RecyclerViewHelpper

![Bintray](http://i.imgur.com/ohkyaD6.png)

Android library project that intends to simplify the usage of Adapters for ListView/GridView and RecyclerView. You won't have to code any boring adapter again!

It helps to keep boilerplate to a minimum and adds the possibility of easily changing between BaseAdapter / RecyclerView.Adapter adapter styles without changing any code. It also allows painless usage of multiple models / view types for the same list or grid
## Feature ##
- adapter for RecyclerView & AdapterView

- height WRAP-CONTENT for RecyclerView(LinearLayout & GirdLayout)

- CommonItemDecoration for RecyclerView

----------
## Adding to your project ##

Add this to your dependencies:

compile 'com.hadlink:rvhelpperlib:1.0.3'
