I want to clear the value of the shared preference

I have stored the username and the password in the sharedpreference. And I am displaying the username in every activity like Welcome "Username". But at the time of logout I have put one checkbox in the dialog box.If the check box is checked the sharedpreference value should be clear. So I don't know how to do it.Please help me out of it. Thank you.

Your_sharedprefrence_name.commit();

  2. 2nd Method

     Your_sharedprefrence_name.clear().commit();

  3. 3rd Method(When u want to clear the arraylist of sharedprefrence put it in loop)

    Your_sharedprefrence_name.remove(String.valueOf(i)).clear().commit();

SharedPreferences settings = getSharedPreferences("MyPreferences", 0);
if (settings.contains("mykey")) {    
    SharedPreferences.Editor editor = settings.edit();
    editor.remove("mykey");
    editor.apply();    
}

The method to clear the sharedpreferences is this

http://developer.android.com/reference/android/content/SharedPreferences.Editor.html#clear()

With this you dont delete the xml

Editor.clear();

Editor.commit();

You have to use remove method which is simple and described here. The only parameter is the Key you have used to save this preference.
