Accessing Volley Response With Callback Interfaces

I m trying to extract android volley response to a member variable of the same class. I used callback interfaces to perform this task : public void getData(MyCustomListener customL

Solution 1:

Ok. In reference to the comment above, I am writing some steps you should try since I do not have a clear picture of what might be wrong.

Let's start with your MyCustomListener. I do not know why are you setting the response type to Object. If it is to use this in multiple requests then you can modify it like the following with generics

publicinterfaceMyCustomListener<T> {

    publicvoidonResponse(T response);

    publicvoidonError(String error_response);
}

then use it like this when a callback is needed

getData(newMyCustomListener<List<CompleteCartProItem>>() {
      @OverridepublicvoidonResponse(List<CompleteCartProItem> response) {
        completeCartProItems.addAll(response);
      }

     @OverridepublicvoidonError(String error_response) {
         //handle error
       }
});

Also make sure you are not re-initialising completeCartProItems elsewhere after the callback.

Not really sure if the following will fix your issue but make sure that your callback is executed in the UI thread, too.
