通知进度条在更新Android时发出声音
我一直在像这样更新通知进度条。这被称为多次。但通知声音会多次发出。这很烦人通知进度条在更新Android时发出声音,android,notifications,Android,Notifications,我一直在像这样更新通知进度条。这被称为多次。但通知声音会多次发出。这很烦人 builder.setProgress(100, percentage, false); notificationManager.notify(notifycation.notificationId, notifycation.builder.build()); 这是通知代码 public void initProgressNotificaiton(Context context) {
builder.setProgress(100, percentage, false);
notificationManager.notify(notifycation.notificationId, notifycation.builder.build());
这是通知代码
public void initProgressNotificaiton(Context context) {
notificationManager = NotificationManagerCompat.from(context);
builder = new NotificationCompat.Builder(context, ChannelId);
builder.setContentTitle("Video Upload")
.setOngoing(true)
.setContentText("Upload in progress")
.setSound(null)
.setSmallIcon(R.drawable.upload)
.setPriority(NotificationCompat.PRIORITY_LOW);
notificationManager.notify(notificationId, builder.build());
}
信道码
public void createNotificationChannel(Context context) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
CharSequence name = "naem";
String description = "desc";
int importance = NotificationManager.IMPORTANCE_DEFAULT;
NotificationChannel channel = new NotificationChannel(ChannelId, name, importance);
channel.setSound(null, null);
channel.setDescription(description);
NotificationManager notificationManager = context.getSystemService(NotificationManager.class);
notificationManager.createNotificationChannel(channel);
}
我该如何解决这个问题?在API 30 Emulator上测试。添加一个标志以仅发出一次警报 试试这个:
Notification notification = builder.build();
notification.flags |= Notification.FLAG_ONLY_ALERT_ONCE;
notificationManager.notify(notificationId, notification);
