RecyclerView 可以与CollapsingToolbarLayout一起使用

Item  布局

 <?xml version="1.0" encoding="utf-8"?>
 <LinearLayout
     xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="match_parent"
     android:layout_height="120dp">
     <ImageView
         android:id="@+id/relevantrecommendations_iv"
         android:layout_width="150dp"
         android:layout_height="120dp"
         android:scaleType="center"
         android:src="@drawable/psb"
         />
     <TextView
         android:id="@+id/relevantrecommendations_tv"
         android:layout_width="match_parent"
         android:layout_height="match_parent"
         android:gravity="center_vertical"
         android:text="title"
         android:textSize="20sp"
         />
 </LinearLayout>
