Question

我正在从服务器下载文件。代码在下面
单击下载后，我在服务器中就有图像和声音以及文本文件，因此它将获取所有数据（多个文件）

由于我的波纹管代码在下载数据时显示了带有计数对话框的百分比，但是问题是百分比对话框显示了每一个数据长度，但是我需要对话框显示所有内容的百分比，而不仅仅是一个内容

    private void downloadFiles(String pMain, String pFileName String pURL) {
    Log.i(TAG, "Coming to this downloadBookDetails ");
    int len;
    try {
        URL url = new URL(pURL);
        Log.i(TAG, "pDownload URL" + url);
        URLConnection ucon = url.openConnection();
        ucon.setReadTimeout(5000);
        ucon.setConnectTimeout(10000);
        ucon.connect();
        int lenghtOfFile = ucon.getContentLength();
        Log.i(TAG, "lenght of file" + lenghtOfFile);
        InputStream is = ucon.getInputStream();
        BufferedInputStream inStream = new BufferedInputStream(is, 1024 * 5);
        File directory = new File(pMainFolder, pFileName);
        Log.i(TAG, "File Name dir" + directory);
        FileOutputStream outStream = new FileOutputStream(directory);
        byte[] buff = new byte[5 * 1024];
        long total = 0;
        while ((len = inStream.read(buff)) != -1) {
            total += len;
            publishProgress("" + (int) ((total * 100) / lenghtOfFile));
            Log.i(TAG, "Progress: Bar with Count " + (int) ((total * 100) / lenghtOfFile));
            outStream.write(buff, 0, len);
        }
        outStream.flush();
        outStream.close();
        inStream.close();
    } catch (Exception e) {
        //Add Network Error.
        Log.i(TAG, "Download Error Exception " + e.getMessage());

        e.printStackTrace();
    }
}
