【问题描述】:
我已经阅读了几个 flexbox 教程,但我仍然无法完成这个简单的任务。
如何将红色框设为 100% 宽度?
代码:
<View style={styles.container}>
<Text style={styles.welcome}>
Welcome to React Natives
</Text>
<Text style={styles.line1}>
line1
</Text>
<Text style={styles.instructions}>
Press Cmd+R to reload,{'\n'}
Cmd+D or shake for dev menu
</Text>
</View>
风格:
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#F5FCFF',
borderWidth: 1,
flexDirection: 'column',
},
welcome: {
fontSize: 20,
textAlign: 'center',
margin: 10,
borderWidth: 1,
},
line1: {
backgroundColor: '#FDD7E4',
},
instructions: {
textAlign: 'center',
color: '#333333',
marginBottom: 5,
borderWidth: 1,
},
谢谢!

Nishanth Shankar 的建议,添加
flex:1 用于包装器,
flexDirection: 'row'
输出:
代码:
<View style={styles.container}>
<View style={{flex:1}}>
<Text style={styles.welcome}>
Welcome to React Natives

<View style={{flex:1}}>
<Text style={styles.line1}>

</Text>

<View style={{flex:1}}>
<Text style={styles.instructions}>
