当开发者想要在不需要用户在他们的手机上打开app的情况下,还可以允许表达更多的信息,那么开发者可以在可穿戴设备上的Notification中添加一个或多个的页面。添加的页面会马上出现在主 Notification 卡片的右边。
为了创建一个拥有多个页面的 Notification,开发者需要:
举个例子,以下代码为Notification添加了第二个页面:
// Create builder for the main notification
NotificationCompat.Builder notificationBuilder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.new_message)
.setContentTitle("Page 1")
.setContentText("Short message")
.setContentIntent(viewPendingIntent);
// Create a big text style for the second page
BigTextStyle secondPageStyle = new NotificationCompat.BigTextStyle();
secondPageStyle.setBigContentTitle("Page 2")
.bigText("A lot of text...");
// Create second page notification
Notification secondPageNotification =
new NotificationCompat.Builder(this)
.setStyle(secondPageStyle)
.build();
// Add second page with wearable extender and extend the main notification
Notification twoPageNotification =
new WearableExtender()
.addPage(secondPageNotification)
.extend(notificationBuilder)
.build();
// Issue the notification
notificationManager =
NotificationManagerCompat.from(this);
notificationManager.notify(notificationId, twoPageNotification);
