이것은 아래 코드입니다. 알림 채널을 만들려고하면 Android O에서 알림을 만들 수 없습니다. 이 관리자에 알림을 구축하여 다음 알림 관리자를 사용하여 알림 채널을 만들기 -채널 생성에도 불구하고 Android O에 알림이 표시되지 않습니다.
private void weatherNotification(WeatherInfo weather) {
Intent intent = new Intent(this, WeatherActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);
String temperatureScale = prefs.getUnits().equals("metric") ? getString(R.string.c) : getString(R.string.f);
String speedScale = prefs.getUnits().equals("metric") ? getString(R.string.mps) : getString(R.string.mph);
String temperature = getString(R.string.temperature , weather.getMain().getTemp() , temperatureScale);
String city = getString(R.string.city , weather.getName() + ", " + weather.getSys().getCountry());
String wind = getString(R.string.wind_ , weather.getWind().getSpeed(), speedScale);
String humidity = getString(R.string.humidity , weather.getMain().getHumidity());
String pressure = getString(R.string.pressure, weather.getMain().getPressure());
String data = city + "\n" + temperature + "\n" + wind + "\n" + humidity + "\n" + pressure;
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
String id = "w01", name = getString(R.string.weather_notification_title);
int importance = NotificationManager.IMPORTANCE_DEFAULT;
String desc = getString(R.string.weather_notification_description);
NotificationChannel channel = new NotificationChannel(id, name, importance);
channel.setDescription(desc);
notificationManager.createNotificationChannel(channel);
}
Notification.Builder builder = new Notification.Builder(this);
builder.setAutoCancel(false);
builder.setContentTitle("Weather Notification");
builder.setContentText(Math.round(weather.getMain().getTemp()) + temperatureScale + " at " + weather.getName());
builder.setStyle(new Notification.BigTextStyle().bigText(data));
builder.setSmallIcon(R.drawable.ic_notification_icon);
builder.setContentIntent(pendingIntent);
if (Build.VERSION.SDK_INT >= 24)
builder.setColor(Color.parseColor("#ff0000"));
Notification notification = builder.build();
notificationManager.notify(0 , notification);
}
는 내가 안드로이드 O에 통지를 생성에 필요한 모든 단계를 따라했습니다 믿습니다. 내가 어디로 잘못 가고 있는지 모르겠다.
편집 1 : weatherNotification에서 다음과 같이 변경() 메소드를 제작은 여전히 작동하지 않습니다
private void weatherNotification(WeatherInfo weather) {
....
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
String id = "w01", name = getString(R.string.weather_notification_title);
int importance = NotificationManager.IMPORTANCE_DEFAULT;
String desc = getString(R.string.weather_notification_description);
NotificationChannel channel = new NotificationChannel(id, name, importance);
channel.setDescription(desc);
notificationManager.createNotificationChannel(channel);
builder = new Notification.Builder(this , id);
}
builder = new Notification.Builder(this);
builder.setAutoCancel(false);
builder.setContentTitle("Weather Notification");
builder.setContentText(Math.round(weather.getMain().getTemp()) + temperatureScale + " at " + weather.getName());
builder.setStyle(new Notification.BigTextStyle().bigText(data));
builder.setSmallIcon(R.drawable.ic_notification_icon);
builder.setContentIntent(pendingIntent);
if (Build.VERSION.SDK_INT >= 24)
builder.setColor(Color.parseColor("#ff0000"));
Notification notification = builder.build();
notificationManager.notify(0 , notification);
....
}
편집 2 : 편집 한 코드에서, 나는 빌더가 다시 재생되고있는 것을 발견했다. 그래서 나는 다시 다음과 같이 변경했다 :
private void weatherNotification(WeatherInfo weather) {
....
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
String id = "w01", name = getString(R.string.weather_notification_title);
int importance = NotificationManager.IMPORTANCE_DEFAULT;
String desc = getString(R.string.weather_notification_description);
NotificationChannel channel = new NotificationChannel(id, name, importance);
channel.setDescription(desc);
notificationManager.createNotificationChannel(channel);
builder = new Notification.Builder(this , id);
}
else
builder = new Notification.Builder(this);
....
}
확인하십시오. EDIT 1 – Sparker0i
EDIT 2, 작동했습니다. 감사합니다. – Sparker0i
