Android Horizontal and Vertical RecyclerView Example

Declare Android RecyclerView in your main layout file

<?xml version="1.0" encoding="utf-8"?> <LinearLayout     android:orientation="vertical"     xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:tools="http://schemas.android.com/tools"     android:layout_width="match_parent"     android:layout_height="match_parent"     tools:context=".MainActivity">     <android.support.v7.widget.RecyclerView         android:id="@+id/vertical_recycler_view"         android:background="#fff"         android:layout_weight="1"         android:layout_width="match_parent"         android:layout_height="0dp"/>     <View         android:background="#787878"         android:layout_width="match_parent"         android:layout_height="3dp"/>     <android.support.v7.widget.RecyclerView         android:id="@+id/horizontal_recycler_view"         android:background="#fff"         android:layout_width="match_parent"         android:layout_height="70dp"/> </LinearLayout>

Horizontal RecyclerView’s single item View.

<?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="match_parent">           <TextView         android:textColor="#787878"         android:textSize="18sp"         android:padding="16dp"         android:id="@+id/txtView"         android:layout_width="wrap_content"         android:layout_height="wrap_content" /> </LinearLayout>

Vertical RecyclerView’s single item View.

<?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="match_parent">     <TextView         android:textColor="#787878"         android:textSize="18sp"         android:padding="16dp"         android:id="@+id/txtView"         android:layout_width="wrap_content"         android:layout_height="wrap_content" /> </LinearLayout>
