我正在尝试使个人资料图片动起来,但是当我查看它时,它甚至都不会出现。该应用程序不会中断,它只会转到没有图像的页面。我要做的就是创建一个仅用于图片的文件,并将所有代码放在其中,然后将其导出到配置文件页面并在视图中呈现。由于我使用URI链接作为源,因此我确保在const App中而不是在const Styles中对其进行样式设置。有人介意看看并看看可能有什么问题吗?
//HomerProfilePicture.js
import React, { Component } from "react";
import { View, Image, StyleSheet, Animated } from "react-native";
class ImageLoader extends Component {
state = {
opacity: new Animated.Value(0)
};
onLoad = () => {
Animated.timing(this.state.opacity, {
toValue: 1,
duration: 500,
useNativeDriver: true
}).start();
};
render() {
return (
<Animated.Image
onLoad={this.onLoad}
{...this.props}
style={[
{
opacity: this.state.opacity,
transform: [
{
scale: this.state.opacity.interpolate({
inputRange: [0, 1],
outputRange: [0.85, 1]
})
}
]
},
this.props.style
]}
/>
);
}
}
const App = () => (
<View style={styles.container}>
<ImageLoader
style={{
width: "100%",
height: "100%",
marginTop: -250,
alignItems: "center"
}}
resizeMode="cover"
source={{
uri:
"https://assets.fxnetworks.com/cms/prod/shows/the-simpsons/photos/simpsons-sidebar/character-facts/Homer/swsb_character_fact_homer_288x763.png"
}}
/>
</View>
);
const styles = StyleSheet.create({
container: {
flex: 1,
alignItems: "center",
justifyContent: "center"
},
});
export default ImageLoader;
这是我将其导入配置文件的方式:
import ImageLoader from "./HomerProfilePicture";
render() {
return (
<View style={styles.container}>
<ImageLoader />
</View>
);
}
}
