When I scroll vertically up and down, animation starts lagging in the first two components (CompetitionsList, CampList) after the slider (BannerSwiper). I couldn’t fix it. I tried using Animation.ScrollView with "UseNativeDriver: true", but it didn’t help. Something might be wrong with css.
Here is a gif of screen:

This is my code:
export default class HomeComponent extends React.Component {
render() {
return (
<View style={styles.container}>

<CompetitionsList home={true} {...this.props}/>
<CustomDivider/>
<CampList home={true} {...this.props}/>
<CustomDivider/>
<NewsComponent home={true} {...this.props}/>
<CustomDivider/>
<AthletesBirthdayList {...this.props}/>
<CustomDivider/>
<RatingsBlock/>
<CustomDivider/>
<SocialBlock/>
</ScrollView>
</View>
);
}
}
const styles = StyleSheet.create({

Remove the marginRight from SubmitButtonStyle and the marginLeft from SubmitButtonStyle2 and you should be fine.
I´m trying without success to use the ScrollView component in React Native, below the code:
const width_proportion = '97%';
const height_proportion = '75%';
const styles = StyleSheet.create({
container: {
height: '100%'
},
image: {
flex: 1,
resizeMode: "cover",
justifyContent: "center"
},
text: {
color: "grey",
fontSize: 30,
fontWeight: "bold"
},
popup: {
color: '#CA0',
},
box: {
width: width_proportion,
height: height_proportion,
alignItems: 'center',
justifyContent: 'center',
backgroundColor: 'steelblue',
// position: "absolute",
marginTop: '5%',
marginBottom: '3%',
marginLeft: '2%'
},
bottomBox: {
width: '97%',
height: 125,
backgroundColor: 'steelblue',
marginLeft: '2%',
marginBottom: 10,
marginTop: 5,
padding: 5
}
});
const MyTheme = {
colors: {
...DefaultTheme.colors,
background: '#EFA',
primary: '#000',
text: '#000',
},
};
function HomeScreen({ navigation }) {
return (
<View style={styles.container}>
<View style={{ width: '100%', height: 50, backgroundColor: 'steelblue' }}>
<TouchableOpacity onPress={() => navigation.toggleDrawer()}>
<Image source={hamburgerMenu} style={{ height: 45, width: 45, alignItems: 'center' }}>
</Image>
</TouchableOpacity>
</View>
<ImageBackground source={imgBackground} style={styles.image}>
<View style={styles.box}>
</View>
<ScrollView horizontal={true} >
<View style={styles.bottomBox}>
</View>
<View style={styles.bottomBox}>
</View>
<View style={styles.bottomBox}>
</View>
</ScrollView>
</ImageBackground>
</View >
);
}
When I set the horizontal property to "true" from ScrollView, the component disappears. Only I set horizontal to "false" and the ScrollView workks fine in Vertical.
wrap your scrollview like this
<ScrollView horizontal={true}>
<View style={styles.bottomBox} />
<View style={styles.bottomBox} />
<View style={styles.bottomBox} />
</ScrollView>
bottomBox : {
width: 40,
height: 125,
backgroundColor: 'steelblue',
padding: 5,
marginRight: 10,
}

I tried a lot to find out what is wrong with this. But i was unable to do so. Can someone help me to find out a solution to this problem ?. If someone can help me it is really really appreciated as I am completely help less with this.Thank you
I have a View (containing an Icon and Text, to act as a big checkbox) which is placed above a ScrollView, however, the ScrollView is appearing in front of the View, and also the Text isn't displaying.
I've tried every combination of flex, sometimes ending up with both of them taking up half the screen.
The Icon/Text works fine on other screens.
this shows the view behind the scrollview, rather than neatly above it, with some margin.
this is what it looks like on another screen, fine with margins, etc.
export default StyleSheet.create({
container: {
flex: 1,
alignItems: 'center',
marginTop: 20,
marginBottom: 20,
backgroundColor: 'white',
},
scrollview: {
width: '100%',
paddingTop: 10,
paddingBottom: 10,
},
heading: {
fontSize: 36,
textAlign: 'center',
marginLeft: 20,
marginRight: 20,
},
subheading: {
fontSize: 20,
textAlign: 'center',
marginLeft: 20,
marginRight: 20,
},
});```
<View style={ style.container }>
<Text style={ style.heading }>{ this.state.list && this.state.list.name || 'My Gift List' }</Text>
{ this.state.list.date ? <Text style={ [ style.subheading, { marginTop: 5, marginBottom: 10 } ] }>{ formatDate( dateFromIso( this.state.list.date ), "%A %eth %B, %Y" ) }</Text> : null }
<View style={{ flex: 1, flexDirection: 'row', justifyContent: 'center', alignItems: 'center', marginTop: 10, marginBottom: 20 }}>
<Checkbox icon={ this.state.showTicked ? 'check' : null } onPress={ () => this.setState( { showTicked: ! this.state.showTicked } ) } />
<Text style={{ marginLeft: 10 }} onPress={ () => this.setState( { multiple: ! this.state.multiple } ) }>I would like more than one</Text>
</View>
{
this.state.list.items.length > 0 ?
<ScrollView style={ style.scrollview } >
<FlatList style={ { marginTop: 10, marginBottom: 50, width: "100%", borderTopColor: '#ddd', borderTopWidth: 1 } } data={ this.state.list.items } renderItem={ this.renderItem } />
</ScrollView>
: null
}
</View>```
const Checkbox = args => {
const props = Object.assign( {}, args );
props.containerStyle = Object.assign( { width: 40 }, props.containerStyle || {} );
props.buttonStyle = Object.assign( { backgroundColor: 'transparent', borderWidth: 1, borderColor: '#555', height: 40 }, props.buttonStyle || {} );

};
I think You just need to change the z index for the scroll view and the regular view in the style sheet
export default StyleSheet.create({
container: {
zIndex: 2,
flex: 1,
alignItems: 'center',
marginTop: 20,
marginBottom: 20,
backgroundColor: 'white',
},
scrollview: {
zIndex: 1,
width: '100%',
paddingTop: 10,
paddingBottom: 10,
},
heading: {
fontSize: 36,
textAlign: 'center',
marginLeft: 20,
marginRight: 20,
},
subheading: {
fontSize: 20,
textAlign: 'center',
marginLeft: 20,
marginRight: 20,
},
});```
I can't get my app to fill the whole screen. Whatever i do, there is always a white bar on the bottom of the page. It's so strange because it works on some devices but not others. i'm going crazy over this!
Ive tried const { height, width } = Dimensions.get('window'); and setting the app height with that, and it actually worked once, but now i can't get it to work again. ive tried rewrapping everything in different ways, with different views and scrollviews.
ps.: i removed all functions and useless code so it's not too much code, but
here is my code

I think you're talking about the image background but not totally sure. I was able to get it to stretch to the full height by adding the following height declaration:
imagemBackground: {
flex: 1,
height: height,
},

You are using flex:1 many times in style that is the problem.
please give flex:1 in container style and remove all flex:1 in other styles instead of flex:1 you can use width and height in percentage.
like style={{width:'100%',height:'40%'}}.
Thank you!
