Question

我想在我的应用程序的android通知栏上显示所选日期和时间的提醒。但即使没有应用程序也应该填充一个。每当我的Android设备启动时，一个选定的时间有/无我的应用程序它应该显示通知在指定时间内如警报。 请帮帮我怎么做？

我找到了一些关于Alarm Manager，Notification manager的链接。 给我一个想法和一些链接，否则样本片段。

Answer 1

public static void notifyIcon(Context context){

NotificationManager notifier = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.your_app_notification, "", System.currentTimeMillis());

/**
*Setting these flags will stop clearing your icon
*from the status bar if the user does clear all 
*notifications.
*/
    notification.flags |= Notification.FLAG_NO_CLEAR | Notification.FLAG_ONGOING_EVENT;
    RemoteViews contentView = new RemoteViews(context.getPackageName(), R.layout.custom_notification_layout);
    notification.contentView = contentView;

//If you want to open any activity on the click of the icon.

    Intent notificationIntent = new Intent(context, YourActivity.class);
    PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);
    notification.contentIntent = contentIntent;

    notification.setLatestEventInfo(context, "title", null, contentIntent);
    notifier.notify(1, notification);

//To cancel the icon ...
    notifier.cancel(1);

}

这是custom_notification_layout.xml

<?xml version = "1.0" encoding = "utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:padding="3dp" >

</LinearLayout>

注意：请勿忘记在适当时清除应用程序图标如果您设置了上面的标记。

使用此按钮添加警报

Intent intent = new Intent(this, TheServiceYouWantToStart.class);
PendingIntent pending = PendingIntent.getService(this, 0, intent, 0);
AlarmManager alarm = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE);
alarm.set(AlarmManager.RTC_WAKEUP, Time_To_wake, pending);
