To work properly this component requires that a fixed-size content container be specified through the contentContainerStyle prop.
import ScrollView, { ScrollViewChild } from 'react-native-directed-scrollview';
...
export default class Example extends Component {
render() {
return (
<ScrollView
bounces={true}
bouncesZoom={true}
maximumZoomScale={2.0}
minimumZoomScale={0.5}
showsHorizontalScrollIndicator={false}
showsVerticalScrollIndicator={false}
contentContainerStyle={styles.contentContainer}
style={styles.container}
>
<ScrollViewChild scrollDirection={'both'}>
// multi-directional scrolling content here...
</ScrollViewChild>
<ScrollViewChild scrollDirection={'vertical'}>
// vertically scrolling content here...
</ScrollViewChild>
<ScrollViewChild scrollDirection={'horizontal'}>
// horizontally scrolling content here...
</ScrollViewChild>
</ScrollView>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
},
contentContainer: {
height: 1000,
width: 1000,
},
})See the example project for more detail.
