应该是：
defaultHttpClient = new DefaultHttpClient();
请求超时
defaultHttpClient.getParams().setParameter(CoreConnectionPNames.CONNECTION_TIMEOUT, 10000);
读取超时
defaultHttpClient.getParams().setParameter(CoreConnectionPNames.SO_TIMEOUT, 10000);
defaultHttpClient = new DefaultHttpClient();
请求超时
defaultHttpClient.getParams().setParameter(CoreConnectionPNames.CONNECTION_TIMEOUT, 10000);
读取超时
defaultHttpClient.getParams().setParameter(CoreConnectionPNames.SO_TIMEOUT, 10000);
