【问题描述】:
我正在尝试进行预定通知。所有作品除了:当应用程序处于活动状态并最小化时。通知自动启动活动,无需等待用户点击。
回复:
public void onReceive(Context context, Intent paramIntent) {
Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationManager notificationManager = (NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.cancelAll();
Notification notification = new Notification(R.drawable.logo_f, context.getResources().getString(R.string.notification_text), System.currentTimeMillis());
Intent notificationIntent = new Intent(context, TimeLeftActivity.class);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
| Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent intent = PendingIntent.getActivity(context, 0,
notificationIntent, 0);
notification.setLatestEventInfo(context, context.getResources().getString(R.string.notification_text), "", intent);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notification.sound=alarmSound;
// Fire the notification
notificationManager.notify(1, notification);
}
我的通知启动方式:
private void createScheduledNotification(int sec)
{
// Get new calendar object and set the date to now
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
// Add defined amount of days to the date
calendar.add(Calendar.SECOND, sec);
// Retrieve alarm manager from the system
AlarmManager alarmManager = (AlarmManager) getApplicationContext().getSystemService(getBaseContext().ALARM_SERVICE);
// Every scheduled intent needs a different ID, else it is just executed once
int id = 1;
// Prepare the intent which should be launched at the date
Intent intent = new Intent(this, TimeAlarm.class);
// Prepare the pending intent
PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(), id, intent, PendingIntent.FLAG_UPDATE_CURRENT);
alarmManager.cancel(pendingIntent);
// Register the alert in the system. You have the option to define if the device has to wake up on the alert or not
alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);
}
在基里尔回答后编辑。错误仍然存在。通知自动启动挂起的意图并且不等待点击。
@Override
public void onReceive(Context context, Intent paramIntent) {
Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationManager notificationManager = (NotificationManager) context
.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.cancelAll();
Intent notificationIntent = new Intent(context, TimeLeftActivity.class);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
| Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent intent = PendingIntent.getActivity(context, 0,
notificationIntent, 0);
Notification notification = new NotificationCompat.Builder(context)
.setContentTitle(context.getResources().getString(R.string.notification_text))
.setContentIntent(intent)
.setSound(alarmSound)
.build();
notification.flags |= Notification.FLAG_AUTO_CANCEL;
// Fire the notification
notificationManager.notify(1, notification);
}
【问题讨论】:
-
PendingIntent intent = PendingIntent.getActivity(context, 0, notificationIntent, 0);零呢?第二个 0 应该是 PendingIntent 的常量
