Reactnative react native scrollView 高度始终保持静态不变

我构建了react-native 应用程序，并与scrollView一起使用标题和水平文本列表.

带有滚动视图的屏幕

            <View style={Style.container} >
                {this.props.ExtendedNavigationStore.HeaderTitle ? <BackHeader header={this.props.ExtendedNavigationStore.HeaderTitle} onPressBack={this.goBack} /> : <Header openDrawer={this.openDrawer} />}
                <ScrollView  contentContainerStyle={{flexGrow:1}} style={Style.scrollableView} horizontal showsHorizontalScrollIndicator={false}>
                    {this.renderScrollableHeader()}
                </ScrollView>
                <Routes /> /* stack with dashboard screen */
            </View>
        </Drawer>

    )
}

风格

import {StyleSheet} from 'react-native'
import {calcSize} from '../../utils'


const Styles = StyleSheet.create({
    container : {
        flex:1,  
        backgroundColor:"#e9e7e8"      
    },
    scrollableView:{
        height: calcSize(40),
        backgroundColor: '#000',

    },
    textCategory:{
        fontSize: calcSize(25),
        color:'#fff'
    },
    scrollableButton:{
        flex:1,
        margin:calcSize(30)
    }
})

export default Styles

正如你所看到的，黑色大小是滚动视图，

在"路由堆叠到仪表板"屏幕中，样式:

const Style = StyleSheet.create({
    container: {
        backgroundColor: '#9BC53D',
        flex: 1,
        justifyContent: 'space-around',
        alignItems: 'center'
    },
    text: {
        fontSize: 35,
        color: 'white',
        margin: 10,
        backgroundColor: 'transparent'
    },
    button: {
        width: 100,
        height: 75,
        margin: 20,
        borderWidth: 2,
        borderColor: "#ecebeb",
        justifyContent: "center",
        alignItems: "center",
        borderRadius: 40
    }
})
