disable text input after entering some input value in react native - react-native

This is the text input that I am using, I want the input field to be disabled after entering a value.I tried using editable props, but it did not help.
I am completely new to react native, please help with an example.
<View style={editProfileStyle.textinputView}>
<TextInput
style={editProfileStyle.textInput}
placeholder="Enter your Specialization"
value={this.state.subQualification}
onChangeText={subQualification => this.setState({ subQualification: subQualification })}
/>
</View>

As per the question, since the field should get disabled when it has some value:
<View style={editProfileStyle.textinputView}>
<TextInput
editable={this.state.subQualification.length === 0}
style={editProfileStyle.textInput}
placeholder="Enter your Specialization"
value={this.state.subQualification}
onChangeText={subQualification => this.setState({ subQualification: subQualification })}
/>
</View>
using check in your editable prop of
editable={this.state.subQualification.length === 0} will make field editable when nothing in present in the field

Try to add state and modify your textInput props like this:
state ={
textDisable: true
}
render() {
return (
<View style={editProfileStyle.textinputView}>
<TextInput
style={editProfileStyle.textInput}
placeholder="Enter your Specialization"
value={this.state.subQualification}
onChangeText={subQualification => this.setState({ subQualification: subQualification })}
editable={this.state.textDisable}
onEndEditing={() => this.setState({textDisable: false})}
/>
</View>
);
}
}
after onsubmit the input should be disable.

React Native TextInput returnKeyType not working

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'

placeholderTextColor={"#313131"}
ref={input => (this.c_pin = input)}

please tell me how to working onsubmitediting
you have to pass text from submit event to the function,
<TextInput
onSubmitEditing={(event) => this.onSubmit(event.nativeEvent.text)}
/>

React native TextInput Component

I search it every day why it doesn't work properly.When I type anything onto TextInput's placeholder it starts with empty space.I want to start without space.I also tried trim() method.It wasn't helpful.How should I fix my error? Thanks in advance!
<TextInput value={this.state.key} onChangeText={(text) =>{this.setState({key:text.trim()}) ; console.warn('key: '+this.state.key)}}/>
Try this :
<TextInput
value={this.state.key}
keyboardType="default"
onChangeText={key => this.setState({ key })}
/>;
UPDATED ANSWER :
_replaceSpace(str) {
return str.replace(/\u0020/, '\u00a0')
}
<TextInput
style={{ textAlign: "right" }}
value={this._replaceSpace(this.state.text)}
onChangeText={text => this.setState({ text: text })}
/>;

How to open keyboard on button press in react native?

I have a button and when it is pressed I would like it to open the keyboard and focus on a text input component.
For a minimal code example what I am trying to do is this-
<View>
<AddSomething
textChange={textInput => this.setState({ textInput })}
addNewItem={this.addItem.bind(this)}
textInput={this.state.textInput}
ref={not sure what goes here} //passing these as props to a text input
/>
<FloatingButton tapToAddHandler={this.onFloatingButtonPress.bind(this)} />
</View>
then some helper function where I handle the button press (this.onFloatingButtonPress)
First declare your AddSomething as below :
const AddSomething = React.forwardRef((props, ref) => (
<TextInput
ref={ref}
//your other code
/>
));
Now you can use ref and able to focus your AddSomething component as below:
<View>
<AddSomething
textChange={textInput => this.setState({ textInput })}
addNewItem={this.addItem.bind(this)}
textInput={this.state.textInput}
ref={(ref) => { this.textInputField = ref }}
/>
<FloatingButton tapToAddHandler={this.onFloatingButtonPress.bind(this)} />
</View>
Here is your onFloatingButtonPress method :
onFloatingButtonPress() {
this.textInputField.focus();
}
Proposal a react-hook version :
const inputRef = React.useRef()
return (
<TextInput ref={inputRef} />
<TouchableOpacity onPress={() => inputRef.current.focus()}>
<Text>Press</Text>
</TouchableOpacity>
)

React Native : TextInput loosing text when style changes

I have a TextInput whose style changes according to a state.
<TextInput
autoCapitalize="characters"
defaultValue={this.props.name}
onChangeText={(text) => { this.handleChangeText(text); }}
onEndEditing={this.handleTextSubmit}
placeholder={this.props.dictionary.Identification__placeholder}
placeholderTextColor={color.WHITE}
ref={(component) => { this.textInput = component; }}
style={[
defaultStyles.input,
styles.input,
this.state.keyboardIsVisible && styles.inputSelected,
]}
underlineColorAndroid="rgba(0,0,0,0)"
/>
The problem is that when the style changes, it erases the current value in the TextInput. Is there a way to fix this behavior ?
What is handleTextChange doing? you should have a value property like value={this.state.inputText} and have handleTextChange update that value.
