Q:

Android Interfaces implementation

I'm having an issue with interfaces, i have a class that implements an interface which i expect to fire after a network response of 200. My interface is not called (how do i hook it to my NetworkrequestClass?)
//My class
  public class MyClass extends AnotherClass implements MyDesiredListener{

    private void myMethod(){

       if (!value) {
         NetworkCallClass.specificRequest(); //To call onDesiredLoadedData 
        }
     }

    @Override
    onDesiredLoadedData(){
      //Update Value
     }
   }

   //My inteface in its own file
   interface  MyDesiredListener{
   onDesiredLoadedData();
   }

A:

I'm not sure if I understand you correctly, but if I did here you are:
public class FirstClass implements MyInterface {
    public void method() {
        NetworkCallClass clazz = new NetworkCallClass(this);
        clazz.specificRequest();
    }

    @Override
    public void onDesiredLoadedData() {
        // here you are your callback
    }
}

public class NetworkCallClass {
    MyInterface _callbacks;

    public NetworkCallClass(MyInterface callbacks) {
        _callbacks = callbacks;
    }

    public void specificRequest() {
        // code
        if (networkResponse == 200) {
            _callbacks.onDesiredLoadedData();
        }
    }
}
