use[RowsSupportFragment](https://developer.android.com/reference/android/support/v17/leanback/app/RowsSupportFragment)
An ordered set of rows of leanback widgets.
A RowsFragment renders the elements of its[ObjectAdapter](https://developer.android.com/reference/android/support/v17/leanback/widget/ObjectAdapter)as a set of rows in a vertical list. The Adapter's[PresenterSelector](https://developer.android.com/reference/android/support/v17/leanback/widget/PresenterSelector)must maintain subclasses of[RowPresenter](https://developer.android.com/reference/android/support/v17/leanback/widget/RowPresenter).
