How to detect the gesture of the customed view, the user actually touch?

Question

Hi guy

I am trying write a reusable custom view to move it on screen according to user gesture. How can I do that? I tried to write based on some example, I found that I can only listen only one object.

here is my main activity code.

Please help!

public class GestureFunActivity extends Activity implements OnTouchListener, OnGestureListener {
/** Called when the activity is first created. */

private PlayAreaView view;
private GestureDetector mGestureDetector;
public GestureFunActivity() {
    mGestureDetector = new GestureDetector(this);
}

@Override
public void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   setContentView(R.layout.main);
   FrameLayout frame =  (FrameLayout)  findViewById(R.id.graphics_holder);
   PlayAreaView image = new PlayAreaView(this);
   image.setOnTouchListener(this);
   image.setContentDescription("image");
   Log.i("MyGesture", "onCreate" + image.getContentDescription().toString());
   frame.addView(image);
}


public boolean onTouch(View v, MotionEvent event) {
    view = (PlayAreaView) v;
    Log.i("MyGesture", "onTouch [" + v.getContentDescription().toString() + "]");
    Toast.makeText(this, "onTouch [" +  v.getContentDescription().toString() +"]" , Toast.LENGTH_SHORT).show();
    return mGestureDetector.onTouchEvent(event);
}


public boolean onDown(MotionEvent arg0) {
    Log.i("MyGesture", "onDown" );
    return true;
}


public void onShowPress(MotionEvent e) {
    Log.i("MyGesture", "onShowPress");
}


public boolean onSingleTapUp(MotionEvent e) {
    Log.i("MyGesture", "onSingleTapUp");
    return true;
}

public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {

    final int FLING_MIN_DISTANCE = 10, FLING_MIN_VELOCITY = 20;
    if (e1.getX() - e2.getX() > FLING_MIN_DISTANCE && Math.abs(velocityX) > FLING_MIN_VELOCITY) {
        // Fling left
        Log.i("MyGesture", "Fling left");
    } else if (e2.getX() - e1.getX() > FLING_MIN_DISTANCE && Math.abs(velocityX) > FLING_MIN_VELOCITY) {
        // Fling right
        Log.i("MyGesture", "Fling right");
    }


        final float distanceTimeFactor = 0.4f;
        final float totalDx = (distanceTimeFactor * velocityX/2);
        final float totalDy = (distanceTimeFactor * velocityY/2);

        view.onAnimateMove(totalDx, totalDy,
                (long) (10 * distanceTimeFactor));
    //    return true;


    return false;
}


public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) {
    Log.i("MyGesture", "onScroll");
    return true;
}


public void onLongPress(MotionEvent e) {
    Log.i("MyGesture", "onLongPress");
} 

}
