推荐答案

返回值决定，如果你消耗的触摸事件。

The return value determines if you consumed the touch event.

在换句话说真意味着这个触摸事件有趣的是，你都遵循了这个触摸事件类似的电话 ACTION_MOVE 或 ACTION_UP 将被发送给您。

In other words true means that this touch event is interesting to you and all follow up calls of this touch event like ACTION_MOVE or ACTION_UP will be delivered to you.

如果您返回假比触摸事件将被传递到下一个查看进一步在视图层次您将收到任何来电跟进。触摸事件将继续向上视图层次进一步传递，直到有人占用了。

If you return false than the touch event will be passed to the next View further up in the view hierarchy and you will receive no follow up calls. The touch event will continue to be passed further up the view hierarchy until someone consumes it.
