How to hide Title Bar in Android

In Android we can hide the title bar and run our app in full screeb view.

To Do this we will use  requestWindowFeature(Window.FEATURE_NO_TITLE)


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.

1.  @Override  
2.     protected void onCreate(Bundle savedInstanceState) {  
3.         super.onCreate(savedInstanceState);  
4.           
5.         requestWindowFeature(Window.FEATURE_NO_TITLE);//will hide the title not the title bar  
6.           
7.         setContentView(R.layout.activity_main);  
8.         
9.     }  
10. }  

he 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.

1. equestWindowFeature(Window.FEATURE_NO_TITLE);  
2.     //code that displays the content in full screen mode  
3.     this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,  
4.                 WindowManager.LayoutParams.FLAG_FULLSCREEN);//int flag, int mask  
5.       
6.     setContentView(R.layout.activity_main);  
7.
