Our builder is ready...How do I create the Alert DIalog variable and return it?

I am really stuck my code is attached!

AlertDialogFragment.java
import android.content.Context;
import android.os.Bundle;

public class AlertDialogFragment extends DialogFragment {
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        Context context = getActivity();

 AlertDialog.Builder builder = new AlertDialog.Builder(context);
          builder.setTitle("Sorry!");
          builder.setMessage("Try again!");
          builder.setPositiveButton("OK", null);

      AlertDialog create = new AlertDialog();

        return create;
    }
}
MovieActivity.java
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import java.io.IOException;

public class MovieActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_movie);

        // Get some movie information!
        String apiUrl = "http://api.rottentomatoes.com/api/public/v1.0/movies.json?apikey=xyz&q=hobbit";
        OkHttpClient client = new OkHttpClient();
        Request request = new Request.Builder()
                .url(apiUrl)
                .build();

        Call call = client.newCall(request);
        call.enqueue(new Callback() {
            @Override
            public void onFailure(Request request, IOException e) {

            }

            @Override
            public void onResponse(Response response) throws IOException { }
        });


    }



    }

}

HI Andreas

I think in your AlertDialogFragment you are returning a new object which has nothing applied when you should be returning the object you created initially. I have edited the code below.

import android.content.Context;
import android.os.Bundle;

public class AlertDialogFragment extends DialogFragment {
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        Context context = getActivity();

 AlertDialog.Builder builder = new AlertDialog.Builder(context);
          builder.setTitle("Sorry!");
          builder.setMessage("Try again!");
          builder.setPositiveButton("OK", null);

      AlertDialog create = builder.create();

       return create;
    }
}

Hope this helps

Daniel
