I´m confused with this whole "no CSS" thing, but I understand why it's beneficial. All I want to do is place a button in the middle of the screen but I don't understand how styling works in React yet. This is my code:
var tapSpeed = React.createClass({
render: function() {
return (
<View style={styles.container}>
<Text style={styles.welcome}>
Tap me as fast as you can!
</Text>
<View style={styles.button}>
!
</View>
</View>
);
}
});
var styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#FFCCCC'
},
welcome: {
fontSize: 20,
textAlign: 'center',
margin: 10
},
button: {
textAlign: 'center',
color: '#ffffff',
marginBottom: 7,
border: 1px solid blue,
borderRadius: 2px
}
});
Update: use built-in Button component.
Deprecated:
Wrap your View into TouchableHighlight for iOS and TouchableNativeFeedback for Android.
var {
Platform,
TouchableHighlight,
TouchableNativeFeedback
} = React;
var tapSpeed = React.createClass({
buttonClicked: function() {
console.log('button clicked');
},
render: function() {
var TouchableElement = TouchableHighlight;
if (Platform.OS === 'android') {
TouchableElement = TouchableNativeFeedback;
}
return (
<View style={styles.container}>
<Text style={styles.welcome}>
Tap me as fast as you can!
</Text>
<TouchableElement
style={styles.button}
onPress={this.buttonClicked.bind(this)}>
<View>
<Text style={styles.buttonText}>Button!</Text>
</View>
</TouchableElement>
</View>
);
}
});
You can use built in react-native Button element.
import React, { Component } from 'react';
import { StyleSheet, View, Button, Alert, AppRegistry } from 'react-native';
class MainApp extends Component {
_onPress() {
Alert.alert('on Press!');
}
render() {
return (
<View style={styles.container}>
<View style={styles.buttonContainer}>
<Button onPress={this._onPress} title="Hello" color="#FFFFFF" accessibilityLabel="Tap on Me"/>
</View>
</View>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#FFFFFF'
},
buttonContainer: {
backgroundColor: '#2E9298',
borderRadius: 10,
padding: 10,
shadowColor: '#000000',
shadowOffset: {
width: 0,
height: 3
},
shadowRadius: 10,
shadowOpacity: 0.25
}
})
AppRegistry.registerComponent('MainApp', () => MainApp);

The react-native-button package provides a button that is styled like a native button. Install it with npm install react-native-button and use it in your component like this:
var Button = require('react-native-button');
var ExampleComponent = React.createClass({
render() {
return (
<Button
style={{borderWidth: 1, borderColor: 'blue'}}
onPress={this._handlePress}>
Press Me!
</Button>
);
},
_handlePress(event) {
console.log('Pressed!');
},
});
You have two options to achieve a touchable component/button to handle user's events.
One is to use the built in Button Component. Check the docs here http://facebook.github.io/react-native/docs/button.html
Two use either TouchableHighlight or TouchableNativeFeedback or TouchableOpacity or TouchableWithoutFeedback. Think of this as a way for you to convert different areas of your app to tappable(clickable) or a way for you to create a custom button.
Each component here is different based on how it behaves once it's tapped by the user. Check the docs for more details. http://facebook.github.io/react-native/docs/touchablewithoutfeedback.html etc.
Concerning styling in react native you will need to understand flexbox layout. Check this css flexbox article all rules are applicable to react-native https://css-tricks.com/snippets/css/a-guide-to-flexbox/ except that you will have to capitalize the rules e.g align-content to alignContent
<Button
onPress={onPressLearnMore}
title="Learn More"
color="#841584"
accessibilityLabel="Learn more about this purple button"
/>
Please check react-native doc's regarding the buttons
You have more than one way to add button in your application and styling it
You can use Button tag and it's have only one way styling by color attribute, it will appearing in IOS different than Android, or by putting button in view tag with style
<View style={style.buttonViewStyle}>
<Button title="Facebook" color="blue" onPress={this.onFacebookPress} />
</View>
And check the TouchableOpacity and TouchableNativeFeedback tags
And take a lock on below link for more options to add custom buttons in your app
https://js.coach/react-native/react-native-action-button?search=button
export default class Login extends React.Component {
barcodeAction = () => {
this.props.navigation.navigate('BarCodeScanner')
}
cleverTapAction = () => {
this.props.navigation.navigate('CleverTapApp')
}
}
render() {
return (
<View style={styles.container}>
<View style={styles.buttonContainer}>
<Button
onPress={this._onPressButton}
title="Press Me"
/>
</View>
<View style={styles.buttonContainer}>
<Button
onPress={this._onPressButton}
title="Press Me"
color="#841584"
/>
</View>
<View style={styles.alternativeLayoutButtonContainer}>
<Button
onPress={this._onPressButton}
title="This looks great!"
/>
<Button
onPress={this._onPressButton}
title="OK!"
color="#841584"
/>
</View>
</View>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
},
buttonContainer: {
margin: 20
},
alternativeLayoutButtonContainer: {
margin: 20,
flexDirection: 'row',
justifyContent: 'space-between'
}
});
The Button element from react-native package does not provide built in styling feature. Ex. The "title" props will be in upper case by default. Hence, I've used an another package react-native-elements that provides nice features for Button element along with different styling options.
You can refer more details on Button from react-native-elements
import React, { Component } from 'react';
import { StyleSheet, View, TouchableOpacity, Text} from 'react-native';
var tapSpeed = React.createClass({
render: function() {
return (
<View style={styles.container}>
<TouchableOpacity>
<Text style={styles.welcome}>
Tap me as fast as you can!
</Text>
</TouchableOpacity>
<TouchableOpacity style={styles.button}>
<Text>!</Text>
</TouchableOpacity>
</View>
);
}
});
var styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
flexDirection: 'column',
alignItems: 'center',
backgroundColor: '#FFCCCC'

welcome: {

You can easily create that card with a little bit of CSS.
Below is the sample app which shows you how you can achieve that.
Working Example: Expo Snack
import React, { useState, useEffect } from 'react';
import {
Text,
View,
StyleSheet,
FlatList,
Image,
TouchableOpacity,
} from 'react-native';
import { AntDesign } from '#expo/vector-icons';
import Constants from 'expo-constants';
import { newsFeed } from './news';
export default function App() {
const [news, setNews] = useState(newsFeed);
const showFull = (index) => {
const temp = [...news];
temp[index].toggle = !temp[index].toggle;
setNews(temp);
};
return (
<View style={styles.container}>
<FlatList
data={news}
renderItem={({ item, index }) => (
<View style={styles.card}>
<Text style={styles.title}>{item.title}</Text>
<Text style={styles.paragraph}>
{item.toggle ? item.desc : `${item.desc.substr(0, 100)}...`}
</Text>
{item.toggle && (
<Image source={{ uri: item.img }} style={styles.img} />
)}
<View style={styles.bottomBar}>
<Text style={styles.date}>4/02/2021</Text>
<TouchableOpacity onPress={() => showFull(index)}>
<View style={{ flexDirection: 'row', alignItems: 'center' }}>
<Text style={styles.moreBtn}>
{!item.toggle ? 'More' : 'Less'}
</Text>
<AntDesign
name={item.toggle ? 'up' : 'down'}
size={12}
color="orange"
/>
</View>
</TouchableOpacity>
</View>
</View>
)}
/>
</View>
);
}
const styles = StyleSheet.create({
bottomBar: {
marginVertical: 5,
flexDirection: 'row',
justifyContent: 'space-between',
},
container: {
flex: 1,
justifyContent: 'center',
paddingTop: Constants.statusBarHeight,
backgroundColor: '#ecf0f1',
padding: 8,
},
card: {
padding: 10,
backgroundColor: 'white',
marginVertical: 5,
borderRadius: 10,
},
title: {
marginVertical: 5,
fontSize: 18,
fontWeight: 'bold',
},
img: {
flex: 1,
height: 100,
borderRadius: 10,
marginVertical: 5,
},
paragraph: {
fontSize: 14,
},
date: {
fontSize: 12,
color: 'rgba(21,21,21,0.5)',
},
moreBtn: {
fontSize: 12,
color: 'orange',
marginRight: 10,
},
});
actually this card is not a component you can design it using css and if you want to create a component which you can reuse then you can make one component and reuse it as you want and for this card either you can use your own css or a library called native-base which is
like bootstrap but it is used in react-native
you can read about native base here for more information
https://nativebase.io/
and if you want to create card of your own then make a separate file and make a funcional card component in it
and call it wherever you like
import myCustomCard from './card'
and to use it you use like this in your jsx
<myCustomCard />
and if you want to know more about how to pass props and else you can checkout official docs of the react native here
https://reactnative.dev/docs/getting-started
I am new to React Native and I have encountered a problem: my TextBox doesn't stay above the keyboard while I am writing in it.
These are the visuals from the application
Screenshot
And this is my Signup.js:
import React, { Component } from 'react';
import {
StyleSheet,
Text,
View,
TouchableOpacity
} from 'react-native';
import Form from '../components/Form';
import Logo2 from'../components/Logo2';
import {Actions} from 'react-native-router-flux';
export default class Signup extends Component {
goBack() {
Actions.pop()
}
render() {
return(
<View style={styles.container}>
<Logo2/>
<Form type="Registrar"/>
<View style={styles.signupTextCont}>
<Text style={styles.signupText}>Ja tens uma conta? </Text>
<TouchableOpacity onPress={this.goBack}><Text style={styles.signupButton}>Entra</Text></TouchableOpacity>
</View>
</View>
)
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#232122'
},
signupTextCont: {
flexGrow: 1,
justifyContent: 'center',
alignItems: 'flex-end',
paddingVertical: 16,
flexDirection: 'row'
},
signupText: {
color: 'rgba(255,255,255,0.7)',
fontSize:16
},
signupButton: {
color: '#FFA200',
fontSize:16,
fontWeight: '500'
}
});
I don't know what I need to code.
Could you please help me?
To replicate my comment that resolved your problem; you can use the component KeyboardAvoidingView from the package react-native. It levels up the area it contains above your virtual keyboard.
Wrap your code like this:
<KeyboardAvoidingView behavior={'position'} enabled>
<View style={styles.signupTextCont}>
<Text style={styles.signupText}>Ja tens uma conta? </Text>
<TouchableOpacity onPress={this.goBack}>
<Text style={styles.signupButton}>Entra</Text>
</TouchableOpacity>
</View>
</KeyboardAvoidingView>
Here's some more info about how it works: https://facebook.github.io/react-native/docs/keyboardavoidingview.
You can wrap your code with KeyboardAvoidingView rather than a normal View so that it can actually lift up any items inside it above the keyboard. You can use <KeyboardAvoidingView behavior="padding">
Hope it helps.
Site display on webview
Current practice, I am creating a browser application using React-native.
Google and other URLs will be displayed. However, the specific site is not displayed, it becomes a white screen.
※The address is https, and that site is displayed properly on PC or real machine Google Chrome.
Does this mean that there is a flaw in the SSL of the site?
please tell me.
We are doing site designation with source = {{uri: 'https://www.google.com/'}} in the code below.

you should give a width a height style to your WebView tag. Try this and let me know.
add this hier in your webView tag style={styles.webViewStyles}, then add the styles below in your StyleSheet. webViewStyles:{height: 100, width: 100}, dont forget the comma before you add the styles in your StyleSheet.
I have a View with few form elements and a button (TouchableHighlight). On clicking the button, an Activity Indicator should be shown as an overlay to the existing view. The Activity Indicator should be centered within the page and the existing view should be slightly blurred to indicate overlay. I tried different options but could not get it to work.
render() {
const { username, password } = this.state;
return (
<View style={styles.container}>
<View style={styles.group}>
<Text style={styles.text}>Username:</Text>
<TextInput
style={styles.input}
onChangeText={this.handleUserNameChange.bind(this)}
value={username}
underlineColorAndroid="transparent"
/>
</View>
<View style={styles.group}>
<Text style={styles.text}>Password:</Text>
<TextInput
style={styles.input}
secureTextEntry={true}
onChangeText={this.handlePasswordChange.bind(this)}
value={password}
underlineColorAndroid="transparent"
/>
</View>
<TouchableHighlight
style={styles.button}
onPress={this.handleLogin.bind(this)}>
<Text style={styles.buttonText}>Logon</Text>
</TouchableHighlight>
</View>
);
}
Existing styles:
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'flex-start',
alignItems: 'center',
backgroundColor: '#F5FCFF',
marginTop: 60
},
group: {
alignItems: 'flex-start',
padding: 10
},
input: {
width: 150,
padding: 2,
paddingLeft: 5,
borderColor: 'gray',
borderWidth: 1
},
text: {
padding: 0
},
button: {
width: 150,
backgroundColor: '#2299F2',
padding: 15,
marginTop: 20,
borderRadius: 5
},
buttonText: {
textAlign: 'center',
color: '#fff',
fontSize: 24
},
});
I need to an ActivityIndicator to the above View, overlay the view, and center the ActivityIndicator.
For this to work, you'd need to absolute position it, and render it after the elements that should be underneath the overlay:
loading: {
position: 'absolute',
left: 0,
right: 0,
top: 0,
bottom: 0,
alignItems: 'center',
justifyContent: 'center'
}
Then simply compose it into the render method conditionally, based on a loading state. I am going to assume this.handleLogin sets some sort of loading state already.
Make sure it's rendered last so it takes precedence.
...
{this.state.loading &&
<View style={styles.loading}>
<ActivityIndicator size='large' />
</View>
}
Here is a complete example using create react native app.
import React from 'react';
import {StyleSheet, ActivityIndicator, View} from "react-native";
export default class Example extends React.Component {
constructor(props) {
super(props);
this.state = {}
render() {
return (
<View
style={{flex: 1}}
>
//Add other content here
{this.state.loading &&
<View style={styles.loading}>
<ActivityIndicator/>
</View>
}
</View>
);
}
}
showLoading() {
this.setState({loading: true})
}
hideLoading() {
this.setState({loading: false})
}
const styles = StyleSheet.create({
loading: {
position: 'absolute',
left: 0,
right: 0,
top: 0,
bottom: 0,
opacity: 0.5,
backgroundColor: 'black',
justifyContent: 'center',
alignItems: 'center'
}
})
You can use StyleSheet.absoluteFill to shorten code.
Add this to your render:
<View style={styles.container}>
//... other code here
{this.state.loading && <View
style={{
...StyleSheet.absoluteFill,
justifyContent: 'center',
alignItems: 'center',
}}>
<ActivityIndicator />
</View>}
</View>
Improvement:
You can also create a Loading component:
Loading.js
import React from 'react';
import {View, ActivityIndicator, StyleSheet} from 'react-native';
export const Loading = ({theme = 'white', size = 'large'}) => {
const color = theme === 'white' ? '#00bdcd' : '#fff';
return (
<View
style={{
...StyleSheet.absoluteFill,
justifyContent: 'center',
alignItems: 'center',
}}>
<ActivityIndicator size={size} color={color} />
</View>
);
};
Then use it anywhere you want
<View style={styles.container}>
//... other code here
// remember to import Loading component
{this.state.loading && <Loading />}
</View>
You can build a nice overlay using the activity indicator component by also leveraging the modal capabilities like Sanaur suggests.
For example you can use the below functional component. You can control it's visibility through the show prop that you can tie to a state in your screen.
An example that you can adapt to your needs.
const ModalActivityIndicator = props => {
const {
show = false,
color = "black",
backgroundColor = "white",
dimLights = 0.6,
loadingMessage = "Doing stuff ..."
} = props;
return (
<Modal transparent={true} animationType="none" visible={show}>
<View
style={{
flex: 1,
alignItems: "center",
justifyContent: "center",
backgroundColor: `rgba(0,0,0,${dimLights})`
}}
>
<View
style={{
padding: 13,
backgroundColor: `${backgroundColor}`,
borderRadius: 13
}}
>
<ActivityIndicator animating={show} color={color} size="large" />
<Text style={{ color: `${color}` }}>{loadingMessage}</Text>
</View>
</View>
</Modal>
);
};
and in your screen, in the render's return, just add it there as a child (please ignore the rest of the code, I put it there for context).
return (
<TouchableWithoutFeedback
onPress={() => {
Keyboard.dismiss();
}}
>
<View style={{ padding: 13, flex: 1}}>
<ModalActivityIndicator show={screenIsWaiting} />
<View
style={{
where screenIsWaiting is just a state, for example
const [screenIsWaiting, setScreenIsWaiting] = useState(false);
To test it you can add a button somewhere,
<Button
title="TestButton"
onPress={async () => {
setScreenIsWaiting(true);
await sleep(5000);
setScreenIsWaiting(false);
...
}}
/>
where sleep is a function defined as
function sleep(ms) {
return new Promise(resolve => setTimeout(resolve, ms));
}
I found the sleep() idea on stackoverflow on another post.
You can of course also define the
<ModalActivityIndicator show={screenIsWaiting} ... />
only once in your App's root component and trigger it's display and props via a global state container like redux.
There is a library available for this react-native-loading-spinner-overlay.
You can simply install it using
npm install react-native-loading-spinner-overlay --save
and can import into your project using
import Spinner from 'react-native-loading-spinner-overlay';
Here is how to use it
<Spinner
//visibility of Overlay Loading Spinner
visible={this.state.loading}
//Text with the Spinner
textContent={'Loading...'}
//Text style of the Spinner Text
textStyle={styles.spinnerTextStyle}
/>
STEP 1:
Create the component for the spinner:
export const OverlaySpinner = () => {
return (
<View style={styles.spinnerView}>
<ActivityIndicator size="large" color="#0000ff" />
</View>
);
};
STEP 2:
Create the style for the spinner view (using zIndex is very important to make sure the view is over everything on the screen):
spinnerView: {
position: "absolute",
zIndex: 1,
left: 0,
right: 0,
top: 0,
bottom: 0,
alignItems: "center",
justifyContent: "center",
backgroundColor: "#F5FCFF88",
},
STEP 3:
Make the initial state for the spinning component:
const [showSpinner, setshowSpinner] = useState(true);
STEP 4:
Use the component and don't forget to import it (don't forget to dismiss the keyboard on submit)
{showSpinner && <OverlaySpinner />}
I suppose you should use Modal to overlay activity indicator. Following is an example:
<Modal
transparent={true}
animationType={'none'}
visible={loading}
onRequestClose={() => {console.log('close modal')}}>
<View style={styles.modalBackground}>
<View style={styles.activityIndicatorWrapper}>
<ActivityIndicator
animating={loading} />
</View>
</View>
</Modal>
Add in view of loading
position: 'absolute',
left: 0,
right: 0,
top: 0,
bottom: 0,
alignItems: 'center',
justifyContent: 'center'
set in View of Activity Indicator
position: 'absolute',
left: 0,
right: 0,
top: 0,
bottom: 0,
alignItems: 'center',
justifyContent: 'center'
Here my code for a functional component for anyone looking to achieve this with nativebase as design system. useColorScheme is another hook I use for detecting dark mode.
import { Flex, Spinner } from "native-base"
import React from "react"
import useColorScheme from "../../hooks/useColorScheme"
export default function Loading() {
const colorScheme = useColorScheme()
return (
<Flex
position="absolute"
alignItems="center"
justifyContent="center"
top={0}
left={0}
right={0}
bottom={0}
backgroundColor={colorScheme === "dark" ? "coolBlack.500" : "white"}
>
<Spinner size="lg" color={colorScheme === "dark" ? "white" : "coolBlack.500"} />
</Flex>
)
}
I have a disappearing header which I want to bring back into the view on a single tap anywhere on the screen. But if I am wrapping the entire <View> inside a <TouchableX> component the PanResponder stops working. Is there a hack around this?
You do not need to warp it with Touchable component.
Add next props to root View.
onResponderGrant - make View handle touch
onStartShouldSetResponder - make View handle start
To elaborate #Nicholas Chong advice, here is the example that works for me fine. You can use onTouchStart and onTouchEnd handlers on any View via props:
<View
onTouchStart={() => doSomething()}
style={{ width: '100%', height: '100%' }}
/>
More information
onResponderGrant not working for me, and I use onTouchEnd to trigger when tap the screen, this will work
This would be an example of a implementation with a onResponderGrant
import React, { Component } from 'react';
import {
Platform,
StyleSheet,
Text,
View,
TouchableOpacity
} from 'react-native';
const instructions = Platform.select({
ios: 'Press Cmd+R to reload,\n' +
'Cmd+D or shake for dev menu',
android: 'Double tap R on your keyboard to reload,\n' +
'Shake or press menu button for dev menu',
});
export default class App extends Component<{}> {
constructor() {
super();
this.startTouch = this.startTouch.bind(this);
this.stopTouch = this.stopTouch.bind(this);
this.onTouchE = this.onTouchE.bind(this);
}
startTouch() {
console.debug("You start so don't stop!??");
}
stopTouch() {
console.debug("Why you stop??");
}
onTouchE() {
console.debug("Touchable Opacity is working!!");
}
render() {
return (
<View style={styles.container}
onResponderGrant = { () => this.startTouch() }
onResponderRelease = { () => this.stopTouch() }
onStartShouldSetResponder = { (e) => {return true} }
>
<TouchableOpacity
onPress = { () => this.onTouchE() }

I have included an example of using onResponderGrant and onStartShouldSetResponder inside of a View component.
(Thanks to your previously written answer, #Mr Br)
Definitions
import { Modal, Text, View } from "react-native";
import { useState } from "react";
const [visible, setVisible] = useState(false);
const dismissFunction = () => setVisible(false);
Presentation
<Modal visible={visible} transparent style={{ alignItems: "center", height: "100%", }} >
<View onResponderGrant={dismissFunction} onStartShouldSetResponder={dismissFunction} style={{ flex: 1, backgroundColor: "#1c1c1c75", flexDirection: "column", justifyContent: "flex-end", alignItems: "center" }} >
<View style={{ backgroundColor: "#1E2124", borderRadius: 30, justifyContent: "center", alignItems: "center", height: "30%", shadowColor: "#ffffff10", shadowOpacity: 10, shadowOffset: { width: 0, height: -5 }, width: "101%" }}>
<Text style={{ textAlign: "center", color: "#ffffff", fontSize: 24, marginLeft: "10%", marginRight: "10%", marginBottom: "10%", marginTop: "5%" }}>The message of your modal!</Text>
</View>
</View>
</Modal>
Don't forget to run setVisible(true) somewhere to get the modal to show!
