为android的HttpClient添加请求超时 .并作相应处理

try {               HttpGet request = new HttpGet("http://www.google.com/"); HttpParams params = new BasicHttpParams();              HttpConnectionParams.setConnectionTimeout(params, 5000); //设置连接超时             HttpConnectionParams.setSoTimeout(params, 10000); //设置请求超时              request.setParams(params);              String page = httpClient.execute(request,                         new BasicResponseHandler()); } catch (IOException e) {               // 处理超时 covers:               //        ClientProtocolException               //        ConnectTimeoutException               //        ConnectionPoolTimeoutException               //        SocketTimeoutException               e.printStackTrace();           }
