我的问题是我无法从我的AsyncTask.
我在这个问题上花了很长时间，但没有找到解决方案。我的目标是只能更改对话框进度条和文本。
我怎样才能使这个通知进度条工作？
这是我的代码：
private class excuteUploadFile extends
AsyncTask<HttpResponse, Integer, HttpResponse> {
long totalSize;
int NOTIFICATION_ID;
String filepath, fileName;
String serverResponse = null;
String urlServer = "http://myurl";
NotificationManager mNotifyManager;
Builder mBuilder;
ProgressDialog pd;
Boolean nofti_appended = false;
JSONObject jsonfile = null;
public excuteUploadFile(String filepath, String fileName) {
this.filepath = filepath;
this.fileName = fileName;
Log.i("uploader", "Selected file name : " + fileName);
Log.i("uploader", "Selected file path : " + filepath);
}
@Override
protected void onPreExecute() {
pd = new ProgressDialog(BabupMain.this);
// pd.setMessage(getResources().getString(R.string.uploading_file));
pd.setTitle(fileName);
pd.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
pd.setCancelable(false);
pd.setIcon(android.R.drawable.ic_menu_upload);
pd.setButton(DialogInterface.BUTTON_NEGATIVE,
getResources().getString(R.string.cancel),
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
cancel(true);
}
});
// hide button
pd.setButton(DialogInterface.BUTTON_NEUTRAL,
getResources().getString(R.string.hide),
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
Random r = new Random();
NOTIFICATION_ID = r.nextInt(80 - 65) + 1;
NOTIFICATION_ID++;
mNotifyManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
mBuilder = new NotificationCompat.Builder(
BabupMain.this);
mBuilder.setContentTitle(fileName)
.setContentText(
getResources().getString(
R.string.uploading_file))
.setOngoing(true)
.setSmallIcon(android.R.drawable.ic_menu_upload);
mBuilder.setProgress(100, 100, true);
mNotifyManager.notify(NOTIFICATION_ID, mBuilder.build());
nofti_appended = true;
}
});
pd.show();
}
@Override
protected HttpResponse doInBackground(HttpResponse... arg0) {
HttpClient httpClient = new DefaultHttpClient();
HttpContext httpContext = new BasicHttpContext();
HttpPost httpPost = new HttpPost(urlServer);
try {
Log.i("uploader", "Started " + fileName);
if (isCancelled()) {
og.i("uploader", "uploading has been canceled");
}
CustomMultiPartEntity multipartContent = new CustomMultiPartEntity(
new ProgressListener() {
@Override
public void transferred(long num) {
publishProgress((int) ((num / (float) totalSize) * 100));
Log.i("uploader", "uploading " + num + " OF "
+ totalSize);
}
});
multipartContent.addPart("file", new FileBody(new File(filepath)));
totalSize = multipartContent.getContentLength();
Log.i("uploader", "Bytes to Send " + totalSize);
// Send it
httpPost.setEntity(multipartContent);
HttpResponse response = httpClient.execute(httpPost, httpContext);
serverResponse = EntityUtils.toString(response.getEntity());
Log.i("uploader", "Server Response : " + serverResponse);
return null;
} catch (Exception e) {
Log.i("uploader", "Uploading Error : " + e.getMessage());
}
return null;
}
@Override
protected void onCancelled() {
super.onCancelled();
if (nofti_appended) {
mNotifyManager.cancel(NOTIFICATION_ID);
} else {
pd.dismiss();
}
}
@Override
protected void onProgressUpdate(Integer... progress) {
if (nofti_appended == true) {
mBuilder.setProgress(100, progress[0], false);
} else {
pd.setProgress((int) (progress[0]));
}
}

@Override
protected void onPostExecute(HttpResponse ui) {
Log.i("uploader", "Done: " + fileName);
}
}
