这是安卓的问题,我利用timer让应用在通知栏显示,我怎么利用一个button让应用不再通知呢

Question

import java.util.Timer;
import java.util.TimerTask;
import android.app.Notification;
import android.app.NotificationChannel;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.app.Service;
import android.content.Intent;
import android.graphics.BitmapFactory;
import android.graphics.Color;
import android.os.IBinder;
import android.util.Log;

public class PushService extends Service {

    static Timer timer=new Timer();
    //清除通知
    public static void cleanAllNotification() {
        NotificationManager mn= (NotificationManager) MainActivity.getContext().getSystemService(NOTIFICATION_SERVICE);
        mn.cancelAll();
        timer.cancel();
        timer = null;
        
    }

    //添加通知
    public static void addNotification(int delayTime,String tickerText,String contentTitle,String contentText)
    {
        if (null == timer ) {
            timer = new Timer();
        }
        Intent intent = new Intent(MainActivity.getContext(), PushService.class);
        intent.putExtra("delayTime", delayTime);
        intent.putExtra("tickerText", tickerText);
        intent.putExtra("contentTitle", contentTitle);
        intent.putExtra("contentText", contentText);
        MainActivity.getContext().startService(intent);
    }

    public void onCreate() {
        Log.e("addNotification", "===========create=======");
    }

    @Override
    public IBinder onBind(Intent arg0) {
        // TODO Auto-generated method stub
        return null;
    }

    public int onStartCommand(final Intent intent, int flags, int startId) {

        long period = 5*1000; //24小时一个周期
        int delay=intent.getIntExtra("delayTime",0);

        timer.schedule(new TimerTask() {

            @Override
            public void run() {
                // TODO Auto-generated method stub
                NotificationManager mn= (NotificationManager) PushService.this.getSystemService(NOTIFICATION_SERVICE);
                String id = "channel_1"; //自定义设置通道ID属性
                      String description = "123";//自定义设置通道描述属性
                      int importance = NotificationManager.IMPORTANCE_HIGH;//通知栏管理重要提示消息声音设定
                     
                      NotificationChannel mChannel = new NotificationChannel(id, "123", importance);//建立通知栏通道类（需要有ID，重要属性）
                      mChannel.setDescription(description); // 配置通知渠道的属性
                      mChannel.enableLights(true);// 设置通知出现时的闪灯（如果 android 设备支持的话）
                      mChannel.setLightColor(Color.RED);//设置闪灯颜色为红色
                      mChannel.enableVibration(true);   // 设置通知出现时的震动（如果 android 设备支持的话）
                      mChannel.setVibrationPattern(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400});
                     mn.createNotificationChannel(mChannel);////最后在notificationmanager中创建该通知渠道
                      Notification notification = new Notification.Builder(PushService.this, id)//创建Notification对象。
                              .setContentTitle("付款通知")  //设置通知标题
                              .setSmallIcon(R.drawable.ic_launcher_background)//设置通知小图标
                              .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher_background))//设置通知大图标
                              .setContentText("您已付款元")//设置通知内容
                              .setAutoCancel(true)//设置自动删除通知
                              .build();//运行

                      mn.notify((int) System.currentTimeMillis(),notification); //通知栏保留多条通知
            }
        },delay, period);

        return super.onStartCommand(intent, flags, startId);
    }

    @Override
    public void onDestroy(){
        Log.e("addNotification", "===========destroy=======");
        super.onDestroy();
    }
}

把timer停掉就行了，或者run中加一个while条件退出，按钮设置条件-true
