xUtils的網路請求簡單封裝
其他的前提條件就不多說了，只要你會使用xutils就完全可以使用。不多說了，直接上程式碼。
HttpxUtils.java類：

*/
public class HttpxUtils {
/**

* @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;
}
/**

*

*/
public static <T> Cancelable Post(String url, Map<String, Object> map, CommonCallback<T> callback) {

簡單測試用例：

private Button btn_post;// post請求
@ViewInject(R.id.btn_load)
private Button btn_load;// 上傳檔案
@ViewInject(R.id.btn_down)
private Button btn_down;// 下載檔案
@ViewInject(R.id.btn_get_xml)
private Button btn_get_xml;// 傳送get請求(伺服器以xml格式返回)
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
x.view().inject(this);// 初始化
}
