CardBuilder

Added in API level XE21

The CardBuilder class helps with building Glass-themed cards with various layouts.

See Creating Glass-styled cards for more information and sample code.

General usage

1. Create a CardBuilder object, passing the desired CardBuilder.Layout to the constructor.
2. Set content on the card with the add/set* family of methods.
3. Get the View by calling getView() or get a RemoteViews object with getRemoteViews().

Recycling note for embedded layouts

When using EMBED_INSIDE CardBuilder makes no distinction between different embedded layouts when recycling views. If you have two CardBuilder instances with EMBED_INSIDE but one has layout A and the other has layout B, they will be treated as the same by CardBuilder.

If this behavior is undesirable (for example, when using a CardScrollAdapter with different embedded layouts), you must distinguish them by returning different view types from getItemViewType(int) so that the recycler only sends you convertViews with nested layouts that you expect for a particular item.

If you need to support cards with multiple embedded layouts alongside the built-in layouts, we recommend that you return view types numbered getViewTypeCount(), CardBuilder.getViewTypeCount() + 1, and so on.

Nested Classes
enum	CardBuilder.Layout		Defines the visual layouts for cards.

Parameters

imageDrawable	the Drawable image to add

Returns

• this object for call chaining

Added in API level XE21

public CardBuilder addImage (Bitmap imageBitmap)

Adds an image, specified as a Bitmap, to the card.

Parameters

imageBitmap	the Bitmap image to add
