Flattening nested data

http://stackoverflow.com/questions/39258219/firebaserecycleradapter-with-2-childs?noredirect=1#comment65887443_39258219

If I have this Data Structure:

Database:
   X:{
     UserID:{
        UNIQUE_ID_GENERATED_BY_PUSH_METHOD:{
          x:"hello",
          y:"hey there!"
       }
        UNIQUE_ID_2_GENERATED_BY_PUSH_METHOD:{
          x:"what's up?",
          y:"Nothing Much"
       }
   }  
    UserID2:{
        UNIQUE_ID_GENERATED_BY_PUSH_METHOD:{
          x:"bye",
          y:"Have a nice day!"
       }
        UNIQUE_ID_2_GENERATED_BY_PUSH_METHOD:{
          x:"what's up?",
          y:"Nothing Much"
       }
   }  
}

And I'm trying to retrieve x and y into a FireBaseRecyclerAdapter, and it's not possible without making my own huge code. I'd love a feature like this; it'll make things much easier and will trim up my database.

I think it could be what you are looking for: if you index your data, all you have to do is provide it a list of keys to get x and y. See the documentation: https://github.com/SUPERCILEX/FirebaseUI-Android/blob/7e2be3aed73735e3d4e1a318cf268a5c9db67475/database/README.md#using-firebaseui-with-indexed-data

I think you would have to change your data structure to be something like this:

message-keys: {
    uid1: {
        key1: true
        key2: true
    }
    uid2: {
        key1: true
        key2: true
    }
}
messages: {
    key1: {
        x: "bye"
        y: "Have a nice day!"
    }
    key2: {
        x: "what's up?"
        y: "Nothing Much"
    }
}

Then you would create a RecyclerView like so:

new FirebaseRecyclerAdapter<Chat, ChatHolder>(Chat.class, android.R.layout.two_line_list_item, ChatHolder.class, ref.child("message-keys").child(uid), ref.child("messages"))

Hope this helps!

I already did this manually. Thanks anyway
