How to use react-native-vision-camera instead of expo-camer?

How to use react-native-vision-camera instead of expo-camera? earlier I was developing my project in expo but currently I am developing it using react native cli can anyone can tell me how can I use this package call react-native-vision-camera and make it work same as my expo code with any errors I tried using myself my it was giving me a black screen In my case android
Expo Code:
import { Camera } from 'expo-camera';
import { TouchableOpacity, Text, View, ActivityIndicator } from 'react-native';
import { useState, useEffect, useRef } from "react";
import * as FaceDetector from 'expo-face-detector';
export default function CameraPage({ navigation }) {
const [hasPermission, setHasPermission] = useState(null);
const cameraRef = useRef(null);
const [faceData, setFaceData] = useState([]);
useEffect(() => {
(async () => {
const { status } = await Camera.requestCameraPermissionsAsync();
setHasPermission(status === 'granted');
})();
}, []);
if (hasPermission === null) {
return <View />;
}
if (hasPermission === false) {
return <Text>No access to camera</Text>;
}
const handleTakePicture = async () => {
if (faceData.length === 0) {
alert('No Face')
}
else if
(cameraRef.current) {
const photo = await cameraRef.current.takePictureAsync();
console.log(photo.uri)
if (!photo.cancelled) {
navigation.navigate('addphoto', { Image: photo.uri });
}
}
}
const handleFacesDetected = ({ faces }) => {
setFaceData(faces);
}
return (
<View style={{ flex: 1, backgroundColor: 'black' }}>
<Camera
onFacesDetected={handleFacesDetected}
faceDetectorSettings={{
mode: FaceDetector.FaceDetectorMode.fast,
detectLandmarks: FaceDetector.FaceDetectorLandmarks.none,
runClassifications: FaceDetector.FaceDetectorClassifications.none,
minDetectionInterval: 100,
tracking: true,
}}
style={{
borderTopLeftRadius: 30,
borderTopRightRadius: 30,
borderBottomLeftRadius: 30,
borderBottomRightRadius: 30,
overflow: 'hidden',

}}
type={Camera.Constants.Type.front}
ref={cameraRef}
>
<View style={{ flex: 1, backgroundColor: 'transparent', flexDirection: 'row' }}>
</View>
</Camera>
<TouchableOpacity

}}
onPress={handleTakePicture}
>
<View style={{ opacity: 0.5 }} />
</TouchableOpacity>
</View>
);
}

getByTestId Not Finding TestID

As I mentioned in some of my prior posts, I am new to testing React Native apps. I am trying to test this function that checks if a person is over 21 years old. I am experiment with the React Native testing to see where I should test components, so currently I put them on two elements arbitrarily. However, when I go to get the element by testID, it says that that the testID cannot be found. Below is where I have them currently/initially -- I moved them around to other locations and was yielding the same response. The test scripts are below:
import '../../../matchMedia.mock';
import React from 'react';
import renderer, { act } from 'react-test-renderer';
import VerificationScreen from '../VerificationScreen';
import { RecoilRoot } from 'recoil';
import { render, fireEvent, screen } from '#testing-library/react-native'
import ReactDOM from 'react-dom';
const mockNavigation = {
navigate: jest.fn(),
addListener: jest.fn()
}
test('renders correctly', () => {
const tree = renderer.create(<RecoilRoot><VerificationScreen navigation= {mockNavigation}/></RecoilRoot>).toJSON();
expect(tree).toMatchSnapshot();
});
test('renders default elements', () => {
const { getAllByText } = render(<RecoilRoot><VerificationScreen navigation= {mockNavigation}/></RecoilRoot>);
expect(getAllByText('Can I see some ID?').length).toBe(1);
expect(getAllByText('You must be of legal drinking age to use this app.').length).toBe(1);
expect(getAllByText('Enter Now').length).toBe(1);
});
test('display error if the user is not 21', () => {
const { getAllByText } = render(<RecoilRoot><VerificationScreen navigation= {mockNavigation}/></RecoilRoot>);
console.log(getAllByText('MMDDYYYY'));
fireEvent.changeText(queryByTestId('Verification.DOB'), '10012021');
fireEvent.press(getByTestId('Verification.Submit'));
})
The component itself is below:

You are gettinge rror becaue it cant' find TouchablOpacity. Try to mock it at the top like this-

React native `input` must be a function received undefined

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>
);
}

create variable dynamically in react-native component

i need to create a variable in a react-native component, which i want to use several times...each instance of this component needs to have a different variable name to reference to.
<View ref={view => { shapeView = view; }}
onLayout={({ nativeEvent }) => {
shapeView.measure( (x, y, width, height, pageX, pageY) => {
console.log('- - - DEBUG: width:' + width + ', pageX:'+ pageX + ', pageY:' + pageY);
let shapePickerPosition = {w: width, x: pageX, y: pageY};
setShapeCoords(shapePickerPosition);
})
}}>
as i said, i want to use this code inside a component, and this component several times, and if i don't change die variable: "shapeView" i end up with just the coordinates from the last instance of that component..
here's the whole component:
import React, {useState, useEffect} from 'react';
import {StyleSheet, View, Text, Modal, TouchableOpacity, Pressable, FlatList} from 'react-native';
import { useTheme} from '#react-navigation/native';
// ------------------PickerRow-----------------------------------------------------------------------
function CustomPickerRow(props) {
const { colors } = useTheme(); // works
const theme = useTheme();
const [selectedItem, setSelectedItem] = useState('choose');
const [coordinates, setCoordinates] = useState();
const setItem = (value) => {
// set parent state
props.action(value)
}
return (
<View
ref = { view => { shapeView = view; } }
onLayout={({ nativeEvent }) => {
shapeView.measure( (x, y, width, height, pageX, pageY) => {
console.log('height:', height);
console.log('width:', width);
console.log('x:', pageX);
console.log('y:', pageY);
let coords = {w: width, x: pageX, y: pageY};
setCoordinates(coords);
})
}}
style = {{
flexDirection: 'row',
justifyContent: 'space-between',
alignItems: 'center',
height: 25,
paddingLeft: 5,
marginBottom: 3,
backgroundColor: colors.frameBackground,
borderColor: colors.borderColor,
borderWidth: 1,
borderRadius: 5}}>
<View style = {styles.icon} >
<Text style = {styles.text}>{props.icon}</Text>
</View>
<View style = {styles.description} >
<Text style = {{fontSize: 11, fontWeight: 'bold', color: colors.text, textAlign: 'left', marginLeft: 5,}}>{props.title}</Text>
</View>
<MyPicker data={props.data} action={setItem} position={coordinates}/>
</View>
);
}
// ------------------MyPicker-----------------------------------------------------------------------
function MyPicker(props) {
const { colors } = useTheme(); // works
const theme = useTheme();
const [isVisible, setIsVisible] = useState(false);
const [selectedItem, setSelectedItem] = useState(props.data[0].key)
const [coordinates, setCoordinates] = useState({w: 180, x: 0, y: 0});
useEffect(() => {
if (props.position) {
setCoordinates(props.position);
}
})
const setItem = item => {
// set parent state
props.action(item.value);
setIsVisible(false);
console.log("chosen value = " + item.key);
setSelectedItem(item.key);
}
const showPicker = () => {
setIsVisible(true);
}
const renderItem = ({item}) => {
return <View>
<Pressable onPress={() => setItem(item)}>
<Text style={{color: colors.text, fontSize: 17, alignSelf: 'center', paddingTop: 3}}>
{item.key}
</Text>
</Pressable>
</View>
}
return (
<View style={{flex:5, backgroundColor: 'transparent'}}>
<TouchableOpacity onPress={showPicker}>
<Text style={{color: colors.textSubtitleColor, fontSize: 11, alignSelf: 'flex-end', paddingRight: 10}}>
{selectedItem}
</Text>
</TouchableOpacity>
<Modal animationType="fade"
transparent={true}
visible={isVisible}
style={styles.testPicker}
onRequestClose={() => {
console.log('Modal has been closed.');
}}
>
<View style={{ backgroundColor: colors.frameBackground,
borderColor: colors.borderColor,
borderWidth: 1,
borderRadius: 5,
position: 'absolute',
width: 180,
height: 200,
left: coordinates.x, //100,
top: coordinates.y //160
}}>
<FlatList
data={props.data}
renderItem={renderItem}
/>
</View>
</Modal>
</View>
);
}
const styles = StyleSheet.create({
testPicker: {
backgroundColor: 'gray',
position: 'absolute',
width: 112,
height: 200,
left: 100,
top: 160
},
icon: {
flex: 1,
backgroundColor: '#00529F',
marginRight: 0,
borderRadius: 5
},
description: {
flex: 2,
height: 17,
backgroundColor: 'transparent',
marginRight: 0,
borderRadius: 5
},
});
export default CustomPickerRow;
and i call that component like this:
<CustomPickerRow id='shapePicker' icon='2' title='Shape:' data={shapeItems} action={setShape} selectedItem={selectedShape} visible={modalVisible} />```

shapeView should be a ref like this:
const MyComponent = () => {
const shapeView = useRef();
return (
<View
ref={view => shapeView.current = view}
/* could also look like this: ref={shapeView} */
onLayout={({nativeEvent}) => {
shapeView.current.measure(...);
}
/>
)
}
It SHOULD NOT be like this:
let shapeView; // this is outside your component - it shouldn't be here
const MyComponent = () => {
return (
<View
ref={view => shapeView = view}
onLayout={({nativeEvent}) => {
shapeView.measure(...);
}
/>
)
}
In a class based component it could look like this:
class MyComponent extends React.Component {
constructor() {
this.shapeView = React.createRef();
}
render() {
return (
<View
ref={this.shapeView}
onLayout={({nativeEvent}) => {
this.shapeView.current.measure(...);
}
/>
)
}
}

React Native: Touchable Opacity element is clickable on iOS but not Android

I'm working on a React Native app with a typeahead component. The typeahead displays options that overlay other content on the route (see right image below). When a user clicks one of those options, an onPress listener runs a function:
This all works just fine on iOS. On Android though, the onPress event is never received. Even more strangely, when I try to click on an option lower in the list (like Boston, MA, USA), the onPress event is received by the card below the pressed option (Djerba).
Does anyone know what might cause this behavior? I'd be super grateful for any insights others can offer on this query.
Here's the code for the Explore view and the typeahead components.

Try to move Typeahead component below all CardRow components and set position:absolute for Typeahead. Probably on android - the latest view shadow all views before (I am not sure, but I think you have to try it for next discovering issue).
You should also remove position: absolute from all but one component. Working code:
