RecyclerView 初学遇到的问题?报错

写RecyclerView的adapter时报错，不知如何解决。

新手刚学用RecyclerView，在定义adapter类时就报错，错误见图。代码时参考书上的代码，并且也在网上搜索，看不出代码错在哪里？build通不过！ 

package com.example.recyclerviewapp;

import android.support.v7.widget.RecyclerView;
import android.support.v7.widget.RecyclerView.Adapter;
import android.text.Layout;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;

import java.util.List;

    private List<Fruit> mFruitList;
    static class myViewHolder extends RecyclerView.ViewHolder{

    ImageView fruitImage;
    TextView fruitName;
        public  myViewHolder(View view) {
        super(view);
        fruitImage = (ImageView) view.findViewById(R.id.fruit_image);
        fruitName = (TextView) view.findViewById(R.id.fruit_name);
       }
    }
    public FruitAdapter(List<Fruit>fruitList){
        mFruitList=fruitList;
    }

    @Override
    public myViewHolder OnCreateViewHolder(ViewGroup parent,int viewType){
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.fruit_item,parent,false);
        myViewHolder holder=new myViewHolder(view);
        return holder;
    }
    @Override
    public void onBindViewHolder(myViewHolder holder,int position){
        Fruit fruit=mFruitList.get(position);
        holder.fruitImage.setImageResource(fruit.getImageId());
        holder.fruitName.setText(fruit.getName());
    }
    @Override
    public int getItemCount(){
        return mFruitList.size();
    }
}
