I make an app where the logged in user can see the other users from Firestore database ( they are in a recyclerView ) . Each item of the recycler view has a button called "Add friend". I want to send a friend request to that specific user when I click that button.
I have a tab called "Pending requests" where the logged in can see the received friend requests.
I am using an adapter for recycler view. In MyAdapter.java I have this :
public class myViewHolder extends RecyclerView.ViewHolder{
TextView usernamerecycle;
Button addbutton;
View rootview;
private FirebaseAuth mAuth;
FirebaseFirestore firestore;
public myViewHolder(@NonNull View itemView) {
super(itemView);
rootview = itemView;
usernamerecycle = itemView.findViewById(R.id.usernamerecycler);
addbutton = itemView.findViewById(R.id.addfriendbutton);
addbutton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Log.d(TAG, "item clicked: " + getAdapterPosition() + "user= " + userArrayList.get(getAdapterPosition()).username );
}
});
}
}
My question is : When I send a friend request to a particular user which should be the steps? Should I create a collection called "Requests" for each user and for example when I click the button for "ralu" then a new Request to appear in ralu's "Requests" collection ? After that to display all the pending requests from there in "Pending requests" tab of that user ? Do you have an example or something of how should I do this? How can I put data in another user collection ( other than the logged in user )? Please !!!
