Query inside for loop in Back4App(Parse)

Question

I am building a social network application using parse which have follow/unfollow feature.

I have two tables: Users and Follow table.

Users table have user related data and Follow table have two fields: followerId and followedId.

I have a list of searched users. So, corresponding to each user i just want to get from query that whether i am following him/her or not. So, how to run query inside a loop?

Any help will be deeply appreciated.

Thanks.

You can achieve this by fetching all user list in loop. When you found all the searched users then you can run the query in the second loop. — Mamta Kaundal

For get follower

ParseQuery query = new ParseQuery("FollowTable");
query.whereEqualTo("followedId", ParseUser.getCurrentUser().getObjectId());
query.findInBackground(new FindCallback() {
    public void done( List<ParseObject> MyList, ParseException e) {

        if (e == null) {
            // Get your follower user list

        }else{
            //error
        }

For get following

ParseQuery query = new ParseQuery("FollowTable");
query.whereEqualTo("followerId", ParseUser.getCurrentUser().getObjectId());
query.findInBackground(new FindCallback() {
    public void done( List<ParseObject> MyList, ParseException e) {

        if (e == null) {
            // Get your following user list

        }else{
            //error
        }

Then after call user list query in ParseUser table and get all the user. Thanks
