我不明白什么时候ACTION_OUTSIDE被触发。请给我一个例子。

I don't understand when ACTION_OUTSIDE is triggered. Please give me an example.

该文档的给这个神秘的说明：

The doc's give this cryptic description:

常数的getAction（）：一个运动   已经发生了正常的外   用户界面元素的界限。这不   不能提供一个完整的手势，但只   的初始位置   移动/触摸。

Constant for getAction(): A movement has happened outside of the normal bounds of the UI element. This does not provide a full gesture, but only the initial location of the movement/touch.

推荐答案

我相信它仅用于点击当前的活动（例如一个对话框）之外。看看WindowManager.LayoutParams

I believe it is only used for clicking outside of the current activity (for example a dialog). Check out WindowManager.LayoutParams
