我已经编写了两个通知渠道的代码。但其中一个通知会触发另一个通知,导致两个通知都显示出来。我已经尝试使用pendingIntent
的FLAG_ONE_SHOT
属性,但结果仍然相同。
NotificationHelper
类:
public class NotificationHelper extends ContextWrapper {
public static final String channel1ID = "channel1ID";
public static final String channel1Name = "Add transactions reminder";
public static final String channel2ID = "channel2ID";
public static final String channel2Name = "Due and overdue bills";
private NotificationManager mManager;
public NotificationHelper(Context base) {
super(base);
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O)
createChannels();
}
@RequiresApi(api = Build.VERSION_CODES.O)
public void createChannels() {
NotificationChannel channel1 = new NotificationChannel(channel1ID, channel1Name, NotificationManager.IMPORTANCE_DEFAULT);
channel1.enableLights(true);
channel1.enableVibration(true);
channel1.setLightColor(R.color.colorPrimary);
channel1.setLockscreenVisibility(Notification.VISIBILITY_PRIVATE);
getManager().createNotificationChannel(channel1);
NotificationChannel channel2 = new NotificationChannel(channel2ID, channel2Name, NotificationManager.IMPORTANCE_DEFAULT);
channel2.enableLights(true);
channel2.enableVibration(true);
channel2.setLightColor(R.color.colorPrimary);
channel2.setLockscreenVisibility(Notification.VISIBILITY_PRIVATE);
getManager().createNotificationChannel(channel2);
}
public NotificationManager getManager() {
if (mManager == null) {
mManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
}
return mManager;
}
public NotificationCompat.Builder getChannel1Notification(String title, String message) {
Intent intent = new Intent(getApplicationContext(), MainActivity.class);
int reqCode = (int) System.currentTimeMillis();
PendingIntent pendingIntent = PendingIntent.getActivity(getApplicationContext(), reqCode, intent, PendingIntent.FLAG_UPDATE_CURRENT);
return new NotificationCompat.Builder(getApplicationContext(), channel1ID)
.setContentTitle(title)
.setContentText(message)
.setSmallIcon(R.drawable.ic_notification_icon)
.setAutoCancel(true)
.setContentIntent(pendingIntent);
}
public NotificationCompat.Builder getChannel2Notification(String title, String message) {
Intent intent = new Intent(getApplicationContext(), MainActivity.class);
int reqCode = (int) System.currentTimeMillis();
PendingIntent pendingIntent = PendingIntent.getActivity(getApplicationContext(), reqCode, intent, PendingIntent.FLAG_UPDATE_CURRENT);
return new NotificationCompat.Builder(getApplicationContext(), channel2ID)
.setContentTitle(title)
.setContentText(message)
.setSmallIcon(R.drawable.ic_notification_icon)
.setAutoCancel(true)
.setContentIntent(pendingIntent);
}
}
AlertReceiver
类:
public class AlertReceiver extends BroadcastReceiver {
public static final String TAG = "AlertReceiver";
@Override
public void onReceive(Context context, Intent intent) {
NotificationHelper notificationHelper = new NotificationHelper(context);
//add transactions reminder
NotificationCompat.Builder nb1 = notificationHelper.getChannel1Notification(
notificationHelper.getString(R.string.trans_notify_title), notificationHelper.getString(R.string.notification_msg)
);
notificationHelper.getManager().notify(1, nb1.build());
//due and overdue bills
NotificationCompat.Builder nb2 = notificationHelper.getChannel2Notification(
notificationHelper.getString(R.string.bills_notify_title), notificationHelper.getString(R.string.notification_msg)
);
notificationHelper.getManager().notify(2, nb2.build());
}
}
第一条通知:
public void startAlarm(Calendar c) {
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(this, AlertReceiver.class);
int reqCode = (int) System.currentTimeMillis();
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, reqCode, intent, PendingIntent.FLAG_UPDATE_CURRENT);
alarmManager.setExact(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), pendingIntent);
Toast.makeText(this, getString(R.string.notification_set_at) + timeString + getString(R.string.everydayy), Toast.LENGTH_LONG).show();
}
第二个通知:
private void setNotifications(int dueDayOfYear) {
LocalDate dueDate = LocalDate.ofYearDay(LocalDate.now().getYear(), dueDayOfYear);
LocalDateTime prevDay = dueDate.minusDays(1).atStartOfDay().plusHours(14).plusMinutes(7);
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(context, AlertReceiver.class);
int reqCode = (int) System.currentTimeMillis();
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, reqCode, intent, PendingIntent.FLAG_UPDATE_CURRENT);
alarmManager.setExact(AlarmManager.RTC_WAKEUP, prevDay.atZone(ZoneId.systemDefault()).toInstant().toEpochMilli(), pendingIntent);
}
(plusHours
和plusMinutes
用于测试并确保通知在不同的时间设置)
我认为AlertReceiver
类有问题,但我无法解决它。我该怎么办?
