Parse.com android view request result

I have a question, this may sound like a silly question, but I really don't know how to answer.

In parse.com, after the request completes, how can I display the result

For example this

ParseQuery<ParseObject> gameQuery = ParseQuery.getQuery("Game");
gameQuery.whereEqualTo("createdBy", ParseUser.getCurrentUser());

I want to set the result of a query to a text view in my application textview.setText(??)

:;

Thank you in advance:)

Edit:

and this is the code i am using

public class Adapter extends ParseQueryAdapter<ParseObject> {
//MediaPlayer mediaPlayer;

public Adapter(Context context) {

    super(context, new ParseQueryAdapter.QueryFactory<ParseObject>() {
        public ParseQuery create() {
            ParseQuery query = new ParseQuery("Game");
            return query;
        }
    });
}

// Customize the layout by overriding getItemView
@Override
public View getItemView(final ParseObject object, View v, ViewGroup parent) {

    if (v == null) {
        v = View.inflate(getContext(), R.layout.list_item, null);
    }

    super.getItemView(object, v, parent);

    // I'm getting Images from Game class
    ParseImageView audioImage = (ParseImageView) v.findViewById(R.id.list_image);
    ParseFile imageFile = object.getParseFile("img");
    if (imageFile != null) {
        audioImage.setParseFile(imageFile);
        audioImage.loadInBackground();
    }//end if


    //retrieving Titles from Game Class
    TextView titleTextView = (TextView) v.findViewById(R.id.list_title);
    titleTextView.setText(object.getString("title"));


    //Now I want to retrieve name from User Class :(
    // the code is crashing my app
    //?????????????????????????????????????????????????

    ParseQuery<ParseObject> userQuery = ParseQuery.getQuery("Game");
    userQuery.whereEqualTo("createdBy", ParseUser.getCurrentUser());
    userQuery.findInBackground(new FindCallback<ParseObject>() {
        @Override
        public void done(List<ParseObject> list, com.parse.ParseException e) {

            if (e == null) {
                ParseObject userName = list.get(0); // Gets first object

                // You can get fields using the get() method
                ParseUser user = (ParseUser) userName.get("createdBy");

                // There are data specific methods as well
                String firstName = user.getString("name");

                nameTextView.setText(firstName);
            } else {
                Log.d("score", "Error: " + e.getMessage());
            }
        }

    });





    return v;
}//end getItem View

}//end custom Adapator

ParseQuery<ParseObject> gameQuery = ParseQuery.getQuery("Game");
gameQuery.whereEqualTo("createdBy", ParseUser.getCurrentUser());
gameQuery.findInBackground(new FindCallback<ParseObject>() {
    public void done(List<ParseObject> gameList, ParseException e) {
        if (e == null) {
            ParseObject game = gameList.get(0); // Gets first object

            // You can get fields using the get() method
            ParseUser user = game.get("createdBy");

            // There are data specific methods as well
            String firstName = user.getString("userFirstName");

            textview.setText(firstName);
        } else {
            Log.d("score", "Error: " + e.getMessage());
        }
    }
});

Above is an example. See the documentation for ParseObject

all methods get*()

to get data from an object.

Some of them are: get()

, getString()

, getBoolean

, etc.

UPDATE:



First you will need to specify your query to fetch pointer data (Parse does not include pointer data for queries by default). This is why your application crashes. So update your query to this:

ParseQuery<ParseObject> userQuery = ParseQuery.getQuery("Game");
userQuery.whereEqualTo("createdBy", ParseUser.getCurrentUser());
userQuery.include("createdBy");

UPDATE 2:

public class Adapter extends ParseQueryAdapter<ParseObject> {
    //MediaPlayer mediaPlayer;

    public Adapter(Context context) {

        super(context, new ParseQueryAdapter.QueryFactory<ParseObject>() {
            public ParseQuery create() {
                ParseQuery query = new ParseQuery("Game");
                userQuery.whereEqualTo("createdBy", ParseUser.getCurrentUser());
                query.include("createdBy");
                return query;
            }
        });
    }

    // Customize the layout by overriding getItemView
    @Override
    public View getItemView(final ParseObject object, View v, ViewGroup parent) {

        if (v == null) {
            v = View.inflate(getContext(), R.layout.list_item, null);
        }

        super.getItemView(object, v, parent);

        // I'm getting Images from Game class
        ParseImageView audioImage = (ParseImageView) v.findViewById(R.id.list_image);
        ParseFile imageFile = object.getParseFile("img");
        if (imageFile != null) {
            audioImage.setParseFile(imageFile);
            audioImage.loadInBackground();
        }//end if


        //retrieving Titles from Game Class
        TextView titleTextView = (TextView) v.findViewById(R.id.list_title);
        titleTextView.setText(object.getString("title"));


        //Now I want to retrieve name from User Class :(
        // the code is crashing my app
        //?????????????????????????????????????????????????

        // You can get fields using the get() method
        ParseUser user = (ParseUser) object.get("createdBy");

        // There are data specific methods as well
        String firstName = user.getString("name");

        nameTextView.setText(firstName);

        return v;
    }//end getItem View

}//end custom Adapator
