Hide Title Bar
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.
Code that hides title bar of activity
The getSupportActionBar() method is used to retrieve the instance of ActionBar class. Calling the hide() method of ActionBar class hides the title bar.
requestWindowFeature(Window.FEATURE_NO_TITLE);//will hide the title
getSupportActionBar().hide(); //hide the title bar
getSupportActionBar().hide(); //hide the title bar
Code that enables full screen mode of activity
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.
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN); //show the activity in full screen
WindowManager.LayoutParams.FLAG_FULLSCREEN); //show the activity in full screen
