How do you now find the ParseRoles associated with the current ParseUser?

Question

I want to fill in ListViewwith the help of Arrayor ArrayListother ParseRolecurrent one associated with it ParseUser. I suppose this requires some kind of query for the current user, however I'm just not sure how you return the roles and also return them to Arrayor ArrayListwith which I could fill in ListView, I know that you can use the current user:

ParseUser.getCurrentUser();

However, I cannot find from there how you install the roles that have been allocated by the User.

EDIT:

I also tried experimenting with this:

ParseQuery<ParseRole> query = ParseRole.getQuery();
query.whereEqualTo("users", ParseUser.getCurrentUser().getObjectId());
query.findInBackground(new FindCallback<ParseRole>() {
   @Override
   public void done(List<ParseRole> objects, ParseException e) {
      if(e == null) {
         Toast.makeText(getApplicationContext(), objects.size() + "", Toast.LENGTH_SHORT).show();
      } else {
         Toast.makeText(getApplicationContext(), "ERROR", Toast.LENGTH_SHORT).show();
      }
   }                      
});

Android

ParseQuery<ParseRole> query = ParseRole.getQuery();
query.whereEqualTo('users', ParseUser.getCurrentUser());
query.findInBackground(new FindCallback<ParseRole>() {
    public void done(List<ParseRole> roles, ParseException e) {
        // do your thing with the roles list
    }
});

iOS Objective-C

PFQuery *query = [PFRole query];
[query whereKey:@"users" equalTo:[PFUser currentUser]];
[query findObjectsInBackgroundWithBlock:^(NSArray *roles, NSError *error) {
  if (!error) {
    // Do something with the found roles
  }
}];

iOS Swift

var query = PFRole.query();
query.whereKey('users', equalTo:PFUser.currentUser());
query.findObjectsInBackgroundWithBlock {
  (roles: [PFObject]!, error:NSError!) -> Void in
  if error == nil {
    // do your thing with the roles
  }
}

JavaScript

var query = new Parse.Query(Parse.Role);
query.equalTo('users', Parse.User.current());
query.find().then(function(roles) {
  // do your thing with the roles array
});

Answer 3

ParseRole myroles= (ParseRole) new ParseQuery("Role").whereEqualTo("name", "AppName-"+currentuserid).getFirst();


Here  "name" -----------Column in Role Table

      "AppName" --------eg: "MyApp-23"   in your _User table



I think this helps...
