Android Tv - Losing Focus in Details Fragment

问题:

I am developing a Android Tv application using lean-back library. I am losing focus when pressing down in DPAD. Description is not seeing completely. First Focus going to Action Row and then navigate to the last Row . How to give focus to the description ? I am using FullWidthDetailsOverviewRowPresenter and DetailsDescriptionPresenter for the Details page.

you should use FullWidthDetailsOverviewSharedElementHelper and assign it as listener to FullWidthDetailsOverviewRowPresenter . The trick is to change focus by changing the position of the thumbnail image in details view.
