GET 提交

URL url=new URL("http://www.15780.cn/get.php");     //新建URL对象

HttpURLConnection connection = (HttpURLConnection)url.openConnection();  //新建URL链接返回对象

//设置该连接允许读取
 connection.setDoInput(true);
 //设置该连接允许写入
 connection.setDoOutput(true);
 //设置超时
connection.setConnectTimeout(1000);

//得到连接的输入流

InputStreamReader isr = new InputStreamReader(connection.getInputStream());

//再次包装为缓冲流
 BufferedReader br = new BufferedReader(isr);
 //用来存放临时读取的行
 String tempResult = null;
  //用来保存全部的结果
 String result = null;
 //不停地读取行，知道结束
  while((tempResult = br.readLine()) != null)

       //将结果保存
      result += tempResult + "\n" ;
  }

t.setText("取到啥了"+Html.fromHtml(result));    // Html.fromHtml() 将字符串转化成HTML 否则 会显示html代码
 br.close();

isr.close();

传递中文字符  message = java.net.URLEncoder.encode("中文字符","utf-8");
