Package android.support.v17.leanback.app Description

Support classes providing high level Leanback user interface building blocks: fragments and helpers.

Leanback fragments are available both as platform fragments (subclassed from android.app.Fragment) and as support fragments (subclassed from android.support.v4.app.Fragment). A few of the most commonly used leanback fragments are described here.

A BrowseFragment 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 DetailsFragment 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 BrowseFragment, with the convention that the first element in the ObjectAdapter corresponds to the overview row. The DetailsOverviewRow and DetailsOverviewRowPresenter provide a default template for this row.

A PlaybackOverlayFragment implements standard playback transport controls with a Leanback look and feel. It is recommended to use an instance of the PlaybackControlGlue with the PlaybackOverlayFragment. This helper implements a standard behavior for user interaction with the most commonly used controls such as fast forward and rewind.

A SearchFragment allows the developer to accept a query from a user and display the results using the familiar list rows.

A GuidedStepFragment is used to guide the user through a decision or series of decisions.
