#### 引包
~~~
compile 'com.jcodecraeer:xrecyclerview:1.5.9'
~~~
#### 说明
本篇使用一个例子说明XRecyclerView的使用。在使用过程中，模拟10条数据一页，然后加载更多，如果十条数据没有占满整个屏幕，那么加载更多功能也就失效了，也许这是个bug，但在正式开发中几乎不会有影响（很少出现一页数据还占不满屏幕的情况）
#### 列表布局
~~~
<com.jcodecraeer.xrecyclerview.XRecyclerView
android:id="@+id/recyclerview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="20dp"
android:background="#ffffff"/>
~~~
#### 子列表项布局
~~~
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="100dp">
<TextView
android:id="@+id/tv"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="test"
android:gravity="center"/>
</LinearLayout>
~~~
