# android.support.v17.leanback.widget added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) # android.support.v17.leanback.widget | This package is part of the Android[support library](https://developer.android.com/topic/libraries/support-library)which is no longer maintained. The support library has been superseded by[AndroidX](https://developer.android.com/jetpack/androidx)which is part of[Jetpack](https://developer.android.com/jetpack). We recommend using the AndroidX libraries in all new projects. You should also consider[migrating](https://developer.android.com/jetpack/androidx/migrate)existing projects to AndroidX. To find the AndroidX class that maps to this deprecated class, see the AndroidX support library[class mappings](https://developer.android.com/jetpack/androidx/migrate/class-mappings). Support classes providing low level Leanback user interface building blocks: widgets and helpers. The core interface to the developer's model is the[ObjectAdapter](https://developer.android.com/reference/android/support/v17/leanback/widget/ObjectAdapter). It is similar to Adapter and the RecyclerView Adapter, but separates iterating items from presenting them as Views. Concrete implementations include[ArrayObjectAdapter](https://developer.android.com/reference/android/support/v17/leanback/widget/ArrayObjectAdapter)and[CursorObjectAdapter](https://developer.android.com/reference/android/support/v17/leanback/widget/CursorObjectAdapter), but a developer is free to use a subclass of an ObjectAdapter to iterate over any existing Object hierarchy. A[Presenter](https://developer.android.com/reference/android/support/v17/leanback/widget/Presenter)creates Views and binds data from an Object to those Views. This is the complementary piece to ObjectAdapter that corresponds to existing Android adapter classes. The benefit to separating out a Presenter is that we can use it to generate Views outside of the context of an adapter. For example, a UI may represent data from a single Object in several places at once. Each View that needs to be generated can be produced by a different Presenter, while the Object is retrieved from the ObjectAdapter once. A[PresenterSelector](https://developer.android.com/reference/android/support/v17/leanback/widget/PresenterSelector)determines which Presenter to use for a given Object from an ObjectAdapter. Two common cases are when an ObjectAdapter uses the same View type for every element ([SinglePresenterSelector](https://developer.android.com/reference/android/support/v17/leanback/widget/SinglePresenterSelector)), and when the Presenter is determined by the Java class of the element ([ClassPresenterSelector](https://developer.android.com/reference/android/support/v17/leanback/widget/ClassPresenterSelector)). A developer is able to implement any selection logic as a PresenterSelector. For example, if all the elements of an ObjectAdapter have the same type, but certain elements are to be rendered using a 'promotional content' view in the developer's application, the PresenterSelector may inspect the fields of each element before choosing the appropriate Presenter.
The basic navigation model for Leanback is that of a vertical list of rows, each of which may be a horizontal list of items. Therefore, Leanback uses ObjectAdapters both for defining the horizontal data items as well as the list of rows themselves. Leanback defines a few basic data model classes for rows: the[Row](https://developer.android.com/reference/android/support/v17/leanback/widget/Row), which defines the abstract concept of a row with a header; and[ListRow](https://developer.android.com/reference/android/support/v17/leanback/widget/ListRow), a concrete Row implementation that uses an ObjectAdapter to present a horizontal list of items. The corresponding presenter for the ListRow is the[ListRowPresenter](https://developer.android.com/reference/android/support/v17/leanback/widget/ListRowPresenter). Other types of Rows and corresponding RowPresenters are provided; however the application may define a custom subclass of[Row](https://developer.android.com/reference/android/support/v17/leanback/widget/Row)and[RowPresenter](https://developer.android.com/reference/android/support/v17/leanback/widget/RowPresenter). ##
