First of all I already have an intermediate knowledge about android and I already have some applications in google play.
Recently I was updating the layout of my application, I have a video gallery in my app that whenever I need to delete an item or see the information I used a ContextMenu, but now I replace the ListView with a RecyclerView and wanted to show the menu in a different way, I would like to add a menu button similar to the button that appears on the toolbar when you inflate a menu (Picture below). The problem is that I can not figure out what the button is called, it's probably not an icon added on an image button with the transparent background because this seems to be a native android widget and I could see that it was already present even in the old android summers.
