Is it possible to display ProgressBar or ProgressDialog from my
DownloadService (which is extended IntentService), except the progress
shown in the Notification bar?
Could you write a sample code or pseudo code how I can do that? Thank
you
You can use ResultReceiver to reach your goal. ResultReceiver implements Parcelable so you are able to pass it into IntentService like:
Intent i = new Intent(this, DownloadService.class);
i.putExtra("receiver", new DownReceiver(new Handler()));
<context>.startService(i);
Then in your onHandlerIntent() all what you need is to obtain receiver you passed into Intent and send current progress into ResultReceiver:
protected void onHandleIntent(Intent intent) {
// obtaining ResultReceiver from Intent that started this IntentService
ResultReceiver receiver = intent.getParcelableExtra("receiver");
...
// data that will be send into ResultReceiver
Bundle data = new Bundle();
data.putInt("progress", progress);
// here you are sending progress into ResultReceiver located in your Activity
receiver.send(Const.NEW_PROGRESS, data);
}
And ResultReceiver will handle data and will make update in ProgressDialog. Here is implementation of ResultReceiver (make it as inner class of your Activity class):
private class DownReceiver extends ResultReceiver {
public DownloadReceiver(Handler handler) {
super(handler);
}
@Override
public void onReceiveResult(int resultCode, Bundle resultData) {
super.onReceiveResult(resultCode, resultData);
if (resultCode == Const.NEW_PROGRESS) {
int progress = resultData.getInt("progress");
// pd variable represents your ProgressDialog
pd.setProgress(progress);
pd.setMessage(String.valueOf(progress) + "% downloaded sucessfully.");
}
}
}
