Android supports adding custom components in its pre-built widgets such as TextView, ListView, Button, RadioButton, ToggleButton, CheckBox, Gallery etc. This is because sometimes you may feel unsatisfied with the default widgets and you may want to customize them. So, you can do that by making small adjustments to an existing widget or layout. You need to create a subclass of that widget or layout that will give you control over the Class or the widget.
To create a custom component, you need to follow the steps described below:
- The first step is to create an Android application with the help of Android Studio IDE. The application will be created under a package com.example.greatlearning.firstapp
- In the next step, you need to create an XML that you can use to define new attributes with their data types.
- Now, you will need to create a Java file that contains a custom component.
- Next, you have to modify the XML file that contains the main activity and you need to add the code to create a Color compound view with some new attributes.
- At last, you have to run the application and verify the outcome of the application.
