View only registration MotionEvent.ACTION_DOWN

I have an interesting problem ... I can not find a solution. I use ObjectAnimator to rotate ImageView; but onTouchListener seems to register MotionEvent.ACTION_DOWN. (I deduced this from Log Cats, there is also MotionEvent.ACTION_MOVE and MotionEvent.ACTION_UP).

I thought that maybe the problem is related to trying to listen and animate the camera at the same time. I wrapped both the image and the linear layout (set in MATCH PARENT) in a relative layout and registered a linear layout for listening to touch events. Line layout has the same problem; only MotionEvent.ACTION_UP is processed. Is there something I need to register for MotionEvent.ACTION_MOVE?

Here is my code:

            touch_pad = (LinearLayout) findViewById(R.id.layout_touch_capture);
    touch_pad.setOnTouchListener(this);
    touch_pad.requestFocus();

            public boolean onTouch(View v, MotionEvent event) {
    switch(v.getId()) {
    case (R.id.layout_touch_capture):

    long end = 0;
    long start = 0;
    float y = event.getY();
    float y_sum = y;
    float x = event.getX();

    switch(event.getAction()) {
    case (MotionEvent.ACTION_UP): 
        end = animator.getCurrentPlayTime();
    Log.d("WheelActivity", "end location = " + end);
    break;
    case (MotionEvent.ACTION_MOVE):

    Log.d("WheelActivity", "event.getY() = " + y);
    y_sum += y;
    animator.setCurrentPlayTime((long) (start + y_sum));
    Log.d("WheelActivity", "animator play time = "                               animator.getCurrentPlayTime());
    Log.d("WheelActivity", "animator fraction = " +
          animator.getAnimatedFraction());

    break;
    case (MotionEvent.ACTION_DOWN): 
        start = animator.getCurrentPlayTime();
    Log.d("WheelActivity", "start location = " + start);
    break;
    }   
    }
    return false;
}
