I am currently making a mobile app and part of it is collecting user data. At the minute I am stuck on getting the DatePicker to show on screen once the text field has been clicked on. I have tried to use the onFocus prop but it does not seem to be working and its not throwing any errors in the console. Here is the code that i have tried using:
const showDatePicker = () => {
return(
<DateTimePicker
value={date}
mode='date'
is24Hour={true}
display="spinner"
onChange={onChange}
/>
)
}
<View style={styles.inputContainer}>
<FontAwesome name="user-circle-o" color={'#808080'} size={20}/>
<TextInput onFocus={() => showDatePicker()} style={styles.input} placeholder="Date Of Birth"
/>
</View>
To give some additional context to the problem I am using a modal which acts as a form for collecting the data. Any help or tips appreciated.
You can wrap the TextInput with a <Pressable />.
<Pressable onPress={() => showDatePicker()}>
<TextInput />
</Pressable>

I am making an android app with ReactNative. When a button is clicked, an alert shows up with the result (My code is Alert.alert(''Results:", returnResults(a,b,c)). Is there a way I can use Modal and the function returnResults(a,b,c) with it to show the message in a more customised way?
The problem is that when I use normal alert, the text is different on every device and I want to prevent that.(I want to specify the font, its size etc)
const Modal = () => {
const [modal, setModal] = useState(false);
return (
<View>
<Button title="Open Modal" onPress={() => setModal(true)} />
<Modal
animationType="slide"
transparent={false}
visible={modal}
onRequestClose={() => setModal(false)}
>
<View style={{ marginTop: 22 }}>
<View>
<Text>This is the modal content</Text>
<Button title="Close" onPress={() => setModal(false)} />
</View>
</View>
</Modal>
</View>
);
};
I actually found what i had been looking for. I just had to write the following code:
{returnResults(a,b,c)}
I'm creating an app with React Native & Expo.
One of the search inputs includes an icon, so I did it like so:
<View style={styles.inputContainer}>
<FontAwesome name="search" size={20} color="black" />
<TextInput
style={styles.input}
value={search}
placeholder="Pesquise"
placeholderTextColor={text_gray}
onChangeText={(text) => setSearch(text)}
/>
</View>
But the Keyboard shows only when I click the TextInput, and I need to open it wherever I click the View that wraps it and the icon.
How can I achieve that?
Create a ref to the TextInput and then call REF.current.focus() to focus on the textInput and REF.current.blur() to blur it. Use Pressable instead of View, its just like a View but with different onPress events.
const textInput = useRef(null);
return (
<Pressable style={styles.inputContainer} onPress={() => textInput?.current?.focus()}>
<FontAwesome name="search" size={20} color="black" />
<TextInput
ref={textInput}
style={styles.input}
value={search}
placeholder="Pesquise"
placeholderTextColor={text_gray}
onChangeText={(text) => setSearch(text)}
/>
</Pressable>
)
I have a number of TextInput in my react-native application and I want that if user clicks on next key, the next input must be focused. I am trying to do this with returnKeyType prop passed to all the TextInput. However this doesn't work as intended ,i.e. next input is not focused. And my code for same looks like
<TextInput
ref={firstInputForDaysInterestTextInputRef}
value={closingCosts.firstInputForDaysInterest}
onChangeText={value =>
onStateChange('firstInputForDaysInterest', value)
}
onEndEditing={event =>
onEndEditing(
'firstInputForDaysInterest',
event.nativeEvent.text,
)
}
placeholderTextColor={colors.placeholderColor}
placeholder={constants.common.zeroPlaceholder}
autoCapitalize="none"
returnKeyType="next"
onFocus={() => onFocus(elementName)}
keyboardType="decimal-pad"
style={[
styles.textInput,
styles.textInputWidth,
styles.textInputMargin,
]}
/>
The workaround that I thought was passing ref and then focusing the next input onEndEditing, but if I does this the textinput will not be closed when I tap outside the textInput. So how can I make my text input to focus on next one?
You can use onSubmitEditing prop to focus the next input for example:
const firstInputForDaysInterestTextInputRef = React.useRef()
const secondInputForDaysInterestTextInputRef = React.useRef()
return (
<View style={styles.container}>
<TextInput
ref={firstInputForDaysInterestTextInputRef}
placeholderTextColor={'gray'}
placeholder={'first'}
autoCapitalize="none"
returnKeyType="next"
keyboardType="decimal-pad"
onSubmitEditing={()=>secondInputForDaysInterestTextInputRef.current?.focus()}
style={[
styles.textInput,
styles.textInputWidth,
styles.textInputMargin,
]}
/>
<TextInput
ref={secondInputForDaysInterestTextInputRef}
placeholderTextColor={'gray'}
placeholder={'second'}
autoCapitalize="none"
returnKeyType="next"
onFocus={() => alert('I am focused !')}
keyboardType="decimal-pad"
style={[
styles.textInput,
styles.textInputWidth,
styles.textInputMargin,
]}
/>
</View>
);
Example on Snack
If you want to hide the textinput (hide keyboard) when pressing somewhere else in the app, wrap it it like this for example:
<TouchableWithoutFeedback onPress={Keyboard.dismiss}>
<View style={styles.container}>
<TextInput />
</View>
</TouchableWithoutFeedback>
Don't forget to import TouchableWithoutFeedback and Keyboard from 'react-native'
I am a beginner at React Native. When I try to type a text in a Text Input box, I'm not able to type, because the keyboard hides within 2 seconds. I don't know why this happens, here is my code, kindly solve this issue, this issue only occurs on Android devices.
Here is my code,
render() {
return (
<View style={styles.container1}>
<ScrollView>
<View style={styles.container}>
<View style={styles.SectionStyle}>
<Image source={require('../assets/padlock.png')} style={styles.ImageStyle} />
<TextInput
style={{flex:1}}
placeholder="Current Password"
underlineColorAndroid="transparent"
secureTextEntry
selectionColor={'#002B60'}
returnKeyType={'next'}
blurOnSubmit={false}
onSubmitEditing={() => this.passwordRef.focus()}
onChangeText={(oldpassword) => this.setState({oldpassword})}
/>
</View> </View>
</View>
</ScrollView>
</View>
);
}
}
This is kind of what I want to achieve in my react native app. How should I go about it?
this is just an idea to show or hide a TextInput upon button press
return (
<View>
<TouchableOpacity onPress={() => this.setState({show : !this.state.show})}>
<Text>Click Here</Text>
</TouchableOpacity>
{this.state.show ? <TextInput
Value={this.state.value}
onChangeText={value => this.setState({value})}
/>
: null}
</View>
);
Initialize this.state.show as either true or false according to your requirement.
