Android:如何创建一个提醒，如谷歌保持提醒

Question

我想在我的安卓应用程序中添加一个提醒，比如谷歌保持应用程序提醒笔记，就像你在“每日邮报”中所知道的那样，你可以在设定的日期(今天，明天，第二天或者从日历中选择一个日期)和设定的时间(早上、下午、晚上、夜晚或从时钟中挑选一个时间)来设置提醒。有什么帮助吗？

我找到答案了！并与你们分享，因为我认为这与机械土耳其人无关)。在MainActivity中：

final AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
final Intent intentAlarm = new Intent(MainActivity.this, AlarmReceiver.class);
Calendar calendar =  Calendar.getInstance();   
calendar.set(Calendar.SECOND, 0);
calendar.set(Calendar.MINUTE, 22);
calendar.set(Calendar.HOUR, 5);
calendar.set(Calendar.AM_PM, Calendar.PM);
calendar.set(Calendar.MONTH, 0);
calendar.set(Calendar.DAY_OF_MONTH, 6);
calendar.set(Calendar.YEAR,2015);
long when = calendar.getTimeInMillis();
alarmManager.set(AlarmManager.RTC_WAKEUP,when, PendingIntent.getBroadcast(MainActivity.this,1,  intentAlarm, PendingIntent.FLAG_UPDATE_CURRENT));

AlarmReciver类：

public class AlarmReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Calendar now = GregorianCalendar.getInstance();
            Notification.Builder mBuilder = 
                    new Notification.Builder(context)
                    .setSound(android.provider.Settings.System.DEFAULT_NOTIFICATION_URI)
                    .setSmallIcon(R.drawable.ic_launcher)
                    .setContentTitle("my title")
                    .setContentText("my text");             
            Intent resultIntent = new Intent(context, MainActivity.class);
            TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
            stackBuilder.addParentStack(MainActivity.class);
            stackBuilder.addNextIntent(resultIntent);
            PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
            mBuilder.setContentIntent(resultPendingIntent);
            NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
            mNotificationManager.notify(1, mBuilder.build());
    }
}

并取消提醒：

if (alarmManager!= null) {
                alarmManager.cancel(PendingIntent.getBroadcast(MainActivity.this,1,  intentAlarm, PendingIntent.FLAG_UPDATE_CURRENT));
            }
