Full Screen Theme for AppCompat

Question

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();

You can follow below step:-

AndoridMenifest.xml

<activity
            android:name=".ui.FullImageActivity"
            android:label="@string/title_activity_main"
            android:screenOrientation="landscape"
            android:theme="@style/DialogTheme">
        </activity>

Style.xml

<style name="DialogTheme" parent="android:Theme.Dialog">

    <item name="android:layout_width">fill_parent</item>
    <item name="android:layout_height">fill_parent</item>

   <!-- No backgrounds, titles or window float -->
    <item name="android:windowNoTitle">false</item>
    <item name="android:windowFullscreen">true</item>
    <item name="android:windowIsFloating">false</item>
</style>

FullImageActivity.java

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setLayout(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
    setContentView(R.layout.image_view);
     }

I hope it will help..Thanks!!

<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.

Your "workaround" (hiding the actionBar yourself) is the normal way. But google recommands to always hide the ActionBar when the TitleBar is hidden. Have a look here: https://developer.android.com/training/system-ui/status.html

Answer 4

It should be parent="@style/Theme.AppCompat.Light.NoActionBar"

<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>

Answer 5

<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>

Issues arise among before and after versions of Android 4.0 (API level 14)..

from here https://developer.android.com/training/system-ui/status.html I created my own solution..

@SuppressLint("NewApi")
@Override
protected void onResume()
{
    super.onResume();

    if (Build.VERSION.SDK_INT < 16)
    {
        // Hide the status bar
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
        // Hide the action bar
        getSupportActionBar().hide();
    }
    else
    {
        // Hide the status bar
        getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN);
        / Hide the action bar
        getActionBar().hide();
    }
}

I write this code in onResume() method because if you exit from your app and then you reopen it, the action bar remains active! (and so this fix the problem)

I hope it was helpful ;)
