Android Recycler查看项目动态布局

Question

Inside my recycler view item layout I want to add something like horizontal recyclerview layout, because I don't know how many ImageViews I need, that's why I can't create them as a static layout. The number of icons depends on server logic. How can achieve something like the picutre below? Thank you in advance!

Answer 1

You Need Add Horizontal Recyclerview Inside The Main Recyclerview. Your First RecyclerView is Verticle list and inside every index create another RecyclerView It's a Horizontal. so you can display n number of Imageview.

Answer 2

You have to create Recyclerview inside the child layout of your main Recyclerview

Something like

Suppose this is the Main Recyclerview

     <androidx.recyclerview.widget.RecyclerView
                        android:id="@+id/mainRecyclerview"
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"
                        android:orientation="vertical"
                        tools:listitem="@layout/item_demo" />

In your child layout, Let's say item_demo you have to add another Recyclerview for the imageView that you want to show in horizontal

<androidx.recyclerview.widget.RecyclerView
                        android:id="@+id/mainRecyclerview"
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"
                        android:orientation="horizontal"
                        tools:listitem="@layout/item_child" />

item_child layout contains the Imageview that will display horizontally
