I have this <ScrollView />
<ScrollView
style={styles.scrollview}>
{route.params && route.params....map((cat, index) => {
return <Kitten
cat={cat}
key={index} />
})}
</ScrollView >
const styles = StyleSheet.create({
scrollview: {
paddingLeft: 15,
paddingRight: 15,
backgroundColor: 'white',
flex: 1,
},
});
into which I want to put this <BackgroundImage />.
import { ImageBackground } from 'react-native';
const image = require('...')
const Kittens = ({ children }) => {
return <ImageBackground
source={image}
resizeMode='repeat'
style={{ width: '100%', height: '100%' }}>
{children}
</ImageBackground>
}
I want the background image to be fixed, so that the content scrolls over the image. I further shall fill the whole screen. How would I do that?
use the scrollview as the child of ImageBackground
<ImageBackground
source={{uri://image url here}}
style={{
}}
>
<ScrollView
style={styles.scrollview}
contentContainerStyle={}
>
{route.params && route.params....map((cat, index) => {
return <Kitten cat={cat} key={index} />
})}
</ScrollView >
</ImageBackground>
If the parent of the Kittens fills the screen, removing white backgroundColor should work. You can play with resizeMode to get the best result from your image.
<Kittens>
<ScrollView
style={styles.scrollview}>
{route.params && route.params....map((cat, index) => {
return <Kitten cat={cat} key={index} />
})}
</ScrollView >
</Kittens>
const styles = StyleSheet.create({
scrollview: {
paddingLeft: 15,
paddingRight: 15,
//backgroundColor: 'white',
flex: 1,
},
});
<ImageBackground
source={{uri:image url}}
style={{height:"100%", width:"100%"}}
>
<ScrollView
contentContainerStyle={flexGrow:1}
>
<View style={{flex:1}} >
</View>
</ScrollView >
</ImageBackground>

The code below shows how all the functions are implemented
On iOS everything works fine, the button changes slide, the dots on the bottom change state based on the page and on the last page it displays a signup button,
On Android, the button works only on the first page, the last page doesnt show the signup button, and next button doesnt work on the second page!
export default function introScreen({ navigation }) {
const [sliderState, setSliderState] = useState({ currentPage: 0 });
const scrollRef = useRef();
const { width, height } = Dimensions.get('window')
const notchSize = StatusBar.currentHeight
const setSliderPage = (event: any) => {
const { currentPage } = sliderState;
const { x } = event.nativeEvent.contentOffset;
const indexOfNextScreen = Math.floor(x / width);
if (indexOfNextScreen !== currentPage) {
setSliderState({
...sliderState,
currentPage: indexOfNextScreen,
});
}
};
const { currentPage: pageIndex } = sliderState;
const onPressTouch = () => {
scrollRef.current?.scrollTo({
x: width*(pageIndex+1),
animated: true,

I have narrowed down the problem to the width and the 'event.nativeEvent.contentOffset', the returning number is close to 1 but it is (0.9), therefor math.floor was giving 0 as the index number,
I have changed Math.floor to Math.round and it is working perfectly fine,
If anyone wants a Introduction Slider for their app they can use this
I have 2 columns in flatList and I'm trying to align the header component besides the items itself,
Like this
But I got the "add image" above then the items below it,
I'm trying to solve it by using flexWrap in content container style but since I was using numColumns i got a warning that tells flexWrap not supported and use numColumns instead.
so i don't know how can i solve it, so if anybody can help in this case!
here's a snack
Code snippet
const renderItems = ({ item, index }) => {
return (
<View style={{ flex: 0.5, margin: 4 }}>
<View style={[styles.imgContainer, { borderWidth: 0 }]}>

}}
/>
</View>
</View>
);
};
const renderHeader = () => (
<TouchableOpacity
// onPress={appeandImgs}
style={styles.imgContainer}>
<Image

I am using a thumbnail where the cross is transparent and takes the background color of the main container. I want the cross to be white.
export const FriendDetailsScreen: React.FunctionComponent = () => {
const navigation = useNavigation();
return (
<SafeAreaView style={styles.safeAreaViewContainer}>
<View style={styles.container}>
<View style={styles.iconsContainer}>
<TouchableOpacity
style={styles.cross}>
<Thumbnail
source={{
uri:
'https://cdn0.iconfinder.com/data/icons/very-basic-android-l-lollipop-icon-pack/24/close-512.png',
}}
/>
</TouchableOpacity>
</View>
</View>
</SafeAreaView>
);
};
export const styles = StyleSheet.create({
safeAreaViewContainer: {
flex: 1,
},
container: {
backgroundColor: '#323443',
flex: 1,
},
cross: {
paddingTop: moderateScale(30),
paddingLeft: moderateScale(20),
zIndex: 100,
},
});
If I add a background color to cross or the TouchableOpacity a block of white appears which goes beyond the thumbnail. How else can I achieve this?
Thumbnail:
https://cdn0.iconfinder.com/data/icons/very-basic-android-l-lollipop-icon-pack/24/close-512.png
Have you tried passing in a style prop to thumbnail like this?
export const FriendDetailsScreen: React.FunctionComponent = () => {
const navigation = useNavigation();
return (
<SafeAreaView style={styles.safeAreaViewContainer}>
<View style={styles.container}>
<View style={styles.iconsContainer}>
<TouchableOpacity
style={styles.cross}>
<Thumbnail
style={styles.thumbnail}
source={{
uri:
'https://cdn0.iconfinder.com/data/icons/very-basic-android-l-lollipop-icon-pack/24/close-512.png',
}}
/>
</TouchableOpacity>
</View>
</View>
</SafeAreaView>
);
};
export const styles = StyleSheet.create({
safeAreaViewContainer: {
flex: 1,
},
container: {
backgroundColor: '#323443',
flex: 1,
},
cross: {
paddingTop: moderateScale(30),
paddingLeft: moderateScale(20),
zIndex: 100,
},
thumbnail: {
backgroundColor: '#323443'
}
});
Lets say i have <ListingCard/> components inside of a
<ScrollView/> .
What i want is render those <ListingCard/> side by side on a container class.
Here is What i have tried so far:
<ListingCard/>
const ListingCard = (props) => {
return (
<View style={styles.container}>
<Text>This is ListingCard Component</Text>
</View>
);
};
const styles = StyleSheet.create({
container: {
//flex: 1,
alignItems: 'center',
justifyContent: 'center',
height: 150,
width: Dimensions.get('window').width / 2 - 6,
backgroundColor: colors.WHITE,
borderRadius: 5,
marginHorizontal:10,
marginBottom: 10
},
});
export default ListingCard;
here is how i used <ListingCard/> :
render() {
const { currentCategory } = this.state;
return (
<Drawer
ref={(ref) => this._drawer = ref}
type="static"
onOpenStart={() => {
this.setState({
isDrawerOpen: true,
})
}}
onClose={() => {
this.setState({
isDrawerOpen: false,
})
}}
content={<SideFilterMenu />}
tapToClose={true}
side={'right'}
openDrawerOffset={0.2} // 20% gap on the right side of drawer
panCloseMask={0.2}
closedDrawerOffset={-3}
>
<View style={styles.container}>
<CustomHeader
onPress={() => this.handleFilterPress()}
headerText={currentCategory && currentCategory.categoryName}
isIconVisible={true}
rightButtonText={'Filtrele'}
onIconPress={() => this.handleBackPress()}
/>
<ScrollView
style={{flex:1}}
contentContainerStyle={styles.cardContainer}
>
<ListingCard />
<ListingCard />
<ListingCard />
<ListingCard />
<ListingCard />
<ListingCard />
<ListingCard />
<ListingCard />
</ScrollView>
</View>
</Drawer>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
//alignItems: 'center',
//justifyContent: 'center',
backgroundColor: colors.GENERAL_BCK,
//paddingHorizontal: 5
},
cardContainer: {
flexDirection: 'row',
flexWrap: 'wrap'
}
});
What i have tried is, with or without <View> container but this isnt helped at all. The reason i could not accoplish it is i am relatively new on ReactNative and have struggle with those stylings.
I could not accomplish to render those <ListingCard/> side by side. Any help will be appreciated, thanks.
Ok, i have fixed it.
Problem was <ListingCard/>'s width.
it was: width: Dimensions.get('window').width / 2 - 6, which was too wide to fit two of them on same row. so i changed it to: width: Dimensions.get('window').width / 2 - 20, and voila! it's worked.
I have a component called MDropDowlList which render the following view :
MDropDownList.js
render() {
return (
<View>
<View
style={{
backgroundColor: '#fff',
position: 'absolute',
left: 0,
right: 0,
top: 0,
maxHeight: 200,
}}
>
{
this.props.searchable && (
<TextInput
style={{ zIndex: 198 }}
onChangeText={(text) => this.search(text)}
/>
)
}
<FlatList
data={this.state.data}
keyboardShouldPersistTaps="always"
nestedScrollEnabled={true}
contentContainerStyle={{ zIndex: 199 }}
keyExtractor={(item, index) => index.toString()}
renderItem={({ item, index }) => (
<TouchableHighlight
key={index.toString()}
style={{
padding: 10,
backgroundColor: '#fff',
}}
underlayColor="#5897fb"
onPress={() => this.props.handleOnPress(item)}
>
<MText size={18}>{item}</MText>
</TouchableHighlight>
)}
/>
</View>
</View>
);
}
Then I have called this component to another component called MDropDown which render method is as below :
MDropDown.js
render() {
return (
<View style={{ marginVertical: 5, zIndex: 3}}>
...
{/* Another components */}
...
{
this.state.displayDropDown && (
<MDropDownList data={this.props.data} searchable={this.props.searchable} handleOnPress={(item) => this.handleOnPress(item)} />
)
}
</View>
);
}
Now finally I called my MDropDown component in my main screen as follow :
render() {
return (
<KeyboardAvoidingView style={{ flex: 1, backgroundColor: Colors.bgGray }} behavior="padding">
<ScrollView showsVerticalScrollIndicator={false} contentContainerStyle={styles.container} keyboardShouldPersistTaps="always" nestedScrollEnabled={true}>
<View style={{ backgroundColor: '#fff', padding: 10 }}>
<MDropDown
label="Category"
placeholder="Select Category"
data={["test1", "test2", "test3", "test4", "test5"]}
onSelectItem={(selectedItem) => alert(selectedItem)}
searchable={true}
/>
</View>
</ScrollView>
</KeyboardAvoidingView>
)
}
But I am not able to access Flatlist item or TextInput of MDropDownList component. Even I am not able to focus TextInput available in MDropDownList.
Please help me what's going wrong here ???
Note : This issue is only on android, on ios it is working properly. On ios I am able to click flatlist item and focus TextInput as well as.
Tried using zIndex to the absolute view?
Add property of zIndex : 500 to the style.
