自定义通知最大高度？

Question

我正在尝试进行自定义通知，并且它总是变得非常小（大多数通知的大小）。我可以看到Netflix和Youtube在投射到Chromecast设备时显示更大的通知，这些通知看起来很自定义（它们可能是大视图）。他们如何让他们成为那么大？

谢谢。

的你似乎已经知道了......你可能会谈论大视图样式的通知。谷歌有specific training documentation以及a technical guide。下面是一些示例代码：

// Constructs the Builder object. 
NotificationCompat.Builder builder = 
     new NotificationCompat.Builder(this) 
     .setSmallIcon(R.drawable.ic_stat_notification) 
     .setContentTitle(getString(R.string.notification)) 
     .setContentText(getString(R.string.ping)) 
     .setDefaults(Notification.DEFAULT_ALL) // requires VIBRATE permission 
     /* 
     * Sets the big view "big text" style and supplies the 
     * text (the user's reminder message) that will be displayed 
     * in the detail area of the expanded notification. 
     * These calls are ignored by the support library for 
     * pre-4.1 devices. 
     */ 
     .setStyle(new NotificationCompat.BigTextStyle() 
       .bigText(msg)) 
     .addAction (R.drawable.ic_stat_dismiss, 
       getString(R.string.dismiss), piDismiss) 
     .addAction (R.drawable.ic_stat_snooze, 
       getString(R.string.snooze), piSnooze); 

请注意拨打setStyle。
