FanMenu

A simple widget that can be used to display menu’s which can be animated in and out. The menu’s can be animated in from behind a button like a FloatingActionButton to give an effect of a submenu or can be placed on the screen to work as menus.

Features

  • Show as many menu items as you like, with or without icons.
  • Icons can be changed when selected.
  • Colors, text and icons can be specified in the xml.
  • If a background color is set, this fades in/out when the menu opens/closes.
  • The menu can be movable or fixed.
  • Menu can reset if moved beyond a certain boundary.

Adding it to your project

compile 'com.bcgdv.asia.lib:fanmenu:1.1'

The menus needs to be configured in the XML.
