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

styles.itemContainer,
{
height: cardHeight,
},
]}>

<Text style={styles.price}>

// this will appeared when pressed to card "Footer Card"

</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

I have a Sign Up screen in React Native, and when I press on the Input fields, my view does not go up therefore I can not see what I am typing. On other screens I have, the view gets pushed up. It feels like on Sign Up screen the "keyboardLayout" is set to "pan", but I did not specify it anywhere...
I am using Expo.

you can either use KeyboardAvoidingView or make a custom keyboard avoiding view yourself.
also when using KeyboardAvoidingView dont forget to specify the behavior prop.
here is an example of custom keyboard avoiding view
import React, { useEffect, useRef } from 'react';
import { Keyboard, KeyboardEvent, Animated, Platform } from 'react-
native';
import { heightPercentageToDP as hp } from 'react-native-responsive-screen';
function CustomKeyboardAvoidingView(props: any) {
const heightAnim = useRef(new Animated.Value(hp('100%'))).current
function onKeyboardDidShow(e: KeyboardEvent) {
Animated.spring(heightAnim, {
toValue: hp('100%') - e.endCoordinates.height,
overshootClamping: true,
bounciness: 1,
speed: Platform.OS == 'ios'? 18 : 50,
useNativeDriver: false,
}).start()
}
function onKeyboardDidHide() {
Animated.spring(heightAnim, {
toValue: hp('100%'),
overshootClamping: true,
bounciness: 5,
speed: Platform.OS == 'ios'? 18 : 50,
useNativeDriver: false,
}).start()
}
useEffect(() => {
const SHOW_KEYBOARD_EVENT = Platform.OS === 'ios' ? 'keyboardWillShow' : 'keyboardDidShow'
const HIDE_KEYBOARD_EVENT = Platform.OS === 'ios' ? 'keyboardWillHide' : 'keyboardDidHide'
const showSubscription = Keyboard.addListener(SHOW_KEYBOARD_EVENT, onKeyboardDidShow);
const hideSubscription = Keyboard.addListener(HIDE_KEYBOARD_EVENT, onKeyboardDidHide);
return () => {
showSubscription.remove();
hideSubscription.remove();
};
}, []);
return (
<Animated.View style={[{
height: heightAnim,
}]} >
{props.children}
</Animated.View>
)
}
I managed to solve it with the following way:
<KeyboardAvoidingView>
<ScrollView>
{*Rest of the code*}
</ScrollView>
</KeyboardAvoidingView>
I honestly dont know why, but this moves up my view when I want to type.
I am using flatlist for show user input notes in my app. But Flat List is not render any item that i entered. I used static list for testing and it works correctly. but when i enter a text through textinput it is not showing.
const addToDoHandler = () => {
if(userInput == ''){
return;
}
const newTodo = {
id: Math.floor(Math.random() * 1000),
text: userInput,
completed: false,
};
const newTodos = [...todos, newTodo];
setTodos(newTodos);
//clear user input
setUserInput('');
};
const renderItem = ( {item} ) => {
<View style={{backgroundColor:'#6b4d87', marginVertical: 10, flexDirection:'row', alignItems:'center', justifyContent:'space-between', height:60, width:'95%', borderRadius:10 }}>
<View>
<Text style={{color:'black', fontSize:20, fontWeight:'bold'}}>{item.text}</Text>
</View>
<TouchableOpacity onPress={() => deleteHandler(item.id)}>
<TrashIcon size={35} name="trash" style={{color:'#eff9f0'}} />
</TouchableOpacity>
</View>
};
return (
<SafeAreaView style={styles.root}>
<View style={styles.txtInputView}>
<TextInput
value={userInput}
onChangeText={text => setUserInput(text)}
style={styles.textInput}
placeholder={"Enter Your Note..."}
/>
<TouchableOpacity style={styles.addButton} onPress={addToDoHandler}>
<PlusSign size={35} name="add-sharp" style={styles.plusIcon}/>
</TouchableOpacity>
</View>
<View style={{alignItems:'center'}}>
<FlatList
data={todos}
renderItem={renderItem}
keyExtractor={item => item.id}
/>
</View>
</SafeAreaView>
);
You need to return the components from renderItem.
Change it to:
const renderItem = ( {item} ) => (
<View style={{backgroundColor:'#6b4d87', marginVertical: 10, flexDirection:'row', alignItems:'center', justifyContent:'space-between', height:60, width:'95%', borderRadius:10 }}>
<View>
<Text style={{color:'black', fontSize:20, fontWeight:'bold'}}>{item.text}</Text>
</View>
<TouchableOpacity onPress={() => deleteHandler(item.id)}>
<TrashIcon size={35} name="trash" style={{color:'#eff9f0'}} />
</TouchableOpacity>
</View>
);
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.

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()}
/>
To iterate and add views dynamically from array, I'm using following code.
export default class CreateFeedPost extends Component {
constructor(props) {
super(props);
this.state = {
selectedImages: ["1", "2", "3"]
};
}
render() {
let animation = {};
let color = Platform.OS === "android"
? styleUtils.androidSpinnerColor
: "gray";
return (
<View style={{ flex: 1, flexDirection: "column" }}>
<View style={styles.topView}>
<View style={styles.closeButtonView}>

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 (...);
})
