android - How to implement more than 2 level navigation in com.android.support:leanback-v17

Question

In regular android application I can use navigation drawer for navigate between top level views (sections of app) What should be used in tv apps? I see only possibility for two level of content organizing Categories -> Movies But in our app we have several sections (Live channels, On demand Movies, Recorded shows etc) with categories in most of them. Is it possible using standard android.support.v17.leanback.app.BrowseFragment and android.support.v17.leanback.app.DetailsFragment?

Answer 1

简而言之：没有。BrowseFragment并且DetailsFragment旨在成为开发人员将其内容带到电视上的一种快速简便的方法。它们迫使您使用那种非常容易理解和导航的特定结构。

如果您愿意全力以赴获得定制体验，则需要BrowseFragment使用 aHeadersFragment和 a构建您的RowsFragment. 事实证明这很令人头疼，但我设法为我公司的应用程序做到了。如果你有兴趣，我会写一篇关于这个的帖子/文章。
