Hiding the Title bar and Status bar in Android

We can hide the title and status bars by 2 ways:

1. Using "AndroidManifest.xml" file:

• To hide the title bar use the predefined style
•  android:theme=”@android:style/Theme.NoTitleBar” 
• To hide the status bar use
•   android:theme=”@android:style/Theme.NoTitleBar.Fullscreen”

2. Using code in your activity class:

• @Override

  public void onCreate(Bundle savedInstanceState) {

      super.onCreate(savedInstanceState);

      // hide titlebar of application

      // must be before setting the layout

      requestWindowFeature(Window.FEATURE_NO_TITLE);

      // hide statusbar of Android

      // could also be done later

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

              WindowManager.LayoutParams.FLAG_FULLSCREEN);

      setContentView(R.layout.main);

      text = (EditText) findViewById(R.id.EditText01);

  
  

  }
