Full Screen Theme for AppCompat

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" />

Based on the answer by @nebyan, I found that the action bar is still not hiding.

The following code works for me:

<style name="AppFullScreenTheme" parent="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 of course dont forgot to edit your AndroidManifest file.

<activity    android:name="YOUR_ACTIVITY_NAME"    android:theme="@style/AppFullScreenTheme" />

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

Using the above xml in style.xml, you will be able to hide the title as well as action bar.
