问题描述

似乎我在创建显示时遇到问题:内联样式与flexbox等效。到目前为止,我已经实现了以下(其中红色和蓝色线由边界函数管理,以帮助造型):





使用此代码:

  var React = require ('react-native'); 
var {
View,
ScrollView,
Image,
StyleSheet,
Text,
TouchableHighlight,
} = React;

//附加库
var Parse = require('parse / react-native'); //解析数据存储
Icon = require('react-native-vector-icons / Ionicons'); // vector icons

// dimensions
var Dimensions = require('Dimensions');
var window = Dimensions.get('window');

//动态变量组件
var ImageButton = require('../ common / imageButton');
// var KeywordBox = require('./ onboarding / keyword-box');

module.exports = React.createClass({
render:function(){
return(
< View style = {[styles.container]}> ;
< Image
style = {styles.bg}
source = {require('./ img / login_bg1_3x.png')}>
< View style = {[styles.header,this.border('red')]}>
< View style = {[styles.headerWrapper]}>
< Image
resizeMode = { 'contain'}
style = {[styles.onboardMsg]}
source = {require('./ img / onboard_msg.png')}>
< / Image>
< / View>
< / View>
< View style = {[styles.footer,this.border('blue')]}>
&
horizo​​ntal = {false}
style = {styles.footerWrapperNC}
contentContainerStyle = {[styles.footerWrapper]}>
{this.renderKeywordBoxes()}
< / ScrollView>
< / View>
< / Image>
< / View>
);
},
renderKeywordBoxes:function(){
//在keyword.js中呈现关键字数组
//并将它们映射到自定义组件关键字框中以在入职时显示
// component
var关键字= ['LGBQT','#BlackLivesMatter','艺术','嘻哈','历史',
'政治','喜剧','时尚','创业','技术','商业',
'国际','健康','趋势','音乐','运动','entertianment'

return关键字.map(function(keyword,i){
return< TouchableHighlight
style = {styles.keywordBox}
key = {i}
underlayColor = {'rgb(176,224,230,0.6)'}>
< Text style = {styles.keywordText}> {keyword}< / Text>
< / TouchableHighlight>
});
},
//帮助布局flexbox itmes的函数
//使用颜色参数来构造边框,这是一个额外的
//风格,因为我们不想弄乱我们真正的造型
border:function(color){
return {
borderColor:color,
borderWidth:4,
}
},
});

styles = StyleSheet.create({
header:{
flex:2,
},
headerWrapper:{
flex:1 ,
flexDirection:'column',
alignItems:'center',
justifyContent:'space-around',
marginTop:window.height / 35,
} ,
onboardMsg:{
width:(window.width / 1.3),
height:(452/1287)*((window.width / 1.3)),
}
footer:{
flex:7,
marginTop:window.height / 35,
},
// scrollview的容器样式包装
footerWrapper: {
flexWrap:'wrap',
alignItems:'flex-start',
},
// scrollview的非容器样式封装器
footerWrapperNC:{
flexDirection:'row',

},
container:{
flex:1,
alignItems:'center',
justifyContent: 'center',
},
bg:{
flex:1,
width:window.width,
height:window.height,
} ,
actionButtonIcon:{
fontSize:20,
height:22,
color:'white',
},
keywordText:{
fontFamily:'Bebas Neue',
fontSize:18,
padding:6,
fontWeight:'bold',
color:'white',
letterSpacing: 1.5,
textAlign:'center'
},
keywordBox:{
backgroundColor:'transparent',
margin:3,
borderColor:'rgb (176,224,230,0.6)',
borderWidth:1,
},
});

但我想实现:





任何想法?



解答:



需要将样式更改为以下内容:

  // scrollview的容器样式封装器
footerWrapper:{
flexWrap:'wrap',
alignItems:'flex-start',
flexDirection:'row',
},
// scrollview的非容器样式封装器
footerWrapperNC:{
flexDirection:'column',
},
/ pre>

因此,在scrollView中使用flexDirection在column和row中可以让孩子留在内部

解决方案

需要将样式更改为以下样式:

  // scrollview的容器样式包装
footerWrapper:{
flexWrap:'wrap',
alignItems:'flex-start',
flexDirection:'row',
},
//非容器scrollview的样式封装器
footerWrapperNC:{
flexDirection:'column',
},


It seems as though I am having problems with creating a display: inline styling equivalent with flexbox. So far I have achieved the following (where the red and blue lines are governed by the border function to help with styling):

With this code:

var React = require('react-native');
var {
    View, 
    ScrollView, 
    Image,
    StyleSheet,
    Text, 
    TouchableHighlight,
} = React;

//additional libraries
var Parse = require('parse/react-native'); //parse for data storage
Icon = require('react-native-vector-icons/Ionicons'); //vector icons

//dimensions
var Dimensions = require('Dimensions');
var window = Dimensions.get('window');

//dynamic variable components
var ImageButton = require('../common/imageButton');
//var KeywordBox = require('./onboarding/keyword-box');

module.exports = React.createClass({
    render: function() {
        return (
            <View style={[styles.container]}>
                <Image 
                    style={styles.bg} 
                    source={require('./img/login_bg1_3x.png')}>
                    <View style={[styles.header, this.border('red')]}>
                        <View style={[styles.headerWrapper]} >
                            <Image 
                                resizeMode={'contain'}
                                style={[styles.onboardMsg]}
                                source={require('./img/onboard_msg.png')} >
                            </Image>
                        </View>
                    </View>
                    <View style={[styles.footer, this.border('blue')]}>
                        <ScrollView 
                            horizontal={false}
                            style={styles.footerWrapperNC}
                            contentContainerStyle={[styles.footerWrapper]}>
                            {this.renderKeywordBoxes()}
                        </ScrollView>
                    </View>
                </Image>
            </View>
        );
    }, 
    renderKeywordBoxes: function() {
        //renders array of keywords in keyword.js
        //and maps them onto custom component keywordbox to show in the onboarding
        //component
        var Keywords = ['LGBQT', '#BlackLivesMatter', 'Arts', 'Hip-Hop', 'History', 
        'Politics', 'Comedy', 'Fashion', 'Entrepreneurship', 'Technology', 'Business', 
        'International', 'Health', 'Trending', 'Music', 'Sports', 'Entertianment'];

        return Keywords.map(function(keyword, i) {
            return <TouchableHighlight 
                style={styles.keywordBox} 
                key={i}
                underlayColor={'rgb(176,224,230, 0.6)'} >
                <Text style={styles.keywordText} >{keyword}</Text>
            </TouchableHighlight>
        });
    }, 
    //function that helps with laying out flexbox itmes 
    //takes a color argument to construct border, this is an additional 
    //style because we dont want to mess up our real styling 
     border: function(color) {
        return {
          borderColor: color, 
          borderWidth: 4,
        } 
     },
});

styles = StyleSheet.create({
    header: {
        flex: 2,
    }, 
    headerWrapper: {
        flex: 1, 
        flexDirection: 'column', 
        alignItems: 'center',
        justifyContent:'space-around',
        marginTop: window.height/35,
    },
    onboardMsg: {
        width: (window.width/1.3), 
        height: (452/1287)*((window.width/1.3)),
    },
    footer: {
        flex: 7, 
        marginTop: window.height/35,
    }, 
    //container style wrapper for scrollview
    footerWrapper: {
        flexWrap: 'wrap', 
        alignItems: 'flex-start',
    },
    //non-container style wrapper for scrollview
    footerWrapperNC: {
        flexDirection:'row',

    },
    container: {
        flex: 1, 
        alignItems: 'center', 
        justifyContent: 'center',
    }, 
    bg: {
        flex: 1,
        width: window.width, 
        height: window.height, 
    },
    actionButtonIcon: {
        fontSize: 20,
        height: 22,
        color: 'white',
    },
    keywordText: {
        fontFamily: 'Bebas Neue', 
        fontSize: 18, 
        padding: 6, 
        fontWeight: 'bold',
        color: 'white', 
        letterSpacing: 1.5,
        textAlign: 'center'
    }, 
    keywordBox: {
        backgroundColor: 'transparent',
        margin: 3, 
        borderColor: 'rgb(176,224,230, 0.6)', 
        borderWidth: 1,
    },
});

But I would like to achieve this:

any ideas?

EDIT** ANSWER:

Needed to change the styling to the following:

//container style wrapper for scrollview
    footerWrapper: {
        flexWrap: 'wrap', 
        alignItems: 'flex-start',
        flexDirection:'row',
    },
    //non-container style wrapper for scrollview
    footerWrapperNC: {
        flexDirection:'column',
    },

So use of flexDirection in column and row for scrollView works children stay inline

解决方案

//container style wrapper for scrollview
    footerWrapper: {
        flexWrap: 'wrap', 
        alignItems: 'flex-start',
        flexDirection:'row',
    },
    //non-container style wrapper for scrollview
    footerWrapperNC: {
        flexDirection:'column',
    },
