DetailsOverviewRow

Kotlin |Java

open class DetailsOverviewRow : Row

kotlin.Any
↳	androidx.leanback.widget.Row
	↳	androidx.leanback.widget.DetailsOverviewRow

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 or setImageDrawable(Drawable) on the UI thread, and the view will be updated.

Inherited functions

From class Row

`HeaderItem!`	`getHeaderItem()` Returns the `HeaderItem` that represents metadata for the row.
`Long`	`getId()` Returns a unique identifier for this row. This id can come from one of three places: If `setId(long)` is ever called on this row, it will return this id. If `setId(long)` has not been called but the header item is not null, the result of `HeaderItem#getId()` is returned. Otherwise `NO_ID` is returned.
`Boolean`	`isRenderedAsRowView()` Returns true if this Row can be rendered in a visible row view, false otherwise. For example `ListRow` is rendered by `ListRowPresenter`. `PageRow`, `SectionRow`, `DividerRow` are rendered as invisible row views.

`Unit`	`setId(id: Long)` Sets the id for this row.
