Detecting whether touch event has occurred in android?

Question

I am developing an android application, in which, I am changing the image continuously in intervals. Before every change, I need to check if touch event has occurred or not? If yes, then which event has occurred, DOWN or UP?

In my search I only found how to add touch event and check which event occurred, but I couldn't find a solution which would enable me to know if event has occurred or not.

Can Someone Help me in this?

Copy paste this in your java code

public class yourActivity extends FragmentActivity implements View.OnTouchListener {
ImageView yourpic;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

yourpic = (ImageView) findViewById(R.id.yourpicID);
 yourpic.setOnTouchListener(this);
}

@Override
public boolean onTouch(View v, MotionEvent event) {

    ImageView view = (ImageView) v;

switch (event.getAction()) {
                case MotionEvent.ACTION_DOWN:                                  
                    break;
                case MotionEvent.ACTION_MOVE:
                    break;
                case MotionEvent.ACTION_UP:
                    break;
                case MotionEvent.ACTION_CANCEL:
                    break;
            }
            break;
}
return true;
}
