Step 5: Provide the Details of the App Content Through the DetailsFragment (Fire TV)
Learn how to provide information about a specific piece of content. To do this, we'll use one of the main components of a Leanback-enabled project: the DetailsFragment.
The DetailsFragment
The DetailsFragment
is displayed when the user selects a specific piece of content on the BrowseFragment
. It contains information like title, subtitle, and description, and is accompanied by a preview of the content.
One of the most important classes used in the DetailsFragment
is DetailsOverViewRow
. This class defines which content is displayed in the fragment and, most importantly, is responsible for defining the actions that we can prompt our user to perform.
private void setupDetailsOverviewRow() {
final DetailsOverviewRow row
= new DetailsOverviewRow(mSelectedMovie);
...
row.setImageDrawable(R.drawable.default_background));
row.addAction(new Action(ACTION_WATCH_TRAILER,
"Watch Trailer", "FREE")));
mAdapter.add(row);
}
The highlighted row below highlights how easy it is to add a specific action to the DetailsFragment
. Just by coding addAction()
, we can add a new action for the user to perform. In this case, we added the unique ID ACTION_WATCH_TRAILER
, for the action and two strings, Watch Trailer
and FREE
, to define the text field of the button.
Once we have added this line, the action will be displayed on the DetailsFragment
.
By using actions, we can easily add IAP items like "Rent the Content," "Buy," or "Subscribe;" it's just a matter of attaching a Listener to the actions to perform consequent tasks.
When we deploy a Leanback-enabled project, the only action that is defined by default is "Watch Trailer," which prompts the trailer of the content to play.
