Normal View Like

Big View - 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 were first introduced in Android 4.1 JellyBean [API 16]. Expandable notifications were designed to support rich notification style objects called Notification.Style.
