我将一个Image放置为根节点，以使其成为我的View的背景。但似乎所有其他人的形象都变得无形......
是否可以使用内置组件将图像置于背景之上，而无需任何插件？
在以下代码示例中 landing-background 用作背景，我的 logo 图像可见，但仅在背景被删除时才可见。
Text 在没有任何顾虑的情况下显示在背景之上...
<View style={styles.container}>
<Image source = {require('./img/landing-background.jpg')}
resizeMode = 'cover' style = {styles.backdrop}>
<View style = {styles.overlay}>
<Text style = {styles.headline}>It should appear in front of the Background Image</Text>
<Image style = {styles.logo} source = {require('./img/logo.png')} />
</View>
</Image>
</View>
var styles = StyleSheet.create({
container: {
flex: 1,
alignItems: 'center',
},
overlay: {
opacity: 0.5,
backgroundColor: '#000000'
},
logo: {
backgroundColor: 'rgba(0,0,0,0)',
width: 160,
height: 52
},
backdrop: {
flex:1,
flexDirection: 'column'
},
headline: {
fontSize: 18,
textAlign: 'center',
backgroundColor: 'rgba(0,0,0,0)',
color: 'white'
}
});
而不是将您的内容包装在 <Image>，我认为你最好把它包装成一个 absolute定位元素并具有拉伸以覆盖屏幕。
