Android网络通信的实现方式

这篇文章主要为大家详细介绍了Android网络通信的实现方式,四种实现网络通信的方式供大家学习,感兴趣的小伙伴们可以参考一下

Android网络编程分为两种:基于http协议的,和基于socket的。
基于Http协议:HttpClient、HttpURLConnection、AsyncHttpClient框架等
基于Socket
(1)针对TCP/IP的Socket、ServerSocket
(2)针对UDP/IP的DatagramSocket、DatagramPackage
(3)Apache Mina框架
一、HttpURLConnection的实现方式

 String respOnse= null; Url url = new URL(path); HttpURLConnection cOnnection= (HttpURLConnection) url.openConnection(); // 新建连接实例 connection.setConnectTimeout(20000);// 设置连接超时时间,单位毫秒 //connection.setReadTimeout(20000);// 设置读取数据超时时间,单位毫秒 connection.setDoInput(true);// 是否打开输入流 true|false connection.setRequestMethod("POST");// 提交方法POST|GET //connection.setUseCaches(false);// 是否缓存true|false //connection.setRequestProperty("accept", "*/*"); //connection.setRequestProperty("Connection", "Keep-Alive"); //connection.setRequestProperty("Charset", "UTF-8"); //connection.setRequestProperty("Content-Length", String.valueOf(data.length)); //connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); connection.connect();// 打开连接端口 int respOnseCode= conn.getResponseCode(); BufferedReader reader = null; if (respOnseCode== 200) { reader = new BufferedReader(new InputStreamReader(connection.getInputStream(), "utf-8")); StringBuffer buffer = new StringBuffer(); String line = ""; while ((line = reader.readLine()) != null) { buffer.append(line); } respOnse= buffer.toString(); } else { respOnse= "返回码:"+responseCode; } reader.close(); conn.disconnect(); 

二、HttpClient实现方式

 HttpResponse mHttpRespOnse= null; HttpEntity mHttpEntity = null; //创建HttpPost对象 //HttpPost httppost = new HttpPost(path); //设置httpPost请求参数 //httppost.setEntity(new UrlEncodedFormEntity(params,HTTP.UTF_8)); HttpGet httpGet = new HttpGet(path); HttpClient httpClient = new DefaultHttpClient(); InputStream inputStream = null; BufferedReader bufReader = null; String result = ""; // 发送请求并获得响应对象 mHttpRespOnse= httpClient.execute(httpGet);//如果是“POST”方式就传httppost if (mHttpResponse.getStatusLine().getStatusCode() == HttpStatus.SC_OK) { // 获得响应的消息实体 mHttpEntity = mHttpResponse.getEntity(); // 获取一个输入流 inputStream = mHttpEntity.getContent(); bufReader = new BufferedReader(new InputStreamReader(inputStream)); String line = ""; while (null != (line = bufReader.readLine())) { result += line; } //result = EntityUtils.toString(mHttpResponse.getEntity()); } if (inputStream != null) { inputStream.close(); } bufReader.close(); if (httpClient != null) { httpClient.getConnectionManager().shutdown(); } 

三、实用AsyncHttpClient框架的实现方式

 AsyncHttpClient client = new AsyncHttpClient(); client.get(url, new AsyncHttpResponseHandler() { @Override public void onSuccess(int i, Header[] headers, byte[] bytes) { String respOnse= new String(bytes, 0, bytes.length, "UTF-8"); } @Override public void onFailure(int i, Header[] headers, byte[] bytes, Throwable throwable) { } }); 

四、使用WebView视图组件显示网页

 myWebView.getSettings().setJavascriptEnabled(true); myWebView.setWebViewClient(new WebViewClient() { @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { view.loadUrl(url); return true; } }); myWebView.loadUrl("http://"+networkAddress); 

以上就是Android中网络通信几种方式的全部内容,希望对大家的学习有所帮助。
