How to query a pointer in a ParseObject class?

Question

Hi i made ParseObject which contains a field called Usuario which is a pointer to _User(ParseUser class)

ive been trying to query for this value with no success...

private void queryConversaciones(){
    ParseQuery<ParseObject> query = ParseQuery.getQuery("Conversaciones");
    query.findInBackground(new FindCallback<ParseObject>() {
        @Override
        public void done(List<ParseObject> objects, ParseException e) {
            for (ParseObject obj:objects
                 ) {
                mensaje=obj.getString("Mensaje");
                enviaMensaje= (ParseUser) obj.get("Usuario");

               // mMessageList.add(obj);

            }
        }
    });
}

Just add query.include("key"); to retrieve the pointer object.

So your complete query should look like this:

private void queryConversaciones(){
    ParseQuery<ParseObject> query = ParseQuery.getQuery("Conversaciones");

    // Include data at pointer
    query.include("Usuario");

    query.findInBackground(new FindCallback<ParseObject>() {
        @Override
        public void done(List<ParseObject> objects, ParseException e) {
            for (ParseObject obj:objects
                 ) {
                mensaje=obj.getString("Mensaje");
                enviaMensaje= (ParseUser) obj.get("Usuario");

               // mMessageList.add(obj);

            }
        }
    });
}

Now you should be able to access all the data stored in the _User object.

I got all this information from the relational queries section in the Parse Android guide.
