Full Screen Theme for AppCompat

I would like to know how can I apply full screen theme ( no title bar + no actionbar ) to an activity. I am using AppCompat library from support package v7.

I've tried to applied

android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
to my specific activity but it crashed. I think it's because my application theme is like this.

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">


I also have tried this

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);


which only hides title bar but not the action bar.
My current workaround is that hiding the actionbar with

getSupportActionBar().hide();

Answer

When you use Theme.AppCompat in your application you can use FullScreenTheme by adding the code below to styles.

<style name="Theme.AppCompat.Light.NoActionBar.FullScreen" parent="@style/Theme.AppCompat.Light">
    <item name="windowNoTitle">true</item>
    <item name="windowActionBar">false</item>
    <item name="android:windowFullscreen">true</item>
    <item name="android:windowContentOverlay">@null</item>
</style>
