Comment afficher la barre de progression dans la zone de notification?

Après une longue recherche, j'ai fini la tâche de montrer la barre de progression dans la zone de notification.Tous nous avons besoin est asynctask.Peut-être le code iam montrant ici ne fonctionne pas parfaitement,Il fonctionne très bien lorsque iam tests.Veuillez vérifier et upvote pour cette réponse si il fonctionne bien.

Mon code:

public class loadVideo extends AsyncTask<Void, Integer, Void> {
int progress = 0;
Notification notification;
NotificationManager notificationManager;
int id = 10;
protected void onPreExecute() {
}
@Override
protected Void doInBackground(Void... params) {
HttpURLConnection conn = null;
DataOutputStream dos = null;
DataInputStream inStream = null;
String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead;
int sentData = 0;               
byte[] buffer;
String urlString = "http://xxxxx/xxx/xxxxxx.php";
try {
UUID uniqueKey = UUID.randomUUID();
fname = uniqueKey.toString();
Log.e("UNIQUE NAME", fname);
FileInputStream fileInputStream = new FileInputStream(new File(
selectedPath));
int length = fileInputStream.available();
URL url = new URL(urlString);
conn = (HttpURLConnection) url.openConnection();
conn.setDoInput(true);
conn.setDoOutput(true);
conn.setUseCaches(false);
conn.setRequestMethod("POST");
conn.setRequestProperty("Connection", "Keep-Alive");
conn.setRequestProperty("Content-Type",
"multipart/form-data;boundary=" + boundary);
dos = new DataOutputStream(conn.getOutputStream());
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\""
+ fname + "" + lineEnd);
dos.writeBytes(lineEnd);
buffer = new byte[8192];
bytesRead = 0;
while ((bytesRead = fileInputStream.read(buffer)) > 0) {
dos.write(buffer, 0, bytesRead);
sentData += bytesRead;
int progress = (int) ((sentData / (float) length) * 100);
publishProgress(progress);
}
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
Log.e("Debug", "File is written");
fileInputStream.close();
dos.flush();
dos.close();
} catch (MalformedURLException ex) {
Log.e("Debug", "error: " + ex.getMessage(), ex);
} catch (IOException ioe) {
Log.e("Debug", "error: " + ioe.getMessage(), ioe);
}
//------------------ read the SERVER RESPONSE
try {
inStream = new DataInputStream(conn.getInputStream());
String str;
while ((str = inStream.readLine()) != null) {
Log.e("Debug", "Server Response " + str);
}
inStream.close();
} catch (IOException ioex) {
Log.e("Debug", "error: " + ioex.getMessage(), ioex);
}
return null;
}
@Override
protected void onProgressUpdate(Integer... progress) {
Intent intent = new Intent();
final PendingIntent pendingIntent = PendingIntent.getActivity(
getApplicationContext(), 0, intent, 0);
notification = new Notification(R.drawable.video_upload,
"Uploading file", System.currentTimeMillis());
notification.flags = notification.flags
| Notification.FLAG_ONGOING_EVENT;
notification.contentView = new RemoteViews(getApplicationContext()
.getPackageName(), R.layout.upload_progress_bar);
notification.contentIntent = pendingIntent;
notification.contentView.setImageViewResource(R.id.status_icon,
R.drawable.video_upload);
notification.contentView.setTextViewText(R.id.status_text,
"Uploading...");
notification.contentView.setProgressBar(R.id.progressBar1, 100,
progress[0], false);
getApplicationContext();
notificationManager = (NotificationManager) getApplicationContext()
.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(id, notification);
}
protected void onPostExecute(Void result) {
Notification notification = new Notification();
Intent intent1 = new Intent(MultiThreadActivity.this,
MultiThreadActivity.class);
final PendingIntent pendingIntent = PendingIntent.getActivity(
getApplicationContext(), 0, intent1, 0);
int icon = R.drawable.check_16; //icon from resources
CharSequence tickerText = "Video Uploaded Successfully"; //ticker-text
CharSequence contentTitle = getResources().getString(
R.string.app_name); //expanded message
//title
CharSequence contentText = "Video Uploaded Successfully"; //expanded
//message
long when = System.currentTimeMillis(); //notification time
Context context = getApplicationContext(); //application
//Context
notification = new Notification(icon, tickerText, when);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notification.setLatestEventInfo(context, contentTitle, contentText,
pendingIntent);
String notificationService = Context.NOTIFICATION_SERVICE;
notificationManager = (NotificationManager) context
.getSystemService(notificationService);
notificationManager.notify(id, notification);
}
}

Merci et Salutations

Dans RemoveView, vous pouvez mettre à jour la barre de Progression. Donc, la combinaison de certaines de l'exemple des codes, j'obtiens quelque chose comme ceci:

public class MyActivity extends Activity {
private static final int PROGRESS = 0x1;
private static final int MAX_PROGRESS = 100;
private int mProgressStatus = 0;
private Handler mHandler = new Handler();
protected void onCreate(Bundle icicle) {
super.onCreate(icicle);
//define Notification
//...
RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.custom_notification_layout);
contentView.setProgressBar(R.id.progress_bar, MAX_PROGRESS, mProgressStatus, false);
notification.contentView = contentView;
//Start file upload in a background thread
new Thread(new Runnable() {
public void run() {
while (mProgressStatus < MAX_PROGRESS) {
mProgressStatus = doWork();
//Update the progress bar
mHandler.post(new Runnable() {
public void run() {
contentView.setProgressBar(R.id.progress_bar, MAX_PROGRESS, mProgressStatus, false);
}
});
}
}
}).start();
}
}

Ce post de blog a un très bon exemple de la mise en œuvre de la même. Espérons que cette aide.
