推荐答案

可扩展的 Notification 是 Notification

An expandable Notification is a special case of a Notification Big View. If the Big View is not at the top of the notification drawer, it it shown 'closed' and is expandable by swipe. Quote from Android Developers:

仅当扩展通知时才会显示通知的大视图，当通知位于通知抽屉的顶部或用户使用手势扩展通知时会发生.从Android 4.1开始提供扩展的通知.

A notification's big view appears only when the notification is expanded, which happens when the notification is at the top of the notification drawer, or when the user expands the notification with a gesture. Expanded notifications are available starting with Android 4.1.

可以按如下方式创建 Big View Notification :

The Big View Notification can be created as follows:

Notification notification = new Notification.BigTextStyle(builder)
.bigText(myText).build();

或

Notification notification = new Notification.BigPictureStyle(builder)
.bigPicture(
  BitmapFactory.decodeResource(getResources(),
    R.drawable.my_picture)).build();

此处是一个教程.
