 1 | # RecyclerView-ConcatAdapter
 2 | 
 3 | The main goal is to practice [RecyclerView ConcatAdapter](https://developer.android.com/jetpack/androidx/releases/recyclerview#version_120_2) 
 4 | a new RecyclerView Adapter that can combine multiple adapters linearly.
 5 | 
 6 | Read more about [Concatenate adapters sequentially with ConcatAdapter](https://medium.com/androiddevelopers/merge-adapters-sequentially-with-mergeadapter-294d2942127a) by Florina Muntenescu.

 8 | ## Sample
 9 | 
10 | **LinearLayoutManager (Vertical)**
11 | 
12 | <img src="./art/Screenshot.png" width="220">
13 | 
14 | ```xml
15 | 
16 |     <androidx.recyclerview.widget.RecyclerView
17 |         ...
18 |         app:spanCount="2"
19 |         app:layoutManager="androidx.recyclerview.widget.GridLayoutManager"/>
20 | 
21 | ```
22 | 
23 |  
24 | Try adding horizontal orientation `android:orientation="horizontal"` to GridLayoutManager or LinearLayoutManager.
