android - 如何知道在android中上传到服务器的文件百分比

Question

我正在使用此代码将文件从我的 android 上传到服务器，但我不知道上传了多少文件(例如 30MB 来自 100MB)!有什么办法吗？

String url = "http://yourserver";
File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath(),
    "yourfile");
try {
HttpClient httpclient = new DefaultHttpClient();

HttpPost httppost = new HttpPost(url);

InputStreamEntity reqEntity = new InputStreamEntity(
        new FileInputStream(file), -1);
reqEntity.setContentType("binary/octet-stream");
reqEntity.setChunked(true); // Send in multiple parts if needed
httppost.setEntity(reqEntity);
HttpResponse response = httpclient.execute(httppost);
//Do something with response...

} catch (Exception e) {
// show error
}

为此，您使用了 AsyncTask 并使用 publishProgress() 方法设置了 ProgressDialog 百分比。有关更多详细信息，请访问此 link .
