How to disable title bar in portrait / Landscape mode

This post talks about how to hide/show title bar in portrait and landscape.

There are scenarios where we might want to display a title bar in portrait and not in landscape due to space limitations in landscape.

How do we do this ??

- Every time a screen is rotated from landscape to portrait or vice versa, the activity is destroyed and created again.

- In onCreate(), check the screen sizes and decide it is in portrait or Landscape.

- Based on the mode, set the Window attribute Window.FEATURE_NO_TITLE using requestWindowFeature() api.

Note that requestWindowFeature() api needs to be called before setting the content view.

   onCreate()
   {
   setTitleBar();  --> Call to decide to set whether title bar or not.
   setContentView(R.layout.main);
   }

  public void setTitleBar()
   {
  Display display = ((WindowManager)mContext.getSystemService(mContext.WINDOW_SERVICE)).getDefaultDisplay();  
    
  int width = display.getWidth();  
  int height = display.getHeight(); 
  
  
  if(width > height)
  {
                           /* In Landscape */
      requestWindowFeature(Window.FEATURE_NO_TITLE); 
  }
  
   }
