Sie können DatePicker verwenden, um Datum vom Benutzer zu nehmen. Verwenden Sie den Alarm-Manager, um den eingestellten Alarm einzustellen, und erstellen Sie dann eine onReceive-Methode, um eine Benachrichtigung zu erstellen.
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent notificationIntent = new Intent("android.media.action.DISPLAY_NOTIFICATION");
notificationIntent.addCategory("android.intent.category.DEFAULT");
PendingIntent broadcast = PendingIntent.getBroadcast(this, 100, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
Calendar cal = Calendar.getInstance();
cal.add(Calendar.DATE, d); // Date for your notification
cal.add(Calendar.MONTH, m); // Date for your notification
cal.add(Calendar.YEAR, y); // Date for your notification
alarmManager.setExact(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), broadcast);

<intent-filter>
<action android:name="android.media.action.DISPLAY_NOTIFICATION" />
<category android:name="android.intent.category.DEFAULT" />

public class AlarmReceiver extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent intent) {
Intent notificationIntent = new Intent(context, NotificationActivity.class);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
stackBuilder.addParentStack(NotificationActivity.class);
stackBuilder.addNextIntent(notificationIntent);
PendingIntent pendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
Notification notification = builder.setContentTitle("Demo App Notification")
.setContentText("New Notification From Demo App..")
.setTicker("New Message Alert!")
.setSmallIcon(R.mipmap.ic_launcher)
.setContentIntent(pendingIntent).build();
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
