Java 为什么在设置通知时间的同时会引发通知？

我使用时间选择器设置用户通知的时间。我使用过报警管理器和通知生成器

我已经在按钮的clickListener上调用了setAlarm方法来保存数据。因此，当调用此setAlarm方法时，通知将在用户设置的时间同时发出

我不希望在保存数据时引发它

谁能告诉我为什么会这样

设置报警方法

@SuppressLint("NewApi")
private void setAlarm(Calendar targetmCalen) {

    AlarmManager alarmMgr;
    PendingIntent alarmIntent;
    alarmMgr = (AlarmManager)getApplicationContext().getSystemService(Context.ALARM_SERVICE);
    Intent intent = new Intent(getApplicationContext(), NotificationReceiver.class);
    alarmIntent = PendingIntent.getBroadcast(getApplicationContext(), 0, intent, 0);
    Toast.makeText(getBaseContext(),
            "call alarmManager.setExact()",
            Toast.LENGTH_LONG).show();

    intent.putExtra("title",eventTitle);


    alarmMgr.setInexactRepeating(AlarmManager.RTC_WAKEUP, targetmCalen.getTimeInMillis(),
            AlarmManager.INTERVAL_DAY, alarmIntent);

    ComponentName receiver = new ComponentName(getApplicationContext(),NotificationReceiver.class);
    PackageManager pm = getApplicationContext().getPackageManager();

    pm.setComponentEnabledSetting(receiver,
            PackageManager.COMPONENT_ENABLED_STATE_ENABLED,
            PackageManager.DONT_KILL_APP);

}

通知接收者

public class NotificationReceiver  extends BroadcastReceiver {


    private static final int MY_NOTIFICATION_ID = 0;
    NotificationManager notificationManager;
    Notification myNotification;

    EventTableHelper db;

    @Override
    public void onReceive(Context context, Intent intent) {


        Toast.makeText(context, "Time is set", Toast.LENGTH_LONG).show();

        db = new EventTableHelper(context);

        List<EventData> testSavings = db.getAllEvents();

        for (EventData ts : testSavings) {
            String log = "from date:" + ts.getFromDate()
                    + " ,to date: " + ts.getToDate()
                    + " ,location: " + ts.getLocation()
                    + " ,title " + ts.getTitle();

            Date date = new Date();
            Date date1 = new Date();
            Log.d("Result: ", log);

            SimpleDateFormat df = new SimpleDateFormat("E MMM dd HH:mm:ss zzzz yyyy");
            SimpleDateFormat df2 = new SimpleDateFormat("HH:mm a");

            try {
                date = df.parse(ts.getFromDate());
                date1 = df.parse(ts.getToDate());
            } catch (ParseException ex) {

            }
            String timeFrom = df2.format(date);
            String startTime = String.valueOf(timeFrom);

            String timeTo = df2.format(date1);
            String endTime = String.valueOf(timeTo);


            String location = ts.getLocation();

谢谢。

如果您在设置报警时报警，则表示您在过去给了它一个日期/时间。否。我没有。每当我点击save（保存）按钮时，就会触发警报。请检查编辑后的问题：@Mike MJust现在我已经添加了，在添加星期几之前，问题是相同的。“减去星期几做什么？”-我的意思是删除该行。这导致当天被重置为本月的第一个星期一，也就是两天前。“在事件发生10分钟前报警怎么样？”-在您尝试创建复杂的时间表之前，您应该先让一个简单的报警生效。
