Maintain full screen programmatically

Question

I want that screen associated with an activity to be full sized. For this I using this code

    this.requestWindowFeature(Window.FEATURE_NO_TITLE); 
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
    getWindow().getDecorView().setSystemUiVisibility(View.GONE);
    getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LOW_PROFILE);
    if (Build.VERSION.SDK_INT >= 14) {
        getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
    }

    if (Build.VERSION.SDK_INT >= 16) {
        getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN);
    }

However when doing a drag from touch screen appears bar with state (battery state, wifi state, etc). I using Android version 4.2.2 especially. This point I try to show in the picture below. enter image description here

How can that be maintained window to full screen programmatically?

Most likely the problem occured because your code only executed once in onCreate. Try using this in your manifest instead :

<application 
    android:icon="@drawable/icon" 
    android:label="@string/app_name" 
    android:theme="@android:style/Theme.NoTitleBar.Fullscreen">

METHOD: 1 One way is using Theme.Holo.Light.NoActionBar.Fullscreen value in AndroidManifest.xml file. (Use the appropriate theme name whichever you used in your application)

<activity android:name=".MainActivity"
android:label="@string/app_name"
android:theme="@android:style/Theme.Holo.Light.NoActionBar.Fullscreen">
</activity>

METHOD 2: Another way is, do this through code in the activity. In your activity do the following before calling setContentView() function

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

setContentView(R.layout.activity_main);
