我将使用AlarmManager来在事件日期和时间显示通知。但是,当事件更新时,我应该如何更新AlarmManager发送PendingIntent到我的应用程序的时间呢?
当创建事件时,将调用以下代码:
缩进被称为 TimerReciver:
当创建事件时,将调用以下代码:
public void setOneTimeAlarm() {
Intent intent = new Intent(this, TimerReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0,
intent, PendingIntent.FLAG_ONE_SHOT);
Calendar c = Calendar.getInstance();
c.set(Calendar.YEAR, year);
c.set(Calendar.MONTH, month);
c.set(Calendar.DAY_OF_MONTH, day-1);
c.set(Calendar.HOUR_OF_DAY, 18);
c.set(Calendar.MINUTE, 00);
long date = c.getTimeInMillis();
mAlarmManager.set(AlarmManager.RTC_WAKEUP, date, pendingIntent);
}
缩进被称为 TimerReciver:
@Override
public void onReceive(Context context, Intent intent) {
Log.v("TimerReceiver", "onReceive called!");
Intent notificationIntent = new Intent(context, ListTests.class);
PendingIntent contentIntent = PendingIntent.getActivity(context,
123, notificationIntent,
PendingIntent.FLAG_CANCEL_CURRENT);
NotificationManager nm = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
Resources res = context.getResources();
NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
long[] pattern = {0,300};
builder.setContentIntent(contentIntent)
.setSmallIcon(R.drawable.ic_launcher)
.setLargeIcon(BitmapFactory.decodeResource(res, R.drawable.ic_launcher))
.setTicker(res.getString(R.string.app_name))
.setWhen(System.currentTimeMillis())
.setAutoCancel(true)
.setVibrate(pattern)
.setContentTitle(res.getString(R.string.notification_title))
.setContentText(res.getString(R.string.notification_text));
Notification n = builder.build();
nm.notify(789, n);
}
