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();
Solution

  • 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.NoActionBar">
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowActionBar">false</item>
    <item name="android:windowFullscreen">true</item>
    <item name="android:windowContentOverlay">@null</item>
</style>

    and also mention in your manifest file.

    <activity
   android:name=".activities.FullViewActivity"
   android:theme="@style/Theme.AppCompat.Light.NoActionBar.FullScreen" 
/>
