In this example, the animating property set the activity indicator to true, and it is visible on the screen. When the component mounts, the animated activity indicator will be closed after six seconds using the closeActivityIndicator() method.
import React,{Component} from 'react';
import { Picker, View, StyleSheet, ActivityIndicator } from 'react-native';
export default class ActivityIndicatorDemo extends Component {
state = { animating: true }
closeActivityIndicator = () => setTimeout(() => this.setState({
animating: false
}), 6000)
componentDidMount = () => this.closeActivityIndicator()
render() {
const animating = this.state.animating
return (
<View style={[styles.container, styles.horizontal]} >
<ActivityIndicator animating={animating} size="large" color="#ff0000" />
<ActivityIndicator size="small" color="#44ff00" />
<ActivityIndicator size="large" color="#rtwrw" />
</View>
)
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center'
},
horizontal: {
flexDirection: 'row',
justifyContent: 'space-around',
padding: 10
}
});
