xutils获取网络数据易懂

第一步:

首先:我们先要加载依赖:

compile 'org.xutils:xutils:3.5.0'

 

第二步:

创建一个MyApplication继承自Application

public class MyApplication extends Application {

    @Override
    public void onCreate() {
        super.onCreate();
        x.Ext.init(MyApplication.this);
    }
}

然后再清单文件里面添加:

android:name=".MyApplication"

别忘记添加网络权限哦!

android:name=".MyApplication"
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    
        
            

            
        
    

 

第三步:

public class MainActivity extends AppCompatActivity implements View.OnClickListener {

    private Button button;
    private String path = "http://www.qubaobei.com/ios/cf/dish_list.php?stage_id=1&limit=20&page=1";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        initView();


    }

    private void initView() {
        button = (Button) findViewById(R.id.button);

        button.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.button:
                RequestParams params = new RequestParams(path);

                x.http().get(params, new Callback.CacheCallback() {
                    @Override
                    public void onSuccess(String result) {
                        Log.i("onSuccess",result);
                    }

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

                    }

                    @Override
                    public void onCancelled(CancelledException cex) {

                    }

                    @Override
                    public void onFinished() {

                    }

                    @Override
                    public boolean onCache(String result) {
                        return false;
                    }
                });

                break;
        }
    }
}

 

我们在使用的时候肯定不止只获取网络数据,还需要获取网络的图片或者本地的图片,详情请看:
