我想知道一些下载的进度.
当我从互联网上获取一些资源时,像这样:

        String myFeed = request.getURI().toString();
        URL url = new URL(myFeed);
        URLConnection connection = url.openConnection();
        HttpURLConnection httpConnection = (HttpURLConnection) connection;
        int responseCode = httpConnection.getResponseCode();
        if (responseCode == HttpURLConnection.HTTP_OK) {

            InputStream in = httpConnection.getInputStream();
            // Process the input stream
        }

当"InputStream in = httpConnection.getInputStream();"时 被调用,
文件的所有内容立即下载.

如果我使用:

        htttpResponse = httpClient.execute(httpRequestBase);

问题是一样的.

如何检测下载的实际进度？

谢谢你们!
