试图更改我的传送带元素上按钮的图像时,当我单击其中任何一个时,它(下面的代码)会更改所有图像。我只想改变目前的旋转木马的形象。有任何想法吗?由于React Native onPress活动状态在Carousel上更改图像源
class CarouselImages extends React.Component {
constructor(props) {
super(props);
this.state = {
myImagesArray: [
{
key: 1,
title: 'Category'
},
{
key: 2,
title: 'Category'
},
{
key: 3,
title: 'Category'
}
],
icon_active: false,
}
activateCarouselButton = a => {
const newState = Object.assign(
{},
{
icon_active: false,
},
{ [a]: true },
)
this.setState(newState);
}
}
render =() => {
const { icon_active } = this.state;
var myCarousel = this.state.myImagesArray.map(function (index) {
return (
<View key={index}>
<TouchableHighlight onPress={() => activateCarouselButton('icon_active')} >
<Image
source={icon_active ? require('../Image/[email protected]') : require('../Image/[email protected]')} />
</TouchableHighlight>
</View>
);
});
return (
<View>
<Carousel
style={{ backgroundColor: '#fff' }}>
{myCarousel}
</Carousel>
</View>
)
}
}
