How can we create Side Tabs in React Native - reactjs

Creating Side Menu in React Application.
This would work both with Expo and react

Create a Navigation Service(Navigation-service.ts)
import { NavigationActions } from 'react-navigation';
function navigate(routeName: any, params?: any) {
NavigationActions.navigate({
routeName,
params
});
setRoute(routeName);
}
export default {
navigate
}
After this
create a new file sidemnu.tsx
import NavigationService from Navigation-service.ts;
import { View, TouchableHighlight, Image } from 'react-native';
openHome() {
NavigationService.navigate('Home');
}
render(){
return (
<View style={[this.props.isLoggedIn ? styles.container : styles.containerHidden]}>
<View style={[this.props.isLoggedIn ? styles.tabContainer : styles.tabContainerHidden]}>
<View>
<TouchableHighlight
style={this.props.currentTab === 'Home' ? styles.activeTab : styles.menuBtnContainer}
onPress={() => this.openHome()}
disabled={!this.props.isLoggedIn}
underlayColor='red'
>
<Image
source='any image url'
/>
</TouchableHighlight>
</View>
</View>
</View>
);
}
Add style
import { StyleSheet } from 'react-native';
const styles = StyleSheet.create({
container: {
width: 108,
backgroundColor: '#002A5C',
borderTopColor: '#002457',
borderWidth: 1
},
containerHidden: {
width: 108,
backgroundColor: '#002A5C'
},
tabContainer: {
flex: 1,
flexDirection: 'column'
},
tabContainerHidden: {
flex: 1,
display: 'none'
},
activeTab: {
backgroundColor: '#008cc3',
height: 108,
width: 108,
padding: 10,
alignSelf: 'center',
justifyContent: 'center'
},
menuBtnContainer: {
height: 80,
width: 80,
alignSelf: 'center',
justifyContent: 'center'
},
});
Call in app.tsx file
<Sidemnu />
Whenever you want to display this side menu.
If you have any queries, please write back.

Error: Command fail: gradlew.bat app:installDebug -PreactNativeDevServerPort=8081.
Question: How can i fix the mistake? Because when i star a new file, it did not haave the mistake. Thank for your attention.

Horizontal scrollview inside another horizontalscroll view in react-native

I'm designing UI in react native where I've a HorizontalScrollView inside another HorizontalScrollView. However, the child HorizontalScrollView doesn't work.
Is it possible to disable the parent HorizontalScrollView whenever a gesture is made in child HorizontalScrollView. I know this sounds tricky but I need to implement this in my UI.
note: working fine in IOS
code snippet:
import React from 'react';
import { StyleSheet, Text, View, Dimensions, SafeAreaView, TouchableHighlight, ScrollView,
TouchableOpacity, TouchableWithoutFeedback, Image, Linking, Platform } from 'react-native';
import Carousel, { Pagination } from 'react-native-snap-carousel';
import { Input, Button, Divider, Card, Overlay } from 'react-native-elements';
export default class Cart extends React.Component {
state = {
data: [
{ title: 'a', url: require("./Light-Hover34x34.png") },
{ title: 'b', url: require("./Light-Hover34x34.png") },
{ title: 'c', url: require("./Light-Hover34x34.png") },
{ title: 'd', url: require("./Light-Hover34x34.png") },
{ title: 'e', url: require("./Light-Hover34x34.png") },
],
activeSlide: 0,
room: ["one", "two", "three"]
}
_renderItem = ({ item, index }) => {
console.log("active slide", this.state.activeSlide)
const isActive = index === this.state.activeSlide;
return (
<TouchableHighlight
// onPress={() => Linking.openURL(item.url)}
style={{
backgroundColor: isActive ? '#FFD845' : null,
width: 60,
height: 60,
borderRadius: 60/2,
justifyContent: 'center',
alignItems: 'center',
}}>
<Image
source={item.url}
style={{ width: '50%', height: '40%' }}
/>
</TouchableHighlight>
);
};
render() {
return (
<View style={{alignItems: 'center', justifyContent: 'center', paddingVertical: 100}}>
<ScrollView horizontal={true}>
{
this.state.room.map((r, i) => {
return(
<View key={i}>
<TouchableWithoutFeedback>
<Card containerStyle={[styles.cardEleBig,]}>
<SafeAreaView style={{ height: 150 }}>
<Carousel
data={this.state.data}
renderItem={this._renderItem}
sliderWidth={120}
itemWidth={50}
onSnapToItem={index => this.setState({ activeSlide: index })} //for pagination
/>
</SafeAreaView>
</Card>
</TouchableWithoutFeedback>
</View>
)
})
}
</ScrollView>
</View>
);
}
}
const styles = StyleSheet.create({
cardCircleParking: {
backgroundColor: "yellow",
// marginBottom: 10,
// marginLeft: '5%',
width: 50,
height: 50,
borderRadius: 50/2,
borderColor: 'white',
},
cardEleBig: {
borderRadius: 20,
borderBottomWidth: 0,
borderColor: 'white',
width: 159,
height: Platform == "ios" ? 210 : 200,
shadowColor: "#000",
shadowOffset: {
width: 0,
height: 2,
},
shadowOpacity: 0.25,
shadowRadius: 3.84,
elevation: 5,
marginLeft: 5,
marginRight: 5,
marginTop: 10,
marginBottom: 2
},
})
But this code is working fine with IOS
Thanks in advance

React Native (android) , components overlapping with shadow issue

I am using a custom component with image and text. The image is relative to the text. Please see the screenshot.
image 1
image 2.
I have used the TouchableOpacity component as root view for that.
In screenshots when long press on the component, two views are overlapping with shadow. It looks ugly when long press.
Please see the code below for reusable component.
'use strict';
import React, {Component} from 'react';
import {
StyleSheet,
Text,
View,
TouchableOpacity,
Image,
} from 'react-native';
export default class ExampleButton extends Component {
constructor (props) {
super (props);
}
_handleOnPress = () => {
console.log('pressed!!!');
};
render () {
console.log (this.props);
return (
<TouchableOpacity
onPress={this.handleOnPress}
>
<View style={styles.btnCompContainer}>
<View
style={{
backgroundColor: '#FFF',
justifyContent: 'center',
borderRadius: 30,
height: 50,
width: '100%',
}}
>
<Text style={styles.btnTxt}>{this.props.buttonText}</Text>
</View>
<View style={[styles.btnElmContainer]}>
<Image
style={[{height: 30, width: 30,resizeMode:'stretch'}]}
source={this.props.image}
/>
</View>
</View>
</TouchableOpacity>
);
}
}
const styles = StyleSheet.create ({
btnCompContainer: {
flexDirection: 'row',
alignItems: 'center',
height: 60,
marginLeft: 10,
marginRight: 20,
},
btnElmContainer: {
position: 'absolute',
justifyContent: 'center',
alignItems: 'center',
width: 60,
height: 60,
backgroundColor:'#fff',
borderRadius: 30,
shadowColor: '#000000',
shadowOffset: {
width: 1,
height: 1,
},
elevation:5,
shadowRadius: 2,
shadowOpacity: 0.3,
},
btnTxt: {
marginLeft: 80,
color: '#9e9e9e',
fontSize: 16,
fontWeight: 'bold',
textAlign: 'left',
},
});
Here I am using this reusable component in code.
'use strict';
import React, {Component} from 'react';
import {
Animated,
StyleSheet,
Text,
TextInput,
View,
Image,
ImageBackground,
TouchableOpacity,
Button,
StatusBar,
Easing
} from 'react-native';
// Custom Components
const searchBGImg = require('../assets/search-bg-kit.png');
const houseLogo = require('../Resources/house.png');
import ExampleButton from './components/common/example-button';
export default class TypeSelect extends Component<Props> {
// Navigation Option
static navigationOptions = {
header: null
}
constructor() {
super();
this.state = {
visible: false,
x: new Animated.Value(-100),
};
}
slide = () => {
Animated.spring(this.state.x, {
toValue: 0,
easing: Easing.easeOutBack
}).start();
this.setState({
visible: true,
});
};
gotoSearch = () =>{
this.props.navigation.navigate('DocSearch')
}
componentDidMount(){
this.slide();
}
render() {
return (
<View style={styles.container}>
<ImageBackground source={searchBGImg} style={styles.imgBG}>
<View style={{alignItems:'center', marginBottom:20}}>
<Image style={{height:57, width:69, marginBottom:12}} source={houseLogo} />
</View>
<View>
<Animated.View
style={[styles.slideView, {
transform: [
{
translateX: this.state.x
}
]
}]}>
<ExampleButton image={houseLogo} buttonText={'Click here'} />
<ExampleButton image={houseLogo} buttonText={'Click here'} />
</Animated.View>
</View>
</ImageBackground>
</View>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1
},
imgBG:{
flex: 1,
flexDirection: "column",
justifyContent:"center",
width: "100%",
height: "100%"
}
})
It is working fine in iOS, but it's not working in android up to the mark. Please help me to work it in android.
Thanks in advance.
You should use renderToHardwareTextureAndroid prop on <View /> component.
In your example like this:
<View style={styles.btnCompContainer} renderToHardwareTextureAndroid >
<View
style={{
backgroundColor: '#FFF',
justifyContent: 'center',
borderRadius: 30,
height: 50,
width: '100%',
}}
>
<Text style={styles.btnTxt}>{this.props.buttonText}</Text>
</View>
<View style={[styles.btnElmContainer]}>
<Image
style={[{height: 30, width: 30,resizeMode:'stretch'}]}
source={this.props.image}
/>
</View>
</View>

ScrollView not enabling scrolling in React Native App

Using Expo and the Android App, the <ScrollView> section is not scrolling. I've read through a lot of related questions but can't seem to nail down the issue. Can anyone shed some light for a react native newbie?
On pressing the button the API is requested and then the article headlines are rendered. This all works great but the headlines are not scrollable and don't all fit on the screen. Am I misunderstanding what <ScrollView> does?
import React from 'react'
import { ScrollView, StyleSheet, Text, View, Footer } from 'react-native'
import { Font } from 'expo'
import { Button } from 'react-native-elements'
export default class App extends React.Component {
state = {
fontLoaded: true,
buttonPressed: false,
showButton: true
}
onPress = (e) => {
e.preventDefault()
this.fetchArticlesAsync()
this.setState({
buttonPressed: true,
showButton: false
})
}
async fetchArticlesAsync() {
await fetch('http://content.guardianapis.com/search?show-fields=all&api-key=d8d8c012-6484-4bb4-82d7-2770a7c5d029')
.then(response => response.json())
.then(responseJSON => {
return this.setState({
articleList: responseJSON.response.results
})
})
.catch((error) => {
console.log(error)
})
}
render() {
return (
<ScrollView contentContainerStyle={styles.container}>
{
this.state.fontLoaded &&
<View style={this.state.buttonPressed ? styles.newsContainer : styles.container}>
<Text style={styles.header}>Newsli</Text>
{this.state.showButton &&
<Button buttonStyle={styles.button} onPress={this.onPress} clear text='Feed Me' />}
{this.state.buttonPressed &&
<View>
{this.state.articleList ?
<View style={styles.articleContainer}>
{this.state.articleList.map((article, i) => {
return <View style={styles.articleContainer} key={i}>
<Text style={styles.text}>{article.webTitle}</Text>
</View>
})}
</View> : <Text style={styles.loading}>Loading</Text>}
</View>}
</View>
}
</ScrollView>
)
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: '#000',
alignItems: 'center',
justifyContent: 'center',
},
newsContainer: {
flex: 1,
backgroundColor: '#000',
alignItems: 'center',
justifyContent: 'flex-start',
marginTop: 15
},
articleContainer: {
flex: 1,
backgroundColor: '#000',
alignItems: 'flex-start',
justifyContent: 'flex-start',
marginTop: 15
},
header: {
fontSize: 90,
color: '#fff'
},
text: {
fontSize: 20,
color: '#fff',
},
loading: {
fontSize: 24,
color: '#FF69B4'
},
button: {
borderColor: '#fff',
borderWidth: 2
}
})
It was quite small mistake. The ScrollView does not know current device's screen size. You need to have ScrollView inside a View component. Try the following...
<View style={styles.container}>
<ScrollView>
{...}
</ScrollView>
</View>
Next time when you submit a question strip out all nonsense code. Like Font fetching.
Good luck!
