In Android Studio, there are different types of views to design our android applications. Views such as ImageView, TextView, ListView, etc. These types of views help you to make the user interface friendly. You can drag or drop the view in the XML design section or you can simply write the code in the XML code section.
ListView is one of the views from the view group which shows the data in a vertical scrollable format. It enhances the user experience as it makes the list easily understandable for users.
In this article, we are going to create a simple list using an array adapter.
We will store string data in an array and display the respective data in a list format.
Before that, we need to understand a few concepts used for creating a list such as adapters.
The adapter is present between the view and data. It helps to display data in views. All the data items are loaded in the adapter and with the help of view/UI, the data items are displayed.
There are different types of adapters that are used as per their requirements.
In this article, we will focus on ArrayAdapter only.
In the below example, we have used ArrayAdapter to display our list items into our list.
In MainActivity.java, you can see I have created an array list called as listTopics in which all the list items are present in it.
Now, the same array list will be used in our ArrayAdapter to display the data using our list. Firstly, we will create an ArrayAdapter then we will set the adapter and it will be ready to show our listTopics in our list.
Step 1: Create New Project in Android Studio.
Choose Empty Activity and then type the Application Name as “ListView Demo”.
Step 2: Write the below code in activity_main.xml – LinearLayout and List
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" tools:context=".MainActivity"> <ListView android:id="@+id/listView" android:layout_width="match_parent" android:layout_height="match_parent" /> </LinearLayout>
Step 3: Write the below code in MainActivity.java.
