android.support.v17.leanback.app
Support classes providing high level Leanback user interface building blocks.
Leanback fragments are available both as support fragments (subclassed from
android.support.v4.app.Fragment) and as platform
fragments (subclassed from android.app.Fragment). A few of the most
commonly used leanback fragments are described here.
A BrowseSupportFragment by default operates in the "row"
mode. It includes an optional “fastlane”
navigation side panel and a list of rows, with one-to-one correspondance between each header
in the fastlane and a row. The application supplies the
ObjectAdapter containing the list of
rows and a PresenterSelector of row presenters.
A BrowseSupportFragment also works in a "page" mode when
each row of fastlane is mapped to a fragment that the app registers in
getMainFragmentRegistry().
A DetailsSupportFragment will typically consist of a
large overview of an item at the top,
some actions that a user can perform, and possibly rows of additional or related items.
The content for this fragment is specified in the same way as for the BrowseSupportFragment, with
the convention that the first element in the ObjectAdapter corresponds to the overview row.
The DetailsOverviewRow and
FullWidthDetailsOverviewRowPresenter provide a
default template for this row.
A PlaybackSupportFragment or its subclass
VideoSupportFragment hosts
PlaybackTransportControlGlue
or PlaybackBannerControlGlue with a Leanback
look and feel. It is recommended to use an instance of
PlaybackTransportControlGlue.
This helper implements a standard behavior for user interaction with
the most commonly used controls as well as video scrubbing.
A SearchSupportFragment allows the developer to accept a
query from a user and display the results
using the familiar list rows.
A GuidedStepSupportFragment is used to guide the user
through a decision or series of decisions.
