将父活动的自定义对话框覆盖到所有视图，包括android中的子活动

Question

I need to show a custom dialog overlays over all child activities. But that dialog's base context is background. Is it possible?. This is used for custom lock to whole application after wake up(Screen On). I have a broad cast receiver to manage that. But that receiver is registered through parent activity. When the screen go to sleep from parent activity that dialog/process executes correctly. But the screen go to sleep from child activity that dialog shows background of child activity, when I will back to the parent activity then that shows. I think this occurred on dialog's context.

Answer 1

You need to use an Activity instead of a Dialog . Set your Activity theme to emulate a Dialog in the manifest.

Example - AndroidManifest.xml:

android:theme="@android:style/Theme.Dialog"

Then, you will have more flexibility and control over its display.
