Fullscreen Activity in Android?

Question

How do I make an activity full screen? I mean without the notification bar. Any ideas?

Answer 1

If your using AppCompat and ActionBarActivity, then use this

getSupportActionBar().hide();

Answer 2

With kotlin this is the way I did:

class LoginActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_login)
        window.decorView.systemUiVisibility =
                View.SYSTEM_UI_FLAG_LAYOUT_STABLE or
                View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN or
                View.SYSTEM_UI_FLAG_FULLSCREEN

    }
}

Immersive Mode

The immersive mode is intended for apps in which the user will be heavily interacting with the screen. Examples are games, viewing images in a gallery, or reading paginated content, like a book or slides in a presentation. For this, just add this lines:

View.SYSTEM_UI_FLAG_HIDE_NAVIGATION or
View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION

Sticky immersive

In the regular immersive mode, any time a user swipes from an edge, the system takes care of revealing the system bars—your app won't even be aware that the gesture occurred. So if the user might actually need to swipe from the edge of the screen as part of the primary app experience—such as when playing a game that requires lots of swiping or using a drawing app—you should instead enable the "sticky" immersive mode.

View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY

In case your using the keyboard, sometimes happens that StatusBar shows when keyboard shows up. In that case I usually add this to my style xml

styles.xml

<style name="FullScreen" parent="AppTheme">
    <item name="android:windowFullscreen">true</item>
</style>

And also this line to my manifest

<activity
        android:name=".ui.login.LoginActivity"
        android:label="@string/title_activity_login"
        android:theme="@style/FullScreen">

Answer 3

In AndroidManifest.xml file:

<activity
    android:name=".Launch"
    android:label="@string/app_name"
    android:theme="@android:style/Theme.NoTitleBar.Fullscreen" > <!-- This line is important -->

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

Or in Java code:

protected void onCreate(Bundle savedInstanceState){
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
}

Answer 4

It worked for me.

if (Build.VERSION.SDK_INT < 16) {
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
    } else {
        View decorView = getWindow().getDecorView();
        int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
        decorView.setSystemUiVisibility(uiOptions);
    }

Answer 5

Using Android Studio (current version is 2.2.2 at moment) is very easy to add a fullscreen activity.

See the steps:

1. Right click on your java main package > Select “New” > Select “Activity” > Then, click on “Fullscreen Activity”.

2. Customize the activity (“Activity Name”, “Layout Name” and so on) and click “finish”.

Done!

Now you have a fullscreen activity made easily (see the java class and the activity layout to know how the things works)!

Answer 6

Inside styles.xml...

<!-- No action bar -->
<style name="NoActonBar" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Theme customization. -->
    <item name="colorPrimary">#000</item>
    <item name="colorPrimaryDark">#444</item>
    <item name="colorAccent">#999</item>
    <item name="android:windowFullscreen">true</item>
</style>

This worked for me. Hope it'll help you.
