实例代码：
(new OnHttpListener() {@Overridepublic void onStart() {// TODO Auto-generated method stubsuper.onStart();}@Overridepublic void onProgress(int mProgress, String message) {// TODO Auto-generated method stubsuper.onProgress(mProgress, message);}@Overridepublic void onSuccess(boolean status, int resultCode, String message,String data) {// TODO Auto-generated method stub}@Overridepublic void onFail(Exception e, String message) {// TODO Auto-generated method stub}@Overridepublic void onFinish() {// TODO Auto-generated method stubsuper.onFinish();}});开发中经常遇到这类代码，，看上去很神秘，onSuccess(),onFail 两个方法重载，其他方法需要就自己调用，其实很简单，不废话，直接上代码：
/** * 流程控制开始和结束回调函数 * @author LanYan * */public abstract interface OnProcessListener extends BaseListener {/** * 开始任务 */void onStart();/** * 任务结束 */void onFinish();}进度控制：
/** * 进度控制 * @author LanYan * */public abstract class OnProgressListener implements OnProcessListener{/** * 进度条的显示控制 * @param mProgress * @param message */public abstract void onProgress(int mProgress,String message);@Overridepublic void onStart() {// TODO Auto-generated method stub}@Overridepublic void onFinish() {// TODO Auto-generated method stub}Htt请求：
/** * HTTP访问进度控制 * @author LanYan * */public abstract class OnHttpListener extends OnProgressListener{@Overridepublic void onProgress(int mProgress, String message) {// TODO Auto-generated method stub}/** * 请求失败回调函数，返回异常信息和状态码 * @param e * @param message */public abstract void onFail(Exception e,String message);/** * 请求成功回调函数，返回响应数据 * @param status * @param message * @param data * @param resultCode */public abstract void onSuccess(boolean status,int resultCode,String message,String data);}测试类：
public class Test {public static void main(String[] args) {getHttpData(HttpType.post, url, parmas, new OnHttpListener() {/*@Overridepublic void onStart() {// TODO Auto-generated method stubsuper.onStart();}*/@Overridepublic void onSuccess(boolean status, int resultCode, String message,String data) {// TODO Auto-generated method stub}@Overridepublic void onFail(Exception e, String message) {// TODO Auto-generated method stub}/*@Overridepublic void onFinish() {// TODO Auto-generated method stubsuper.onFinish();}*/});}public static void getHttpData(String type,String url,NameValuePair parmas,OnHttpListener listener){}public enum HttpType{get,post,defult}}
青春气贯长虹，勇敢盖过怯懦，进取压倒苟安。
