android如何知道HttpResponse需要多少时间才能做出回应

Question

我有一个应用程序，每次连接到互联网并从互联网上获取数据时，我都想找到它需要多少时间？如果需要更多时间，那么我想警告用户“Internet 连接有问题”

所以我怎么知道它需要多少时间。在我提供的应用程序功能下方，我使用了 HttpResponse。请告诉我如何获得它需要多少时间给予回应

 String page = executeHttpGet("http://192.168.1.109/temp/android.php");

 private String executeHttpGet(String URL) throws Exception {

    BufferedReader bufferedReader = null;
    try {
        HttpClient client = new DefaultHttpClient();
        client.getParams().setParameter(CoreProtocolPNames.USER_AGENT,
                "android");
        HttpGet request = new HttpGet();
        request.setHeader("Content-Type", "text/plain; charset=utf-8");
        request.setURI(new URI(URL));
        HttpResponse response = client.execute(request);
        bufferedReader = new BufferedReader(new InputStreamReader(response
                .getEntity().getContent()));

        StringBuffer stringBuffer = new StringBuffer("");
        String line = "";

        String NL = System.getProperty("line.separator");
        while ((line = bufferedReader.readLine()) != null) {
            stringBuffer.append(line + NL);
            System.out.print(stringBuffer);
        }
        bufferedReader.close();
        page = stringBuffer.toString();
        System.out.println(page + "page");
        return page;
    } finally {
        if (bufferedReader != null) {
            try {
                bufferedReader.close();
            } catch (IOException e) {
                Log.d("BBB", e.toString());
            }
        }
    }
}

谢谢。

..if takes more time then i want to give warning to...

既然您知道最佳时间，您应该得到响应，为什么不在创建连接时指定超时。有关如何设置超时的信息，请参见下面的代码 fragment 。然后您捕获超时错误并通知服务响应时间太长。

DefaultHttpClient httpClient = new DefaultHttpClient();
HttpParams params = httpClient.getParams();
HttpConnectionParams.setConnectionTimeout(params, 5000);
HttpConnectionParams.setSoTimeout(params, 5000);

ClientExecutor executor = new ApacheHttpClient4Executor(httpClient);
