Question

Is there a sane way to programatically scroll to show a specific component in a Gallery – the equivalent of setSelection(int) but with smooth scrolling rather than a direct jump?

Answer 1

I think I’ve found an easy way to do it ! It consists of calling the onFling() method directly…

MotionEvent e1 = MotionEvent.obtain(
    SystemClock.uptimeMillis(), 
    SystemClock.uptimeMillis(),  
    MotionEvent.ACTION_DOWN, 89.333336f, 265.33334f, 0);
MotionEvent e2 = MotionEvent.obtain(
    SystemClock.uptimeMillis(), 
    SystemClock.uptimeMillis(), 
    MotionEvent.ACTION_UP, 300.0f, 238.00003f, 0);

gallery.onFling(e1, e2, -800, 0);

There should be a better way to do it. onFling() should be called when the Gallery gets flinged, not to fling it.
