如何还原对话和敬酒的行为？

Question

I have the following problem: after an crash when resuming my VM suspended with AS open, the dialogs and Toasts now occupies the whole screen.

Before, they were just a little box that appeared on bottom of screen. Now ProgressDialogs, dialogs and toasts have that all screen behavior

I'm using appcompat-21 to use the toolbar control from Android Lollipop. What I have to look for?

Bellow the Manifest, the theme and styles files.

I've removed AS and reinstalled after passing an registry cleaner application (I'm on windows)

Android Manifest:

Answer 1

That's shameful (but educational) that the following item tag:

<style name="AppTheme" parent="Theme.ScannerTheme">
    <item name="android:background">@drawable/bi_background</item>
</style>

Is the cause of all trouble, because ALL dialogs get the background because of the app's theme.

The lesson is: beware what you put in your base theme definition...
