# AdapterLayout
2+
ViewGroup backed by RecyclerView.Adapter = magic
3+
4+
[![Build Status](https://travis-ci.org/Commit451/AdapterLayout.svg?branch=master)](https://travis-ci.org/Commit451/AdapterLayout)
5+
6+
# Gradle Dependency
7+
Easily reference the library in your Android projects using this dependency in your module's `build.gradle` file:
8+
9+
```Gradle
10+
dependencies {
11+
compile 'com.commit451:adapterlayout:1.0.0'
12+
}
13+
```
14+
15+
# Usage
16+
See the sample project for a full sample.
17+
```java
18+
//CheeseAdapter is a RecyclerView adapter
19+
CheeseAdapter cheeseAdapter = new CheeseAdapter();
20+
adapterLinearLayout adapterLinearLayout =
21+
adapterLinearLayout.setAdapter(cheeseAdapter);
22+
```
23+
Later, when you get your data set:
24+
```java
25+
ArrayList<Cheese> cheeses = loadCheeses();
26+
//addAll is a method in our custom RecyclerView.Adapter
27+
cheeseAdapter.addAll(cheeses);
28+
```
29+
At this point, the data will be added to the `LinearLayout` so long as your `RecyclerView.Adapter` works correctly. `onCreateViewHolder` and `onBindViewHolder` will be called as needed.
30+
31+
# But... Why?
32+
This library is useful for displaying data sets that are repeating, but do not need to be recycled as they would be in a `RecyclerView`. This could be the case if you wanted to display a list of items within a `ScrollView`, or wanted to use a custom `ViewGroup` that did not extend `RecyclerView`.
33+
34+
# But Why RecyclerView Adapter?
35+
Most developers should be using `RecyclerView` instead of `ListView` and should be familiar with creating a `RecyclerView.Adapter`. `RecyclerView.Adapter` also enforces the use of `ViewHolder`s which is better for performance. RecyclerView's adapter also allows for better responses to data structure changes via `notifyItemInserted`, `notifyItemRemoved` etc.
36+
37+
# Creating Your Own AdapterLayout
38+
It is simple to create your own `ViewGroup` backed by a `RecyclerView.Adapter`. See `AdapterLinearLayout` and `AdapterLayoutDelegate` for an example of how to create one.
