如何在Android中设置提醒？

Question

我正在尝试为Android构建日历应用。我被打中间了。我已设法从用户检索时间和任务等信息。我不知道如何将其添加到android事件中。有类似的setEvent东西吗？

您可以在带有通知机制的coop中使用AlarmManager，如下所示：

Intent intent = new Intent(ctx, ReminderBroadcastReceiver.class);

PendingIntent pendingIntent = PendingIntent.getBroadcast(ctx, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

AlarmManager am = (AlarmManager) ctx.getSystemService(Activity.ALARM_SERVICE);

// time of of next reminder. Unix time.

long timeMs =...

if (Build.VERSION.SDK_INT < 19) {

    am.set(AlarmManager.RTC_WAKEUP, timeMs, pendingIntent);

} else {

    am.setExact(AlarmManager.RTC_WAKEUP, timeMs, pendingIntent);

}

它开始报警。

public class ReminderBroadcastReceiver extends BroadcastReceiver {

    @Override

    public void onReceive(Context context, Intent intent) {

        NotificationCompat.Builder builder = new NotificationCompat.Builder(context)

                .setSmallIcon(...)

                .setContentTitle(..)

                .setContentText(..);

        Intent intentToFire = new Intent(context, Activity.class);

        PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intentToFire, PendingIntent.FLAG_UPDATE_CURRENT);

        builder.setContentIntent(pendingIntent);

        NotificationManagerCompat.from(this);.notify((int) System.currentTimeMillis(), builder.build());

    }

}
