xUtils的网络请求简单封装

其他的前提条件就不多说了，只要你会使用xutils就完全可以使用。不多说了，直接上代码。

HttpxUtils.java类：

/**

 * @Title 封装xUtils网络请求

 * @Authour zhoujp

 * @Time 2016年7月27日 下午3:25:21

 * 

 */

public class HttpxUtils {
/**
* 发送get请求
* 
* @param <T>
*/
public static <T> Cancelable Get(String url, Map<String, String> map, CommonCallback<T> callback) {
RequestParams params = new RequestParams(url);
if (null != map) {
for (Map.Entry<String, String> entry : map.entrySet()) {
params.addQueryStringParameter(entry.getKey(), entry.getValue());
}
}
Cancelable cancelable = x.http().get(params, callback);
return cancelable;
}

/**
* 发送post请求
* 
* @param <T>
*/
public static <T> Cancelable Post(String url, Map<String, Object> map, CommonCallback<T> callback) {
RequestParams params = new RequestParams(url);
if (null != map) {
for (Map.Entry<String, Object> entry : map.entrySet()) {
params.addParameter(entry.getKey(), entry.getValue());
}
}
Cancelable cancelable = x.http().post(params, callback);
return cancelable;
}

/**
* 上传文件
* 
* @param <T>
*/
public static <T> Cancelable UpLoadFile(String url, Map<String, Object> map, CommonCallback<T> callback) {
RequestParams params = new RequestParams(url);
if (null != map) {
for (Map.Entry<String, Object> entry : map.entrySet()) {
params.addParameter(entry.getKey(), entry.getValue());
}
}
params.setMultipart(true);
Cancelable cancelable = x.http().get(params, callback);
return cancelable;
}

/**
* 下载文件
* 
* @param <T>
*/
public static <T> Cancelable DownLoadFile(String url, String filepath, CommonCallback<T> callback) {
RequestParams params = new RequestParams(url);
// 设置断点续传
params.setAutoResume(true);
params.setSaveFilePath(filepath);
Cancelable cancelable = x.http().get(params, callback);
return cancelable;
}

public class JsonResponseParser implements ResponseParser {
// 检查服务器返回的响应头信息
@Override
public void checkResponse(UriRequest request) throws Throwable {
}

/**
* 转换result为resultType类型的对象
* 
* @param resultType
*            返回值类型(可能带有泛型信息)
* @param resultClass
*            返回值类型
* @param result
*            字符串数据
* @return
* @throws Throwable
*/
@Override
public Object parse(Type resultType, Class<?> resultClass, String result) throws Throwable {
return new Gson().fromJson(result, resultClass);
}
}

简单测试用例：

@ContentView(R.layout.activity_main)

public class MainActivity extends Activity {

private Button btn_get;// get请求

@ViewInject(R.id.btn_post)
private Button btn_post;// post请求

@ViewInject(R.id.btn_load)
private Button btn_load;// 上传文件

@ViewInject(R.id.btn_down)
private Button btn_down;// 下载文件

@ViewInject(R.id.btn_get_xml)
private Button btn_get_xml;// 发送get请求(服务器以xml格式返回)

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
x.view().inject(this);// 初始化
}
@Event(value = { R.id.btn_get, R.id.btn_post, R.id.btn_load, R.id.btn_down, R.id.btn_get_xml })
