现在,只要我的项目在后端有一个Web服务.我习惯用这种结构/模式创建我的项目.
项目
> HttpMethods包
> HttpGetThread
> HttpPostThread
> HttpMultipartPostThread
>接口包
> IPostResponse
IPostResponse.java
@H_404_18@public interface IPostResponse { public void getResponse(String response); }HttpGetThread.java
@H_404_18@public class HttpGetThread extends Thread { private String url; private final int HTTP_OK = 200; private IPostResponse ipostObj; public HttpGetThread(String url,IPostResponse ipostObj) { this.url = url; this.ipostObj = ipostObj; } public void run() { try { HttpClient httpClient = new DefaultHttpClient(); HttpGet httpGet = new HttpGet(url); HttpResponse httpResponse = httpClient.execute(httpGet); int responseCode = httpResponse.getStatusLine().getStatusCode(); if (responseCode == HTTP_OK) { InputStream inputStream = httpResponse.getEntity().getContent(); int bufferCount = 0; StringBuffer buffer = new StringBuffer(); while ((bufferCount = inputStream.read()) != -1) { buffer.append((char) bufferCount); } ipostObj.getResponse(buffer.toString()); } } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } }HttpPost和HttpMultipartPost类中的方法相同,通过扩展Thread并具有一个构造函数和一个run方法.
然后,
我实现了一个活动的接口,并将该主活动扩展到所有其他活动,并通过使用参数创建Http类的对象来获取响应和调用,并调用obj.start();
我仍然相信：我缺少很多东西,或者这种结构很差.
我需要知道,对于Android应用程序来说,在大多数所有活动中实现Web Service调用,并且具有代码可重用性,我应该遵循哪种模式/结构？
我刚刚看到Facebook如何进行Web服务调用,例如登录/注销它有登录和注销侦听器.
是否有任何博客/文章/答案都有相同的文件？请问,任何用户都可以分享他/她的优秀经验和解决方案吗？
我更感兴趣的是“我的类和界面应该怎么样,应该采用哪种方法？”
解决方法
第一个也是大多数建议,为什么你不使用
Painless Threading即
AsyncTask
现在,第二件事创建一个可重复使用的代码,如下所示,您可以使用Request参数创建尽可能多的方法.
@H_404_18@public class JSONUtil { private static JSONUtil inst; private JSONUtil() { } public static JSONUtil getInstance() { if (inst == null) inst = new JSONUtil(); return inst; } /** * Request JSON based web service to get response * * @param url * - base URL * @param request * - JSON request * @return response * @throws ClientProtocolException * @throws IOException * @throws IllegalStateException * @throws JSONException */ public HttpResponse request(String url,JSONObject request) throws ClientProtocolException,IOException,IllegalStateException,JSONException { synchronized (inst) { DefaultHttpClient client = new DefaultHttpClient(); HttpPost post = new HttpPost(url); post.setEntity(new StringEntity(request.toString(),"utf-8")); HttpResponse response = client.execute(post); return response; } } public HttpResponse request(String url) throws ClientProtocolException,JSONException { synchronized (inst) { DefaultHttpClient client = new DefaultHttpClient(); HttpPost post = new HttpPost(url); post.addHeader("Cache-Control","no-cache"); HttpResponse response = client.execute(post); return response; } } }
