使用Java，如何给Android设置 HttpResponse超时？

Question

为了检查网络连接的情况，我创建了下边的方法：

private void checkConnectionStatus() {
    HttpClient httpClient = new DefaultHttpClient();

    try {
      String url = "http://xxx.xxx.xxx.xxx:8000/GaitLink/"
                   + strSessionString + "/ConnectionStatus";
      Log.d("phobos", "performing get " + url);
      HttpGet method = new HttpGet(new URI(url));
      HttpResponse response = httpClient.execute(method);

      if (response != null) {
        String result = getResponse(response.getEntity());
        ...

当我关闭服务器来测试执行的时候，需要等待很长的时间

HttpResponse response = httpClient.execute(method);

有人知道怎么设置超时来避免等待太长的时间吗？
谢谢！

在我的示例中有两个超时的设置。连接超时声明抛出异常"java.net.SocketTimeoutException: Socket is not connected"，Socket超时是"java.net.SocketTimeoutException: The operation timed out".

HttpGet httpGet = new HttpGet(url);
HttpParams httpParameters = new BasicHttpParams();
int timeoutConnection = 3000;
HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection);
int timeoutSocket = 5000;
HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);

DefaultHttpClient httpClient = new DefaultHttpClient(httpParameters);
HttpResponse response = httpClient.execute(httpGet);

如果你想给任何存在的HTTPClient（如DefaultHttpClient 或AndroidHttpClient）设置参数，你可以使用 setParams()方法。

httpClient.setParams(httpParameters);
