I am extending my class from GLScreen class. But I need to call the Activity class methods such as getString and getPreferences. How can I call these methods? Because I can extend only from one class.

You have to pass a reference of your Activity to your class to able to call getPreferences()/getString(). You can do this via constructor/setter.

Something like this:

public YOURCLASS extends GLScreen {

     Activity mActivity;

     public YOURCLASS(Activity activity){
         mActivity = activity;
     }

     ...

     // call this in a method
     mActivity.getString(...);
}

In your Activity call it like this:

YOURCLASS foo = new YOURCLASS(this);

  • @user3634684 Then ask a question with all your details! What you want to achieve and what code you already have. – Steve Benett May 22 '14 at 07:04
