Added in API level 23

void onGetContentRect (ActionMode mode, 
                View view, 
                Rect outRect)

当ActionMode需要在屏幕上定位时调用，可能会遮挡视图内容。注意这可能会在每帧的基础上调用。

Parameters
`mode`	`ActionMode`: The ActionMode that requires positioning.
`view`	`View`: The View that originated the ActionMode, in whose coordinates the Rect should be provided.
`outRect`	`Rect`: The Rect to be populated with the content position. Use this to specify where the content in your app lives within the given view. This will be used to avoid occluding the given content Rect with the created ActionMode.
