react-native - 将视图定位在底部（粘滞页脚），React Native

Question

我有这个组件：

    render() {
    return (
        <ScrollView style={styles.container}>
            <View style={styles.body}>
                <View style={styles.LogoContainer}>
                    <Image resizeMode="contain" style={styles.logo} source={require('../../images/logo.png')}/>
                </View>
                <View style={styles.bottomContainer}>
                    <TextInput selectionColor="white" placeholderTextColor="white" placeholder="Email" style={styles.input} underlineColorAndroid='transparent'/>
                    <TextInput selectionColor="white" placeholderTextColor="white" secureTextEntry={true} placeholder="Password" style={styles.input} underlineColorAndroid='transparent'/>
                    <TouchableOpacity onPress={() => {}} style={styles.btn}>
                        <Text style={styles.btnTxt}>LOG IN</Text>
                    </TouchableOpacity>
                </View>
            </View>
            <View style={styles.footer}>
                <TouchableOpacity onPress={() => {}}>
                    <Text style={[styles.footerTxt, {color: '#fff'}]}>Don’t have an account?</Text>
                </TouchableOpacity>
            </View>
        </ScrollView>
    )
}

我想要的是用style={styles.footer}（粘滞页脚）定位最新视图。我试图设置position: "absolute, bottom:0"，但没有工作。父容器 ( ScrollView) 有height:"100%"和position:"relative"，如果这对 React Native 来说很重要。

我找到了这种方式。首先删除<View style={styles.body}>元素并添加contentContainerStyle到ScrollView这样的：

render() {
return (
        <ScrollView contentContainerStyle={styles.container}>
            <View style={styles.LogoContainer}>
                <Image resizeMode="contain" style={styles.logo} source={require('../../images/logo.png')}/>
            </View>
            <View style={styles.bottomContainer}>
                <TextInput selectionColor="white" placeholderTextColor="white" placeholder="Email" style={styles.input} underlineColorAndroid='transparent'/>
                <TextInput selectionColor="white" placeholderTextColor="white" secureTextEntry={true} placeholder="Password" style={styles.input} underlineColorAndroid='transparent'/>
                <TouchableOpacity onPress={() => {}} style={styles.btn}>
                    <Text style={styles.btnTxt}>LOG IN</Text>
                </TouchableOpacity>
            </View>
            <View style={styles.footer}>
                <TouchableOpacity onPress={() => {}}>
                    <Text style={[styles.footerTxt, {color: '#fff'}]}>Don’t have an account?</Text>
                </TouchableOpacity>
            </View>
        </ScrollView>
      )
}

接下来将这些样式添加到ScrollView：

const styles = StyleSheet.create({
container:{
   flex: 1,
   justifyContent: 'space-between',
}, ....

如果需要，可以添加height到ScrollView > View.
