Android通知栏未更新所有值

Question

我有一个工作线程的服务。同时在while循环中，通知栏会更新。但并非所有值都得到更新，有时即使显示消息已完成仍未显示最后一个值。

我究竟做错了什么？这是基于Google docs

public class DownloadService extends Service {

    NotificationCompat.Builder builder;
    NotificationManagerCompat notificationManager;

    private int PROGRESS_CURRENT = 0;

    public DownloadService() {}

    @Override
    public void onCreate() {
        super.onCreate();
        Log.d("onCreate","Created");
    }


    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {

        if(this.isServiceRunning)return Service.START_NOT_STICKY;

        Log.d("onStartCommand","Started");

        this.isServiceRunning = true;
        int PROGRESS_MAX = 100;
        notificationManager = NotificationManagerCompat.from(this);

        builder = ((App)this.getApplicationContext()).getNotificationBuilder(
                "1",
                "Download",
                "downloading",
                "Downloading",
                "Hello");

        startForeground(1,builder.build());

        new Thread(()->{

            while(PROGRESS_CURRENT <=100){





                notificationManager.notify(1, builder.setProgress(PROGRESS_MAX, PROGRESS_CURRENT, false).build());



                PROGRESS_CURRENT++;

            }

          //Notification bar doesnt get updated?????

            notificationManager.notify(1, builder.setContentText("Completed").setProgress(0, 0, false).build());

        }).start();

        return Service.START_NOT_STICKY;
    }

}

您是否尝试在重新发布通知之前取消通知？

notificationManager.cancel(1);
notificationManager.notify(1, builder.setContentText("Completed").setProgress(0, 0, false).build());
