A complete guide to TextInput in React Native

Consider a situation where you want to retrieve a user’s login credentials. For this use case, it would be appropriate to have a component that allows the client to enter text data in your app.

This is where React Native’s component comes in. Apart from strings, we can even customize it to accept passwords and numbers.

In this article, you will learn the basics of React Native’s component. Later on, we will also tailor its properties according to our needs.

This will be the outcome of this guide:

A Basic RN TextInput

Getting Started

To materialize an app with Expo, run the following terminal command:

expo init textinput-tutorial

Within your project directory, install the dependency like so:

npm install react-native-paper

Simple usage

The following code snippet renders a basic text box:

import { StyleSheet, Text, View, TextInput } from "react-native"; export default function App() { return ( <View style={styles.container}> <TextInput style={styles.input} /> </View> ); } const styles = StyleSheet.create({ input: { backgroundColor: "white" }, //... });

Simple Text Box in RN

You can make your element look even better like so:

const styles = StyleSheet.create({ input: { borderColor: "gray", width: "100%", borderWidth: 1, borderRadius: 10, padding: 10, }, });

In the piece of code above, we styled the text box’s border and gave it some padding. Furthermore, we used the property. This tells React to add rounded borders.

TextInput BorderRadius in RN

It definitely looks more attractive now!

Customization

Adding a placeholder

Adding a placeholder is useful when you want to provide hints and instructions to help the user fill in data.
To do so, use the prop:

<TextInput style={styles.input} placeholder="John" />

Placeholder TextInput RN

Multiple lines

The component can also accept multi-line text. This can be useful for cases like acquiring user feedback:

<TextInput style={styles.input} multiline={true} />

Multiple Lines for TextInput

Maximum length

Want to restrict the user’s input length? This can be possible with the prop:

<TextInput style={styles.input} maxLength={4} />

Maximum Length for TextInput RN

Unalterable text box

You can block input to your element using the prop:

<TextInput style={styles.input} editable={false} value="This cannot be edited" />

Unalterable Text Box RN

Changing keyboard types

Consider a circumstance where you’re asking for the client’s phone number. Here, it would be sensible to show the numerical keyboard instead of the default one.

To change keyboard types, use like so:

<TextInput style={styles.input} keyboardType="phone-pad"/>

Phone Pad for TextInput

To get the user’s email address, the appropriate woud be :

<TextInput style={styles.input} keyboardType="email-address"/>

Email Address Pad for TextInput

Getting passwords

When it comes to passwords, we can customize our text field so that the entered data is obscured. To achieve this, we will use the property like so:

<TextInput style={styles.input} secureTextEntry={true}/>

Secure Text Entry for TextInput

Recording a user’s input

After every text change

Let’s say you have a text box that functions as a search bar. In such a circumstance, you would want to capture the data every time the input’s value changes.

You can achieve this via the prop. It is a callback that runs whenever the text field detects a change:

export default function App() { const [name, setName] = useState(""); return ( <View style={styles.container}> <Text>Write name.</Text> <TextInput style={styles.input} placeholder="John Doe" onChangeText={(value) => setName(value)} /> <Text>Welcome: {name}</Text> </View> ); }

In this code, we told React Native to update the Hook to the value of . In the end, we displayed the value of the variable.

Record Every Input Change with TextInput

When a user submits

Consider a situation where you have a form and want to save data only if the user submits the form.

To make this possible, you can use the callback:

export default function App() { const [name, setName] = useState(""); return ( <View style={styles.container}> <Text>Write name.</Text> <TextInput style={styles.input} onSubmitEditing={(value) => setName(value.nativeEvent.text)} /> <Text>Welcome, {name}!</Text> </View> ); }

In the above piece of code, React Native updates the Hook variable to the input value if the user presses the return key.

Record Submitted Inputs with TextInput

Text field icons with React Native Paper

React Native Paper allows us to display icons on any side of the text box. This will make your interface look more modern.
The following code snippet renders a graphic with the text field:

import { TextInput } from "react-native-paper"; //extra code removed... return ( <View> <Text> Please enter your credentials</Text> <TextInput label="Username" left={<TextInput.Icon name="account" />} /> <TextInput label="Password" secureTextEntry left={<TextInput.Icon name="form-textbox-password" />} /> </View> );

The property tells React Native to display the desired icon on the left.
This will be the output:

Final Product for TextInput

Conclusion

In this guide, you learned how to use and record in the React Native library. In my own apps, I use React Native Paper because it looks good on all platforms out of the box.

Style text react native input

TextInput

A foundational component for inputting text into the app via a keyboard. Props provide configurability for several features, such as auto-correction, auto-capitalization, placeholder text, and different keyboard types, such as a numeric keypad.

The most basic use case is to plop down a and subscribe to the events to read the user input. There are also other events, such as and that can be subscribed to. A minimal example:

Two methods exposed via the native element are .focus() and .blur() that will focus or blur the TextInput programmatically.

Note that some props are only available with . Additionally, border styles that apply to only one side of the element (e.g., , , etc.) will not be applied if . To achieve the same effect, you can wrap your in a :

has by default a border at the bottom of its view. This border has its padding set by the background image provided by the system, and it cannot be changed. Solutions to avoid this are to either not set height explicitly, in which case the system will take care of displaying the border in the correct position, or to not display the border by setting to transparent.

Note that on Android performing text selection in an input can change the app's activity param to . This may cause issues with components that have position: 'absolute' while the keyboard is active. To avoid this behavior either specify in AndroidManifest.xml ( https://developer.android.com/guide/topics/manifest/activity-element.html ) or control this param programmatically with native code.

                In this chapter, we will show you how to work with TextInput elements in React Native.

                The Home component will import and render inputs.

                App.js

                import React from 'react'; import Inputs from './inputs.js' const App = () => { return ( <Inputs /> ) } export default App

                Inputs

                We will define the initial state.

                After defining the initial state, we will create the handleEmail and the handlePassword functions. These functions are used for updating state.

                The login() function will just alert the current value of the state.

                We will also add some other properties to text inputs to disable auto capitalisation, remove the bottom border on Android devices and set a placeholder.

                inputs.js

                import React, { Component } from 'react' import { View, Text, TouchableOpacity, TextInput, StyleSheet } from 'react-native' class Inputs extends Component { state = { email: '', password: '' } handleEmail = (text) => { this.setState({ email: text }) } handlePassword = (text) => { this.setState({ password: text }) } login = (email, pass) => { alert('email: ' + email + ' password: ' + pass) } render() { return ( <View style = {styles.container}> <TextInput style = {styles.input} underlineColorAndroid = "transparent" placeholder = "Email" placeholderTextColor = "#9a73ef" autoCapitalize = "none" onChangeText = {this.handleEmail}/> <TextInput style = {styles.input} underlineColorAndroid = "transparent" placeholder = "Password" placeholderTextColor = "#9a73ef" autoCapitalize = "none" onChangeText = {this.handlePassword}/> <TouchableOpacity style = {styles.submitButton} onPress = { () => this.login(this.state.email, this.state.password) }> <Text style = {styles.submitButtonText}> Submit </Text> </TouchableOpacity> </View> ) } } export default Inputs const styles = StyleSheet.create({ container: { paddingTop: 23 }, input: { margin: 15, height: 40, borderColor: '#7a42f4', borderWidth: 1 }, submitButton: { backgroundColor: '#7a42f4', padding: 10, margin: 15, height: 40, }, submitButtonText:{ color: 'white' } })

                Whenever we type in one of the input fields, the state will be updated. When we click on the Submit button, text from inputs will be shown inside the dialog box.

                TextInput is the fundamental component to input text. It has several props which configure the different features, such as onChangeText that takes a function and call it whenever the text changed. The onSubmitEditing prop takes a function, which is called when the text submitted.

                There are several things, which can be performed with text input, such as validating the text inside while user types.

                React Native TextInput Example 1

                In this example, we create a TextInput and perform an onChangeText action. At every text change, it calls the setState and checks the condition of a split. If the input text found ' ' space, it displays '🍕' in the text. The text is placed in state as it is changed every time.

                The method .focus() and .blur() are exposed from the native element. These methods focus or blur the TextInput programmatically.

                Multiline TextInput

                The multiline props provide facility to input multiple lines of text. Some props of TextInput are only compatible with multiline, for example, multiline={true/false}. The property borderButtomColor will not work if multiline = false.
