Android Hide Title Bar Example

In this example, we are going to explain how to hide the title bar and how to display content in full screen mode.

The requestWindowFeature(Window.FEATURE_NO_TITLE) method of Activity must be called to hide the title. But, it must be coded before the setContentView method.

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        
        requestWindowFeature(Window.FEATURE_NO_TITLE);//will hide the title not the title bar
        
        setContentView(R.layout.activity_main);
      
    }
}

The setFlags() method of Window class is used to display content in full screen mode. You need to pass the WindowManager.LayoutParams.FLAG_FULLSCREEN constant in the setFlags method.

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        //code that displays the content in full screen mode
        this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                    WindowManager.LayoutParams.FLAG_FULLSCREEN);//int flag, int mask
        
        setContentView(R.layout.activity_main);
      
    }
}
