在所有其他Android应用顶部显示应用视图

Question

I have an app which enables users to set tasks with specific time deadlines. Once a deadline is passed, I want the app to show a view on top of everything (requesting the user to update the task).

My issues are: - how to show my app's view on top of every other activity that is currently active - how to keep the activity on top until the user updates the task?

Is using something like SYSTEM_ALERT_WINDOW look sensible?

您可以尝试创建一个透明的活动，将其打开并显示警报对话框。
