Fetch data from API using flatlist in React Native - javascript

I'm trying to display data for a specific ID. Since my data is an array. I used flatlist to display it. It displays the data but it's displaying all ID. How I can solve this issue. Anyone can help with this?

}
This was the output.
I kept searching for this but couldn't find an answer that will make this clear.
Thanks!

React-Native FlatList is not scrolling

I am quite new to react native. I have created a FlatList for rendering this list of items, however, it is not scrolling. I've googled it for hours and tried nearly everything suggested in stack overflow threads - removed flex, added flex, wrapped it in a view, but nothing seems to work.
Here is my code (the issue is in the second FlatList) -
return(
<View style = {{ height: '100%' }}>
<View style = {{ width: '100%' }}>
<AppHeader />
</View>
<View style = {{ width: '100%'}}>
<View style = {{ width: '70%', alignSelf: 'center', flex: 1 }}>
<View>
<FlatList
data = {this.getTodayDay()}
renderItem = {this.renderItemDays}
keyExtractor = {this.keyExtractor}
/>
</View>
<FlatList
data = {this.getVisibleHours()}
renderItem = {this.renderItem}
keyExtractor = {this.keyExtractor}
scrollEnabled = {true}
/>
</View>
</View>
</View>
this.renderItem -
renderItem = () => {
// irrelevant code
if( isClass === true ){
return(
<ListItem bottomDivider = {true} style = {styles.renderItemActiveClass}>
<ListItem.Content>
<TouchableOpacity
onPress = {()=>{
this.props.navigation.navigate('ClassDetailsScreen', { "data": classData })
}}>
<ListItem.Title>{ definiteClassTime }</ListItem.Title>
<ListItem.Subtitle>{ classData.class_name }</ListItem.Subtitle>
</TouchableOpacity>
</ListItem.Content>
</ListItem>
)
}
else{
return(
<ListItem bottomDivider = {true} style = {styles.renderItemClass}
containerStyle = {styles.renderItemContent}>
<ListItem.Content>
<ListItem.Title>{item}:00</ListItem.Title>
<ListItem.Subtitle>No Class</ListItem.Subtitle>
</ListItem.Content>
</ListItem>
)
}
}
the StyleSheet -
renderItemClass: {
borderColor: 'purple',
borderWidth: 2
},
renderItemActiveClass: {
borderColor: 'green',
borderWidth: 2
},
renderItemContent: {
},
Could somebody please tell me what I'm doing wrong?

Add a height to both the flatlist. And also wrap your second flatlist within a seperate view. Here is an example:
return (
<View style={{ height: "100%" }}>
<View style={{ width: "100%" }}>
<AppHeader />
</View>
<View style={{ width: "100%" }}>
<View style={{ width: "70%", alignSelf: "center", flex: 1 }}>
<View style={{ height: 60, alignSelf: "center" }}>
<FlatList
data={this.getTodayDay()}
renderItem={this.renderItemDays}
keyExtractor={this.keyExtractor}
/>
</View>
<View style={{ height: 60, alignSelf: "center" }}>
<FlatList
data={this.getVisibleHours()}
renderItem={this.renderItem}
keyExtractor={this.keyExtractor}
scrollEnabled={true}
/>
</View>
</View>
</View>
</View>
);

How can I collapse Item pressed on arrays - react native?

I have a list of cards,
when pressed to any of them, I want to Increase hight for that card,
So I use layoutAnimation to handle this case because when I use Animated API from RN, I got an error when setNativeDrive "height"
Anyway,
In my case, it increases height for every card in the list,
So how can I solve it?
Code snippet
Live Demo
const OpenedAppointments = ({slideWidth}) => {
const [currentIndex, setCurrentIndex] = React.useState(null);
const [cardHeight, setCardHeight] = useState(140);
const collapseCard = (cardIndex) => {
setCurrentIndex(cardIndex);
currentIndex === cardIndex
? (LayoutAnimation.configureNext(LayoutAnimation.Presets.easeInEaseOut),
Animated.spring(),
setCardHeight(200))
: (LayoutAnimation.configureNext(LayoutAnimation.Presets.easeInEaseOut),
Animated.spring(),
setCardHeight(140));
};
const renderItems = (item, index) => {
return (
<TouchableOpacity
delayPressIn={0}
onPress={() => collapseCard(index)}
key={item.id}>
<Animated.View
style={[
styles.itemContainer,
{
height: cardHeight,
},
]}>
<View style={styles.headerContainer}>
<View style={styles.imgContainer}>
<Image
resizeMode="cover"
style={styles.img}
source={{uri: item.vendorInfo.vendorImg}}
/>
</View>
<View style={{width: '80%'}}>
<View style={styles.titleContainer}>
<Text numberOfLines={1} style={styles.vendorName}>
{item.vendorInfo.name}
</Text>
<View style={{flexDirection: 'row', alignItems: 'center'}}>
<Text style={styles.rateText}>{item.vendorInfo.rate}</Text>
<AntDesign name="star" size={18} color="#262626" />
</View>
</View>
<View style={styles.socialContainer}>
<View
style={{
width: 32,
height: 32,
backgroundColor: '#000',
borderRadius: 5,
}}
/>
</View>
</View>
</View>
<View style={styles.footer}>
<Text style={styles.serviceName}>
{item.serviceName}
</Text>
<Text style={styles.price}>
{item.price}
</Text>
</View>
// this will appeared when pressed to card "Footer Card"
<View>
<View style={styles.line} />
<View style={styles.editFooter}>
<View style={styles.dateContainer}>
<MemoCalender
style={styles.calenderIcon}
size={26}
color="#000"
/>
<View style={styles.dateBox}>
<Text style={styles.dateText}>{item.date}</Text>
<Text style={styles.dateText}>{item.time}</Text>
</View>
</View>
</View>
</View>
</Animated.View>
</TouchableOpacity>
);
};
return(
<>
{Data.opened.map((item, index) => renderItems(item, index))}
</>
);
}

Change this:
<Animated.View
style={[
styles.itemContainer,
{
height: cardHeight,
},
]
>
{...}
</Animated.View>
by
<Animated.View
style={[
styles.itemContainer,
{
height: currentIndex === index ? cardHeight : 140,
},
]
>
{...}
</Animated.View>
If you want to be more efficient, the default height of your card, define it in a constant (ex: const = DEFAULT_CARD_HEIGHT = 140) and use this constant wherever you use 140 as card height

Unable to show multiple images in react native

I am working on a react native application. I have to show multiple images. My code is:
render() {
if (!this.props.data) {
return(<Text style={styles.noIMG}>Keine Bilder vorhanden</Text>)
}
return (
<View>
<View style={styles.view}>
{
(
this.props.data == '' ||
this.props.data == null ||
this.props.data == undefined
) ? null :
this.props.data.map(img => {
console.log(img.image);
console.log("Image displayed");
return(
<TouchableHighlight
key={this.uuidv4()}
onPress={()=>{
this.setState({zoom: img.image})
}}
>
<Image
style={styles.imagePreview}
source={{uri: img.image}}
/>
</TouchableHighlight>)
})
}
</View>
{ this.state.zoom ?
<Card>
<PinchZoomView scalable={false}>
<FitImage resizeMode="contain" source={{uri: this.state.zoom}}/>
</PinchZoomView>
<TouchableOpacity
style={styles.btn}
onPress={() => this.deleteImage(this.state.zoom)}>
<Text style={{color:'white'}}>Delete Image</Text>
</TouchableOpacity>
</Card> :
<View style={styles.container}><Text>Bild zum vergrößern antippen.</Text></View>
}
</View>
);
}
I do get two images in "props.data" but on screen only one image is displayed. The css code is:
const styles = StyleSheet.create({
imagePreview:{
width: 100,
height: 100,
margin: 5
}
});

render() {
return (
<View style={{ flex: 1, flexDirection:'row'}}>
{data.map((value, i) => {
return (
<View key={i}>
<TouchableOpacity>
<Image
source={{ uri: value.imageUrl }}
style={{ width: 50, height: 50 }}
resizeMode={"stretch"}
/>
</View>
</TouchableOpacity>
);
})}
</View>
);
}

Try using a FlatList
<FlatList
data={this.props.data}
extraData={this.state}
renderItem={({ item }) => {
return (
<View>
<TouchableOpacity onPress={() => this.setState({zoom: img.image})}>
<Image
source={{ uri: item.image }}
PlaceholderContent={<ActivityIndicator />}
/>
</TouchableOpacity>
</View>
)
}}
keyExtractor={(item, index) => index.toString()}
/>

Where to implement my function when using map for iteration?

I'm loading code in the render method. If I write the function imageRemoveButtonClicked outside render method, it's giving an error saying that 'Cannot read property bind of undefined'. Don't know what to do. Can some one please help me in this.

Use arrow functions and class property feature. For more information about binding patterns read this article. Try to add your method as:
export class App extends Component {
yourMapFunction = () => {
yourCode...
}
}

I believe the problem is that you are not using an arrow function as the argument to this.state.selectedImages.map(). If you want to access this inside an inner function, you should use the arrow function syntax. The standard syntax does not capture this.
this.state.selectedImages.map((name, index) => {
return (...);
})
