如何在本机中使用滚动视图

Question

我正在尝试为客户创建购物应用，并且我想将滚动属性添加到应用的购物车页面，因此我使用了

`scrollview`

属性，我立即添加了scrollview并重新加载了所有分散的应用程序。

这里是没有scrollveiw的原始页面

这是带有scrollview的页面

我经过研究后通过将contentContainerStyle={{flex:1}}添加到scrollview来解决此问题，此后我在页面上添加了更多内容，但没有滚动，我不知道为什么，也许我可能正在做某事错误的是此页的代码

 <ScrollView contentContainerStyle={{flex:1}}>
    <View style={styles.page}>
       <Cartheader gotocart={gotocart} gotohome={gotohome} />
       <View style={{justifyContent:'space-between', alignItems:'center'}}>
       <View style = {styles.up}>

        <TouchableOpacity style={styles.back} onPress={gtoback}>
            <Image style={styles.arrowb} source={require('../resources/arrowback.png')} />
        </TouchableOpacity>

        <View style={styles.overall}>
            <View style = {styles.title}><Text style={{fontSize:RFPercentage(5),fontWeight:'bold',marginLeft: '4%',}}>Cart</Text></View>
