I have three TouchableHighlight elements wrapping three views (aligned next to each other). Onpress I would like to change the style (backgroundColor) and image of the view (the pressed view would become active).
<View style={styles.circle}>
should become 'red' and image source should be 'arrow-win-active.png' <Image source={require('../images/arrow-win.png')} style={styles.arrowWin}></Image>
What would be the best way to do it?
Here is a screenshot:
Here is my code so far:
import React from 'react'
import {
View,
ListView,
ScrollView,
StyleSheet,
Image,
TouchableHighlight,
} from 'react-native'
const changeStyle = () => {
console.log('change style')
}
const appView = (game, date) =>
<ScrollView style={styles.container}>
<View style={styles.step}>
<View style={{flex:1}}>
<View style={styles.pickContainer}>
<TouchableHighlight onPress={() => changeStyle()} style={{flex:1}}>
<View style={styles.pickWrapper}>
<View style={styles.circle}>
<Image source={require('../images/arrow-win.png')} style={styles.arrowWin}></Image>
</View>
</View>
</TouchableHighlight>
<TouchableHighlight style={{flex:1}}>
<View style={styles.pickWrapper}>
<View style={styles.circle}>
<Image source={require('../images/arrow-draw.png')} style={styles.arrowDraw}></Image>
</View>
</View>
</TouchableHighlight>
<TouchableHighlight style={{flex:1}}>
<View style={styles.pickWrapper}>
<View style={styles.circle}>
<Image source={require('../images/arrow-win.png')} style={styles.arrowWin}></Image>
</View>
</View>
</TouchableHighlight>
</View>
</View>
</View>
</ScrollView>
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: '#e1e1e1'
},
step: {
backgroundColor: '#ffffff',
borderRadius: 4,
borderLeftWidth: 5,
flex: 1,
marginLeft: 10,
marginRight: 10,
marginBottom: 10,

shadowColor: 'black',
textAlign: 'center',
},
heading: {
textAlign: 'center',

fontSize: 15,

},
pickContainer: {

flexDirection: 'row',

},
pickWrapper: {
flex: 1,
flexDirection: 'row',

export default appView
You have to change AppView
to class based component because you have to access state
.
import React. {Component} from 'react'
import {
View,
ListView,
ScrollView,
StyleSheet,
Image,
TouchableHighlight,
} from 'react-native'
class AppView extends Component {
state = {
isPlayer1ButtonActive: false,
isDrawButtonActive: false,
isPlayer2ButtonActive: false,
}
activateButton = buttonToActivate => {
const newState = Object.assign(
{},
{
isPlayer1ButtonActive: false,
isDrawButtonActive: false,
isPlayer2ButtonActive: false,
},
{[buttonToActivate]: true},
)
this.setState(newState);
}
render() {
const {isPlayer1ButtonActive, isDrawButtonActive, isPlayer2ButtonActive} = this.state
return (
<ScrollView style={styles.container}>
<View style={styles.step}>
<View style={{flex:1}}>
<View style={styles.pickContainer}>
<TouchableHighlight onPress={() => activateButton('isPlayer1ButtonActive')} style={{flex:1}}>
<View style={styles.pickWrapper}>
<View style={[styles.circle, isPlayer1ButtonActive && styles.circleActive]}>
<Image
source={isPlayer1ButtonActive ? require('../images/arrow-win-active.png') : require('../images/arrow-win.png')}
style={styles.arrowWin}
/>
</View>
</View>
</TouchableHighlight>
<TouchableHighlight onPress={() => activateButton('isDrawButtonActive')} style={{flex:1}}>
<View style={styles.pickWrapper}>
<View style={[styles.circle, isDrawButtonActive && styles.circleActive]}>
<Image
source={isDrawButtonActive ? require('../images/arrow-draw-active.png') : require('../images/arrow-draw.png')}
style={styles.arrowDraw}
/>
</View>
</View>
</TouchableHighlight>
<TouchableHighlight onPress={() => activateButton('isPlayer2ButtonActive')} style={{flex:1}}>
