React Native Text Input fixed text - react-native

I want to add something like a Hint, on the textInput, as in java using android studio, in react native is it possible to do this? I know you have the option to add a Value, defaultValue and the placeholder, but they don't work like hint.
Tanks!

You can use placeholder props
<TextInput
placeholder="Input email"
/>

Yes it is possible, it's called placeholder, Here is an example from docs.:
<TextInput
style={{height: 40}}
placeholder="Type here to translate!"
onChangeText={(text) => this.setState({text})}
value={this.state.text}
/>

The only thing you need to do is to add a the placeholder prop.
<TextInput
...//otherprops
placeholder="enter your hint here"
/>
I highly suggest you to read more about TextInput in React Native docs here

Is there a any way to get the text value of the TextInput using ref in react native?

I am getting the text of the TextInput using onChangeText event and state.
<View style={styles.inputContainerStyle}>
<TextInput
autoFoucs={true}
ref={inputRef}
style={styles.textInputStyle}
placeholder="type here ..."
placeholderTextColor='#838389'
multiline
underlineColorAndroid="transparent"
onChangeText={text => handleTextChange(text)}
value={selectedText}
/>
<TouchableOpacity style={styles.submitBtnWrapperStyle} onPress={() => handleMsgSend()}>
<Icon name={msgEditMode ? "check" : "paper-plane"} size={20} color="#ffffff" />
</TouchableOpacity>
</View>
...
// handle text change on textinput
const handleTextChange = text => {
channel && channel.typing();
setSelectedText(text);
}
But actually whenever text is changed, the render function also is called because of changing state value and it is making the whole screen more slow.
So I am looking for the alternative way to get the text not using onChangeText event.
Is there any native way to get the text using ref?
I hope kind help.
thanks...
Yes, you can access the value of text input using ref like this
this.inputRef._lastNativeText

How to make the placeholder text uppercase in React Native?

I want to change the placeholder in TextInput to uppercase without affecting the input. I intend to keep the input in lowercase. How do I achieve that?
Did you try to write placeholder value uppercase like below?
<TextInput
placeholder={'TEST'}
onChangeText={(text) => this.setState({ text })}
value={text}
style={styles.input}
/>
If you want to change placeholder case then use javascript functions e.g.toUpperCase() as below:
<TextInput
placeholder={String('test').toUpperCase()}
onChangeText={(text) => this.setState({ text })}
value={text}
style={styles.input}
/>

How to disable keyboard in react native

I created a screen keyboard component that I want to disable the platform's keyboard, how I can disable it?
<TextInput
secureTextEntry
ref="Pin"
selectionColor="#656565"
keyboardType="numeric"
activeColor="#656565"
inactiveColor="#fff"
autoFocus={false}
ignoreCase
codeLength={4}
inputPosition="center"
size={50}
onFulfill={isValid => this}
codeInputStyle={{ borderWidth: 1.5 }}
/>
Just write showSoftInputOnFocus={false} in <TextInput> like this:
<TextInput showSoftInputOnFocus={false} />
I had issues also. No other solutions was working for me. This will display text input field and it will be clickable but not editable.
<TouchableOpacity onPress={this.openPinKeyboard}>
<View pointerEvents="none">
<Input editable={false} value="1234" />
</View>
</TouchableOpacity>
I think you need to add something like:
<TextInput showSoftInputOnFocus={false} keyboardType="numeric" />
setting keyboardType to null worked for me
EDIT:
this only worked in the simulator, running it on an actual device the native keyboard still appeared.
wrapping the <TextInput /> in a <TouchableWithoutFeedback> element in the example below worked.
<TouchableWithoutFeedback onPress={Keyboard.dismiss} >
<TextInput />
</TouchableWithoutFeedback>
You may try to set keyboardType to none, if it doesn't work another alternative is to set the editable prop to false.
Potential answers can be found here : https://github.com/facebook/react-native/issues/14045
<TextInput showSoftInputOnFocus={false}/>
This work for me, sometime I need onFocus action to navigate new screen, and don't need keyboard open animation. Prop Editable will disable textfield, can not pressable
try this solution i hope this will work for android and ios both...
// Step 1: Get Keyboard, TouchableWithoutFeedback from ‘react-native’;
import { View, TextInput, StyleSheet, Keyboard, TouchableWithoutFeedback } from 'react-native';
// Step 2: Create an arrow function to write dismiss keyboard code
const DismissKeyboard = ({ children }) => (
<TouchableWithoutFeedback onPress={() => Keyboard.dismiss()}>
{children}
</TouchableWithoutFeedback>
);
// Step 3: Wrap all TextInput inside <DismissKeyboard> </DismissKeyboard>
//Example
<DismissKeyboard>
<View style={styles.container}>
<TextInput style={styles.input} placeholder="email" />
<TextInput style={styles.input} placeholder="password" />
</View>
</DismissKeyboard>
The easiest solution is to use the onFocus prop on TextInput.
Import Keyboard from ‘react-native’
import {Keyboard, TextInput} from
'react-native'
Then pass Keyboard.dismiss() to TextInput onFocus prop, to stop the keyboard from popping up when focused.
<TextInput onFocus = {()=> Keyboard.dismiss()} .../>
Now test the input field by pressing it to see if the keyboard will pop up
just put this under text input tag this worked for me in react-native
<TextInput
//this line
editable={false}
/>
you can do it by pointerEvents="none"
<View pointerEvents="none">
<TextInput
focusable={false}
style={{color: '#00000000'}}
onChangeText={setEmail}
/>
</View>

TextInput unwanted Underline

I'm working on a project which has some text fields(textInput). I'm encountering an issue with the textInput fields here. While I type in the textInput field the text is having an underline which is getting even more darker when I hit space and I want to remove that underline from it.
Here is a screenshot:
This is my code:
<TextInput
style={Style.InputStyle}
multiline={true}
placeholderTextColor={'#DC1938'}
placeholder={'Name'}
spellCheck={false}
underlineColorAndroid='rgba(255,0,0,0.3)'
inlineImageLeft='userred'
inlineImagePadding={25}
padding={15}
/>
Try Following props.
spellCheck={false}
autoCorrect={false}
Please refer the following link :
disable spellcheck in react-native TextInput
Hello guys i have found the answer it was the autoCorrect prop. i disabled it and yeah it worked!
Use underlineColorAndroid props
<TextInput underlineColorAndroid='transparent'
placeholder="type here ..">
This is some text you want to render
</TextInput>
An explanation why this happens can be found here.

i want keyboard not to show up at all when i touch my text input-React-Native

I want keyboard not to show up at all when i touch my text input.If i use 'Keyboard.dismiss' i loose the focus on my text input i am using custom keyboard which itself is part of my screen so i don't want any keyboard to show up at all without loosing the focus on my text input, any solution please.I have tried using libraries but facing same problems again and again what should i do. Here the code i Am using
<TextInput onFocus={Keyboard.dismiss}>
Use <TextInput showSoftInputOnFocus={false} />
It will hide the keyboard when you focus on the text input.
ReactNative TextInput has showSoftInputOnFocus prop, which is due to docs should hide keyboard. But seems like it doesn't work.
I found this solution, works for me:
<>
<TouchableWithoutFeedback onPress={this.toggleVisible}>
<View>
<View pointerEvents="none">
<Input
value={String(value)}
placeholder={placeholder}
/>
</View>
</View>
</TouchableWithoutFeedback>
<DateTimePicker
isVisible={this.state.visible}
onConfirm={onChange}
onCancel={this.toggleVisible}
/>
Correct way is to encapsulate View with keyboard is calling Keyboard.dismiss()
you should use TouchableWithoutFeedback so that on clicking it should disable
the keyboard
<TouchableWithoutFeedback onPress={Keyboard.dismiss}>
<TextInput keyboardType='numeric'/>
</TouchableWithoutFeedback>
Try this may be it can solve the problem
