Firebase Add Callback when OnCompleteListener finished [duplicate]

How to return a DocumentSnapShot as a result of a method?

Wait until Firestore data is retrieved to launch an activity
1 answer
I am working on a project using Firebase and I have some issue concerning the OnCompleteListener function.
I want put integer inside a List. These integers are corresponding to number of documents inside a collection.
I have made inside my activity a method called getListWorkmatesJoining().
This method is using a list of "result".
My method :
private void getListWorkmatesJoining(){
for (int i=0 ; i<restaurant_list.size(); i++){
RestaurantHelper.getWorkmatesJoining(restaurant_list.get(i).getPlaceId(), DateUtility.getDateTime())
.addOnCompleteListener(new OnCompleteListener<QuerySnapshot>() {
@Override
public void onComplete(@NonNull Task<QuerySnapshot> task) {
if (task.isSuccessful()) {
if (task.getResult().getDocuments().isEmpty()) {
workmates_list.add(0);
} else {
workmates_list.add(task.getResult().getDocuments().size());
}
}
}
});
}
}
I am adding to my workmates_list an integer. This integer is 0 if the number of document is 0 or the number of document.
How am I able to launch another method when this one is completely finished ?
Is there a callback or something ?
Thanks for your help.

Thanks. The thing which is not that easy in my case is that I am making a loop with multiple addOnCompleteListener. To be sure that one is one it is easy but all of them it is not the same right ?
