在我的应用程序中,我正在尝试设置提醒和闹钟,但我无法做到这一点。由于我不具备如何设置、编辑和删除提醒的完整和正确知识。在Google上搜索后,我得到的结果对我来说难以理解。我尝试了以下代码:Main.java
如何在日历中设置、编辑和删除提醒事项。
谢谢。
Calendar cal = Calendar.getInstance();
java.util.Calendar;
// add minutes to the calendar object
cal.set(Calendar.MONTH, 4);
cal.set(Calendar.YEAR, 2011);
cal.set(Calendar.DAY_OF_MONTH, 5);
cal.set(Calendar.HOUR_OF_DAY, 21);
cal.set(Calendar.MINUTE, 43);
Intent alarmintent = new Intent(getApplicationContext(), AlarmReceiver.class);
alarmintent.putExtra("title","Title of our Notification");
alarmintent.putExtra("note","Description of our Notification");
//HELLO_ID is a static variable that must be initialised at the BEGINNING OF CLASS with 1;
//example:protected static int HELLO_ID =1;
PendingIntent sender = PendingIntent.getBroadcast(getApplicationContext(), HELLO_ID,
alarmintent,PendingIntent.FLAG_UPDATE_CURRENT| Intent.FILL_IN_DATA);
//VERY IMPORTANT TO SET FLAG_UPDATE_CURRENT... this will send correct extra's informations to
//AlarmReceiver Class
// Get the AlarmManager service
AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), sender);
AlarmReceiver.java
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

import android.widget.Toast;
public class AlarmReceiver extends BroadcastReceiver {
private static int NOTIFICATION_ID = 1;
@Override
public void onReceive(Context context, Intent intent) {
NotificationManager manger = (NotificationManager)
context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.icon, "Combi Note", System.currentTimeMillis());
PendingIntent contentIntent = PendingIntent.getActivity(context, NOTIFICATION_ID, new Intent(context, AlarmReceiver.class), 0);
Bundle extras=intent.getExtras();
String title=extras.getString("title");
//here we get the title and description of our Notification
String note=extras.getString("note");
notification.setLatestEventInfo(context, note, title, contentIntent);
notification.flags = Notification.FLAG_INSISTENT;
notification.defaults |= Notification.DEFAULT_SOUND;
//here we set the default sound for our
//notification
// The PendingIntent to launch our activity if the user selects this notification
manger.notify(NOTIFICATION_ID++, notification);
}
}
