Hide Title Bar Example

Now, we will 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 have to 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);  
}

Activity class

package com.fastread.hidetitle;  
import android.os.Bundle;

import android.view.Menu;  
import android.view.Window;  
import android.view.WindowManager; 
public class MainActivity extends Activity {

        super.onCreate(savedInstanceState);  
        requestWindowFeature(Window.FEATURE_NO_TITLE);  
      /*this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
                  WindowManager.LayoutParams.FLAG_FULLSCREEN);//int flag, int mask 
      */  
        setContentView(R.layout.activity_main);
