问题描述

我已经阅读了几个flexbox教程,但是我仍然无法完成这个简单的任务。



我怎样才能让红框达到100%的宽度? / p>



代码:

 < View style = {styles.container}> 
< Text style = {styles.welcome}>
欢迎使用React Natives
< / Text>
< Text style = {styles.line1}>
line1
< / Text>
< Text style = {styles.instructions}>
按Cmd + R重新加载,{'\ n'}
Cmd + D或摇动开发菜单
< / Text>
< / View>

style:

  container:{
flex:1,
justifyContent:'center',
alignItems:'center',
backgroundColor:'#F5FCFF',
borderWidth:1,
flexDirection:'column',
},
welcome:{
fontSize:20,
textAlign:'center',
边距:10,
borderWidth:1,
},
line1:{
backgroundColor:'#FDD7E4',
},
指令:{
textAlign:'center',
color:'#333333',
marginBottom:5,
borderWidth:1,
},

$ p
$ p
$ b

更新1:
Nishanth Shankar的建议,增加
flex:1为包装,
flexDirection:'row'



输出:

$ b $ div

解决方案

只要添加 alignSelf:stretch到项目的样式表。

  line1:{
backgroundColor:'#FDD7E4',
alignSelf:'stretch',
textAlign:'center',
},


I have already read several flexbox tutorial, but I still cannot make this simple task to work.

How can I make the red box to 100% width?

Code:

  <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>

style:

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,
},

Thank you!

Update 1: Suggestion by Nishanth Shankar, adding flex:1 for the wrapper, flexDirection: 'row'

Output:

Code:

  <View style={styles.container}>
    <View style={{flex:1}}>
      <Text style={styles.welcome}>
        Welcome to React Natives
      </Text>
    </View>
    <View style={{flex:1}}>
      <Text style={styles.line1}>
        line1
      </Text>
    </View>
    <View style={{flex:1}}>
      <Text style={styles.instructions}>
        Press Cmd+R to reload,{'\n'}
        Cmd+D or shake for dev menu
      </Text>
    </View>
  </View>

  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#F5FCFF',
    borderWidth: 1,
    flexDirection: 'row',
    flexWrap: 'wrap',
  },
  welcome: {
    fontSize: 20,
    textAlign: 'center',
    margin: 10,
    borderWidth: 1,
  },
  line1: {
      backgroundColor: '#FDD7E4',
  },
  instructions: {
    textAlign: 'center',
    color: '#333333',
    marginBottom: 5,
    borderWidth: 1,
  },

解决方案

Simply add alignSelf: "stretch" to your item's stylesheet.

line1: {
    backgroundColor: '#FDD7E4',
    alignSelf: 'stretch',
    textAlign: 'center',
},
