java - 设置特定日期的通知( fragment )

Question

我正在尝试在特定日期和时间弹出通知。变量很好，我已经测试过了。这是对我不起作用的代码。

Intent intent = new Intent(getActivity(), NotificationPublisher.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(getActivity(), 001, intent, 0);

AlarmManager am = (AlarmManager)getActivity().getSystemService(ALARM_SERVICE);
am.set(AlarmManager.RTC_WAKEUP, reminder.getTimeInMillis(), pendingIntent);

什么也没发生。完全没有。我不明白为什么。这是我从谷歌上出现的第一篇文章中得到的代码。我更改任何内容的唯一原因是因为我正在 fragment 内工作。

Calendar sevendayalarm = Calendar.getInstance();

sevendayalarm.add(Calendar.DATE, 7);

Intent intent = new Intent(this, Receiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 001, intent, 0);

AlarmManager am = (AlarmManager)getSystemService(ALARM_SERVICE);
am.set(AlarmManager.RTC_WAKEUP, sevendayalarm.getTimeInMillis(), pendingIntent);

我将以文本形式添加我的 list 和NotificationPublisher.java 文件。希望有人能找出问题所在......

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />

<service android:name=".NotficationPublisher" android:enabled="true">
    <intent-filter> <action android:name="NOTIFICATION_SERVICE" /></intent-filter>
</service>

Answer 1

您需要更改此设置:

PendingIntent.getBroadcast(getActivity(), 001, intent, 0);

至

PendingIntent.getService(getActivity(), 001, intent, 0);

因为您的 NotificationPublisher 是一个 Service 而不是 BroadcastReceiver。
