how to dynamically control the indicatorStyle react navigation 5x - javascript

I have 4 screens, then I used the Style indicator to get a white border. However my border on the outros screen is too big and the restaurantes screen is small. How can I put a different width of the Style indicator for each screen? I'm using react navigation 5x Look how it is https://i.stack.imgur.com/9D5UW.png
https://i.stack.imgur.com/eVgHi.png
My code
import React from 'react';
import { createMaterialTopTabNavigator } from '#react-navigation/material-top-tabs';
import Restaurantes from '../pages/Restaurantes';
import Mercados from '../pages/Mercados';
import Farmácias from '../pages/Farmácias';
import Outros from '../pages/Outros';
const Tab = createMaterialTopTabNavigator();
export default function Routes() {
return (
<>
<Tab.Navigator
tabBarOptions={{
allowFontScaling: false,
activeTintColor: '#111',
inactiveTintColor: '#a8a8a8',
indicatorStyle: {
height: 23,
width: 80,
position: 'absolute',
left: '3%',
marginBottom: 12,
borderRadius: 15,
marginLeft: 5,
backgroundColor: '#fff',
},
tabStyle: {
marginLeft: 10,
paddingLeft: 20,
},
labelStyle: {
fontSize: 12,
width: 100,
},
style: {
backgroundColor: '#5f12b8',
},
}}
>
<Tab.Screen name="restaurantes" component={Restaurantes} />
<Tab.Screen name="mercados" component={Mercados} />
<Tab.Screen name="farmácias" component={Farmácias} />
<Tab.Screen name="outros" component={Outros} />
</Tab.Navigator>
</>
);
}

You can use 'renderIndicator'.
I will give you an example.
Copy paste the below code inside your 'tabBarOptions'
renderIndicator: (route) => {
if (!route.getTabWidth()) {
return null;
}
return (
<View style={{
width: route.getTabWidth(),
height: '100%',
left: route.navigationState.index * route.getTabWidth(),
backgroundColor: 'orange',
alignItems: 'center',
justifyContent: 'center',
}}>
<View style={{
position: 'absolute',
width: '80%',
backgroundColor: '#fff',
borderRadius: 15,
height: 20,
}}></View>
</View>
)},
}}
This should fix your issue. Some simple tweaking is necessary. If you need more help. Please do ask.
I will link the docs for you as well.

Progress bar UI custom design in React Native

I'm quite new to react native and javascript and I have to make this type of progress bar with the four categories.
Can anyone help or suggest to me how can I achieve this UI in react native for android and iOS on both platforms?
The expected output screenshot is attached below:
However, I don't need the user interaction or progress animation, I just have to show the fix progress in percentage.
Here's an approximation of your component built in React Native, you'll need to add react-native-linear-gradient to your dependencies beforehand
I have also created a demo on Expo (you should test it on the target device) that uses expo's version of the linear gradient library. https://snack.expo.dev/#sabihi/milestone-progressbar
import * as React from 'react';
import { Text, View, StyleSheet } from 'react-native';
import LinearGradient from 'react-native-linear-gradient';
export default function App() {
return (
<View style={styles.container}>
<View style={styles.progressLabels}>
<Text style={styles.progressLabel}>Beginner</Text>
<View style={styles.progressLabel}></View>
<Text style={styles.progressLabel}>Amateur</Text>
<View style={styles.progressLabel}></View>
<Text style={styles.progressLabel}>Elite</Text>
<View style={styles.progressLabel}></View>
<Text style={styles.progressLabel}>Master</Text>
</View>
<View style={styles.progressContainer}>
<LinearGradient colors={["rgb(7, 14, 60)", "rgb(86, 90, 106)"]} style={styles.progress}/>
<View style={styles.milestonesContainer}>
<View style={styles.milestone}/><View style={styles.milestone}/><View style={styles.milestone}/>
</View>
</View>
</View>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
// paddingTop: Constants.statusBarHeight,
backgroundColor: '#ecf0f1',
padding: 8,
},
progressLabels: {
display: "flex",
flexDirection: "row",
justifyContent: "space-between",
width: "100%",
marginBottom: 10,
},
progressLabel: {
fontSize: 12,
fontWeight: 'bold',
fontFamily: "sans-serif",
width: "14.3%",
textAlign: "center"
},
progressContainer: {
position: "relative",
height: 100
},
progress: {
marginLeft: "5%",
marginTop: 5,
width: "90%",
height: 30,
// backgroundColor: "rgb(7, 14, 60)",
borderRadius: 15
},
milestonesContainer: {
marginLeft: "5%",
position: "absolute",
width: "100%",
display: "flex",
flexDirection: "row"
},
milestone: {
height: 40,

borderRightWidth: 1,
}

React Native ScrollView Horizontal not working

I'm new to react native, and I'm trying to put a horizontal scrollview on my screen.
I've tried to put <ScrollView horizontal={true}> but it's not working at all, I want the blue box scrollable.
here' the image of my screen :
and this for my component code :
import React from 'react';
import {View, StyleSheet, Text, Image, ScrollView} from 'react-native';
export default function Body() {
return (
<View>
<View style={styles.jadwal}>
<ScrollView horizontal={true}>
<View style={styles.box}>
<Text style={styles.title}>Math</Text>
<View style={styles.wrap}>
<View style={styles.alert}>
<Text style={styles.pr}>3 Homework</Text>
<Image
style={styles.img}
source={require('../assets/math.png')}
/>
</View>
</View>
</View>
<View style={styles.box}>
<Text style={styles.title}>Biology</Text>
<View style={styles.wrap}>
<View style={styles.alert}>
<Text style={styles.pr}>10 Homework</Text>
<Image
style={styles.img}
source={require('../assets/math.png')}
/>
</View>
</View>
</View>
</ScrollView>
</View>
</View>
);
}
const styles = StyleSheet.create({
jadwal: {
marginLeft: 10,
flexDirection: 'row',
justifyContent: 'flex-start',
position: 'absolute',
},
box: {
height: 100,
width: 230,
borderRadius: 10,
backgroundColor: '#327fe3',
marginLeft: 10,
},
alert: {
height: 20,
marginLeft: 15,
width: 80,
borderRadius: 10,
backgroundColor: '#7CD5FF',
},
title: {
marginTop: 20,
marginLeft: 20,
fontFamily: 'MontserratSemiBold',
fontSize: 15,
color: '#fff',
},
pr: {
marginLeft: 14,
fontSize: 8,
color: '#fff',
marginTop: 4,
justifyContent: 'flex-start',
fontFamily: 'MontserratLight',
},
wrap: {
marginTop: 5,
},
img: {
height: 50,
width: 50,
marginLeft: 140,
marginTop: -35,
},
});
is there anything wrong ?, did I put the <ScrollView> on wrong position ?
Thanks for reading this, and sorry for my bad english.
There's one error of font-family cause, this font is not installed in my laptop.
Overall your scroll view is working fine.
Note: scroll view is scrolling area is in between the opening and closing tag of scroll.

create a curved bottom navigation (before after implementation)

How can I achieve this in react native?
So far I have this and I want to implement the middle curve. I don't know to either handle it with a transparent view or switch to SVG completely
and this the tabBar component

i hope this will help you.
Here is 2 solution according to your requirement.
If you want this type of design without selection then this code will help you :
https://github.com/alex-melnyk/clipped-tabbar
And if you need on each tab selection then here is other easy library for you :
https://github.com/Jm-Zion/rn-wave-bottom-bar
It's not obvious that this can be done with only <View/> components. I would split the TabBar into a flex row container with three subviews, and create an SVG with the filled inverted radius to be used in the center subview. To render the SVG, use react-native-svg. See a rough layout below:
...
import { SvgXml } from 'react-native-svg';
import TabCenterSvg from ‘assets/my-svg.svg’
export default class TabBar extends Component {
render() {
return (
<View style={styles.tabBar}>
<View style={styles.leftContainer}>
{/* Left Buttons */}
</View>
<View style={styles.centerContainer}>
<View style={styles.centerInnerTopContainer}>
{/* Add Button */}
</View>
<View style={styles.centerInnerBottomContainer}>
<SvgXml xml={TabCenterSvg} />
</View>
</View>
<View style={styles.rightContainer}>
{/* Right Icons */}
</View>
</View>
)
}
}
const styles = StyleSheet.create({
tabBar: {
alignSelf: 'center',
borderRadius: 50,
bottom: 10,
elevation: 2,
flexDirection: 'row',
height: 65,
position: 'absolute',
width: '95%',
},
leftContainer: {
flex: 1,
flexDirection: 'row',
borderBottomLeftRadius: 50,
borderTopLeftRadius: 50,
borderTopRightRadius: 50,
backgroundColor: Colors.primary,
},
centerContainer: {
flex: 1,
flexDirection: 'column',
},
centerInnerTopContainer: {
flex: 1,
},
centerInnerBottomContainer: {
flex: 1,
},
rightContainer: {
flex: 1,
flexDirection: 'row',
borderTopLeftRadius: 50,
borderTopRightRadius: 50,
borderBottomRightRadius: 50,
backgroundColor: Colors.primary,
},
})
Use this library's code and customize according to your UI
https://www.npmjs.com/package/curved-bottom-navigation-bar
Note: I'll not recommend this library as there are low weekly downloads.
Rather than using the whole library, you can use its code.

Make Search using firebase in react native

I am new to react native and firebase. I want to make a search bar that can search all data from firebase according to Barcode value, but I'm facing some errors while doing it. I think that my code is wrong somewhere but don't know where. I have transferred the firebase credentials to dbConfig.js . Here is my firebase data firebase data and my code:
import React,{Component} from 'react';
import { View, Text,TextInput,StyleSheet,Image, Button} from 'react-native';
import firebase from './dbConfig';
export default class ListItem extends Component {
render() {
return (
<>
<View style={styles.BackGround}>
<View style={styles.SectionStyle}>
<Image
source={require('./mic.png')} //mic image here
style={styles.ImageStyle}
/>
<TextInput
style={{ flex: 1, justifyContent: 'center', textAlign: 'center', fontSize: 12}}
placeholder="Search for Product"
underlineColorAndroid="transparent"
//onChangeText={(text) => this.setState({data: text})}
onSubmitEditing = {(text)=> this.setState({data: text})}
value = {this.state.data}
// onSubmitEditing={()=>this._search}
//onSubmitEditing={()=>this.componentWillMount}
/>
<Image
source={require('./usr.png')} //icon image here
style={styles.ImageStyle2}
/>
</View>
<View>
<Text>{this.state.items}</Text>
</View>
</View>
</>
);
}
constructor(props){
super(props);
this.state= {
items: '',
data: '',
};
}
componentWillMount(){
var ref = firebase.database().ref('/');
ref.child(this.state.data).on("value", snapshot =>{
console.log(snapshot.val().info.Price);
//if(snapshot.val().Price == this.state.data){
//this.setState({items: Object.values(snapshot.val())});
//}
//else{
//alert('there is problem');
//}
});
}
}
const styles = StyleSheet.create({
BackGround: {
backgroundColor: '#22abb6',
height: '100%'
},
SectionStyle: {
flexDirection: 'row',
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#fff',
// borderWidth: 0.8,
// borderColor: '#000',
shadowColor:'#176f75',
marginTop: 50,
height: 40,
borderRadius: 10,
margin: 10,
},
ImageStyle: {
padding: 10,
marginLeft: 10,
margin: 5,
height: 25,
width: 25,
resizeMode: 'stretch',
alignItems: 'center',
},
ImageStyle2: {

marginLeft: 10,
marginRight: 10,
margin: 5,
height: 25,
width: 25,
resizeMode: 'stretch',
alignItems: 'center',

});
I did it by changing the follows:
//adding this in TextInput
onSubmitEditing = {this.componentWillMount}
//on changing the function compoundWillMount to async()
componentWillMount= async()=>{

How to slide <View/> in and out from the bottom in React Native?

In React Native iOS, I would like to slide in and out of a like in the following picture.
In the following example, when a button is pressed, the Payment Information view pops up from the bottom, and when the collapse button is pressed, it goes back down and disappears.
What would be the correct and proper way to go about doing so?
Thank you in advance!
EDIT
Basically, you need to absolute-position your view to the bottom of the screen. Then you translate its y value to equal its height. (The sub view must have a specific height in order to know how much to move it)
Code:
'use strict';
import React, {Component} from 'react';
import ReactNative from 'react-native';
const {
AppRegistry,
StyleSheet,
Text,
View,
TouchableHighlight,
Animated
} = ReactNative;
var isHidden = true;
class AppContainer extends Component {
constructor(props) {
super(props);
this.state = {
bounceValue: new Animated.Value(100), //This is the initial position of the subview
buttonText: "Show Subview"
};
}
_toggleSubview() {
this.setState({
buttonText: !isHidden ? "Show Subview" : "Hide Subview"
});
var toValue = 100;
if(isHidden) {
toValue = 0;
}
//This will animate the transalteY of the subview between 0 & 100 depending on its current state
//100 comes from the style below, which is the height of the subview.
Animated.spring(
this.state.bounceValue,
{
toValue: toValue,
velocity: 3,
tension: 2,
friction: 8,
}
).start();
isHidden = !isHidden;
}
render() {
return (
<View style={styles.container}>
<TouchableHighlight style={styles.button} onPress={()=> {this._toggleSubview()}}>
<Text style={styles.buttonText}>{this.state.buttonText}</Text>
</TouchableHighlight>
<Animated.View
style={[styles.subView,
{transform: [{translateY: this.state.bounceValue}]}]}
>
<Text>This is a sub view</Text>
</Animated.View>
</View>
);
}
}
var styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#F5FCFF',
marginTop: 66
},
button: {
padding: 8,
},
buttonText: {
fontSize: 17,
color: "#007AFF"
},
subView: {
position: "absolute",
bottom: 0,
left: 0,
right: 0,
backgroundColor: "#FFFFFF",
height: 100,
}
});
AppRegistry.registerComponent('AppContainer', () => AppContainer);
I know it is a little bit late, but thought it might be useful for someone. You should try out a component called rn-sliding-out-panel. It works awesomely. https://github.com/octopitus/rn-sliding-up-panel
<SlidingUpPanel
draggableRange={top: 1000, bottom: 0}
showBackdrop={true|false /*For making it modal-like*/}
ref={c => this._panel = c}
visible={ture|false /*If you want it to be visible on load*/}
></SlidingUpPanel>
And you can even open it from an external button:
<Button onPress={()=>{this._panel.transitionTo(1000)}} title='Expand'></Button>
You can install it via npm: sudo npm install rn-sliding-out-panel --save on your react-native root directory.
I hope it helps someone :D
I've created a reusable BottomSheet component that accepts any content.
This is how it looks like:
Here's the code (in TypeScript) of the BottomSheet component:
import * as React from 'react'
import {
Animated,
Easing,
Pressable,
StyleSheet,
useWindowDimensions,
View,
} from 'react-native'
const DEFAULT_HEIGHT = 300
function useAnimatedBottom(show: boolean, height: number = DEFAULT_HEIGHT) {
const animatedValue = React.useRef(new Animated.Value(0))
const bottom = animatedValue.current.interpolate({
inputRange: [0, 1],
outputRange: [-height, 0],
})
React.useEffect(() => {
if (show) {
Animated.timing(animatedValue.current, {
toValue: 1,
duration: 350,
// Accelerate then decelerate - https://cubic-bezier.com/#.28,0,.63,1
easing: Easing.bezier(0.28, 0, 0.63, 1),
useNativeDriver: false, // 'bottom' is not supported by native animated module
}).start()
} else {
Animated.timing(animatedValue.current, {
toValue: 0,
duration: 250,
// Accelerate - https://easings.net/#easeInCubic
easing: Easing.cubic,
useNativeDriver: false,
}).start()
}
}, [show])
return bottom
}
interface Props {
children: React.ReactNode
show: boolean
height?: number
onOuterClick?: () => void
}
export function BottomSheet({
children,
show,
height = DEFAULT_HEIGHT,
onOuterClick,
}: Props) {
const { height: screenHeight } = useWindowDimensions()
const bottom = useAnimatedBottom(show, height)
return (
<>
{/* Outer semitransparent overlay - remove it if you don't want it */}
{show && (
<Pressable
onPress={onOuterClick}
style={[styles.outerOverlay, { height: screenHeight }]}
>
<View />
</Pressable>
)}
<Animated.View style={[styles.bottomSheet, { height, bottom }]}>
{children}
</Animated.View>
</>
)
}
const styles = StyleSheet.create({
outerOverlay: {
position: 'absolute',
width: '100%',
zIndex: 1,
backgroundColor: 'black',
opacity: 0.3,
},
bottomSheet: {
position: 'absolute',
width: '100%',
zIndex: 1,
// Here you can set a common style for all bottom sheets, or nothing if you
// want different designs
backgroundColor: 'dodgerblue',
borderRadius: 16,
},
})
I put this code in a file named BottomSheet.tsx.
This is how you use the BottomSheet:
import * as React from 'react'
import {
Pressable,
SafeAreaView,
StatusBar,
StyleSheet,
Text,
View,
} from 'react-native'
import { BottomSheet } from './src/BottomSheet'
const App = () => {
const [showBottomSheet, setShowBottomSheet] = React.useState(false)
const hide = () => {
setShowBottomSheet(false)
}
return (
<SafeAreaView style={styles.safeAreaView}>
<StatusBar barStyle={'dark-content'} />
<View style={styles.container}>
<Pressable
onPress={() => {
setShowBottomSheet(true)
}}
style={styles.showButton}
>
<Text style={styles.buttonText}>Show bottom sheet</Text>
</Pressable>
</View>
<BottomSheet show={showBottomSheet} height={290} onOuterClick={hide}>
<View style={styles.bottomSheetContent}>
<Text style={styles.bottomSheetText}>Hey boys, hey girls!</Text>
<Pressable onPress={hide} style={styles.bottomSheetCloseButton}>
<Text style={styles.buttonText}>X Close</Text>
</Pressable>
</View>
</BottomSheet>
</SafeAreaView>
)
}
const styles = StyleSheet.create({
safeAreaView: {
flex: 1,
},
container: {
flex: 1,
},
showButton: {
marginTop: 48,
padding: 16,
backgroundColor: 'mediumspringgreen',
alignSelf: 'center',
borderRadius: 8,
},
buttonText: {
fontSize: 20,
},
bottomSheetContent: {
padding: 40,
alignItems: 'center',
},
bottomSheetText: {
fontSize: 24,
marginBottom: 80,
},
bottomSheetCloseButton: {
padding: 16,
backgroundColor: 'deeppink',
borderRadius: 8,
},
})
export default App
Notes:
I've put an outer semitransparent overlay, but you can get rid of it by deleting it.
I've chosen to close the modal when you click on the outer semitransparent overlay. This is done with the onOuterClick callback, which is optional - don't pass it if you don't want to do anything.
I've put some styling (blue background + border radius) that applies to all bottom sheets, but you can remove it if you want to have different styles.
After a quite long search I found very good library called react-native-swipe-down with MIT licence.
It will help you make a slider <View /> with no effort.
I Hope this library help you out.
import SwipeUpDown from 'react-native-swipe-up-down';
<SwipeUpDown
itemMini={<ItemMini />} // Pass props component when collapsed

To achive above type of requirnment we can take help of some greate libraries
1 #gorhom/bottom-sheet
2 react-native-raw-bottom-sheet
But if we want to do with nativelly please find a code below, I'll try to justify the answer:)
For some animation effects I'll take reference from blow site
how-to-create-moving-animations-in-react-native
import React, { useState } from 'react'
import { SafeAreaView, View, ScrollView, Text, Dimensions, TouchableOpacity, Animated } from 'react-native'
const App = () => {
const { height, width } = Dimensions.get('window')
const SCREEN_HEIGHT = Math.round(height)
const SCREEN_WIDTH = Math.round(width)
// Animation
const startValue = new Animated.Value(Math.round(height + height * 0.3))
const endValue = Math.round(height - height * 0.3)
const duration = 1000
const _showBottomView = (key) => {
const toValue = key === 'HIDE' ? height : endValue
Animated.timing(startValue, {
toValue,
duration: duration,
useNativeDriver: true,
}).start()
}
