果直接调用可能会无效，所以让其延迟下。android中经常使用消息队列来同步.
