react native android scroll view not working

Question

I have a react native component like:

import React, { Component } from 'react';
import { StyleSheet, Text, View, ScrollView } from 'react-native';

import Level from './Level';

class LevelList extends Component {
    render() {

        return (
            <ScrollView style={styles.scrollView} >
                <View style={styles.levelList}>
                    <Level />
                    <Level />
                    <Level />
                    <Level />
                    <Level />
                    <Level />
                </View>
            </ScrollView>
        )
    }
}

var styles = StyleSheet.create({
    scrollView: {
    backgroundColor: '#fff',
    flex: 1,
    },
    levelList: {
        marginTop: 50,
        flexDirection:'column',
        alignItems: 'center',
    },

})

export default LevelList;

Here <Level> is simply a component that holds a text.

I have <LevelList> in my container like:

class LevelListView extends Component {
    render() {
        return (
            <View style={{flex: 1}}>
                <Header />
                <LevelList />
            </View>
        )
    }
}

export default LevelListView

Here I get a scrollbar in the side of my list but it does not get scrolled. What am I missing here ?

I am running the app in emulator:

Update:

import React, { Component } from 'react';

import { StyleSheet, Text, View } from 'react-native';

class Header extends Component {
    render() {
        return (
            <View style={styles.toolbar}>
                <Text style={styles.toolbarBack}>Back</Text>
                <Text style={styles.toolbarTitle}>Levels</Text>
            </View>
        )
    }
}

var styles = StyleSheet.create({
    toolbar:{
        backgroundColor:'#00bcd4',
        paddingTop:10,
        paddingBottom:10,
        flexDirection:'row'
    },
    toolbarTitle:{
        color:'#fff',
        textAlign:'center',
        fontSize:20,
        fontWeight:'bold',
        marginRight: 30,
        flex:1
    },
    toolbarBack: {
        color: '#fff',
        fontSize: 14,
        fontWeight: 'bold',
        marginTop: 4,
        marginLeft: 10,
    }
})

export default Header;

Answer 1

I had the same problem and tried everything on the internet like flex:1 solutions... But the problem is, Android is not letting you use nested scroll with scrollview. I just put:

nestedScrollEnabled={true} 

Command to my scrollview object and it worked like a charm.

I had the similar problem but I resolved it by doing this:

<ScrollView style={{ 

    height:Dimensions.get('screen').height

    }}>
       ///
    </ScrollView>
