3.主布局文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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:orientation="vertical"
    tools:context="com.example.retrofitdemo0413.MainActivity">

    <TextView
        android:id="@+id/text_show"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Hello World!"/>
    <Button
        android:id="@+id/btn_dianji"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Retrofit？路径请求数据"/>
    <Button
        android:id="@+id/btn_dianji2"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Retrofit/路径请求数据"/>

</LinearLayout>

4.定义接口

package com.example.retrofitdemo0413;

import java.util.List;
import java.util.Map;
import retrofit2.http.GET;
import retrofit2.Call;
import retrofit2.http.Path;
import retrofit2.http.QueryMap;

//1.声明一个接口
    public interface ApiService {
        //2.声明一个接口对象 路径"？"
    @GET("user/getUserInfo")
    Call<MessageBean<InfoBean>> getInfo(@QueryMap Map<String,String> params);

    //3.声明一个借口对象 路径“/”
    @GET("search/query/listview/category/Android/count/{count}/page/{page}")
    Call<NewsBean<List<News>>> getNews(@Path("count") String count,@Path("page") String page);
}

5.Acivity的实现

package com.example.retrofitdemo0413;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import butterknife.BindView;
import butterknife.ButterKnife;
import butterknife.OnClick;
import retrofit2.Call;
import retrofit2.Callback;
import retrofit2.Response;
import retrofit2.Retrofit;
import retrofit2.converter.gson.GsonConverterFactory;

public class MainActivity extends AppCompatActivity {

    @BindView(R.id.text_show)
    TextView textShow;
    @BindView(R.id.btn_dianji)
    Button btn_dj;
    @BindView(R.id.btn_dianji2)
    Button btn_Dianji2;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        ButterKnife.bind(this);
    }
    
    //点击事件
    @OnClick({R.id.btn_dianji, R.id.btn_dianji2})
    public void onViewClicked(View view) {
        switch (view.getId()) {
            case R.id.btn_dianji:

                Retrofit retrofit = new Retrofit.Builder()
                        .baseUrl("https://www.zhaoapi.cn/user/")
                        //添加Gson自动解析
                        .addConverterFactory(GsonConverterFactory.create())
                        .build();
                ApiService service = retrofit.create(ApiService.class);

                Map<String, String> params = new HashMap<>();
                params.put("uid", "71");
                Call<MessageBean<InfoBean>> call = service.getInfo(params);

                //进行异步操作
                call.enqueue(new Callback<MessageBean<InfoBean>>() {
                    //成功
                    @Override
                    public void onResponse(Call<MessageBean<InfoBean>> call, Response<MessageBean<InfoBean>> response) {
                        Log.e("======+", response.body().getMsg());
                        Log.e("线程名称", Thread.currentThread().getId() + Thread.currentThread().getName());
                        textShow.setText("晚安");
                    }

                    //失败
                    @Override
                    public void onFailure(Call<MessageBean<InfoBean>> call, Throwable t) {
                        Log.e("-----", t.getMessage());
                    }
                });
                break;
            case R.id.btn_dianji2:

                Retrofit retrofit2 = new Retrofit.Builder()
                        .baseUrl("http://gank.io/api/")
                        //添加Gson自动解析
                        .addConverterFactory(GsonConverterFactory.create())
                        .build();
                 ApiService service2 = retrofit2.create(ApiService.class);
                Call<NewsBean<List<News>>> call1 = service2.getNews("10","1");
                call1.enqueue(new Callback<NewsBean<List<News>>>() {
                    @Override
                    public void onResponse(Call<NewsBean<List<News>>> call, Response<NewsBean<List<News>>> response) {
                        List<News> results = response.body().getResults();
                        if(results!=null){
                            Log.i("新闻条目的数量：", String.valueOf(results.size()));
                        }else{
                            Log.i("新闻条目的数量:","0");
                        }
                    }

                    @Override
                    public void onFailure(Call<NewsBean<List<News>>> call, Throwable t) {
                        Log.i("++++：", t.getMessage());

                    }
                });
                break;
        }
    }
}

6.第一条接口的外层泛型封装类

package com.example.retrofitdemo0413;

public class MessageBean<T> {

    private String msg;
    private String code;
    private T data;

    public String getMsg() {
        return msg;
    }

    public void setMsg(String msg) {
        this.msg = msg;
    }

    public String getCode() {
        return code;
    }

    public void setCode(String code) {
        this.code = code;
    }

    public T getData() {
        return data;
    }

    public void setData(T data) {
