How to program for the new Recycler View

0

I was following a programmer's guidelines, but I already have 1 year of it. How is the new methodology? It's a chat app and I'd like to call in my activity the profile picture of the person, along with her name and status ....

Follow the code below ...

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.support.v7.widget.Toolbar;
import android.view.View;
import android.widget.TextView;

import com.firebase.ui.database.FirebaseRecyclerAdapter;
import com.google.firebase.database.DatabaseReference;
import com.google.firebase.database.FirebaseDatabase;

public class UsersActivity extends AppCompatActivity {

    private Toolbar mToolbar;
    private RecyclerView mUsersList;

    private DatabaseReference mUserDatabase;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_users);

        // Toolbar
        mToolbar = (Toolbar) findViewById(R.id.users_appBar);
        setSupportActionBar(mToolbar);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setTitle("Contatos");


        mUserDatabase = FirebaseDatabase.getInstance().getReference().child("Users");

        mUsersList = (RecyclerView) findViewById(R.id.users_list);
        mUsersList.setHasFixedSize(true);
        mUsersList.setLayoutManager(new LinearLayoutManager(this));

    }

    @Override
    protected void onStart() {
        super.onStart();

        FirebaseRecyclerAdapter<Users, UsersViewHolder> firebaseRecyclerAdapter = new FirebaseRecyclerAdapter<Users, UsersViewHolder>(
                Users.class,
                Users.class,
                R.layout.users_single_layout,
                UsersViewHolder.class,
                mUserDatabase

        ) {
            @Override
            protected void populateViewHolder(UsersViewHolder usersViewHolder,Users users, int i) {

                usersViewHolder.setName(users.getName());


            }
        };


        mUsersList.setAdapter(firebaseRecyclerAdapter);
    }


    public class UsersViewHolder extends RecyclerView.ViewHolder {

        View mView;

        public UsersViewHolder(View itemView) {
            super(itemView);

            mView = itemView;
        }

        public void setName(String name){

            TextView userNameView = (TextView) mView.findViewById(R.id.settings_name);
            userNameView.setText(name);

        }

    }
}
