Just use

public class CustomGallery extends Gallery {

private Handler handler;

public CustomGallery(Context context) {
    super(context);
    handler = new Handler();
    postDelayedScrollNext();
}

public CustomGallery(Context context, AttributeSet attrs) {
    super(context, attrs);
    handler = new Handler();
    postDelayedScrollNext();
}
public CustomGallery(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
    handler = new Handler();
    postDelayedScrollNext();
}

protected void postDelayedScrollNext() {
    handler.postDelayed(new Runnable() {
        public void run() {
            postDelayedScrollNext();
            Log.d("CustomGallery", "dpad RIGHT");
            onKeyDown(KeyEvent.KEYCODE_DPAD_RIGHT, null);
        }
    }, 1000);
}

protected boolean isScrollingLeft(MotionEvent e1, MotionEvent e2) {
    return e2.getX() > e1.getX();
}

public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
    int kEvent;
    if (isScrollingLeft(e1, e2)) {
        Log.d("CustomGallery", "fling LEFT");
        kEvent = KeyEvent.KEYCODE_DPAD_LEFT;
    } else {
        Log.d("CustomGallery", "fling LEFT");
        kEvent = KeyEvent.KEYCODE_DPAD_RIGHT;
    }
    onKeyDown(kEvent, null);
    return true;
}
}
