【问题描述】:
我正在使用 channel_id 创建一个自定义通知并将其作为前台启动。我正在播放背景音乐.. 我的问题是当用户滑动通知时它消失了。我也有 setOngoing(true)。我希望在播放音乐时保留通知。
注意:它只发生在 Oreo+ 中。在较低版本中它工作正常。
public void CustomNotification() {
remoteViews = new RemoteViews(getPackageName(), R.layout.player_noti_layout);
notificationmanager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel("default",
getString(R.string.player_channel),
NotificationManager.IMPORTANCE_LOW);
channel.enableVibration(true);
channel.enableLights(true);
channel.setLockscreenVisibility(Notification.VISIBILITY_PUBLIC);
channel.setDescription("Notification, Play/pause & Next/Prev");
notificationmanager.createNotificationChannel(channel);
}
builder = new NotificationCompat.Builder(this, "default");
Notification foregroundNote;
// Set icon
foregroundNote = builder.setSmallIcon(R.drawable.ic_radio)
.setLargeIcon(R.drawable.cool_1)
// Set ticker message
.setTicker(getResources().getString(R.string.app_name))
// Dismiss notification
.setAutoCancel(false)
.setOngoing(true)
.setContent(remoteViews)
.setContentTitle("title").
setContentText("text")
.build();
foregroundNote.flags |= Notification.FLAG_ONGOING_EVENT;
foregroundNote.flags |= Notification.FLAG_NO_CLEAR;
foregroundNote.contentView = remoteViews;
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
startForeground(2, foregroundNote);
} else
notificationmanager.notify(2, foregroundNote);
}
