I have an array which displays a list of jobs with the radio button(each).If I click any radio button I want to get its value so far I'm getting an error input must be a function received undefined. how can I achieve something like this in react native?
Code
import React, {useState} from 'react';
import {View, Text, TextInput, Image,Button,Body,Pressable,ScrollView,Switch} from 'react-native';
export default function Home({ navigation}){
let roles = navigation.getParam('roles')
const [isEnabled, setIsEnabled] = useState(false);
const toggleSwitch = () => setIsEnabled(previousState => !previousState);
const handleClick = (data, e) => {
alert(e.target.value, data);
}
<View>
{
Object.keys(roles).map((key) => {
return (
<View>
<View style={styles.XYQHC}>
<Text>{roles[key]['name']}</Text>
<Switch
trackColor={{ false: "#767577", true: "#81b0ff" }}
thumbColor={isEnabled ? "#f5dd4b" : "#f4f3f4"}
ios_backgroundColor="#3e3e3e"
onValueChange={toggleSwitch}
value={isEnabled}
/>
<input type="radio" name="roles" value={roles[key]['name']} defaultChecked={roles[key]['id'] == 3 ? true : false } onClick={handleClick.bind(this, roles[key]['name'])}/>
</View>
</View>
)
})
}
</View>
};
I had to edit a little bit to make it work and to assume some input data but here is a working example of your code:
import React, { useState, useEffect } from 'react';
import { View, Text, TouchableOpacity } from 'react-native';
function RadioButton({ label, onPress, selected, style }) {
return (
<TouchableOpacity
style={[
{
flexDirection: 'row',
alignItems: 'center',
marginLeft: 12,
marginVertical: 20,
},
style,
]}
onPress={onPress}>
<View
style={{
height: 24,
width: 24,
borderRadius: 12,
borderWidth: 2,
borderColor: '#000',
alignItems: 'center',
justifyContent: 'center',
marginRight: 12,
}}>
{selected ? (
<View
style={{
height: 12,
width: 12,
borderRadius: 6,
backgroundColor: '#000',
}}
/>
) : null}
</View>
<Text>{label}</Text>
</TouchableOpacity>
);
}
export default function Home({ navigation }) {
// let status = navigation.getParam('status');
let status = 2;
// let roles = navigation.getParam('roles');
let roles = [
{
id: 1,
name: 'lawyer',
},
{
id: 2,
name: 'farmer',
},
{
id: 3,
name: 'architect',
},
];
const [isEnabled, setIsEnabled] = useState(false);
const [chosenRole, setChosenRole] = useState(false);
useEffect(() => {
roles.find((role) => {
if (role.id === status) {
setChosenRole(role);
return true;
}
return false;
});
}, []);
const handleClick = (data) => {
console.log(data);
setChosenRole(data);
};
return (
<View style={{ marginTop: 30 }}>
{roles.map((role) => {
return (
<View>
<RadioButton
label={role.name}
selected={role.name === chosenRole.name}
onPress={() => handleClick(role)}
/>
</View>
);
})}
</View>
);
}

I'm using React Native Expo. Currently i'm trying to make an application which uses a barcodescanner for scanning QR-code objects. I've implemented a turn camera button for the front or back camera but when i press the button it does nothing only when i switch from one screen to the other. I think there is something wrong with refreshing the screen immediately but i've no clue of how i should solve this problem

I am not able to push the number index in the array of useState.
Where I am going wrong, do I want to push the index of numbers when I click them?
I am extracting the previous state array and then I push new but nothing happens.
How to push a new element inside useState array React hook? My code doesn't work!!

you are not calling the function
onClick={() => selectNumber(index)}
You need to change the onClick prop and pass the randomNumber (or index depending of what you want to do) to the selectNumber function:
// Not sure if you want to pass randonNumber or index but you get the idea
onClick={() => selectNumber(randomNumber)}
<TouchableOpacity onPress={handlePress()}>
should be
<TouchableOpacity onPress={()=>handlePress()}>
and
() => selectNumber
should be
() => selectNumber()
please try it

I am trying to make a flip card game. I used GestureFlipView for flip card animation. I want to display these flip card in 3X3 grid and for that I have used from react native. But the problem occurs that cards are not getting flipped and it is showing vague behaviour as well. Just the last card working fine and other cards are doing unpredictable behaviour.

You need to use ref correctly. you can Read about it here
const Cards = (props) => {
//first define ref
const flipViewRef = React.useRef();
//in onPress use it like this
<TouchableOpacity onPress = {() => {
flipViewRef.current.flipRight()
...
}} >
//in GestureFlipView assign it like this
<GestureFlipView ref={flipViewRef} />
}
The primary cause of your troubles is the fact that you are using a this reference within a functional component. As explained here, the value of this will be determined by how the function is called, and might even be undefined. A more reliable approach of using this is from a class context. For React, that means using a class component, rather than a functional component, which is what is being used here. You can read about function and class components here.
Something else to consider is if a FlatList is appropriate here. Typically, this component is used to improve performance for rendering large lists. Instead of using a FlatList, I would recommend using something simpler, such as a set of View components to draw the cards. Here is a complete example based on your code:
import React, { useState } from 'react';
import { View, Dimensions, StyleSheet, Text, TouchableOpacity } from 'react-native';
import GestureFlipView from 'react-native-gesture-flip-card';
const Card = (props: any) => {
const [flipType, setFlip] = useState('left');
let flipView: any;
const onFrontPress = () => {
flipView.flipRight()
setFlip('right');
}
const cardDimensions = { width: 0.9 * props.size, height: 0.9 * props.size };
const renderFront = () => {
return (
<TouchableOpacity onPress={onFrontPress} style={[styles.front, cardDimensions]}>
<Text style={styles.frontText}>Swipe Me</Text>
</TouchableOpacity>
);
};
const renderBack = () => {
return (
<View style={[styles.back, cardDimensions]}>
