Using Recycler View

First add 

implementation 'com.android.support:recyclerview-v7:27.1.1'

to build.gradle

activity_main.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    xmlns:tools="http://schemas.android.com/tools"    tools:context=".MainActivity"    xmlns:android="http://schemas.android.com/apk/res/android">

    <android.support.v7.widget.RecyclerView        android:id="@+id/recyclerView"        android:layout_width="match_parent"        android:layout_height="match_parent"        android:scrollbars="vertical"/> 
</LinearLayout>

contact.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout    android:orientation="vertical"    xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent"    android:layout_height="wrap_content">
