Answer 1

Do feature before onCreate

protected void onCreate(Bundle savedInstanceState) {
        // requestWindowFeature(Window.FEATURE_NO_TITLE);

  getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);


        super.onCreate(savedInstanceState);



            // Hide the Title bar of this activity screen


        this.supportRequestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.activity_simple);

Set the window flags before calling super.onCreate():

protected void onCreate(Bundle savedInstanceState) {
        getWindow()...
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_simple);
}

Once try as follows

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

        // Hide the Title bar of this activity screen
    this.supportRequestWindowFeature(Window.FEATURE_NO_TITLE);

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_simple);

hope this will helps you.

In your AndroidManifest.xml

If you are using AppCompat

add one attribute in the activity tag to hide ActionBar

android:theme="@style/Theme.AppCompat.NoActionBar"
