Class Overview

An overview Row for a details fragment. This row consists of an image, a description view, and optionally a series of Actions that can be taken for the item.

Actions

Application uses setActionsAdapter(ObjectAdapter) to set actions on the overview row. SparseArrayObjectAdapter is recommended for easily updating actions while maintaining the order. The application can add or remove actions on the UI thread after the row is bound to a view.

Updating main item

After the row is bound to a view, the application may call setItem(Object) on UI thread and the view will be updated.

Updating image

After the row is bound to view, the application may change the image by calling setImageBitmap(Context, Bitmap) or setImageDrawable(Drawable) on the UI thread, and the view will be updated.
