简短问题:
我正试图使用NotificationCompat.Builder类来创建将用于服务的通知,但由于某些原因,我要么看不到该通知,要么在应销毁服务(或停止在前台)时无法取消该通知。
我的代码:
@Override
public int onStartCommand(final Intent intent, final int flags, final int startId) {
final String action = intent == null ? null : intent.getAction();
Log.d("APP", "service action:" + action);
if (ACTION_ENABLE_STICKING.equals(action)) {
final NotificationCompat.Builder builder = new Builder(this);
builder.setSmallIcon(R.drawable.ic_launcher);
builder.setContentTitle("content title");
builder.setTicker("ticker");
builder.setContentText("content text");
final Intent notificationIntent = new Intent(this, FakeActivity.class);
final PendingIntent pi = PendingIntent.getActivity(this, 0, notificationIntent, 0);
builder.setContentIntent(pi);
final Notification notification = builder.build();
// notification.flags |= Notification.FLAG_FOREGROUND_SERVICE;
// notification.flags |= Notification.FLAG_NO_CLEAR;
// notification.flags |= Notification.FLAG_ONGOING_EVENT;
startForeground(NOTIFICATION_ID, notification);
// mNotificationManager.notify(NOTIFICATION_ID, notification);
} else if (ACTION_DISABLE_STICKING.equals(action)) {
stopForeground(true);
stopSelf();
// mNotificationManager.cancel(NOTIFICATION_ID);
}
return super.onStartCommand(intent, flags, startId);
}
评论的命令是我的试验,使之发挥作用。没有人因为某种原因而工作。
我甚至添加了一个假的活动,因为它想要一个内容意图,但它仍然不起作用。
有人能帮忙吗?
最佳答案
我刚才也遇到了同样的问题,我发现由于某种原因,通知id 0不能很好地与startForeground()
一起工作,这是代码中NOTIFICATION_ID
的值吗?
编辑:文档现在已更新为0是无效的ID
