使用windowmanager，我使应用程序在主屏幕上像facebook messenger一样显示。
motionevent允许移动浮动视图。我想设置windowmanager标志，并为浮动屏幕以外的屏幕获取触摸事件，但它不起作用。。。
当我触摸浮动视图时，它工作得很好。通过调用ontouchlistener，action\u down action\u up，
当我触摸窗外（主屏幕）时，我希望它能很好地完成其他工作（触摸其他应用程序）和呼叫侦听器。请任何人指导我如何在我的应用程序中获取触摸事件，以便我可以执行一些任务。我用了三个全旗旗、旗帜、手表、户外、触摸旗、非触摸模式
标志不可聚焦
flag_not_focusable| flag_not_touch_model
在主屏幕上，它触摸窗口的其余部分，但无法调用onclicklistener的触摸。
除浮动视图外的标志\u手表\u外部触摸触摸被阻止。
