I mimic the Google Now card style, and now I want to have the three-dot menu on each card to display further advanced options that are possible with this list item.
Unfortunately, I have no idea how they made it. It seems similar to the onOptionsItemSelected.
Any ideas?
I would suggest you use this CardLib project: https://github.com/gabrielemariotti/cardslib
It's pretty comprehensive in providing card themed UI with nearly all the features one would need.
