#Android #Xutils网络请求

首先在 build.gradle 里导入：

compile 'org.xutils:xutils:3.5.0'依赖库。

然后创建App类继承Application：

public class App extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        x.Ext.init(this);
        x.Ext.setDebug(BuildConfig.DEBUG);

    }
}

然后在AndroidManifest.xml里编辑App类：

android:name=".App"


之后在MainActivity操作：

public class MainActivity extends AppCompatActivity {
    private ListView lv;                                  //ListView控件

    private List<Data.DataBean> list=new ArrayList<>();  //封装数据的Date类
    private MyBaseAdapter adapter;  //自定义的配置器 
   @Override   
 protected void onCreate(Bundle savedInstanceState) {   
     super.onCreate(savedInstanceState);     
     setContentView(R.layout.activity_main);
     lv= (ListView) findViewById(R.id.lv);
     getHttp();  
  
        adapter=new MyBaseAdapter(MainActivity.this,list);
        lv.setAdapter(adapter);

    }

    private void getHttp() {
        RequestParams requestParams=new RequestParams("http://api.expoon.com/AppNews/getNewsList/type/1/p/1");

        x.http().get(requestParams, new Callback.CommonCallback<String>() {
            @Override
            public void onSuccess(String result) {
                Data data = new Gson().fromJson(result, Data.class);
                list=data.getData();
                adapter=new MyBaseAdapter(MainActivity.this,list);
                lv.setAdapter(adapter);
                System.out.println(list);

            }

            @Override
            public void onError(Throwable ex, boolean isOnCallback) {

            }

            @Override
            public void onCancelled(CancelledException cex) {

            }

            @Override
            public void onFinished() {

            }
        });

    }
}
