RN：左右对齐一行中的项目

Question

这里是 RN (0.59) 组件，使用 sectionList 在一行中显示事件名称。 renderItem 连续呈现 3 个项目，从头像（左图）开始，然后是事件名称，以另一个头像（右图）结束。

render() {
       return (
        <View  style={styles.container}>
          <SectionList
              sections={this.state.activeEvents} 
              renderItem={({item, section}) => {return (
                                                <View style={styles.container}>
                                                  <Image style={styles.image} source={{uri: item.image}}/>
                                                  <TouchableOpacity onPress={() => {this._onPress(item.id)}} >
                                                    <Text style={styles.item} key={item.id}>{item.name}</Text>
                                                  </TouchableOpacity>
                                                  <View style={styles.containerRight}>
                                                    <Image style={styles.image} source={{uri: "https://bootdey.com/img/Content/avatar/avatar1.png"}}/>
                                                  </View>
                                                </View>)}}

              renderSectionHeader={({section}) => <Text style={styles.sectionHeader}>{section.title}</Text>}
              keyExtractor={(item, index) => item + index}
            />
        </View>
      ); 

      }

}

const styles = StyleSheet.create({
    container: {
      flex: 1,
      paddingTop: 22,
      paddingVertical: 12,
      flexDirection: 'row',
      alignItems: 'flex-start',
      flexDirection: 'row',
      alignItems: 'flex-start'
    },
    containerRight: {
      flex: 1,
      paddingTop: 22,
      paddingVertical: 12,
      flexDirection: 'row',
      alignItems: 'flex-end',
      flexDirection: 'row',
      alignItems: 'flex-end' 
    },
    sectionHeader1: {
      paddingTop: 2,
      paddingLeft: 10,
      paddingRight: 10,
      paddingBottom: 2,
      fontSize: 14,
      fontWeight: 'bold',
      backgroundColor: 'rgba(247,247,247,1.0)',
    },
    sectionHeader:{
      backgroundColor : '#64B5F6',
      fontSize : 20,
      padding: 5,
      color: '#fff',
      fontWeight: 'bold'
   },
    item: {
      padding: 10,
      fontSize: 18,
      height: 44,
    },
    image:{
      width:45,
      height:45,
      borderRadius:20,
      marginLeft:20
    },
    imageRight:{
      width:45,
      height:45,
      borderRadius:20,
      marginRight:20
    },
  })

这是上面渲染的输出：

所有行项目（左图、事件名称、右图）都应垂直对齐。左侧图像和事件名称正确对齐到行的左侧，但右侧图像应水平对齐到行的右侧。我怎样才能改变我的 jsx 和样式来实现这个 UI?

我想你会喜欢这样的东西：

您可以通过为该行添加一个大容器并添加：

来完成此操作

justifyContent: 'space-between'

It looks close. But I was not able to do any test since my post because of an error related to AndroidX. Can you move the event.name to the left right after the left image? For the icon on the right, it may be changed to a hamburger menu

只要把左边的图标换成

就很简单了

<View>
  <Image/>
  <Text>Some Text</Text>
</View>

那么它看起来像这样：

查看更新的点心：snack.expo.io/@abranhe/Whosebug-56638124-updated

<View style={styles.leftIcon}>
  <Image style={styles.image} source={event.imageLeft} />
  <TouchableOpacity onPress={() => this.onPressEvent(event.name)}>
    <Text>{event.name}</Text>
  </TouchableOpacity>
</View>

然后添加如下样式：

leftIcon: {
  flexDirection: 'row',
  justifyContent: 'center',
  alignItems: 'center',
}
