I'm having an issue when using redux form with react native, when I toggle the password visibility the password field input is cleared, when I remove redux form things work as expected. Below is the code I'm using, I also tried saving the value to a local state but that doesn't work either.
import React, {useState} from 'react';
import {StatusBar} from 'react-native';
import {Icon, FormControl, Button, HStack, Pressable} from 'native-base';
import {Field, reduxForm} from 'redux-form';
import MaterialIcons from 'react-native-vector-icons/MaterialIcons';
import PropTypes from 'prop-types';
import Input from './Input';
import {withActions} from 'context/ActionsContext';
const LoginForm = props => {
const {handleSubmit, submitting, invalid, toggleCreate, toggleModal} = props;
const [show, setShow] = useState(false);
return (
<>
<StatusBar barStyle="light-content" />
<Field
name="email"
component={field => (
<FormControl isInvalid={field.meta.error} mb="6">
<Input
input={field.input}
key={field.name}
placeholder="Email Address"
type="text"
keyboardType="email-address"
textContentType="emailAddress"
light
/>
<FormControl.ErrorMessage>
{field.meta.error}
</FormControl.ErrorMessage>
</FormControl>
)}
/>
<Field
name="password"
component={field => (
<FormControl isInvalid={field.meta.error} mb="6">
<Input
input={field.input}
key={field.name}
placeholder="Password"
type={show ? 'text' : 'password'}
keyboardType="default"
textContentType="password"
light
rightComponent={
<Pressable onPress={() => setShow(!show)}>
<Icon
as={
<MaterialIcons
name={show ? 'visibility' : 'visibility-off'}
/>
}
size={5}
mr="2"
/>
</Pressable>
}
/>
<FormControl.ErrorMessage>
{field.meta.error}
</FormControl.ErrorMessage>
</FormControl>
)}
/>
<Button
rounded="lg"
mt="3"
colorScheme="red"
_text={{
fontFamily: 'neuzeitBook',
fontSize: 'md',
fontWeight: '700',
}}
isDisabled={submitting || invalid}
onPress={handleSubmit}>
Sign in
</Button>
<Button
rounded="lg"
mt="6"
variant="solidLight"
_text={{
fontFamily: 'neuzeitBook',
fontSize: 'md',
}}
onPress={toggleCreate}>
Create Account
</Button>
<HStack mt="6" justifyContent="center">
<Button
p="3"
color="white"
variant="link"
onPress={toggleModal}
_text={{
fontFamily: 'neuzeitBook',
fontSize: 'md',
fontWeight: 'bold',
color: 'white',
}}>
Reset Password
</Button>
</HStack>
</>
);
};
LoginForm.propTypes = {
handleSubmit: PropTypes.func.isRequired,
placeholder: PropTypes.string,
};
export default reduxForm({
form: 'login',
})(withActions(LoginForm));
I tried removing redux form and it works as expected.

Have implemented a screen that uses checkboxes.
Following the example from React Native Checkbox
On clicking a checkbox, receive the following error:
TypeError: _this.setState is not a function. (In '_this.setState({
checked: !_this.state.checked
})', '_this.setState' is undefined)
Below is my code:
import * as React from 'react';
import {Dimensions, StyleSheet, View} from 'react-native';
import {Button, Card, CheckBox} from 'react-native-elements';
function MyScreen({navigation}) {
return (
<View style={styles.view}>
<View style={styles.panel}>
<Card containerStyle={styles.card} title="My Checkboxes">
<CheckBox
title="My Checkbox"
checked={this.state.checked}
onPress={() => this.setState({checked: !this.state.checked})}
/>
</Card>
<Button
style={styles.button}
title="Done"
onPress={() => navigation.navigate('Home')}
/>
</View>
</View>
);
}
const styles = StyleSheet.create({
view: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
},
panel: {
width: Dimensions.get('window').width,
justifyContent: 'center',
alignItems: 'center',
position: 'absolute',
top: 0,
},
button: {
margin: 5,
width: 150,
height: 50,
},
card: {
width: Dimensions.get('window').width,
marginBottom: 20,
},
});
export default MyScreen;
I've tried searching here, and pretty much everywhere, and can't seem to find a solution.
Any assistance would be appreciated.
You are using a functional component.
Change it to a class component or use hooks inside this functional component.
Change your code as following
class component
import React, { Component } from 'react'
import {Dimensions, StyleSheet, View} from 'react-native';
import {Button, Card, CheckBox} from 'react-native-elements';
export default class App extends Component {
state={ checked: false };
render() {
return (
<View style={styles.view}>
<View style={styles.panel}>
<Card containerStyle={styles.card} title="My Checkboxes">
<CheckBox
title="My Checkbox"
checked={this.state.checked}
onPress={() => this.setState({checked: !this.state.checked})}
/>
</Card>
<Button
style={styles.button}
title="Done"
onPress={() => navigation.navigate('Home')}
/>
</View>
</View>
)
}
}
or functional component
import React, {useState} from 'react';
import {Dimensions, StyleSheet, View} from 'react-native';
import {Button, Card, CheckBox} from 'react-native-elements';
function MyScreen({navigation}) {
const [checked, toggleChecked] = useState(false);
return (
<View style={styles.view}>
<View style={styles.panel}>
<Card containerStyle={styles.card} title="My Checkboxes">
<CheckBox
title="My Checkbox"
checked={checked}
onPress={() => toggleChecked(!checked)}
/>
</Card>
<Button
style={styles.button}
title="Done"
onPress={() => navigation.navigate('Home')}
/>
</View>
</View>
);
}
If you are using your functional component as a child in another component, you can have use props instead.
function MyScreen({navigation, onChecked, checked}) {
return (
<View style={styles.view}>
<View style={styles.panel}>
<Card containerStyle={styles.card} title="My Checkboxes">
<CheckBox
title="My Checkbox"
checked={checked}
onPress={onChecked}
/>
</Card>
<Button
style={styles.button}
title="Done"
onPress={() => navigation.navigate('Home')}
/>
</View>
</View>
);
}
MyScreen.propTypes = {
checked: PropTypes.bool.isRequired,
onChecked: PropTypes.func.isRequired
};
export default MyScreen;
On the parent component the onChecked can look like:
onChecked =()=>{
...
this.setState({checked: !this.state.checked})
}
Also in the parent component, you can use MyScreen as:
<MyScreen
onCheck={this.onChecked}
checked={this.state.checked}
/>
I'm new to React Native and learning from a course. Unfortunately, I'm stuck in a problem where my picker doesn't show up. Even after styling my CardSection, it is not working. Here is a the code. Please help
I've tried styling the CardSection but it doesn't seem to be working
import React, { Component } from 'react';
import { Picker, Text } from 'react-native';
import { connect } from 'react-redux';
import { employeeUpdate } from '../actions';
import { Card, CardSection, Input, Button } from './common';
class EmployeeCreate extends Component {
render() {
return (
<Card>
<CardSection>
<Input
label='Name'
placeholder='Jane'
value={this.props.name}
onChangeText={value => this.props.employeeUpdate({ prop: 'name', value })}
/>
</CardSection>
<CardSection>
<Input
label='Phone'
placeholder='555-555-5555'
value={this.props.phone}
onChangeText={value => this.props.employeeUpdate({ prop: 'phone', value })}
/>
</CardSection>
<CardSection style={{ flexDirection: 'column' }}>
<Text style={styles.pickerTextStyle}>Shift</Text>
<Picker
style={{ flex: 1 }}
selectedValue={this.props.shift}
onValueChange={value => this.props.employeeUpdate({ prop: 'shift', value })}
>
<Picker.Item label="Monday" value="Monday" />
<Picker.Item label="Tuesday" value="Tuesday" />
<Picker.Item label="Wednesday" value="Wednesday" />
<Picker.Item label="Thursday" value="Thursday" />
<Picker.Item label="Friday" value="Friday" />
<Picker.Item label="Saturday" value="Saturday" />
<Picker.Item label="Sunday" value="Sunday" />
</Picker>
</CardSection>
<CardSection>
<Button>Create</Button>
</CardSection>
</Card>
);
}
}
const styles = {
pickerTextStyle: {
fontSize: 18,
paddingLeft: 20
}
};
const mapStateToProps = (state) => {
const { name, phone, shift } = state.employeeForm;
return { name, phone, shift };
};
export default connect(mapStateToProps, { employeeUpdate })(EmployeeCreate);
Here is the CardSection
import React from 'react';
import { View } from 'react-native';
const CardSection = (props) => {
return (
<View style={[styles.constainerStyle, props.style]}>
{props.children}
</View>
);
};
const styles = {
constainerStyle: {
bottomBorderWidth: 1,
padding: 5,
backgroundColor: '#FFF',
justifyContent: 'flex-start',
flexDirection: 'row',
borderColor: '#DDD',
position: 'relative'
}
};
export { CardSection };
I expect the CardSection to show up like a Picker
Found the solution. Adding the following styling to the picker resolves it
style={{ alignItems: "center" }}

I am new to react-native,I am trying to create a simple page using all input components from react-native elements 1.00 beta4.My problem is I failed to align checkbox near my text component even if the parent view flexdirection is in 'row'.
register.js
import React,{ Component } from 'react';
import { Field,reduxForm } from 'redux-form';
import { View,Button } from 'react-native';
import {Icon,CheckBox,Text,Input} from 'react-native-elements';
const renderField=({label,keyboardType,name,icon,iconType}) => {
return(
<View style={{flexDirection:'row'}}>
<Input placeholder={label} inputContainerStyle={{borderWidth:2,borderColor:'lightgrey',borderRadius:20}} inputStyle={{color:'grey'}} leftIcon={<Icon size={25} type={iconType} name={icon} color="grey" />} errorStyle={{fontSize:15}} errorMessage="error" />
</View>
)
}
const checkBoxField=({label,keyboardType,name}) => {
return(
<View style={{flexDirection:'row'}}>
<Text>{label}</Text>
<CheckBox title='Male' checkedIcon='dot-circle-o' uncheckedIcon='circle-o' checked={true} containerStyle={{backgroundColor:'transparent'}} />
</View>
)
}
const RegisterForm=props => {
const {handleSubmit}=props;
return(
<View style={{flex:1,flexDirection:'column',margin:20,justifyContent:'flex-start',alignItems:'center'}}>
<Field label="Username" component={renderField} name="username" icon="user" iconType="font-awesome" />
<Field label="Email" component={renderField} name="username" icon="email" iconType="zocial" />
<Field label="Gender" component={checkBoxField} name="gender" />
<Button title='SUBMIT' onPress={handleSubmit} />
</View>
)
}
const Register=reduxForm({
form:'register',
})(RegisterForm);
export default Register;
output
what is the problem here?How can I align my checkbox (using flexbox algorithm)
you can use flex property like justifyContent and alginItem or you can also use Text property like alignText, and alignSelf.
const checkBoxField=({label,keyboardType,name}) => {
return(
<View style={{flexDirection:'row',alignItems:'center',justifyContent:'center'}}>
<Text style={{alignSelf:'center',textAlign:'center'}}>{label}</Text>
<CheckBox title='Male' checkedIcon='dot-circle-o' uncheckedIcon='circle-o' checked={true} containerStyle={{backgroundColor:'transparent'}} />
</View>
)
}
My code is here
I am getting the error below.
I believe its something to do with the employee create line in the code below and i cannot figure out why this might be happening. I am doing this from a tutorial
import React, { Component } from 'react';
//import { View, Text } from 'react-native';
import { connect } from 'react-redux';
import { Picker, Text } from 'react-native';
import { employeeUpdate, employeeCreate } from '../actions';
import { Card, CardSection, Input, Button } from './common';
class EmployeeCreate extends Component {
onButtonPress() {
const { name, phone, shift } = this.props;
this.props.employeeCreate({ name, phone, shift: shift || 'Monday' });
}
render() {
return (
//
// <View>
// <Text>Employees</Text>
// </View>
<Card>
<CardSection>
<Input
label="Name"
placeholder="Jane"
value={this.props.name}
onChangeText={value => this.props.employeeUpdate({ prop: 'name', value })}
/>
</CardSection>
<CardSection>
<Input

</Card>
);
}
}
const styles = {
pickerLabelStyle: {
fontSize: 18,

}
};
const mapStateToProps = (state) => {
const { name, phone, shift } = state.employeeForm;
return { name, phone, shift };
};
export default connect(mapStateToProps, {

})(EmployeeCreate);
Here is the error:
Folks- this is resolved. I found my answer.
In the
https://github.com/samrao2/manager-4/blob/master/src/actions/index.js
file. I was not exporting all the actions from the Employeeactions file and so was not exporting the employeeCreate action. i should have put a * there.
Issue is resolved! Thanks!
