要实现Android通知不消失的功能,可以通过以下方法:
方法一:设置通知的标志位
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, CHANNEL_ID)
.setSmallIcon(R.drawable.ic_notification)
.setContentTitle("Notification Title")
.setContentText("Notification Content")
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setOngoing(true); // 设置为持续通知,不会被滑动或清除按钮移除
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);
notificationManager.notify(notificationId, builder.build());
方法二:设置通知的重要性
NotificationChannel channel = new NotificationChannel(CHANNEL_ID, "Channel Name", NotificationManager.IMPORTANCE_HIGH);
channel.setLockscreenVisibility(Notification.VISIBILITY_PUBLIC); // 在锁屏状态下可见
channel.setSound(null, null); // 不播放通知声音
channel.enableVibration(false); // 禁用震动
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, CHANNEL_ID)
.setSmallIcon(R.drawable.ic_notification)
.setContentTitle("Notification Title")
.setContentText("Notification Content")
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setChannelId(CHANNEL_ID);
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);
notificationManager.createNotificationChannel(channel);
notificationManager.notify(notificationId, builder.build());
以上两种方法可以根据需求选择其中一种或结合使用。需要注意的是,通知不消失可能会干扰用户体验,因此在使用时应慎重考虑。
