如何在Android 6.0上使用Theme.AppCompat.Light.Dialog？

Question

I want to display activity which should look like dialog. I'm using theme inherited from Theme.AppCompat.Light.Dialog to achievie that . This solution works quite well on Android 4.x and Android 5.x. Unfortunately on Android 6 it doesn't. I see black background instead of nice transparency.

Theme code:

<style name="AppTheme.Popup" parent="Theme.AppCompat.Light.Dialog">
        <item name="windowNoTitle">true</item>
</style>

Activity code - just extended from AppCompatActivity

I was trying to fix using some another settings:

    <item name="android:windowIsTranslucent">true</item>
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:backgroundDimEnabled">false</item>

Without any success :(

I think you need to sub theme Theme.AppCompat.Light.Dialog.Alert not Theme.AppCompat.Light.Dialog , so your theme will be like:

<style name="AppTheme.Popup" parent="Theme.AppCompat.Light.Dialog.Alert">
        <item name="windowNoTitle">true</item>
</style>
