This solution works perfectly.

PS: You need to extends a Gallery.

@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
    int kEvent =
            e1.getX() < e2.getX() ? KeyEvent.KEYCODE_DPAD_LEFT : KeyEvent.KEYCODE_DPAD_RIGHT;
    onKeyDown(kEvent, null);
    return true;
}

for that you have create custom gallery you can refer the example here

to slow down fast navigation of your gallery try below code

yourGallery.setCallbackDuringFling(false);
