Question

I want common logout action to all pages in android application.i have common template that contain logout option. but i repeat the logout function to all activity. how to resolve this problem.

Answer 1

The simplest thing would be to extend a common Activity, as someone else suggested. You are able to extends only from one class, that’s why you would do something like this:

public class CommonActivity extends Activity {
     // Here you implement log out methods
}

public class ParticularActivity extends CommonActivity {
    // Here you put your particular class variables and methods
}

This way, you have the logout functionality in every activity, all you have to do is extends the common one.
