---

A subclass of BaseCardView with an ImageView as its main region. The ImageCardView is highly customizable and can be used for various use-cases by adjusting the ImageViewCard's type to any combination of Title, Content, Badge or ImageOnly.

Styling

There are two different ways to style the ImageCardView.
No matter what way you use, all your styles applied to an ImageCardView have to extend the style Widget_Leanback_ImageCardViewStyle.

Example:

 <style name="CustomImageCardViewStyle" parent="Widget.Leanback.ImageCardViewStyle">
        <item name="cardBackground">#F0F</item>
        <item name="lbImageCardViewType">Title|Content</item>
   </style>
   <style name="CustomImageCardTheme" parent="Theme.Leanback">
        <item name="imageCardViewStyle">@style/CustomImageCardViewStyle</item>
        <item name="imageCardViewInfoAreaStyle">@style/ImageCardViewColoredInfoArea</item>
        <item name="imageCardViewTitleStyle">@style/ImageCardViewColoredTitle</item>
    </style>
 

The first possibility is to set custom Styles in the Leanback Theme's attributes imageCardViewStyle, imageCardViewTitleStyle etc. The styles set here, is the default style for all ImageCardViews.

The second possibility allows you to style a particular ImageCardView. This is useful if you want to create multiple types of cards. E.g. you might want to display a card with only a title and another one with title and content. Thus you need to define two different ImageCardViewStyles and two different themes and apply them to the ImageCardViews. You can do this by using a the ImageCardView(Context) constructor and passing a ContextThemeWrapper with the custom ImageCardView theme id.

Example (using constructor):

 new ImageCardView(new ContextThemeWrapper(context, R.style.CustomImageCardTheme));
 
 

You can style all ImageCardView's components such as the title, content, badge, infoArea and the image itself by extending the corresponding style and overriding the specific attribute in your custom ImageCardView theme.

Components

The ImageCardView contains three components which can be combined in any combination:

• Title: The card's title
• Content: A short description
• Badge: An icon which can be displayed on the right or left side of the card.

In order to choose the components you want to use in your ImageCardView, you have to specify them in the lbImageCardViewType attribute of your custom ImageCardViewStyle. You can combine the following values: Title, Content, IconOnRight, IconOnLeft, ImageOnly.

Examples:

 <style name="CustomImageCardViewStyle" parent="Widget.Leanback.ImageCardViewStyle">
        ...
        <item name="lbImageCardViewType">Title|Content|IconOnLeft</item>
        ...
    </style>
 

 <style name="CustomImageCardViewStyle" parent="Widget.Leanback.ImageCardViewStyle">
        ...
        <item name="lbImageCardViewType">ImageOnly</item>
        ...
    </style>
