I Had this code with sticky component on the header, how can i move this to the bottom, like footer button on instagram (when you open the app, it already stick in the bottom) ? here's my code
function MyApp() {
return (
<ScrollView
stickyHeaderIndices={[0]}
showsVerticalScrollIndicator={false}>
<View>
<MyStickyFooter/>
</View>
<View>
<Text> Hello world </Text>
<Text> 3000 long lorem word </Text>
</View>
</ScrollView>)}
const MyStickyFooter = () => {
return (
<View style={{}}>
<Button> I am a sticky footer </Button>
</View>
)};
You should move out the MyStickyFooter component from your ScrollView.
You should have something like this:
<View style={....}>
<ScrollView>
... components
</ScrollView>
<MyStickyFooter/>
</View>

))}

</ScrollView>
)
}```
i used flex 1 on the view outside the map function and it didnt fix it
Remove the View above the ScrollView.
You try to set one child for the scrollView it’s the View component and the View component have array map.
Remove the View component to keep array map child for ScrollView
I have a horizontal flatlist inside a vertical flatlist and I want data on the inside flatlist to be provided based on which item of the outer flatlist is being rendered
This is what I have currently:
<FlatList
style={styles.outerFlatlist}
data={this.state.catagories}
renderItem={({item, index})=>{
return (
<View>
<View>
<Text style={styles.catagoryName}>
{item.CategoryName}
</Text>
</View>
<View style={styles.innerFlatlist}>
<FlatList
horizontal={true}
data={this.state.product1}
renderItem={({item, index})=>{
return (
<View
style={styles.productsContainer}>
<View
style={styles.productImage}>
<Image
source={{uri:item.productImage}}
style={styles.image}
resizeMode='contain'>
</Image>
</View>
<View style={styles.productDETAILS}>
<Text
style={styles.productPrice}>R{item.productPrice}
</Text>
<Text
style={styles.productDescription}>
{item.productDecription}
</Text>
</View>
</View>
);
}}/>
</View>
</View>
);
}}/>

<script src="https://cdnjs.cloudflare.com/ajax/libs/react-dom/16.6.3/umd/react-dom.production.min.js"></script>
With the above code, everything works well except that each category displays the same data (this.state.product1), how can I make the data of the inner flatlist be dependant on the which item on the outer flatlist is displayed?
When you are inside the .map you already are inside the this.state.catagories , but since you always use this.state.product1 for the flatlist2 you will always get the same result because this.state.product1 stays the same.
At flatlist2 change the data to item.products or item.whateverYouNeedHereButArray
<View style={styles.innerFlatlist}>
<FlatList
horizontal={true}
data={item}
I am doing react native application. In that, One screen have custom tabs in centre of the screen.
My screen is like,
top view around 200px height with some text lines showing.
After that, Custom tabs as picture attached.
After that, I am showing for first tab on tap flat list data.
I have checked online forums and tutorials, According to tab bar, We can show either top or bottom screen with tabs.
But, How to show tabs with customisation like my requirement.
I have 4 tabs, and each tab has same top view which I mentioned in above (some text lines), And if I tap on each tab, different data bottom page should show.
Like,
First tab with some flat list,
second tab with some text lines,
likewise all tabs has different layout in bottom screen.
As I am very new to react native. How to achieve this?
Due to privacy policy, I am unable to post complete screenshot.
Here is my code.
Screen.js
onClickTelugu = () => {
alert("you clicked onClickTelugu")
}
onClickTamil = () => {
alert("you clicked onClickTamil")
}
onClickHindi = () => {
alert("you clicked onClickHindi")
}
onClickEnglish = () => {
alert("you clicked onClickEnglish");
}
render(item) {
return (
<View style={styles.container}>
<View style ={styles.Container}>

<View style = {styles.flatListContainer}>
<FlatList style = {styles.flatList}
showsVerticalScrollIndicator = {true}
data = {this.state.dataArray}
renderItem = {({item}) => (
<TouchableWithoutFeedback onPress={ () => this.flatListItemHandler(item)}>
<Image

/>
</View>
<View style={styles.flatListItemInsideSeparator}>
)
}
ItemSeparatorComponent = {() => (
<View style={{height:15, backgroundColor:'#F8F8F8'}}/>
)}
/>
</View>
</View>
);
}
}
And I have to show overlay tab images too. If 1st tab tapped, 2,3,4
tabs images should be like delighted images. Like
highlighted/delighted images.
Ok you need to give this component it's own state to keep track of what you want to show in the lower section. then you should replace all of your onClick events with just one onClick event that you pass different languages to. For Example this.onClickTelugu becomes () => this.onClick('telugu'), then your onClick event should be:
onClick = (language) => {
this.setState({selectedLanguage: language})
}
then in your renderBottomContent function, you can render different things depending on what this.state.selectedLanguage is.
something like...
class MyComponent extends Component {
constructor(props) {
super(props)
this.state = { selectedLanguage: null}
}
onClick = (language) => {
this.setState({selectedLanguage: language})
}
renderBottomContent = () => {
const {selectedLanguge} = this.state
switch(selectedLanguage) {
case "telugu":
return <View><Text>Telugu</Text></View>
case "tamil":
return <View><Text>Tamil</Text></View>
case "hindi":
return <View><Text>Hindi</Text></View>
case "english":
return <View><Text>English</Text></View>
default:
return <View><Text>No Language Selected...</Text></View>
}
}
render() {
...
<View style ={styles.tabInnerContainer}>
<TouchableOpacity style={styles.tabIcons} onPress={() => this.onClick('telugu')}>
<Image style={styles.tabItemsImages} source={image} />
<Text style={styles.tabTextItems}>
Telugu
</Text>
</TouchableOpacity>
</View>
<View style ={styles.tabInnerContainer}>
<TouchableOpacity style={styles.tabIcons} onPress={() => this.onClick('tamil')}>
<Image style={styles.tabItemsImages} source={image} />
<Text style={styles.tabTextItems}>
Tamil
</Text>
</TouchableOpacity>
</View>
...
// after all the other tab buttons, render bottom content depending on the component state
{this.renderBottomContent()}
}
}
We have a FilterComponent which renders a Modal, but on iPhone X it's Header is in the Statusbar.
I tried to render it with SafeAreaView but seems like this is not working:
return (
<SafeAreaView>
<Modal
{ ...defaultModalProps }
onRequestClose={ close }
style={ styles.container }
visible={ visible }
>
<ModalNavbar close={ close }>
Filter
</ModalNavbar>
<View style={ styles.content }>
...
</View>
</Modal>
</SafeAreaView>
);
When FilterModal is openend on iPhoneX it still is in the Statusbar and you cant click on anything.
Any idea how to solve this?
thanks.
Put SafeAreaView inside the Modal component
return (
<Modal
{...defaultModalProps}
onRequestClose={close}
style={styles.container}
visible={visible}
>
<SafeAreaView style={{ flex: 1, backgroundColor: "transparent" }}>
<ModalNavbar close={close}>Filter</ModalNavbar>
<View style={styles.content}>...</View>
</SafeAreaView>
</Modal>
);
if you use react-native-safe-area-context and you have a problem with modal then
<Modal>
<SafeAreaProvider>
<SafeAreaView>
// your modal content
</SafeAreaView>
</SafeAreaProvider>
</Modal>
A Modal fill the entire screen, so you need to provide extra spacing inside the Modal. Margin / Padding will not effect on Modal if applied on parent of Modal.
<Modal {...}>
<TouchableWithoutFeedback onPress={closeModal}>
<SafeAreaView {...}>
{...}
</SafeAreaView>
</TouchableWithoutFeedback>
</Modal>
When I wrap content like this example below, it scrolls Perfectly..
return(
<ScrollView>
<Text> TEST </Text>
<Text> TEST </Text>
<Text> TEST </Text>
<Text> TEST </Text>
...
</ScrollView>
);
However, whenever I wrap it in another View, It will not scroll.
return(
<View>
<ScrollView>
<Text> TEST </Text>
<Text> TEST </Text>
<Text> TEST </Text>
<Text> TEST </Text>
...
</SCrollView>
</View>
);
Is there some sort of fix to this. I am trying to put a nav bar header above all of the content, couldn't really figure it out though.
It's a typo:
Your closing ScrollView tag is: </SCrollView> rather than </ScrollView>.
You also need to add a style to the View container, here's an example of what it should look like:
return(
<View style={{flex: 1}}>
<ScrollView>
<Text> TEST </Text>
<Text> TEST </Text>
<Text> TEST </Text>
<Text> TEST </Text>
...
</ScrollView>
</View>
);
Try next code:
<ScrollView contentContainerStyle={{ flexGrow: 1 }}>
<Text> TEST </Text>
<Text> TEST </Text>
<Text> TEST </Text>
<Text> TEST </Text>
</ScrollView>
If your ScrollView is within something that handles touch (Pressable, TouchableWithoutFeedback etc) then you either need to stop the touch event propagating up to that parent handler or else the ScrollView won't handle the touch event and therefore won't scroll.
This can be done either with onStartShouldSetResponder={() => true} or by wrapping the children in an element which itself handles the touch event (e.g. Pressable):
return (
<ScrollView>
<Pressable>
<Text>This is scrollable</Text>
<Pressable>
<Pressable>
<Text>As is this</Text>
<Pressable>
</ScrollView>
);
Try adding style={{flex:1}} to <View> and <ScrollView> components. You also have a typo on your code: </SCrollView> in line 9. An example code will look like this:
<View style={{backgroundColor:'white', flex:1}}>
<NavigationBar title="Title" />
<ScrollView style={{flex:1, backgroundColor:'white'}}>
<View style={{flex:1,justifyContent:'center'}}>
<RegisterForm />
</View>
</ScrollView>
</View>
Another solution is to add a height property to the parent View container. This sometimes works well when calculating the height against the screen height.
render () {
const screenHeight = Dimensions.get('window').height
return(
<View style={{height: screenHeight}}>
<ScrollView>
<Text> TEST </Text>
<Text> TEST </Text>
<Text> TEST </Text>
<Text> TEST </Text>
...
</ScrollView>
</View>
)
}
I have tried all of these solutions and none were working. Then I just fully restarted the app and the metro server and everything worked fine.
As #Evan Siroky has answered above it's working well I'm just adding on thing for a auto height in case you don't want to reserve the space
render () {
const screenHeight = Dimensions.get('window').height
return(
<View style={{ Height: "auto", maxHeight: screenHeight}}>
<ScrollView>
<Text> TEST </Text>
<Text> TEST </Text>
<Text> TEST </Text>
<Text> TEST </Text>
...
</ScrollView>
</View>
)
}
I had a similar issues, it got solved by removing height/width if set to '100%'.
Just adding here if someone faces the same issues. :D
Set nestedScrollEnabled as true for Hybrid Android + react app as it might be issue with gesture/click for scrolling issue.
Just if anyone is as desperate as I was:
My view was inside a StackNavigator. In the StackNavigator you can assign a default cardStyle. This card style needs height: "100%".
For me this was the case but I had overwritten it within the cardStyle of the Stack.Screen definition.
See this working example:
// This is the stack navigator
<ModalStack.Navigator screenOptions={() => ({
cardStyle: {height: "100%"}
});}}>
<ModalStack.Screen name={ScreenItemDetail} options={{
// cardStyle: {} be sure to not override card style again!
}} component={ItemDetailScreen} />
// ...
</ModalStack.Navigator>
removing contentContainerStyle prop from the ScrollView has fixed the issue for me
Just add ScrollView as parent View if it's still not working for you...just restart your app or server and your ScrollView will work fine. Because sometimes our app freezes for no reason.
I think the best way of doing this is to put all requires inside an array and map this array.
const images = [
require('../your/path/here'),
require('../other/image/here'),
...
];
return ( {images.map((image) => <Image ... source={image} />)
note that if you want it as a background image with other elements above the image, you may use BackgroundImage and either render elements for each image or position absolute the image map and zIndex it behind all things
