for循環，下載進度一直有聲音啊，怎么解決？

for?(int?i?=?0;?i?<?100;?i++)?{
????????????????????try?{
????????????????????????Thread.sleep(1000);//1秒后更新一下
????????????????????????builder.setDefaults(Notification.FLAG_ONLY_ALERT_ONCE);
????????????????????????//設置進度，max最大進度值，progress當前進度，indeterminate不確定的
????????????????????????builder.setProgress(100,i,false);
????????????????????????getManager().notify(2,builder.build());
????????????????????}?catch?(InterruptedException?e)?{
????????????????????????e.printStackTrace();
????????????????????}
????????????????}

Notification.Builder?builder?=?new?Notification.Builder(this)
????????.setAutoCancel(true)
????????.setChannelId("test_channel_id")
????????.setContentTitle("新消息來了")
????????.setContentText("明天是周末，不用上班？你怕是在做夢！")
????????.setOnlyAlertOnce(true)
????????.setSmallIcon(R.mipmap.ic_launcher);

manager.notify(1,?builder.build());

new?Thread(new?Runnable()?{
????@Override
????public?void?run()?{
????????for?(int?i?=?0;?i?<?100;?i++)?{
????????????try?{
????????????????Thread.sleep(1000);
????????????????builder.setProgress(100,?i,?false);

????????????????manager.notify(1,?builder.build());
????????????}?catch?(InterruptedException?e)?{
????????????????e.printStackTrace();
????????????}

????????}
????}
}).start();

設置builder.setDefaults(Notification.FLAG_ONLY_ALERT_ONCE);這個是沒有效果的
