Hello at the moment I am trying to update a list in real-time creating a chat app. At the moment I am trying to query with this method ...
private void changeChatLive(String chat) {
listaDeMensajes.clear();
ParseQuery<ParseObject> parseQuery = new ParseQuery("Conversaciones");
// This query can even be more granular (i.e. only refresh if the entry was added by some other user)
// parseQuery.whereNotEqualTo(USER_ID_KEY, ParseUser.getCurrentUser().getObjectId());
//ParseObject chatId = ParseObject.createWithoutData("Chat", chat);
parseQuery.whereEqualTo("ChatId", chatId);
// Connect to Parse server
parseQuery.include("ChatId");
SubscriptionHandling<ParseObject> subscriptionHandling = parseLiveQueryClient.subscribe(parseQuery);
// Listen for CREATE events
subscriptionHandling.handleEvent(SubscriptionHandling.Event.CREATE, new
SubscriptionHandling.HandleEventCallback<ParseObject>() {
@Override
public void onEvent(ParseQuery<ParseObject> query, ParseObject object) {
Handler handler = new Handler(Looper.getMainLooper());
handler.post(new Runnable() {
@Override
public void run() {
mMessageAdapter.notifyDataSetChanged();
mMessageRecycler.scrollToPosition(0);
scroll.fullScroll(FOCUS_DOWN);
}
});
}
});
}
What I need is to update the List<ParseObject> listaDeMensajes as the same way that findInBackground method is going to have List.
The answer to this is as Davi Macedo said. What I did is to custom the query as you like. Then update the list in the run method!.
listaDeMensajes.add(object);
mMessageAdapter.notifyDataSetChanged();
mMessageRecycler.scrollToPosition(0);
