Android 为什么onDrag方法运行数百万次？

我试图在我的项目中实现一个小小的拖放系统，到目前为止，我已经：

@Override
    public boolean onDrag(View eventView, DragEvent event) {

    final int action = event.getAction();

    switch (action) {

    case DragEvent.ACTION_DRAG_STARTED:

        DragAndDropState.itWasDropped = false;

        draggedView = (View) event.getLocalState();

        if (draggedView.getParent() != null) {


            draggedTargetParent = (View) draggedView.getParent();
            DragAndDropState.dragStartPosition = (Integer) draggedTargetParent.getTag();

            Log.i("START draggedView ", draggedView.toString());
            Log.i("START parent: ", draggedTargetParent.toString());

        }



        ((ViewGroup) eventView).removeView((View) event.getLocalState());

        return true;


    case DragEvent.ACTION_DROP: //............... more code

我点击了一个视图后在logcat中看到：

09-03 14:08:48.236: I/START draggedView(12796): hu.fun.views.slot.ItemInSlotView@42ae2ef0
    09-03 14:08:48.236: I/START parent:(12796): hu.fun.views.slot.Slot@42ab7e68

    09-03 14:08:48.246: I/START parent:(12796): hu.fun.views.slot.Slot@42ab7e68
    09-03 14:08:49.137: I/ViewRootImpl(12796): Reporting drop result: true

没错我得到了6（六！）onDragEvents，通过一次长点击触发，并在一个目标视图上使用一次长点击列表

有谁能解释我为什么会这样，或者为什么这样好

我真的很想只做其中一件事，用这样的消息充斥logcat纯粹是一种注释，我无法用这样的方式进行调试。

代码中的break语句在哪里。它应该在操作之前出现。@hamad如果有返回，您不需要中断。请提供更多的代码，以便我们能够很好地理解它。。！！！
