my task is to give space to this text which is supposed to appear in a straight line (Elon Musk
11:11AM) using justifyContent: 'space-between' but its not having any effect instead the text are still together (Elon Musk11:11AM)
<View style={styles.row}>
<Text style={styles.name}>Elon Musk</Text>
<Text style={styles.text}>11:11 AM</Text>
</View>
<Text style={styles.text}>Boi Ice for Janet</Text>

row:{

text:{

}
});
You would need to use a
row:{
flex:1
// other keys
}
and/or
row:{
width:'100%'
}
so that the view (row) covers the width of the screen.

I'm getting this weird error when I'm running my code on Expo Go on IOS
I'm new to react native and I don't know what to do
This is my code:
import React, { Component } from 'react';
import { Button, StyleSheet, Text, TextInput, View } from 'react-native';
export default class ButtonBasics extends Component {
_onPressButton() {
alert("Don't touch that button!")
}
render() {
return (
<View style={styles.container}>
<View style={styles.buttonContainer}>
<text>Press the button</text>
<Button title="Press" onPress={this._onPressButton} color="#57a9af" />
<View/>
</View>
</View>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: '#d6f0f2',
alignItems: 'center',
justifyContent: 'center',
},
});
Well There are multiple problems with your Code,
<text> is not a valid component. It is <Text> with Capital T. You have imported the right Component but using the wrong Tag.
You have three end tags. While you have only two start tags.
So your code should be
import React, { Component } from 'react';
import { Button, StyleSheet, Text, TextInput, View } from 'react-native';
export default class ButtonBasics extends Component {
_onPressButton() {
alert("Don't touch that button!")
}
render() {
return (
<View style={styles.container}>
<View style={styles.buttonContainer}>
<Text>Press the button</Text>
<Button title="Press" onPress={this._onPressButton} color="#57a9af" />
<View/>
</View>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: '#d6f0f2',
alignItems: 'center',
justifyContent: 'center',
},
});
My ImageBackground module is only showing a white background. The code shown is basically a boilerplate template from React's official documentation on ImageBackgrounds. My uri is not null. "props.route.params.image" is type TakePictureResponse from react-native-camera module.
I look at similar questions to this one, the solutions to theirs were already implemented in mine.
const styles = StyleSheet.create({
container: {
flex: 1,
flexDirection: 'column',
},
image: {
flex: 1,
resizeMode: 'cover',
justifyContent: 'center',
}
})
render() {
return (
<View style={styles.container}>
<ImageBackground
source={{uri: this.props.route.params.image.uri}}
style={styles.image}
/>
</View>
);
}
You should mention height and width for image Styling and wrap the content inside ImageBackground (just use ImageBackground like a View Component)
image: {
resizeMode: 'cover',
justifyContent: 'center',
width:'100%',
height:'100%'
}
// Example
// App.js
import React from 'react';
import { StyleSheet, Text, View, ImageBackground} from 'react-native';
export default function App() {
const imageUrl = 'https://images.pexels.com/photos/312418/pexels-photo-312418.jpeg?auto=compress&cs=tinysrgb&dpr=1&w=500'
return (
<View style={styles.container}>
<ImageBackground
source={{uri: imageUrl}}
style={styles.image}
>
<Text
style={{userSelect:'text',color: '#fff', fontWeight:'bold', fontSize:32, marginTop: 180}}>{'My Text Element'}</Text>
</ImageBackground>
</View>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
flexDirection: 'column',
},
image: {
resizeMode: 'cover',
justifyContent:'flex-start',
alignItems:'center',
width:'100%',
height:'100%'
}
})
output
make sure { backgroundColor: undefined } for the View components inside the ImageBackground
if {backgroundColor: '#fff'} then the white layer will cover the background image
<ImageBackground
source={{uri: imageUrl}}
style={styles.image}
>
<View style={{
// (eliminate 'white' layers)
backgroundColor: undefined,
width:'100%', height:'100%', alignItems:'center'}}>
<Text style={{ color: '#fff',fontWeight:'bold',
fontSize:32, marginTop: 180}}> {'My Text Element'}
</Text>
</View>
</ImageBackground>
I am trying to detect touch on a view in React Native. I followed this link and incorporated the Touchable around my styled view like so:
<TouchableWithoutFeedback onPress={cardPressed}>
<View style={styles.card}>
<Text style={styles.card_Head}>What is Something?</Text>
<Text style={styles.card_Body}>Something</Text>
</View>
</TouchableWithoutFeedback>
I am using a functional component, so after export default function App() { I have:
function cardPressed()
{
console.log('pressed');
}
No errors, but I get nothing. What is wrong w this implementation?
Check your import. You should import TouchableWithoutFeedback from react-native and not from react-native-gesture-handler
Check out this code.
import React, { useState } from "react";
import { StyleSheet, TouchableWithoutFeedback, Text, View } from "react-native";
const App = () => {
const [count, setCount] = useState(0);
const cardPressed = () => {
console.log('pressed');
setCount(count + 1);
};
return (
<View style={styles.container}>
<View style={styles.countContainer}>
<Text style={styles.countText}>Count: {count}</Text>
</View>
<TouchableWithoutFeedback onPress={cardPressed}>
<View style={styles.button}>
<Text style={styles.card_Head}>What is Something?</Text>
<Text style={styles.card_Body}>Something</Text>
</View>
</TouchableWithoutFeedback>
</View>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: "center",
paddingHorizontal: 10
},
button: {
alignItems: "center",
backgroundColor: "#DDDDDD",
padding: 10
},
countContainer: {
alignItems: "center",
padding: 10
},
countText: {
color: "#FF00FF"
},
card_Head: {
fontWeight: 'bold',
fontSize: 24
},
card_Body: {
fontStyle: 'italic'
}
});
export default App;
I face a little problem while styling for Iphone X, I used widthPercentageToDP and heightPercentageToDP from react-native-responsive-screen to make the view similar, in most of the devices it worked perfectly except Iphone X, the difference is a little bit but I want to make the view accurate as possible.
<View style={styles.container}>
<ImageBackground source={require('../../assets/acc.png')} style={styles.bgImg}>
<View style={styles.headerView}>
<FontAwesome style={styles.setting} name="cog" size={hp('4%')} color="#6B6466" />
<Text style={styles.headerText}>My Account</Text>
</View >
<View style={styles.imgView} >
<Image source={require('../../assets/user.png')} style={styles.accImg}/>
<Text style={styles.name}> John doe</Text>
<Text style={styles.number}> 123456789</Text>
</View>
<View style={styles.bottomView}>
<View style={styles.bottomView2}>
<TouchableOpacity style={styles.inboxView}>
<Text style={styles.inboxNumber}>12</Text>
<Text style={styles.inboxText}>Inbox</Text>
</TouchableOpacity>
<TouchableOpacity style={styles.inboxView}>
<Text style={styles.inboxNumber}>17</Text>
<Text style={styles.inboxText}>Sent</Text>
</TouchableOpacity>
</View>
</View>
</ImageBackground>
</View>
Style
const styles = StyleSheet.create({
container: {
flex: 1, backgroundColor: '#fff'
},
bgImg:{
height: hp('40%'), width: '100%'
},
setting:{
color:'white'
},
headerText:{
flex:1,textAlign:'center',fontSize:wp('5%'),fontFamily:Fonts.Cairo,marginRight:10,color:'white'
},
headerView:{
flexDirection:'row',justifyContent:'space-between',marginHorizontal:10,marginTop:hp('5%')
},
imgView:{
flex:1,
alignItems:'center'
},
accImg:{
height:wp('30%'),width:wp('30%'),borderRadius:wp('15%'),marginTop:wp('3%')
},
name:{
color:'white',fontFamily:Fonts.Cairo,fontSize:wp('4%'),textAlign:'center'
},
number:{
color:'white',fontSize:wp('4%'),textAlign:'center'
},
bottomView:{
flex:1,
justifyContent:'flex-end'
},
inboxNumber:{
color:'white',
textAlign:'center',
fontSize:wp('4%')
},
inboxText:{
color:'white',
textAlign:'center',
fontSize:wp('4%'),
fontFamily:Fonts.Cairo
},
bottomView2:{
flexDirection:'row',
justifyContent:'space-between',
marginHorizontal:10,
marginBottom:wp('3%')
},
});

The Iphone X is rendering the real result, this is how your layout looks like, the other devices don't have enought space for rendering and they "overlap" the views ... Look at your views, you have an imagebackground wich takes 40% of the screen , inside you have a header wich will render normally since it's higher in the render function.
Below you have a view with flex :1 and inside an image with screen based values with 2 rows of text below , if the image is lager than the view it will push the text outside of the view , invading the below neighbour view
BELOW that you have a view with the 2 touchableopacitys . they should not be overlapping. In fact, try adding overflow:'hidden' to the imgView style
------header------
///////IMAGE////////
///////IMAGE////////
///////Johndo///////
///////12345////////
Button//////Button
Just like the iphone is showing
<ImageBackground source={require('../../assets/acc.png')} style={styles.bgImg}>
<View style={styles.headerView}>
//here is the header
</View >
<View style={styles.imgView} >
// below is the image , the name , and the number
</View>
<View style={styles.bottomView}>
//below it should be the 2 buttons , not overlapping, BELOW
</View>
</ImageBackground>
I'm building an iOS app with React Native and am implementing a TabBarIOS. The content on the tabs seems to flow behind and be obscured by the bar. In xcode I would have just unchecked the "extend edges" boxes but am not sure how to do this with React Native.
Here's an abbreviated version of what I'm trying to do. The <View> from CreateUser flows behind the tab bar. Is there an easy way to make sure content doesn't get obscured by the tab bar?
import React from 'react'
import {
StyleSheet,
Text,
TextInput,
View,
TouchableHighlight,
} from 'react-native'
export default class TabBar extends React.Component {
state = {
selectedTab: 'list'
}
render() {
return (
<TabBarIOS selectedTab={this.state.selectedTab}
unselectedTintColor="#ffffff"
tintColor="#ffe429"
barTintColor="#294163">
<TabBarIOS.Item
title="My List"
systemIcon="bookmarks"
selected={this.state.selectedTab==='list'}
onPress={() => {
this.setState({
selectedTab: 'list',
});
}}
>
<CreateUser />
</TabBarIOS.Item>
</TabBarIOS>
);
}
}
var styles = StyleSheet.create({
tabContent: {
flex: 1,
alignItems: 'center',
},
tabText: {
color: 'darkslategrey',
margin: 50,
},
});
export default class CreateUser extends React.Component{
render(){
return (
<View style={styles.container}>
<TouchableHighlight style={styles.button}>
<Text style={styles.buttonText}>LOG IN</Text>
</TouchableHighlight>
</View>
)
}
}
var styles = StyleSheet.create({
container: {
flex: 1,
flexDirection: "column",
justifyContent: "flex-end",
alignItems: 'center',
},
button: {
backgroundColor: "#ffe429",
borderRadius: 3,
height: 60,
width: 200,
margin: 7,
//flex: 1,
alignItems: "center",
justifyContent: "center",
},
buttonText: {
color: "#294163",
}
})
This was a problem for me when using a NavigatorIOS component that then rendered it's initialRoute component which contained a TabBarIOS component.
If this is the case for your scenario, you can fix it by using a ScrollView:
Add the flex layout style to your NavigatorIOS:
<NavigatorIOS
initialRoute={{
component: MyView,
title: 'My View',
}}
style={{flex: 1}}
/>
Use a ScrollView:
<TabBarIOS>
<TabBarIOS.Item
systemIcon="history"
title="A Tab">
<ScrollView>
<Text>
Hello World
</Text>
</ScrollView>
</TabBarIOS.Item>
</TabBarIOS>
In my case I needed to add flex: 1 to the style props for the top-level View of the screen.
RN Navigation docs
//MyScreen.tsx
export default () => (
<View style={{ flex: 1 }}>
...
</View>
)
