方法不会覆盖populateViewHolder

Question

onStart函数：

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

        mAuth.addAuthStateListener(mAuthListener);

        FirebaseRecyclerAdapter<Blog, BlogViewHolder> firebaseRecyclerAdapter = new FirebaseRecyclerAdapter<Blog, BlogViewHolder>(
                Blog.class,
                R.layout.blog_row,
                BlogViewHolder.class,
                mQueryCurrentUser
        ) {
            @Override
            public BlogViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
                return null;
            }
            @Override
            protected void onBindViewHolder(@NonNull BlogViewHolder holder, int position, @NonNull Blog model) {

            }
            @Override
            protected void populateViewHolder(BlogViewHolder viewHolder, Blog model, int position) 

方法不会在启动函数中重写其父类中的方法（第三次重写）

import android.content.Context;
import android.content.Intent;
import android.support.annotation.NonNull;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
