I think I've missed a step somewhere and I can't tell how to affect the form field widths to enable them to fill the area horizontally.
import * as React from 'react';
import {
Edit,
SimpleForm,
TextInput,
ReferenceInput,
SelectInput,
ArrayInput,
SimpleFormIterator,
} from 'react-admin';
import {RichTextInput} from 'ra-input-rich-text';
export const ProductNotesEdit = () => (
<Edit>
<SimpleForm>
<ReferenceInput source="productId" reference="products" label="Product">
<SelectInput optionText="name" />
</ReferenceInput>
<TextInput source="productId" />
<ReferenceInput source="promptId" reference="ml_prompts" label="Prompt">
<SelectInput optionText="slug" />
</ReferenceInput>
<TextInput source="promptId" />
<ArrayInput source="contextUrls">
<SimpleFormIterator>
<TextInput source="url" />
</SimpleFormIterator>
</ArrayInput>
<ArrayInput source="contextTexts">
<SimpleFormIterator>
<TextInput source="text" />
</SimpleFormIterator>
</ArrayInput>
<TextInput source="notes" multiline={true} />
</SimpleForm>
</Edit>
);
How can I increase the width of the fields?

So it seems that I'm missing the fullwidth argument in my fields.
<TextInput source="notes" multiline fullWidth />

I'm trying to use an AppBar from React Native Material. The icon i use in the IconButton is from react-native-vector-icon. I have no idea why I'm getting error saying Element type is invalid: expect a string. Check the render method for IconButton as I literally copied the exact code from the React Native Material official doc.
import {AppBar, IconButton} from '#react-native-material/core';
import {Icon} from 'react-native-vector-icons/Entypo';
<AppBar
title="Title"
leading={props => (
<IconButton
icon={props => <Icon name="menu" {...props} />}
{...props}
/>
)}
/>
==> Try My Code it works.
import {AppBar, IconButton} from '#react-native-material/core';
import Icon from 'react-native-vector-icons/Entypo';
<AppBar
title="Title"
leading={props => (
<IconButton
icon={props => <Icon name="menu" {...props} />}
{...props}
/>
)}
/>
I'm using react-native-paper TextInput to show email icon on the left side of text input and that icon should be green (#22C55E) but it's still showing the default color.
<TextInput
placeholder={t('Email')}
style={styles.textInput}
mode="outlined"
outlineColor={Colors.transparent}
activeOutlineColor={Colors.hostessGreen}
theme={{ roundness: 16 }}
left={
<TextInput.Icon
icon={'email-outline'}
color="#22C55E"
style={styles.leftIcon as StyleProp<ViewStyle>}
size={responsiveFontSize(3)}
/>
}
/>
You have to add iconColor='#22C55E' add in place of color="#22C55E" props in TextInput.Icon.you will be able to change color easily.
<TextInput
placeholder={t('Email')}
style={styles.textInput}
mode="outlined"
outlineColor={Colors.transparent}
activeOutlineColor={Colors.hostessGreen}
theme={{ roundness: 16 }}
left={
<TextInput.Icon
icon={'email-outline'}
iconColor="#22C55E"
style={styles.leftIcon as StyleProp<ViewStyle>}
size={responsiveFontSize(3)}
/>
}
/>
I'm using react-native-community/picker v1.6.1, and I'm trying to make a pre-styled picker item to avoid having the color property on each item. Below is a showcase App.js. The red picker works as expected but the yellow one renders in black instead of yellow and I don't understand why. The code is tested in an iOS emulator with a freshly generated React Native app version 0.62.2 where I've installed the picker component.
import React, {useState} from 'react';
import {SafeAreaView} from 'react-native';
import {Picker} from '#react-native-community/picker';
const YellowPickerItem = props => {
return <Picker.Item {...props} color={'yellow'} />;
};
const App = () => {
const [redValue, setRedValue] = useState(2);
const [yellowValue, setYellowValue] = useState(3);
return (
<>
<SafeAreaView style={{flex: 1}} backgroundColor={'gray'}>
<Picker selectedValue={redValue} onValueChange={setRedValue}>
<Picker.Item label={'Red 1'} value={1} key={1} color={'red'} />
<Picker.Item label={'Red 2'} value={2} key={2} color={'red'} />
<Picker.Item label={'Red 3'} value={3} key={3} color={'red'} />
<Picker.Item label={'Red 4'} value={4} key={4} color={'red'} />
</Picker>
<Picker selectedValue={yellowValue} onValueChange={setYellowValue}>
<YellowPickerItem label={'Yellow 1'} value={1} key={1} />
<YellowPickerItem label={'Yellow 2'} value={2} key={2} />
<YellowPickerItem label={'Yellow 3'} value={3} key={3} />
<YellowPickerItem label={'Yellow 4'} value={4} key={4} />
</Picker>
</SafeAreaView>
</>
);
};
export default App;
The strangest thing is that the code runs just as well if I change the YellowPickerItem component to:
const YellowPickerItem = props => {
return <SafeAreaView />;
};
It feels like I'm missing something basic about react components here, so grateful for a nudge in the right direction.

You can use itemStyle prop of the picker to styling your picker item.
I'm trying to use redux-form, but, as I read, I need HOC for Input field to replace onTextChange to onChange. I have:
import React from 'react';
import {Input} from 'native-base';
export default function InputField(props) {
const { input, ...inputProps } = props;
return (
<Input
{...inputProps}
onChangeText={input.onChange}
onBlur={input.onBlur}
onFocus={input.onFocus}
value={input.value}
/>
);
};
and use it in my form:
<Item style={{marginTop: 10, width: "100%"}}>
<Field name="login" component={(props) => {
return (
<InputField {...props} keyboardType="email-address" placeholder='E-mail' />
)
}}/>
</Item>
But every time I type key, the field loses focus. Some "experts" recommend use focus() function. But what if I edit text in the middle of it?
Any solutions? Or maybe native-base have compatible textfield component?
It is strange, but it works ))
function InputFieldEmail(props) {
return <InputField {...props} keyboardType="email-address" placeholder='E-mail' />;
}
and use it instead arrow functions
<Field name="login" component={InputFieldEmail}/>
I think it's strange )
You must provide the InputField component as a prop so that its value is constant or put it outside the Item component, when it is inside another, every time the state of the upper level is updated, the lower level is forced to return. to start.
If your Input is inside an Item you are probably using a FlatList and your goal is to put it in the header.
You can try something like this:
<View style={{marginTop: 10, width: "100%"}}>
<Field name="login" component={(props) => {
return (
<InputField {...props} keyboardType="email-address" placeholder='E-mail' />
)
}}/>
</View>
<FlatList
ListHeaderComponent={() => {
<Item>
</Item>
}}
/>
Remember to put the styles that were in Item in View.
I am using react elements components in my react-native application.
import React,{ Component } from 'react';
import { Field,reduxForm } from 'redux-form';
import { Text,Input } from 'react-native-elements';
import { View,Button } from 'react-native';
import {Icon,CheckBox} from 'react-native-elements';
const renderField=({label,keyboardType,name,icon,iconType,input:{onChange,...restInput}}) => {
return(
<View style={{flexDirection:'row'}}>
<Input onChangeText={onChange} {...restInput} keyboardType={keyboardType} 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}) => {
var val=true;
return(
<View >
<View style={{flexDirection:'row',alignItems:'center',justifyContent:'center'}}>
<Text style={{fontSize:18}}>{label}</Text>
<CheckBox title='Male' checkedIcon='dot-circle-o' uncheckedIcon='circle-o' containerStyle={{backgroundColor:'transparent',borderWidth:0,padding:0}} textStyle={{fontSize:18}} />
<CheckBox title='Female' checkedIcon='dot-circle-o' uncheckedIcon='circle-o' containerStyle={{backgroundColor:'transparent',borderWidth:0,padding:0}} textStyle={{fontSize:18}} />
</View>
<View><Text style={{fontSize:15,color:'red'}}>error</Text></View>
</View>
)
}
const submit = values => {
console.log('submitting form', values)
}
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="email" icon="email" iconType="zocial" />
<Field label="Gender" component={checkBoxField} name="gender" />
<Button title='SUBMIT' onPress={handleSubmit(submit)} />
</View>
)
}
const Register=reduxForm({
form:'register',
})(RegisterForm);
export default Register;
in the above code I am using redux form in my react-native application,by passing onChange() I can retrieve values of text input,but how can I retrieve the values of a radio button?currently the form contains text input values only,I need to add radio button values also. If the user select one value in the radio button I need to unselect other radio button how it will be possible?
You can use react-native-radio-input.
Its very simple to use.
import RadioGroup,{Radio} from "react-native-radio-input";
.
.
.
//Receive the checked value (ES6 syntax)
getChecked = (value) => {
// value = our checked value
alert(value)
}
<RadioGroup getChecked={this.getChecked}>
<Radio iconName={"lens"} label={"The first option"} value={"A"} />
<Radio iconName={"lens"} label={"The first option"} value={"B"} />
<Radio iconName={"lens"} label={"I need numbers"} value={1} />
<Radio label={"Is IconName Optional?"} value={"Yes"} />
<Radio label={"Show Sentence Value"} value={"This is a Sentence"} />
</RadioGroup>
