Android: Programmatically animate between images in Gallery widget

Question

Note: As of Jellybean the gallery widget is deprecated. A ViewPager should be used instead.

I\'d like to programmatically move between images in the Gallery wi

Answer 1

Just call the key press handler for the gallery directly:

public boolean onKeyDown(int keyCode, KeyEvent event)

i.e

Gallery gallery = ((Gallery) findViewById(R.id.gallery));

gallery.onKeyDown(KeyEvent.KEYCODE_DPAD_LEFT, new KeyEvent(0, 0));

One important thing - this solution works only if child that is on left/right was already created, which means that it has to be 'visible'. If you have your image on fullscreen - consider setting spacing to -1 value.
