How to create Array List in Kotlin Android ?

When I was learning to create array list wasn’t understood how important array is but I have understood importance of array when I worked at one or two applications. we use array for spinner, storing data in a array etc.

Array is a collection of similar data type. it’s mean in a array we can keep similar type of data. we can add data and delete data in a array .

For creating an array list we need a List View , a xml file and a class file

Let’s write codes,

In activity_main.xml

<ListView
    android:background="#294CC4"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/array_list_view"/>

create an .xml file for list item

In .xml file (array_list_item.xml )

<?xml version="1.0" encoding="utf-8"?>
<TextView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="15dp"
    android:id="@+id/label">

</TextView>

In a Class File ( MainActivity.kt or other Class file )

val arrayList  =  arrayOf("sudish","akash","rahul","viksh","arman","ansar","ajay",
  "pradhum","nehal","ravi","aditya","rohit","binay","sanjit","sanjay","akash","rahul","viksh","arman","ansar","ajay",
    "pradhum","nehal","ravi","aditya","rohit","binay","sanjit","sanjay")
val listView=findViewById(R.id.array_list_view) as ListView

val adapter=ArrayAdapter(this,R.layout.array_list_item ,arrayList)
listView.adapter=adapter

That’s all for this story you can try it. it is working proper ✔✔ , Thank you 👍👍👍
