java - 每天特定时间通知不通知

Question

我想每天上午 8:00 生成通知。我已经创建了简单通知的代码，但没有收到通知，以下是 NotifyService 类的代码

    public class NotifyService extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    /*Notification Related*/
        NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(this)
                        .setSmallIcon(R.drawable.notification_icon)
                        .setContentTitle("Thought")
                        .setContentText("Get Today's Thought");
        Intent resultIntent = new Intent(this, MainActivity.class);
        PendingIntent resultPendingIntent =
                PendingIntent.getActivity(this, 0, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);
        mBuilder.setContentIntent(resultPendingIntent);
        //mBuilder.setAutoCancel(true);

        // Sets an ID for the notification
        int mNotificationId = 001;
        // Gets an instance of the NotificationManager service
        NotificationManager mNotifyMgr =
                (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        // Builds the notification and issues it.
        mNotifyMgr.notify(mNotificationId, mBuilder.build());
    }
}

这是MainActivity类onCreate方法中编写的代码

PendingIntent pendingIntent;
    Intent myIntent = new Intent(this , NotifyService.class);
    AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
    pendingIntent = PendingIntent.getService(this, 0, myIntent, 0);
    Calendar calendar1 = Calendar.getInstance();
    calendar1.set(Calendar.HOUR_OF_DAY,8);
    calendar1.set(Calendar.MINUTE,00);
    calendar1.set(Calendar.SECOND,00);
    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 24 * 60 * 60 * 1000, pendingIntent);

不知道哪里错了

我认为您没有在这里创建服务。 Notifyservice 类扩展了 AppCompatActivity。您应该扩展 Service 类以使其成为一项服务。
