android - 如何动画进度通知图标

Question

我正在按照下面给出的方式在服务中构建通知进度条:

private NotificationManager mNotifyManager;
private NotificationCompat.Builder mBuilder;



 mBuilder =
                    new NotificationCompat.Builder(DownloadService.this)
                            .setSmallIcon(R.drawable.download)
                            .setContentTitle("MayUp")
                            .setContentText("Downloading new tools")
                            .setTicker("Downloading in progress");
            mBuilder.setAutoCancel(true);
            Intent targetIntent = new Intent(DownloadService.this, ListClass.class);
            TaskStackBuilder stackBuilder = TaskStackBuilder.create(DownloadService.this);
            // Adds the back stack for the Intent (but not the Intent itself)
            stackBuilder.addParentStack(MyActivity.class);
            // Adds the Intent that starts the Activity to the top of the stack
            stackBuilder.addNextIntent(targetIntent);
//            PendingIntent contentIntent = PendingIntent.getActivity(DownloadService.this, 0, targetIntent, PendingIntent.FLAG_UPDATE_CURRENT);
//            mBuilder.setContentIntent(contentIntent);
            PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0,
                    PendingIntent.FLAG_UPDATE_CURRENT);
            mBuilder.setContentIntent(resultPendingIntent);

            mNotifyManager.notify(1, mBuilder.build());

            mBuilder.setProgress(100, 0, false);
            mNotifyManager.notify(1, mBuilder.build());

它工作正常，通知和进度条显示一切正常，我想要通知中的简单进度条，它很简单，我对此没有问题，但我想要的如下:

我想要的:

I want that My notification Icon should animate like the google play store app does, it animates its icon to show that download in progress. I want to do the same. Please tell me by using builder and notification manager How can I get this , I have seen many tutorial but they are deprecated.

通过使用此代码，您可以使用动画图标显示下载某些文件的通知:

mBuilder.setContentTitle("Downloading... ")
        .setContentText("Please wait...")
        .setOngoing(true)
        .setOnlyAlertOnce(true)
        .setSmallIcon(android.R.drawable.stat_sys_download)  // here is the animated icon
        .setLargeIcon(BitmapFactory.decodeResource(this.getResources(), android.R.drawable.stat_sys_download)).build();
