In this chapter we will show you how to use the activityindicator in React Native.
Step 1: App
App component will be used to import and show our ActivityIndicator.
App.js
import React from 'react'
import ActivityIndicatorExample from './activity_indicator_example.js'
const Home = () => {
return (
<ActivityIndicatorExample />
)
}
export default Home
Step 2: ActivityIndicatorExample
Animating property is a Boolean which is used for showing the activity indicator. The latter closes six seconds after the component is mounted. This is done using the closeActivityIndicator() function.
activity_indicator_example.js
import React, { Component } from 'react';
import { ActivityIndicator, View, Text, TouchableOpacity, StyleSheet } from 'react-native';
class ActivityIndicatorExample extends Component {
state = { animating: true }
closeActivityIndicator = () => setTimeout(() => this.setState({
animating: false }), 60000)
componentDidMount = () => this.closeActivityIndicator()
render() {
const animating = this.state.animating
return (
<View style = {styles.container}>
<ActivityIndicator
animating = {animating}
color = '#bc2b78'
size = "large"
style = {styles.activityIndicator}/>
</View>
)
}
}
export default ActivityIndicatorExample
const styles = StyleSheet.create ({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
marginTop: 70
},
activityIndicator: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
height: 80
}
})
When we run the app, we will see the loader on screen. It will disappear after six seconds.
