android怎么保证notification不重复

Posted 2023-03-26

参考技术A 谷歌的通知提供了一个唯一的id参数,只要设置不同的id,就可以避免重复:
private
void
showNotification(String
title,
Context
context)

int
requestCode
=
(int)
System.currentTimeMillis();
NotificationManager
notificationManager
=
(NotificationManager)
context
.getSystemService(android.content.Context.NOTIFICATION_SERVICE);
Notification
notification
=
new
Notification(R.drawable.ic_launcher,
"90
上门洗车
",
System.currentTimeMillis());
notification.flags
=
Notification.FLAG_AUTO_CANCEL;
notification.defaults
|=
Notification.DEFAULT_VIBRATE;
notification.defaults
|=
Notification.DEFAULT_SOUND;
notification.defaults
|=
Notification.DEFAULT_LIGHTS;
notification.vibrate
=
new
long[]0,
100,
200,
300;
Intent
intent
=
null;
if
(pushType
==
1)

intent
=
new
Intent(context,
Advertisement
.class);

else
if
(pushType
==
2)

intent
=
new
Intent(context,
HomePage.class);

else
if
(pushType
==
3)

intent
=
new
Intent(context,
OrderList.class);

PendingIntent
contentIntent
=
PendingIntent.getActivity(context,
0,
intent,
0);
notification.setLatestEventInfo(context,
"90上门洗车",
title,
contentIntent);
notificationManager.notify(requestCode,
notification);

在这里，我把notify（）里面的id参数变成了
时间戳
，编译，运行
