Android网络通信的实现方式

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。
