I wonder if its possible to use a BrowseFragment with another Layer/Level of Rows. something like
cat1 - row1 -> item1 -> subrow1
cat2 - row2 -> item1 -> subrow2
and so on. Is there something i can do with a BrowseFragment and the Adapter to get that hierarchy or should i implement it myself?
And how could i implement that myself? i would spawn another Activity with a VerticalRowFragment but thats not exactly the same.
Any hints or tipps are welcome.
Yes, it is possible. Take a look at this answer. I'm trying to finish the second part of the tutorial series, that explains (and shows the code) that does exactly that.
If you want to see an example (and you have a Nexus Player / ADT-1), please check out the musixmatch application. It is build using that exact same technique.
EDIT
Here's the article! It's part of a bigger collection, if you want to have a look.
