Android ACTION_UP即使返回true也不起作用

Question

我尝试在onTouch方法中使用MotionEvent但是......它永远不会起作用

我还在google上搜索过，发现在onTouch方法中它需要返回true。

我做了但仍然不行......

任何想法？...

        imageViewCancel.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View view, MotionEvent event) {
            Log.d(TAG, "ACTION : " +  event.getAction());
            switch(event.getAction()){
                case MotionEvent.ACTION_UP:
                    Log.d(TAG, "ACTION UP");
                    view.setVisibility(View.VISIBLE);
                    break;
                case MotionEvent.ACTION_DOWN:
                    Log.d(TAG, "ACTION DOWN");
                    ClipData data = ClipData.newPlainText("", "");
                    View.DragShadowBuilder shadowBuilder = new View.DragShadowBuilder(
                            view);
                    view.startDrag(data, shadowBuilder, view, 0);
                    view.setVisibility(View.INVISIBLE);
                    break;

                default:
                    break;
            }
            return true;
        }
    });
