I'm writing a AccessibilityService and I want to create view overlays on the views from the current activity that the accessibility service can retrieve.

Unfortunately there are only few examples regarding accessibility services. Maybe some of you already have experience with this topic. I hope you can help me! Thanks!

推荐答案
您无法从其他应用程序获取 View 对象，因为 View 对象处于单独的过程中从你的.
You cannot get the View objects from other apps, as the View objects are in a separate process from yours.
