I have this React Native proyect (with Expo), and i have 2 buttons on the bottom of the container. When i open the keyboard to write something, those items come up with the keyboard. ¿How can i avoid that?
Here's the container code ->
render() {
return (
<View style={{flex: 1}}>
<Text style={styles.titulo}>Nueva Tarjeta</Text>
<View style={{ flex: 1}}>
<CreditCardInput
requiresName={true}
allowScroll={true}
labels={{
name: "Nombre del titular",
number: "Número de tarjeta",
expiry: "Venc",
cvc: "CVC",
}}
cardScale={1}
labelStyle={{ fontFamily: "OpenSansRegular" }}
placeholders={{
name: "Juan Perez",
number: "1234 1234 1234 1234",
expiry: "MM/AA",
cvc: "123",
}}
onChange={this._onChange}
/>
</View>
<View style={{ flexDirection: "row", alignSelf: "center",
justifyContent: 'flex-end', marginBottom: 10}}>
<TouchableOpacity style={styles.botonVolver}>
<Text style={styles.textoVolver}>Volver</Text>
</TouchableOpacity>
<TouchableOpacity style={styles.botonAceptar}>
<Text style={styles.textoAceptar}>Aceptar</Text>
</TouchableOpacity>
</View>
</View>
);
}
Thanks in advance!
You could try using a KeyboardAvoidingView with its behavior prop set to 'height' on Android:
const screenHeight = Dimensions.get("window").height;
export default function App() {
return (
<KeyboardAvoidingView behavior="height" style={{ flex: 1 }}>
<View style={{ height: screenHeight - 75 }}>
<Text style={styles.titulo}>Nueva Tarjeta</Text>
<CreditCardInput
requiresName={true}
allowScroll={true}
labels={{
name: "Nombre del titular",
number: "Número de tarjeta",
expiry: "Venc",
cvc: "CVC",
}}
cardScale={1}
labelStyle={{ fontFamily: "OpenSansRegular" }}
placeholders={{
name: "Juan Perez",
number: "1234 1234 1234 1234",
expiry: "MM/AA",
cvc: "123",
}}
/>
</View>
<View
style={{
flexDirection: "row",
alignSelf: "center",
justifyContent: "flex-end",
marginBottom: 10,
}}
>
<TouchableOpacity style={styles.botonVolver}>
<Text style={styles.textoVolver}>Volver</Text>
</TouchableOpacity>
<TouchableOpacity style={styles.botonAceptar}>
<Text style={styles.textoAceptar}>Aceptar</Text>
</TouchableOpacity>
</View>
</KeyboardAvoidingView>
);
}
I also changed the height of the View that contains the CreditCardInput to be based on the screen height using Dimensions, because the transition was glitchy when flex was set on that View.
Be sure to import Dimensions and KeyboardAvoidingView from 'react-native'.
I have problem with styling of the Text, I have two lines of the Text, the first line of the text appears correct on the center of the row, but second line of the code, is not in the center. How to fix that?
<View style={{ flex: 1, justifyContent: 'center', alignItems: 'center', flexDirection: 'row' }}>
<Text
style={{ marginLeft: 5, fontWeight: '500', fontFamily: 'Arial', fontSize: ratio * 14, color: '#3c3c3c' }}
numberOfLines={2} > {title}
</Text>
</View>
You need to use textAlign:'center',
<View
style={{
flex: 1,
justifyContent: "center",
alignItems: "center",
flexDirection: "row"
}}
>
<Text
style={{
textAlign:'center', //Added
marginLeft: 5,
fontWeight: "500",
fontFamily: "Arial",
fontSize: ratio * 14,
color: "#3c3c3c"
}}
numberOfLines={2}
>
{title}
</Text>
</View>
You just need to add textAlign in Text component
style={{textAlign: 'center', marginLeft: 5, fontWeight:'500',fontFamily: 'Arial', fontSize: ratio * 14, color:'#3c3c3c'}}
numberOfLines={2} >
Check snack demo here : https://snack.expo.io/SJyEEwM3b
import React, { Component } from 'react';
import { Text, View } from 'react-native';
export default class App extends Component {
render() {
return (
<View style={{ flex: 1, justifyContent: 'center', alignItems: 'center', flexDirection: 'row' }}>
<Text
style={{ textAlign: 'center', marginLeft: 5, fontWeight: '500', fontFamily: 'Arial', fontSize: 1 * 14, color: '#3c3c3c' }}
numberOfLines={2} > some text some text some text some text some text some text some text some text
</Text>
</View>
);
}
}
I am trying to make this highlighted line to stretch full width. I have tried many possible ways to come around it but could not get it as desired.
Here is my code from render() method.
return (
<ScrollView style={{backgroundColor: 'rgba(255,255,255,1)'}}>
<View style={styles.container}>
<Image style={styles.image} source={{uri: imageURI}} />
<View style={styles.content}>
<Text style={styles.title}>{news.title}</Text>
<View style={styles.itemIcons}>
<View style={styles.companyView}>
<Image
source={{uri: news.category[0].sourceImage}}
style={ styles.iconsImage} />
<Text style={styles.iconsText}>{news.category_name}</Text>
</View>
<Text style={styles.iconsTextRight}>{this.formatDate(news.pubDate)}</Text>
</View>
<Text style={styles.description}>{description}</Text>
</View>
</View>
</ScrollView>
);
And here are my styles for this.
container: {
flex: 1,
alignItems: 'center',
},
content: {
flex: 1,
flexDirection: 'column',
padding: 10
},
image: {
width: width,
height: custom_height,
// padding: 10
},
title: {
marginBottom: 15
},
itemIcons: {
flex: 1,
flexDirection: 'row',
alignSelf: 'stretch',
marginBottom: 15
},
iconsImage: {
height: 25,
width: 30,
marginRight: 10,
},
iconsText: {
fontSize: 12,
color: "#686666",
alignSelf: 'flex-end'
},
companyView: {flex:1,flexDirection:'row'},
dateView: {flex:1,alignSelf: 'flex-end'},
iconsTextRight: {
fontSize: 12,
color: "#686666",
alignSelf: 'flex-end'
},
description: {
padding: 2,
fontSize: 12,
color: '#323'
}
Change container style to
container: {
flex: 1,
}
Then the view will be aligned as per your requirement.
try this in itemIcons class
justify-content:'space-between'
I couldn't work with whole of your code, but as per the screenshot you posted, I was able to achieve this.
<View style={{flex:1}}>
<View style={{flexDirection:'row',paddingTop:100,justifyContent:'space-between',alignItems:'center'}}>
<View style={{flexDirection:'row',alignItems:'center'}}>
<Image source={require('./images/tiger.jpg')} style={{width:40,height:40}} />
<Text>Roche</Text>
</View>
<Text>25 Mar 2016, 18:16</Text>
</View>
</View>
Try to replicate this in your code and see if it works.
I have already read several flexbox tutorial, but I still cannot make this simple task to work.
How can I make the red box to 100% width?
Code:
<View style={styles.container}>
<Text style={styles.welcome}>
Welcome to React Natives
</Text>
<Text style={styles.line1}>
line1
</Text>
<Text style={styles.instructions}>
Press Cmd+R to reload,{'\n'}
Cmd+D or shake for dev menu
</Text>
</View>
style:
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#F5FCFF',
borderWidth: 1,
flexDirection: 'column',
},
welcome: {
fontSize: 20,
textAlign: 'center',
margin: 10,
borderWidth: 1,
},
line1: {
backgroundColor: '#FDD7E4',
},
instructions: {
textAlign: 'center',
color: '#333333',
marginBottom: 5,
borderWidth: 1,
},
Thank you!
Update 1:
Suggestion by Nishanth Shankar, adding
flex:1 for the wrapper,
flexDirection: 'row'
Output:
Code:
<View style={styles.container}>
<View style={{flex:1}}>
<Text style={styles.welcome}>
Welcome to React Natives
</Text>
</View>
<View style={{flex:1}}>
<Text style={styles.line1}>
line1
</Text>
</View>
<View style={{flex:1}}>
<Text style={styles.instructions}>
Press Cmd+R to reload,{'\n'}
Cmd+D or shake for dev menu
</Text>
</View>
</View>
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#F5FCFF',
borderWidth: 1,
flexDirection: 'row',
flexWrap: 'wrap',
},
welcome: {
fontSize: 20,
textAlign: 'center',
margin: 10,
borderWidth: 1,
},
line1: {
backgroundColor: '#FDD7E4',
},
instructions: {
textAlign: 'center',
color: '#333333',
marginBottom: 5,
borderWidth: 1,
},
Simply add alignSelf: "stretch" to your item's stylesheet.
line1: {
backgroundColor: '#FDD7E4',
alignSelf: 'stretch',
textAlign: 'center',
},
You should use Dimensions
First, define Dimensions.
import { Dimensions } from "react-native";
var width = Dimensions.get('window').width; //full width
var height = Dimensions.get('window').height; //full height
then, change line1 style like below:
line1: {
backgroundColor: '#FDD7E4',
width: width,
},
Editted:
In order to flex only the center text, a different approach can be taken - Unflex the other views.
Let flexDirection remain at 'column'
remove the alignItems : 'center' from container
add alignSelf:'center' to the textviews that you don't want to flex
You can wrap the Text component in a View component and give the View a flex of 1.
The flex will give :
100% width if the flexDirection:'row' in styles.container
100% height if the flexDirection:'column' in styles.container
Here you go:
Just change the line1 style as per below:
line1: {
backgroundColor: '#FDD7E4',
width:'100%',
alignSelf:'center'
}
First add Dimension component:
import { AppRegistry, Text, View,Dimensions } from 'react-native';
Second define Variables:
var height = Dimensions.get('window').height;
var width = Dimensions.get('window').width;
Third put it in your stylesheet:
textOutputView: {
flexDirection:'row',
paddingTop:20,
borderWidth:1,
borderColor:'red',
height:height*0.25,
backgroundColor:'darkgrey',
justifyContent:'flex-end'
}
Actually in this example I wanted to make responsive view and wanted to view only 0.25 of the screen view so I multiplied it with 0.25, if you wanted 100% of the screen don't multiply it with any thing like this:
textOutputView: {
flexDirection:'row',
paddingTop:20,
borderWidth:1,
borderColor:'red',
height:height,
backgroundColor:'darkgrey',
justifyContent:'flex-end'
}
Use javascript to get the width and height and add them in View's style.
To get full width and height, use Dimensions.get('window').width
https://facebook.github.io/react-native/docs/dimensions.html
getSize() {
return {
width: Dimensions.get('window').width,
height: Dimensions.get('window').height
}
}
and then,
<View style={[styles.overlay, this.getSize()]}>
width: '100%' and alignSelf: 'stretch' didn't work for me. Dimensions didn't suite my task cause I needed to operate on a deeply nested view. Here's what worked for me, if I rewrite your code. I just added some more Views and used flex properties to achieve the needed layout:
{/* a column */}
<View style={styles.container}>
{/* some rows here */}
<Text style={styles.welcome}>
Welcome to React Natives
</Text>
{/* this row should take all available width */}
<View style={{ flexDirection: 'row' }}>
{/* flex 1 makes the view take all available width */}
<View style={{ flex: 1 }}>
<Text style={styles.line1}>
line1
</Text>
</View>
{/* I also had a button here, to the right of the text */}
</View>
{/* the rest of the rows */}
<Text style={styles.instructions}>
Press Cmd+R to reload,{'\n'}
Cmd+D or shake for dev menu
</Text>
</View>
just remove the alignItems: 'center' in the container styles and add textAlign: "center" to the line1 style like given below.
It will work well
container: {
flex: 1,
justifyContent: 'center',
backgroundColor: '#F5FCFF',
borderWidth: 1,
}
line1: {
backgroundColor: '#FDD7E4',
textAlign:'center'
},
Style ={{width : "100%"}}
try this:
StyleSheet generated: {
"width": "80%",
"textAlign": "center",
"marginTop": 21.8625,
"fontWeight": "bold",
"fontSize": 16,
"color": "rgb(24, 24, 24)",
"fontFamily": "Trajan Pro",
"textShadowColor": "rgba(255, 255, 255, 0.2)",
"textShadowOffset": {
"width": 0,
"height": 0.5
}
}
Noted: Try to fully understanding about flex concept.
<View style={{
flex: 2,
justifyContent: 'center',
alignItems: 'center'
}}>
<View style ={{
flex: 1,
alignItems: 'center,
height: 50,
borderWidth: 1,
borderColor: '#000'
}}>
<Text>Welcome to React Nativ</Text>
</View>
<View style={{
flex: 1,
alignItems: 'center,
borderWidth: 1,
borderColor: 'red ',

<Text> line 1 </Text>
</View>
<View style={{
flex: 1,

borderWidth: 1,
borderColor: '#000'
}}>
<Text>
Press Cmd+R to reload,{'\n'}
Cmd+D or shake for dev menu
</Text>
</View>
</View>
Simply use width:'100%'
line1: {
backgroundColor: '#FDD7E4',
width: '100%'
},
I'm trying to place my icon on the same line as 2 Replies.
Here's a screenshot of how it looks:
I'd like to have it to the right of the line, as the arrow shows.
Here's how my Component's render function looks:
render: function() {
return (
<TouchableHighlight onPress={this.props.onSelect}>
<View style={styles.container}>
<Image source={{uri: this.state.image}}
style={styles.image} />
<View style={styles.postDetailsContainer}>
<Text style={styles.postTitle}>
{this.state.name}
</Text>
<Text style={styles.postDetailsLine}>
{this.state.comment}
</Text>
<View>
<Text style={styles.postChildrenDetails}>
{this.props.comment.child_comments_count} Replies
</Text>
<Icon
name='fontawesome|comments-o'
size={25}
color='#D6573D'
style={styles.icon}
/>
</View>
<View style={styles.separator} />
</View>
</View>
</TouchableHighlight>
)
}
Here's how my StyleSheet looks:
container: {
flex: 1,
flexDirection: 'row',
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#FFFFFD',
},
image: {
height: 48,
width: 48,
borderRadius: 25,
marginTop: 10,
alignSelf: 'center',
marginRight: 15,
marginLeft: 15
},
postDetailsContainer:{
flex: 1,
},
postTitle: {
fontSize: 15,
textAlign: 'left',
marginTop: 10,
marginBottom: 4,
marginRight: 10,
color: '#D6573D'
},
postDetailsLine: {
fontSize: 12,
marginRight: 10,
color: 'gray',
},
postChildrenDetails: {
fontSize: 12,
marginTop: 5,
marginBottom: 10,
marginRight: 10,
color: 'gray',
textAlign: 'right',
flex: 1
},
separator: {
height: 0.5,
backgroundColor: '#CCCCCC',
},
icon: {
flex: 1,
textAlign: 'right',
width: 25,
height: 25
}
})
I had the same challenge and for anyone having the same issue, here is how I went about solving it.
Wrap the Icon and the Text in a View like #Colin Ramsey said above in the comments
It will look like this:
<View style={{ flexDirection: 'row', justifyContent: 'space-between' }}>
<Icon name="ios-chat" size={20} />
<Text>
2 replies
</Text>
</View>
Shalom!
TRY THIS
<View
style={{
backgroundColor: "#ffc8cc",
borderRadius: 30,
margin: 5,
flexDirection: "row",
justifyContent: "space-between",
alignItems: "center",
paddingRight : 25
}}
>
<Text style={styles.title}>Leagues</Text>
<MaterialIcons name="sports-baseball" size={26} color="#cd000f" />
</View>
css for title :
title: {
fontSize: 18,
margin: 20,
color: "#cd000f",
},
Center image and text same line in props reactjs
<div style={{ alignItems: "center", display: "flex", justifyContent: "center" }} >
<img src={this.props.location.state.image} style={{ height: "100px", width: "100px", border: "4px solid white", verticalAlign: 'middle' }} />
<span style={{ fontSize: '40px', fontWeight: 'bolder', textAlign: 'center', verticalAlign: 'middle' }}>
{this.props.location.state.subject}</span>
</div>
