How to create Android application without ActionBar using new theme in API9?

Question

I need to create application wihtout actionbar. I will try to explain how I create application(maybe I am missing some steps).

1.I am intentionally not choosing "Holo Light with Dark Action Bar" option. I thought this make application without action bar. 2.Leaving next page as default: 3.Leaving next page as default: 4.On the next page, it becomes interesting. Blank Activity's description says that it creates a new blank activity an action bar. On Empty Activity's description: Creates a new empty activity. So I choose Empty activity

5.Leaving next page as default.

Result:As usually, application was created with ActionBar.

Tried this solution:getActionBar().hide();. In this solution, ActionBar is hiden after some milliseconds.

Tried to use android:theme="@android:style/Theme.NoTitleBar" in AndroidManifest.xml->application tag. But in this solution, application uses old theme.

My question: how to create Android application without ActionBar using new theme and leaving StatusBar enabled?

PS. I remember, about one year ago, in Eclipse, applications were created without ActionBar. Then we added it manually

Answer 1

Put this right after super.onCreate(savedInstanceState); in the onCreate method of your activity(s):

this.requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

Make sure you put this BEFORE this.setContentView(R.layout.activity_example); to avoid crashes

Answer 2

When your project is started you can use public activity extends Activity instead of using ActionBarActivity this will also remove the action bar or there is another way

    <android:theme="@android:style/Theme.NoTitleBar">

Refer this code and change as per your requirement:

Update :

styles.xml :

 <style name="FullscreenTheme" parent="android:Theme.Holo">
    <item name="android:windowActionBar">false</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:actionBarStyle">@style/FullscreenActionBarStyle</item>
    <item name="android:windowActionBarOverlay">true</item>
    <item name="android:windowBackground">@null</item>
    <item name="metaButtonBarStyle">?android:attr/buttonBarStyle</item>
    <item name="metaButtonBarButtonStyle">?android:attr/buttonBarButtonStyle</item>
</style>

<style name="FullscreenActionBarStyle" parent="android:Widget.Holo.ActionBar">
    <item name="android:background">@color/black_overlay</item>
</style>

These will remove actionbar and keeps your theme as it is .

Note : Here i have tested using Theme.Holo . you can use yours.

AndroidManifest.xml

  <activity
        android:name=".GridViewExample"
        android:theme="@style/FullscreenTheme" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

It gives you activity without ActionBar. Hope this solves your problem.

You can do it programatically:

public class ActivityName extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // remove title
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.main);
    }
}

Or you can do it via your AndroidManifest.xml file:

<activity android:name=".ActivityName"
    android:label="@string/app_name"
    android:theme="@android:style/Theme.NoTitleBar.Fullscreen"/>

EDIT :

If your app uses any other theme use corresponding theme name E.g. For White theme @android:style/Theme.Holo.Light.NoActionBar.Fullscreen
