## 1、导入依赖 ##

导入方式请参考链接：[https://blog.csdn.net/weixin\_42230348/article/details/103069707][https_blog.csdn.net_weixin_42230348_article_details_103069707]

implementation 'com.squareup.retrofit2:retrofit:2.6.2'
    implementation 'com.squareup.retrofit2:converter-gson:2.6.2'

## 2、安装GsonFormat插件：File——>Settings… ##

## 3、新建network包，在下面定义一个接口（ApiDemoService）和数据数据实体类(Repo),具体实现如下： ##

*（1）接口（ApiDemoService）*

package com.wmc.loginapplication.network;
    
    import java.util.List;
    
    import retrofit2.Call;
    import retrofit2.http.GET;
    import retrofit2.http.Path;
    
    public interface ApiDemoService { 
    
        @GET("users/{user}/repos") //拼接地址：https://api.github.com/users/user/repos
        Call<List<Repo>> listRepos(@Path("user") String user);
    
        @GET("users/{user}/repos")
        Call<List<Repo>> getRepos(@Path("user") String user);
    }

*（2）需要传递的数据实体Repo*：下载接口数据；利用GsonFormat插件转换json数据为实体类

*右击空白——>Generate…*

*再用同样的方式给Repo类添加一个toString（）方法*  
ps:此处用一分钟的操作完成一个小时的工作，感受网络接口的强大吧~~~~~~

3、因为适配器中的实体为Entity,所以这里要自定义一个实体类

package com.wmc.loginapplication;
    
    import android.os.Parcel;
    import android.os.Parcelable;
    
    public class Entity implements Parcelable
    { 
    
        private int count;
    
        private String msg;
    
        public Entity(int count)
        { 
            this.count = count;
        }
    
        public Entity(int count, String msg)
        { 
            this.count = count;
            this.msg = msg;
        }
    
        public Entity(String msg)
        { 
            this.msg = msg;
        }
    
        public int getCount()
        { 
            return count;
        }
    
        public void setCount(int count)
        { 
            this.count = count;
        }
    
        public String getMsg()
        { 
            return msg;
        }
    
        public void setMsg(String msg)
        { 
            this.msg = msg;
        }
    
        @Override
        public int describeContents() {  return 0; }
    
        @Override
        public void writeToParcel(Parcel dest, int flags)
        { 
            dest.writeInt(this.count);
            dest.writeString(this.msg);
        }
    
        protected Entity(Parcel in)
        { 
            this.count = in.readInt();
            this.msg = in.readString();
        }
    
        public static final Parcelable.Creator<Entity> CREATOR = new Parcelable.Creator<Entity>()
        { 
            @Override
            public Entity createFromParcel(Parcel source) { return new Entity(source);}
    
            @Override
            public Entity[] newArray(int size) { return new Entity[size];}
        };
    }

4、主活动相应*RefreshActivity*相应实现：注释得很详细！认真理解。

    import retrofit2.Call;
    import retrofit2.Callback;
    import retrofit2.Response;
    import retrofit2.Retrofit;
    import retrofit2.converter.gson.GsonConverterFactory;

            setContentView(R.layout.activity_refresh);
    
            recyclerView = findViewById(R.id.recyclerView) ;
    
            refreshLayout = findViewById(R.id.refreshLayout);
    
            //设置布局管理器
            recyclerView.setLayoutManager(new LinearLayoutManager(this));
            //设置适配器
            adapter = new RecyclerViewListDemoAdapter(this);
            recyclerView.setAdapter(adapter);
    
            //下拉刷新
            refreshLayout.setRefreshHeader(new ClassicsHeader(this));
            //上拉加载
            refreshLayout.setRefreshFooter(new ClassicsFooter(this));

                }
            });
            //为上拉下载添加事件
            refreshLayout.setOnLoadMoreListener(new OnLoadMoreListener() { 
                @Override
                public void onLoadMore(RefreshLayout refreshlayout) { 
                    initData();
                    refreshlayout.finishLoadMore(2000/*,false*/);//传入false表示加载失败
                }
            });
        }
       
            Retrofit retrofit = new Retrofit.Builder()
                    .baseUrl("https://api.github.com/")
                    .addConverterFactory(GsonConverterFactory.create())//将通过网络地址请求到的json内容添加进来
                    .build();
    
    
            ApiDemoService service = retrofit.create(ApiDemoService.class) ;//反射机制实例化ApiDemoService接口
            Call<List<Repo>> call = service.listRepos("octocat");//实现接口中的方法
    
            call.enqueue(new Callback<List<Repo>>() { 
                @Override
                public void onResponse(Call<List<Repo>> call, Response<List<Repo>> response) { 
                    Log.e("----response---" , response.toString()) ;
    
                    List<Repo> repos = response.body() ;//将网络请求的json数据保存到body
    
                    //遍历body区的数据

                }
            });
        }
    }

5、定义适配器*RecyclerViewListDemoAdapter*实现数据的配置和展示

package com.wmc.loginapplication;
    
    import android.content.Context;
    import android.view.LayoutInflater;
    import android.view.View;
    import android.view.ViewGroup;
    import android.widget.TextView;
    import android.widget.Toast;
    
    import androidx.annotation.NonNull;
    import androidx.recyclerview.widget.RecyclerView;
    
    import java.util.ArrayList;
    import java.util.List;
    
    //自定义适配器
    public class RecyclerViewListDemoAdapter extends RecyclerView.Adapter<RecyclerViewListDemoAdapter.ListViewHolder> { 
        private List<Entity> data;
    
        private  Context context ;
    
        private RecyclerViewActivity.OnItemClickListener onItemClickListener;
    
        public RecyclerViewListDemoAdapter(Context context)
        { 
            this.context = context;
        }
    
        public void setOnItemClickListener(RecyclerViewActivity.OnItemClickListener onItemClickListener)
        { 
            this.onItemClickListener = onItemClickListener;
        }
    
        public RecyclerViewListDemoAdapter(List<Entity> data)
        { 
            this.data = data;
        }
    
    
        public void setData(List<Entity> data)
        { 
            this.data = data;
            // 刷新数据
            notifyDataSetChanged();
        }
        //为相应逻辑添加数据
        public void addData(List<Entity> entities)
        { 
            if (data == null)
            { 
                data = new ArrayList<>();
            }
            this.data.addAll(entities);
            notifyDataSetChanged();
        }
    
        /** *创建一个viewHolder并返回 * @param parent 相当于Item存放的容器 * @param viewType 指定布局文件的类型 * @return 返回viewHolder对象 */
        @NonNull
        @Override
        public ListViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) { 
            //指定对应的布局文件
           View view =  LayoutInflater.from(parent.getContext()).inflate(R.layout.item_list_demo,parent,false);
            return new ListViewHolder(view);
    
        }
    
        /** * 将数据加载到布局文件的控件上 * @param holder 需要绑定数据的viewHolder * @param position 列表数据的下标 */
        @Override
        public void onBindViewHolder(@NonNull RecyclerViewListDemoAdapter.ListViewHolder holder, final int position) { 
            Entity entity = data.get(position);
            holder.textView.setText(entity.getMsg());
            //将绑定的布局设置点击事件
            holder.textView.setOnClickListener(new View.OnClickListener() { 
                @Override
                public void onClick(View v) { 
                   if(onItemClickListener!=null){ 
                        onItemClickListener.itemClick(position,v);
                   }
                }
            });
        }
        /** *返回数据的大小 * @return */
        @Override
        public int getItemCount() { 
            return data == null ? 0 : data.size();
        }
        //为了系统复用控件
        static class ListViewHolder extends RecyclerView.ViewHolder
        { 
            TextView textView;
    
            public ListViewHolder(@NonNull View itemView)
            { 
                super(itemView);
                // 实例化该控件
                textView = itemView.findViewById(R.id.tv_text);
            }
        }
    }

5、主活动布局*activity\_refresh*和数据布局*item\_list\_demo*

<?xml version="1.0" encoding="utf-8"?>
    <com.scwang.smartrefresh.layout.SmartRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/refreshLayout"
        tools:context=".RefreshActivity">
    
    
        <androidx.recyclerview.widget.RecyclerView
    
            android:id="@+id/recyclerView"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:overScrollMode="never"
            android:background="#fff" />
    
    </com.scwang.smartrefresh.layout.SmartRefreshLayout>

<?xml version="1.0" encoding="utf-8"?>
    <androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">
    
        
        <TextView
            android:id="@+id/tv_text"
            android:layout_width="0dp"
            android:lines="5"
            android:layout_height="wrap_content"
            android:gravity="center_horizontal"
            android:padding="30dp"
            android:textSize="18sp"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintHorizontal_bias="0.0"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent"
            tools:text="TextView"
            tools:textColor="@color/colorPrimary"
            tools:textSize="30sp" />
    
        <View
            android:id="@+id/textView7"
            android:layout_width="0dp"
            android:layout_height="2dp"
            android:layout_marginBottom="4dp"
            android:background="#4E0B0B"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toBottomOf="@+id/tv_text" />
    
    
    </androidx.constraintlayout.widget.ConstraintLayout>

OK，代码写完！跑起来看看！  
大功告成~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
