ScrollView with position absolute is not scrolling in android [react native]

I want to make dropdown view using scrollview in react native, but scrollview is not scrolling in android while its position is absolute, in IOS it is scrolling like a charm.

This is my code

   <View style={{ flexDirection: 'row', zIndex: 1 }}>
        <TouchableOpacity
            style={styles.contryCode}
            onPress={()=>setVisible(prev=>!prev)}
        >
            <Text style={styles.selectedCode}>{code}</Text>
            <Icon name={visible ? 'up' : 'down'} size={15} color='#000' />
        </TouchableOpacity>
        {visible ? <CodeList /> : null}
    </View>

const CodeList = () => {
    return (
        <ScrollView
            style={styles.codeList}
            showsVerticalScrollIndicator={false}
        >
            {codes.map((item: any, index: number) => {
                return (
                    <TouchableOpacity key={index} onPress={() =>     handleSelectCountry(item?.phonecode)}>
                        <Text style={styles.codeText}>{item.phonecode}</Text>
                    </TouchableOpacity>
                );
            })}
        </ScrollView>
    )
 }

I also tried wrapping Scrollview with posotion:'relative' in a View with position:'absolute', but it did not worked.
