我有以下代码AsyncTask。文件上传得很好，我正在尝试实现一个进度条。我遇到的问题是它从 0 开始，然后就跳到 100。

我哪里做错了？

public class UploadingAsync extends AsyncTask<String, Integer, Object> {

  ProgressDialog dialog;
  BaseActivity base;

  public FileUploadAsyncTask(BaseActivity base) {
    this.base = base;
  }

  @Override
  protected Object doInBackground(String... path) {
    try {
      DroplrApp api = ((DroplrApplication) base.getApplication()).getDroplrAppApi();

      File file = new File(path[0]);

      Log.e("File uploaded", file.getAbsolutePath().toString());

      api.upload(file, new DroplrAppProgressListener() {

        @Override
        public void transferred(long transfer, long total) {
          publishProgress((int) (total * 100 / transfer));
        }
      });
    } catch (DroplrAppException e) {
      Log.e("Something is wrong", "Problem uploading");
    }

    return null;
  }

  @Override
  protected void onPreExecute() {
    super.onPreExecute();
    dialog = new ProgressDialog(base);
    dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
        dialog.setMessage("Uploading...");
        dialog.setIndeterminate(false);
        dialog.setCancelable(false);
        dialog.setMax(100);
        dialog.setProgress(0);
        dialog.show();
  }

  @Override
  protected void onPostExecute(Object result) {
    super.onPostExecute(result);
    dialog.dismiss();
  }

  @Override
  protected void onProgressUpdate(Integer... progress) {
    super.onProgressUpdate(progress);
    Log.e("progress", progress[0].toString());
    dialog.setProgress(progress[0]);
  }

}

这是输出Log.e("progress", progress[0].toString());
