使用 WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH 获取所有 MotionEvent
我的问题直接涉及这个问题。该问题的答案展示了如何创建一个 ViewGroup，将其嵌入到 WindowManager 中，并允许 WindowManager 捕获 MotionEvent 通过onTouchEvent(MotionEvent event)。 WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH 是允许此 ViewGroup 接收 MotionEvent 的标志。然而，根据文档，这个标志
...不会收到完整的向下/移动/向上手势
我想知道是否有解决方法或方法，以便我可以获得所有触摸事件，包括向下、移动和向上。概念验证位于应用Wave Launcher中它使用相同的概念，但能够接收多个 ACTION_OUTSIDE 事件。
My question refers directly to this question. The answer to that question shows how one can create a ViewGroup, embed it inside a WindowManager, and allow the WindowManager to catch MotionEvents through onTouchEvent(MotionEvent event). WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH is the flag that allows this this ViewGroup to receive MotionEvents. However, according to documentation, this flag
...will not receive the full down/move/up gesture
I want to know if there's a work-around or a way so that I can get all touch events including down, move, and up. A proof of concept is in the app Wave Launcher which uses the same concept but is able to receive more than just a single ACTION_OUTSIDE event.

不，你不能，这很大程度上是设计使然。
Wave Launcher 不会这样做，它有一个 UI 元素，您可以在其中启动触摸手势，然后与标准一样，甚至分派所有触摸事件都会传递到第一个向下点的窗口，直到最后向上。
No you can not, and that is very much by design.
Wave Launcher doesn't do this, it has a UI element where you start your touch gesture and then as with standard even dispatching all touch events are delivered to the window of the first down point until the final up.
