in iOS, a white line will appear when pulling up the <ScrollView> with refreshControl, anyone knows the reasons?
<ScrollView
removeClippedSubviews={true}
showsVerticalScrollIndicator={false}
refreshControl={
<RefreshControl
refreshing={props.listViewState.pullToRefresh}
onRefresh={handleOnRefresh}
/>
}
contentContainerStyle={{backgroundColor: 'white'}}
>
<View> ... </View>
<View> ... </View>
</ScrollView>
white line appears
I had the same issue with Flatlist.
Try something like this.
return (
<SafeAreaView style={styles.container}>
<View style={styles.container2}/>
<FlatList
data={DATA}
renderItem={renderItem}
keyExtractor={item => item.id}
contentContainerStyle={{ backgroundColor: 'white' }}
ListHeaderComponent={<View>
<Text style={{backgroundColor:'#293541'}}>HEADER</Text></View>}
refreshControl={
<RefreshControl
refreshing={refreshing}
onRefresh={onRefresh}
tintColor={'red'}
backgroundColor={'#293541'}
/>
}
/>
</SafeAreaView>
);
and for styling :
container: {
flex:1,
marginTop: StatusBar.currentHeight || 0,
backgroundColor: 'white',
},
container2: {
position: 'absolute',
top: 0,
left: 0,
width: '100%',
height: '60%',
backgroundColor: '#293541',
},

I'm trying to show a flatList in tvOS and when the flatlist is rendered it shows unwanted space at the top of the rendered items inside the flatlist. This issue is not happening in Android TV or Fire TV.
My code :
<SafeAreaView
style={{
flex: 1,
backgroundColor: Colors.APP_BACKGROUND,
flexDirection: 'row',
}}>
<View style={{width: '27%'}}>
<View
style={[{flex: 1, marginLeft: Platform.OS === 'android' ? '10%' : '5%', marginRight: '10%', marginTop: '10%'}]}>
<Text
style={[
{
fontSize: FontSize.large,
color: Colors.WHITE,
fontFamily: FontFamily.bold,
marginBottom: '5%',
paddingHorizontal: ms(10),
marginLeft: Platform.OS === 'android' ? ms(5) : ms(2),
},
]}>
Settings
</Text>
<FlatList
data={pages}
renderItem={({item, index}) => renderSettingItem(item, index)}
removeClippedSubviews={false}
/>
</View>
</View>
<View
style={{
backgroundColor: Colors.SEPARATOR_SETTING_PAGE,
width: 3,
marginTop: '2%',
height: '60%',
}}
/>
<View style={{width: '73%'}}>
<SettingPageComponent page={page} />
</View>
</SafeAreaView>
I don't know what I did wrong. I'd really appreciate some help. Thanks !
I am building a react native expo application. The backend is seperated and not used in the process. Below you ll see the home screen component returns
return (
<ImageBackground source={require("../assets/background.jpeg")} style={styles.background}>
<MainPageTopBar />
<View style={styles.container}>
<ScrollView>
<View style={styles.textArea}>
<Text style={styles.text} >Merhaba</Text>
</View>
<View style={styles.welcome}>
<MainCard text={"Tüm Sanatçıları Keşfet"}/>
</View>
<View>
<Text>Öne Çıkan Sahneler</Text>
<View>
<ScrollView horizontal={true}>
{
venueList.map((val, index) => {
return (
<StageCard stageName={val.name} stageLocation={val.location}/>
)
})
}
</ScrollView>
</View>
</View>
</ScrollView>
</View>
<AppBar />
</ImageBackground>
);
Likewise below u can see the code for the class StageCard
import { View, TouchableWithoutFeedback, StyleSheet, Text, ImageBackground } from "react-native";
import { Ionicons } from '#expo/vector-icons';
import React from "react";
function StageCard(props) {
const func = () => {
props.navigation.navigate(props.nav);
}
return (
<TouchableWithoutFeedback onPress={() => console.log("ola")}>
<View style={styles.container}>
<ImageBackground style={styles.stageCard} imageStyle={styles.imageStyle} source={require("../assets/venue.jpg")}>
<View style={styles.nameView}>
<Text style={styles.text}>
{props.stageName}
</Text>
</View>
<View style={styles.cityView}>
<Text style={styles.textCity}>
{props.stageLocation}
</Text>
</View>
</ImageBackground>
</View>
</TouchableWithoutFeedback>
);
}
const styles = StyleSheet.create({
container: {
width: "40%",
height: "30%",
marginLeft: "5%",
marginTop: "10%",
},
imageStyle: {
borderRadius: 20,
},
stageCard: {
width: '100%',
height: '100%',
flex: 1,
},
nameView: {
width: "50%",
height: "20%",
alignContent: "center",
backgroundColor: "transparent",
position: "absolute",
top: "5%",
left: "5%",
},
cityView: {
width: "50%",
height: "20%",
alignContent: "center",
backgroundColor: "transparent",
justifyContent: "flex-end",
position: "absolute",
bottom: "5%",
right: "5%",
},
text: {
textAlign: "left",
textAlignVertical: "center",
fontSize: 20,
color: "#f4eeeb",
borderColor: "#f4eeeb",
},
textCity: {
textAlign: "right",
textAlignVertical: "center",
fontSize: 20,
color: "#f4eeeb",
borderColor: "#f4eeeb",
},
})
export default StageCard;
The app crashes when the app is built. I have narrowed down the possibilities as when I changes the stagecard to a view, the app builds and runs too. Hence the issue must be in the StageCard component.
After coming to the prior conclusion, I tried seperatly isolating the component. Couldn't figure out what caused the issue on the ios.
Update: The problem is caused by the scrollview as the mapping separately works. I got rid of the scrollview horizontal and the cards showed up. Any ideas?
I am attempting to make the images scroll horizontally. I downloaded some UI, and added ScrollView horizontal. But instead of it looking the same just with the ability to scroll horizontally, it shrank the image (and also gave it the ability to scroll horizontally). What should I change to make it stretch all the way across (still with the padding)?

Here's me adding more words because the post doesn't have enough words on it's own. When will they finally remove this pointless feature? I feel as if I clearly expressed my question with the few words I used.
I believe your issue is with your View wrapping your ScrollView. There is no need of wrapping ScrollView, that too in row, due to which the remaining space is visible. Just define the ScrollView, and it would work just fine. Give a width of 100% to your ScrollView though.
For any sort of styling to the parent for the ScrollView, do it inside the ScrollView itself, like the way I did in the code.
Please note ScrollView accepts a list of child items, currently I see only a single item, if you've intentionally added this one, then it is fine, else, you need to refactor your code surely. This won't work out for you.
// PLEASE NOTE --> Commented Lines should be removed, and
// only ScrollView should be considered with the styling specified

My code works fine on Most of iPhones but on Iphone 5 the status bar has been covered by the view, I don't know how to margin the view in Iphone 5 only if i used margin top in the view, it looks weird in other iPhones
componentWillMount() {
this.startHeaderHeight = 45
this.marginTopHeader = 0
this.iconMargin = 9
if (Platform.OS == 'android') {
this.startHeaderHeight = 30 + StatusBar.currentHeight
this.marginTopHeader = 23 + this.marginTopHeader
this.iconMargin = this.iconMargin
}
}
render() {
var width = Dimensions.get('window').width - 128;
var height = Dimensions.get('window').height;
return (
<SafeAreaView style={{
height: this.startHeaderHeight, flexDirection: 'row',
borderBottomColor: '#ddd', backgroundColor: '#3A3658', marginTop: this.marginTopHeader
}} >

You can try to write like this.
<View style={{flex: 1, backgroundColor: 'white'}} >
{/* header */}
<View style={{paddingTop: system.ios.x ? 22 : 0}}>
<View style={{
height: Platform.select({ios: 64, android: 44}),
backgroundColor: 'white',
justifyContent: 'flex-end'
}}>
`enter code here`
</View>
</View>
</View>
I am trying to use the KeyboardAvoidingView with behavior="padding".
When I am trying to enter any text in TextInput, the TextInput field is not moving up. I have added a small view in the end which is moving up but the the view above it.
I have also with KeyboardAvoidingView height property with offset. It was working few components like 2 TextInputs. But when I add all the components the UI goes insane and behave jumbled up.
Any any idea whats happening over here?
Here the link of tutorial which I have followed.
render() {
return (
<View style={styles.backgroundContainer}>
<Loader
loading={this.state.isLoading} />
<KeyboardAvoidingView
keyboardVerticalOffset={10}

<View style={[styles.centerContainer, { marginTop: 40 }]}>

<Text style={styles.loginMsg}> Login to your Account </Text>

I used KeyboardAvoidingView, it also doesn't work.
I found this solution, You can take the base code.
Installation
npm i react-native-keyboard-aware-scroll-view --save
Usage
import { KeyboardAwareScrollView } from 'react-native-keyboard-aware-scroll-view'
<KeyboardAwareScrollView>
<View>
<TextInput />
</View>
</KeyboardAwareScrollView>
You can find it here
The way it worked for me was to use position as behavior and -70 as vertical offset. Any non negative integer was creating a huge unused space when the keyboard pops up.
<KeyboardAvoidingView
style={styles.container}
behavior={Platform.OS === 'ios' ? 'position' : 'height'}
keyboardVerticalOffset={Platform.OS === 'ios' ? -70 : 70}
enabled>
<ScrollView>
...
</ScrollView>
</KeyboardAvoidingView>
<KeyboardAvoidingView
style={styles.mainContainer}
behavior="padding"
enabled
>
<View>.......................</View>
</KeyboardAvoidingView>
'Enabled or disabled KeyboardAvoidingView' should be add.
Keep in mind is always your top Parent with flex:1 then the child is then you text input container
<KeyboardAvoidingView style={{ flex: 1 }}
behavior={Platform.OS === "ios" ? "position" : null} enabled>
<ScrollView>
<View>
<View >
<Text maxFontSizeMultiplier={1.5} >
Sign in to your account{" "}
</Text>
<View
behavior="padding"
enabled
>
<TextInput
placeholder="Email address"
placeholderTextColor={Colors.grey}
style={styles.textInput}
onChangeText={(e) => setEmail(e.trim())}
autoCapitalize="none"
returnKeyType={"done"}
/>
</View>
</View>
</ScrollView>
</KeyboardAvoidingView>
// 2nd Solutions use this package
npm i react-native-keyboard-aware-scroll-view --save
import { KeyboardAwareScrollView } from 'react-native-keyboard-aware-scroll-view'
<KeyboardAwareScrollView>
<View>
<TextInput />
</View>
</KeyboardAwareScrollView>
