FlatList numColumns not working correctly?
I'm trying to use a FlatList to show a bunch of custom avatars to someone in a grid format, but it looks very strange and I can't figure out how to fix it.
This is how my FlatList code looks like:
<FlatList style={{flex: 1}} data={this.props.usersList} horizontal={false} numColumns={3} columnWrapperStyle={{ marginTop: 10 }} renderItem={({ item }) => this.renderItem(item)} keyExtractor={this._keyExtractor}/>
and this is what the component for renderItem looks like:
class UserButton extends React.Component {
render() {
const { item, onPress } = this.props;
return (
<TouchableOpacity style={styles.button} onPress={onPress}>
<Image
source={(item.avatar) ? { uri: item.avatar } : require('../assets/images/userplaceholder.png')}
resizeMode='cover'
style={styles.imageStyle}
/>
</TouchableOpacity>
)
}
const styles = {
button: {
height: 100,
width: 100,
borderColor: '#aaa',
backgroundColor: '#aaa',
borderWidth: 2,
borderRadius: 50,
justifyContent: 'center',
alignItems: 'center',
marginHorizontal: 5,
},
imageStyle: {
height: 96,
width: 96,
alignSelf: 'center',
borderRadius: 48,
marginTop: (Platform.OS == 'android') ? 0 : 0.4
}
}
export default UserButton;
Does anyone have any idea?

I was in a similar situation, but now I have the correct grid using flatList, you can take a look at my code below.
<FlatList
contentContainerStyle={{margin:4}}
horizontal={false}
numColumns={4}
data={this.state.categoryDataSource}
renderItem={(categoryItem) =>
<CategoryListItem category={categoryItem.item} mode="small"/>
}
keyExtractor={category => category.id}
/>
