Android suspended window shields the instance code of all click events outside the suspended window

Android can add a view above all applications, that is, add a view to WindowManager. When creating a view, you can set the layoutparams (Android. View. WindowManager. Layoutparams. Layoutparams()) property for the view. By default, all click events outside the view area are blocked, that is, when the view is displayed, other areas of the screen are not clickable, Including menu and return key, etc. After setting the appropriate flag for layoutparams, other areas can respond to clicks.

Example code:

This line of code controls the area outside the view to respond to click and touch events. If flag is not set, areas outside view cannot respond
