Create a transparent dialog on top of activity

Question

Background

I\'m trying to put a layer on top of the current activity which would have explanation of what is going on on the current screen, similar to what occurs on

Answer 1

Just add this, it really works!

<item name="android:windowIsTranslucent">true</item>
        <item name="android:windowCloseOnTouchOutside">true</item>
        <item name="android:windowBackground">@android:drawable/alert_dark_frame</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>

Answer 2

Just change the background color of your Dialog:

dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

Edit:

This prevents the dim effect:

dialog.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
