Custom Activity Indicators in React Native: A Step-by-Step Guide

Creating Customized Activity Indicators in React Native

When developing mobile apps, it’s essential to provide users with a seamless experience. One way to achieve this is by using activity indicators to show the app’s progress or loading state. In this article, we’ll explore how to create customized activity indicators in React Native using the inbuilt ActivityIndicator component, community libraries, and the Animated API.

Using the Inbuilt ActivityIndicator Component

The ActivityIndicator component is a built-in React Native component that displays a circular loading indicator. We can customize it by changing its size, color, and animation.

Here’s an example of a basic ActivityIndicator:
“`jsx

import { ActivityIndicator } from ‘react-native’;

const App = () => {
return (

};

const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: ‘center’,
alignItems: ‘center’,
},
});

React Native Loading Spinner Overlay

import { LoadingSpinnerOverlay } from ‘react-native-loading-spinner-overlay’;

const App = () => {
