OkHttpUtils简单的网络去解析使用

先添加依赖：

implementation 'com.google.code.gson:gson:2.2.4'
 implementation 'com.zhy:okhttputils:2.0.0'

网络权限：

<uses-permission android:name="android.permission.INTERNET"/>

代码实现：

 public class MainActivity extends AppCompatActivity {

     @Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_main);
         String url="http://www.qubaobei.com/ios/cf/dish_list.php?stage_id=1&limit=20&page=1";
         OkHttpUtils.get()
                 .url(url)//地址
                 .build()
                 //异步
                 .execute(new StringCallback() {
                     @Override
                     public void onError(Request request, Exception e) {
                         //失败
                     }
                     @Override
                     public void onResponse(String response) {
                           //成功
                         Gson gson = new Gson();
                         Bean bean = gson.fromJson(response, Bean.class);
                         List<Bean.DataBean> data = bean.getData();
                         Toast.makeText(MainActivity.this, data.toString(), Toast.LENGTH_SHORT).show();
                     }
                 });
     }
 }
