查看只有注册MotionEvent.ACTION_DOWN

我有一个有趣的问题......我似乎无法找到解决方案。我使用ObjectAnimator旋转ImageView;但是onTouchListener只能注册MotionEvent.ACTION_DOWN。（我从Log Cats中推导出来，还有MotionEvent.ACTION_MOVE和MotionEvent.ACTION_UP）。查看只有注册MotionEvent.ACTION_DOWN

我想也许这个问题与试图在同一时间试听和动画的问题有关。我在相对布局中包装了imageview和线性布局（设置为MATCH PARENT），并注册了线性布局以侦听触摸事件。线性布局具有相同的问题;只有MotionEvent.ACTION_UP正在处理中。有什么我需要去获得MotionEvent.ACTION_MOVE注册？

这里是我的代码：

  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; 
}

（很抱歉的格式混乱的代码...）

return false;

变更为return true;
