i want to change value of textInput but it change all value of textinput , i know because of the state, but what the right way to handle this textInput or what i use is numericInput from react-native-numeric-input, thanks for helping.
<ScrollView>
{this.state.display.map((info)=>{
return
<View style={{paddingBottom:5,alignSelf:'center'}} key={info.id}>
<View style={{ ... }}>
<View style={{flexDirection:'row'}}>
...
<View style={{justifyContent:'center',marginLeft:'auto',marginRight:10}}>
<NumericInput
totalWidth={70}
totalHeight={30}
iconSize={10}
initValue={this.state.v6}
value={this.state.v6}
onChange={(v6) => this.setState({ v6 })}
rounded
textColor='#59656F'
iconStyle={{ color: 'white' }}
rightButtonBackgroundColor='#AC9FBB'
leftButtonBackgroundColor='#DDBDD5'
/>
</View>
</View>
</View>
</View>
})}
</ScrollView>
and this my state code
state={
v6:0
}
Try changing the onChange to this:
onChange={(value) => this.setState({ v6: value })}

I'm trying to wrap my flat list and trying to show an Icon after last index of Flatlist. I had tried but it works fine on a single row. when we data goes to next row it would not work.
Here is my flat list code. Modal and Input both are my custom component.
const renderItem = ({item}) => {
return (
<TouchableOpacity style={[styles.tagPostContainer, styles.viewTagContainer]}>
<AppText
type={'input'}
label={`#${item}`}
color={colors.placeholder}
containerStyle={[styles.tagPostInactiveTxt, styles.BgAddedTag]}
/>
</TouchableOpacity>
);
};
return(
<>
<View style={{flexDirection:'row',justifyContent:'flex-start'}}>
<FlatList
data={tags}
renderItem={renderItem}
keyExtractor={keyExtractor}
contentContainerStyle={styles.TagFlatlist}
/>
<TouchableOpacity
style={styles.plusIconContainer}
onPress={() => setVisible(true)}>
<CreateBuildIconFocus height={13} width={13} />
</TouchableOpacity>
</View>
<Modal
visible={visible}
buttonLabel={'Done'}
containerWidth={width / 1.7}
onCancel={onCancel}
onSubmit={onClick}
containerHeight={Platform.OS === 'android' ? 200 : 200}>
<Input
placeholder={'Add Tags'}
autoFocus={true}
minWidth={120}
maxWidth={150}
value={tag}
onChangeText={text => setTag(text)}
/>
</Modal>
</>
)
FlatList styles:
TagFlatlist: {
flexDirection: 'row',
flexWrap: 'wrap',
alignItems: 'center',
},
Here is my design screen.
I find a solution for this. You can implement ListFooterComponent that used for showing something on end of flatlist. Here you can see more details of ListFooterComponent.
Here are the code of Flatlist.
return(
<FlatList
data={tags}
renderItem={renderItem}
keyExtractor={keyExtractor}
ListFooterComponent={
<TouchableOpacity
style={styles.plusIconContainer}
onPress={() => setVisible(true)}>
<CreateBuildIconFocus height={13} width={13} />
</TouchableOpacity>
}
contentContainerStyle={styles.TagFlatlist}
/>

I have a notes input that is multilined. Currently when I press return it goes to the next line and when I tap on a part of the screen that isn't a keyboard nothing happens. So it's just stuck right now and i have to reload the app. I have tried the keyboard dismissal and it still isn't working. This is a child component so maybe that is the issue?
My code:
render() {
return (
<TouchableWithoutFeedback onPress={Keyboard.dismiss()}> //also tried () => Keyboard.dismiss()
<Modal transparent animationType='fade' visible={this.props.createHomeworkModalVisible}>
<View style={styles.containerStyle}>
<View style={styles.modalContainer}>
<Formik
initialValues={{
assignmentName: '',
dueDate: null,
notes: '',
pictures: []
}}
validationSchema={validationSchema}
onSubmit={(values) => {
console.log(values);
}}
>
{formikProps => (
<View>
<View style={{ padding: 5 }}>
<TextInput
placeholder={'Add notes'}
placeholderTextColor='#cdd2c9'
value={formikProps.values.notes}
multiline
style={styles.notesInput}
onChangeText={formikProps.handleChange('notes')}
onBlur={formikProps.handleBlur('notes')}
/>
</View>
</View>
)}
</Formik>
</View>
</View>
</Modal>
</TouchableWithoutFeedback>
);
}
}
You can try something like,
import {Keyboard} from 'react-native'
<TouchableWithoutFeedback onPress={Keyboard.dismiss} accessible={false}>
<View>
<View style={{ padding: 5 }}>
<TextInput
placeholder={'Add notes'}
placeholderTextColor='#cdd2c9'
value={formikProps.values.notes}
multiline
style={styles.notesInput}
onChangeText={formikProps.handleChange('notes')}
onBlur={formikProps.handleBlur('notes')}
/>
</View>
</View>
</TouchableWithoutFeedback>
hope it helps. feel free for doubts
import Keyboard from 'react-native'
Call this function : Keyboard.dismiss()
I have this below code, The alert shows following message:
{"item":{"isPositive":"false", "balance":"-500","currency":"AUD"}}
If I do alert on "ob" I get undefined. My problem is that the Text doesn't display anything:
_renderItemView(item) {
const ob = item
//alert(JSON.stringify(ob))
alert(JSON.stringify(item))
return(<>
<View style={styles.rowContainer}>
<View style={styles.iconContainer}></View>
<View style={styles.descriptionContainer}>
<Text style={styles.subText}>{item.date}asasas</Text>
{/* <Text style={styles.transactionDescText}>{item.description}</Text>
<Text style={styles.subText}>{item.descFrom}</Text> */}
</View>
<View style={styles.balanceContainer}>
{/* <Text style={styles.balance}>{item.currency}</Text>
<Text style={styles.balanceSubText}>{item.balance}</Text> */}
</View>
</View>
</>)
}
I was using renderItem={(item, index) => _renderItemView(item) to render
I needed an extra brace like this
renderItem={({item, index}) =>
I am trying to implement the modal component in this app and for some reasons, I cant make it work. I have done it in another app and even though everything looks as it should in this one, it still doesn't work, it just doesn't toggle!
Here is my code (i call toogleModal() here ):
<TouchableOpacity
activeOpacity={1}
style={styles.slideInnerContainer}
//onPress={() => { alert(`You've clicked '${rest_name}'`); }}
onPress={() => this.toggleModal(rest_name)}
>
<View style={styles.shadow} />
<View style={[styles.imageContainer, even ? styles.imageContainerEven : {}]}>
{this.image}
<View style={[styles.radiusMask, even ? styles.radiusMaskEven : {}]} />
</View>
<View style={[styles.textContainer, even ? styles.textContainerEven : {}]}>
<View style={{ flexDirection: 'row' }}>
{uppercaseTitle}
{ratings}
</View>
<Text
style={[styles.subtitle, even ? styles.subtitleEven : {}]}
numberOfLines={2}
>
{rest_location}
</Text>
</View>
</TouchableOpacity>
Now here is the toggleModal() which should set the state and then call the onPressItem() :
toggleModal = (item) => {
this.setState({ isModalVisible: !this.state.isModalVisible });
this.onPressItem(item);
};
and onPressItem() :
onPressItem = (item) => {
return (
<ThemeProvider theme={theme}>
<Modal animationIn="rubberBand" animationOut={"bounceOut"}
isVisible={this.state.isModalVisible}
onBackdropPress={() => this.setState({ isModalVisible: false })}
>
<View style={{ flex: 1 }}>
{item}
</View>
<View style={{ flex: 1 }}>
<Button title="Hide modal" onPress={this.toggleModal} />
</View>
</Modal>
</ThemeProvider>
)
};
Now, remember this code is taken from another app where modal is working perfectly!
Most probably your issue with click option is connected with incorrect import TouchableOpacity from correct module. Check if you are importing from react-native:
import { TouchableOpacity } from 'react-native';
change this line
onPress={() => this.toggleModal(rest_name)}
to this:
onPress={() => {this.toggleModal(rest_name)}}
you only need to put the function call in brackets
I know there are already so many queries on this topic, I have tried every step but still won't be able to fix the issue.
Here is the code :
render() {
const {sContainer, sSearchBar} = styles;
if (this.props.InviteState.objectForDeleteList){
this.updateList(this.props.InviteState.objectForDeleteList);
}
return (
<View style={styles.mainContainer}>
<CustomNavBar
onBackPress={() => this.props.navigation.goBack()}
/>
<View
style={sContainer}
>
<ScrollView keyboardShouldPersistTaps="always">
<TextInput
underlineColorAndroid={'transparent'}
placeholder={'Search'}
placeholderTextColor={'white'}
selectionColor={Color.colorPrimaryDark}
style={sSearchBar}
onChangeText={(searchTerm) => this.setState({searchTerm})}
/>
</ScrollView>
{this.renderInviteUserList()}
</View>
</View>
);
}
renderInviteUserList() {
if (this.props.InviteState.inviteUsers.length > 0) {
return (
<SearchableFlatlist
searchProperty={'fullName'}
searchTerm={this.state.searchTerm}
data={this.props.InviteState.inviteUsers}
containerStyle={styles.listStyle}
renderItem={({item}) => this.renderItem(item)}
keyExtractor={(item) => item.id}
/>
);
}
return (
<View style={styles.emptyListContainer}>
<Text style={styles.noUserFoundText}>
{this.props.InviteState.noInviteUserFound}
</Text>
</View>
);
}
renderItem(item) {
return (
this.state.userData && this.state.userData.id !== item.id
?
<TouchableOpacity
style={styles.itemContainer}
onPress={() => this.onSelectUser(item)}>
<View style={styles.itemSubContainer}>
<Avatar
medium
rounded
source={
item.imageUrl === ''
? require('../../assets/user_image.png')
: {uri: item.imageUrl}
}
onPress={() => console.log('Works!')}
activeOpacity={0.7}
/>
<View style={styles.userNameContainer}>
<Text style={styles.userNameText} numberOfLines={1}>
{item.fullName}
</Text>
</View>
<CustomButton
style={{
flexWrap: 'wrap',
alignSelf: 'flex-end',
marginTop: 10,
marginBottom: 10,
width: 90,
}}
showIcon={false}
btnText={'Add'}
onPress={() => this.onClickSendInvitation(item)}
/>
</View>
</TouchableOpacity> : null
);
}
**I even tried with bellow code as suggested by #Nirmalsinh **:
<ScrollView keyboardShouldPersistTaps="always" style={sContainer}>
<CustomNavBar
onBackPress={() => this.props.navigation.goBack()}
/>
<TextInput underlineColorAndroid={'transparent'}
placeholder={'Search'}
placeholderTextColor={'white'}
selectionColor={Color.colorPrimaryDark}
style={sSearchBar}
onChangeText={(searchTerm) => this.setState({searchTerm})} />
{this.renderInviteUserList()}
</ScrollView>
I have followed this article:
https://medium.com/react-native-training/todays-react-native-tip-keyboard-issues-in-scrollview-8cfbeb92995b
I have tried with keyboardShouldPersistTaps=handled also but still, I have to tap twice on my Custom Button to perform an action. Can anybody tell me what I am doing wrong inside the code?
Thanks.
You need to add give value always in keyboardShouldPersistTaps to allow user tap without closing the keyboard.
keyboardShouldPersistTaps='always'
For example:
<ScrollView keyboardShouldPersistTaps='always'>
// Put your component
</ScrollView>
NOTE: Kindly put your tappable component inside the ScrollView. Otherwise it won't work.
You can use keyboardShouldPersistTaps='handled' in a ScrollView or Scrollables like FlatList SectionList etc. and embed a TouchableWithoutFeedBack to handle the case for dismiss on outside clicks.
<TouchableWithoutFeedback onPress={Keyboard.dismiss}>
<ScrollView keyboardShouldPersistTaps='handled'>
// Rest of the content.
</ScrollView/>
</TouchableWithoutFeedback>
For FlatList and SectionList you will have to handle KeyBoard.dismiss separately.
Please try this, It's working for me, it will works you also, i hope it helps...
