Android中RecyclerView上拉下拉,分割线，多条目的实例代码

//activity的xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:tools="http://schemas.android.com/tools"
 android:id="@+id/activity_main"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 tools:context="baway.com.cj.myrecyclerview2.MainActivity">
 <android.support.v4.widget.SwipeRefreshLayout
   android:id="@+id/swipeRefreshLayout"
   android:layout_width="match_parent"
   android:layout_above="@+id/progress"
   android:layout_height="match_parent">
   <android.support.v7.widget.RecyclerView
     android:id="@+id/recyclerView"
     android:layout_width="match_parent"
     android:layout_height="match_parent">
   </android.support.v7.widget.RecyclerView>
 </android.support.v4.widget.SwipeRefreshLayout>
 <ProgressBar
   android:id="@+id/progress"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:layout_centerHorizontal="true"
   android:visibility="gone"
   android:layout_alignParentBottom="true"/>
</RelativeLayout>
item1的xml和item2的xml就一个背景颜色不同
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:tools="http://schemas.android.com/tools"
 android:id="@+id/activity_main"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:background="#f00000"
 tools:context="baway.com.cj.myrecyclerview2.MainActivity">
 <TextView
   android:id="@+id/name"
   android:layout_width="match_parent"
   android:layout_height="50dp"
   android:textSize="20sp"
   android:gravity="center"
   android:textColor="#00ff00"/>
</RelativeLayout>
item2
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
