Issue
I build react native app and I use with scrollView for header with list of text horizontal. The issue is that the height of the scroll view takes half size of the screen. Even after declared it as a style, it still stays as it is.
screen with the scrollView
<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>
)
}
styles
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
As you can see the black size is the scroll View, I want it to be small.
In routes stack into dashboard screen, the style:
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
}
})
Solution
There is an existing limitation with ScrollView
where height
cannot be provided directly.
Wrap the ScrollView
in another View
and give height to that View
.
Like,
render() {
return (
<View style={styles.container}>
<View style={{height: 80}} >
<ScrollView
horizontal
style={{ backgroundColor: 'blue'}}
>
<Text style={{padding: 24}} >title1</Text>
<Text style={{padding: 24}} >title2</Text>
<Text style={{padding: 24}} >title3</Text>
<Text style={{padding: 24}} >title4</Text>
<Text style={{padding: 24}} >title5</Text>
</ScrollView>
</View>
</View>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
paddingTop: Constants.statusBarHeight,
backgroundColor: '#ecf0f1',
},
});

EXTRAS: Unlike height providing width to a ScrollView
will work correctly
