I can't figure out how to make my component touchable. I have one wrapper which has position: relative and two elements with position: absolute. I would like to make this wrapper touchable but it doesn't work with any Touchable component from react-native.
This backgroundColor is just for testing.
<View style={styles.container}>
<TouchableHighlight onPress={() => { console.log('touched') }}>
<View style={styles.wrapper}>
<View style={styles.wrapperForImage} />
<Text style={styles.text} >{text.toUpperCase()}</Text>
</View>
</TouchableHighlight>
</View>
const styles = StyleSheet.create({
container: {
flex: 1,
alignItems: 'center',
justifyContent: 'center'
},
wrapper: {
position: 'relative',
flex: 1,
alignItems: 'center',
justifyContent: 'center'
},
wrapperForImage: {
position: 'absolute',
width: 200,
height: 200,
backgroundColor: 'red'
},
text: {
position: 'absolute',
width: 100,
height: 100,
zIndex: 10,
textAlign: 'center',
color: '#000',
fontSize: 14,
lineHeight: 23
}
});
Dependencies:
"dependencies": {
"expo": "^31.0.0",
"react": "16.5.0",
"react-native": "https://github.com/expo/react-native/archive/sdk-31.0.0.tar.gz",
"react-native-extended-stylesheet": "^0.10.0",
"tslib": "^1.9.3"
}
You need to give height and width for TouchableHighlight:
<View style={styles.container}>
<TouchableHighlight style={{
backgroundColor: 'green',
height: '100%',
width: '100%',
}}
onPress={() => { alert('touched') }}>
<View style={styles.wrapper}>
<View style={styles.wrapperForImage} />
<Text style={styles.text} >TEXT</Text>
</View>
</TouchableHighlight>
</View>
my solution on Android was to remove the elevation style from the parent container.

How can I put a Vertical progress bar on React Native
I need to make a delivery bar progress
**Example: driver is at point A and needs to go to point B ...*
This is a bit tricky but do able. You will have to have a vertical line and place the items horizontally in a row format.
Lets say you have a data structure like this.You can update the current location using the flag and set the labels.
const data = [
{ title: 'Stop 1', letter: 'A', isCurrent: false },
{ title: 'Stop 2', letter: 'B', isCurrent: false },
{ title: 'Stop 3', letter: 'C', isCurrent: false },
{ title: 'Stop 4', letter: 'D', isCurrent: true },
{ title: 'Stop 5', letter: 'E', isCurrent: false },
];
This will be your component which handle the map
const MapProgress = (props) => {
if (!props.data || props.data.lenght === 0) return null;
const firstItem = props.data.shift();
return (
<View style={{ flex: 1 }}>
<View style={styles.verticalLine}></View>
<View style={styles.verticalWrap}>
<View style={styles.itemWrap}>
<View style={styles.firstPoint}></View>
<View style={{ marginLeft: 5, flex: 1 }}>
<Text>{firstItem.title}</Text>
</View>
</View>
{props.data.map((item) => (
<View style={styles.itemWrap}>
<View style={styles.pointWrap}>
<Text
style={[
styles.markerText,
item.isCurrent ? styles.currentMarker : null,
]}>
{item.letter}
</Text>
</View>
<View style={{ marginLeft: 5, flex: 1 }}>
<Text style={item.isCurrent ? styles.currentMarker : null}>
{item.title}
</Text>
</View>
</View>
))}
</View>
</View>
);
};
These will have to be styled to place the views properly
const styles = StyleSheet.create({
verticalLine: {
backgroundColor: 'black',
width: 2,
height: '95%',
position: 'absolute',
marginLeft: 35,
marginTop: 20,
},
verticalWrap: {
justifyContent: 'space-between',
height: '100%',
},
itemWrap: {
width: 200,
height: 40,
borderWidth: 1,
marginLeft: 20,
justifyContent: 'center',
flexDirection: 'row',
alignItems: 'center',
},
pointWrap: {
backgroundColor: 'black',
height: 20,
width: 20,
marginLeft: 5,
alignItems: 'center',
},
firstPoint: {
backgroundColor: 'black',
borderRadius: 20,
height: 10,
width: 10,
marginLeft: 10,
},
markerText: { color: 'white' },
currentMarker: { color: 'green' },
});
You can use the component like this
<MapProgress data={data} />
You can tryout the snack below
https://snack.expo.io/#guruparan/mapprogress
You better try this lib: https://github.com/oblador/react-native-progress#progressbar
Or you can create a your custom progressbar, it pretty simple in React Native. You could try
<View style={{height: 50, width: '100%', flexDirection: 'row'}}>
<View style={{height: '100%', flex: this.state.currentProgress, backgroundColor: "blue"}}/>
<View style={{height: '100%', flex: 100 - this.state.currentProgress, backgroundColor: "grey"}}/>
</View>
I think that it.
For vertical progress bar. You cane use
react-native-progress npm and simply rotate the bar using style transform property.
import React from 'react';
import * as Progress from 'react-native-progress';
return <Progress progress={progress} style={{ transform: [{ rotate: '-90deg' }] }} />;

This is design that I want to implement for my mobile application:
And this is what is currently accomplished to implement:
Implemented design
As you can see folowing some online examples i manage to curve the picture but its curved on both ends instead of just on the bottom.
This is my style code:
const mainStyle = StyleSheet.create({
container: {
flex: 1,
flexDirection: "column",
backgroundColor: "#d3c586",
alignItems: "center",
justifyContent: "space-between",
},
cardContainer: {
flex: 1,
alignSelf: "center",
backgroundColor: "#d3c586",
alignItems: "center",
justifyContent: "space-between",
overflow: "hidden",
},
cardImageContainer: {
flex: 0.6,
borderRadius: width,
width: width,
height: width,
bottom: 0,
overflow: 'hidden',
},
cardImage: {
height: height / 2,
width: width,
bottom: 0,
marginLeft: 0,
}};
This is a list of items that can be swiped and i render it from this function:
renderItem ({item, index}) {
return (
<View style={mainStyle.cardContainer}>
<View style={mainStyle.cardImageContainer}>
<TouchableOpacity onPress={(event) => this.handleDoubleTap(item)} onLongPress={(event) => this.handlePictureShare(item)}>
<LoadImage style={mainStyle.cardImage} source={{uri: item.url}} thumbnailSource={{uri: item.url}}/>
</TouchableOpacity>
</View>
<View style={mainStyle.cardTextContainer}>
<Text numberOfLines={25} style={{fontSize: 19}}>{item.fact}</Text>
</View>
</View>
)
}
I do not have a lot of experience with CSS since most of my work is on the backend.
Check these links BorderBottomLeftRadius BorderBottomRightRadius
This way you can only give radius bottom of your image.
You can try like this:
import React, { Component } from 'react';
import { View } from 'react-native';
export default class FlexDirectionBasics extends Component {
render() {
return (
// Try setting `flexDirection` to `column`.
<View style={{flex: 1, flexDirection: 'row', alignItems: 'center', justifyContent: 'center'}}>
<View style={{width: 100, height: 100, backgroundColor: 'steelblue', borderBottomColor: 'black', borderBottomEndRadius: 10, borderBottomStartRadius: 10 }} />
</View>
);
}
}

If you run the above code in android then change behavior={"height"}
I'm having an issue with React Native. I'm trying to put an image as a header, which needs to resize itself responsively to fit inside of the viewport and be centred horizontally.
Unfortunately, I'm unable to produce any sort of result using styling arguments such as resizeMode: 'contain' and the image disappears when following the advice of people who say to use the styling arguments width: undefined and height: undefined.
I'm a bit new to React Native so it's certainly possible that there's a blindingly obvious issue with how I'm approaching this problem. I'm also new to posting on Stack Overflow so any pointers about how best to describe or show my problem would also be most welcome.
Here is the source code I am using which produces the result where the image is too big for the screen:
export default class ComponentIndex extends React.Component {
render(){
return(
<ImageBackground
source={require('./../../assets/images/background_placeholder.png')}
style={{width: '100%', height: '100%'}}
>
<View style={styles.parentView}>
<View style={styles.elementSpacer}>
<Image
source={require('./../../assets/images/iview_learning_logo.png')}
style={styles.headerImage}
/>
</View>
<View style={styles.elementContainer}>
<Text style={styles.subheadingText}>App for comprehensive tutorials</Text>
</View>
<View style={styles.elementContainer}>
<Button rounded style={styles.startButton}>
<Text style={styles.startButtonText}>LET'S GO</Text>
</Button>
</View>
</View>
</ImageBackground>
);
}
}
const styles = StyleSheet.create({
parentView: {
flex: 1,
flexDirection: 'column',
padding: 30,
justifyContent: 'center',
},
headerImage: {
resizeMode: 'contain',
},
elementSpacer: {
flex: 1,
},
elementContainerHeader: {
height: 60,
},
elementContainer: {
margin: 10,
},
subheadingText: {
fontSize: 18,
textAlign: 'center',
//fontFamily: 'Arial',
},
startButton: {
alignItems: 'center',
justifyContent: 'center',
alignSelf: 'center',
paddingRight: 25,
paddingLeft: 25,
backgroundColor: '#c00000',
},
startButtonText: {
color: 'white',
//fontWeight: 'bold',
fontSize: 20,
//fontFamily: 'Arial',
},
});
Image going off the side of the screen
And here is the Source Code I am using where the image disappears off the screen:
export default class ComponentIndex extends React.Component {
render(){
return(
<ImageBackground
source={require('./../../assets/images/background_placeholder.png')}
style={{width: '100%', height: '100%'}}
>
<View style={styles.parentView}>
<View style={styles.elementSpacer}>
<Image
source={require('./../../assets/images/iview_learning_logo.png')}
style={styles.headerImage}
/>
</View>
<View style={styles.elementContainer}>
<Text style={styles.subheadingText}>App for comprehensive tutorials</Text>
</View>
<View style={styles.elementContainer}>
<Button rounded style={styles.startButton}>
<Text style={styles.startButtonText}>LET'S GO</Text>
</Button>
</View>
</View>
</ImageBackground>
);
}
}
const styles = StyleSheet.create({
parentView: {
flex: 1,
flexDirection: 'column',
padding: 30,
justifyContent: 'center',
},
headerImage: {
resizeMode: 'contain',
height: undefined,
width: undefined,
},
elementSpacer: {
flex: 1,
},
elementContainerHeader: {
height: 60,
},
elementContainer: {
margin: 10,
},
subheadingText: {
fontSize: 18,
textAlign: 'center',
//fontFamily: 'Arial',
},
startButton: {
alignItems: 'center',
justifyContent: 'center',
alignSelf: 'center',
paddingRight: 25,
paddingLeft: 25,
backgroundColor: '#c00000',
},
startButtonText: {
color: 'white',
//fontWeight: 'bold',
fontSize: 20,
//fontFamily: 'Arial',
},
});
Image disappeared entirely
After viewing the related questions, I found a solution which worked for me. Adding the following styling arguments did the trick:
width: null,
resizeMode: 'contain',
height: 220
The Stack Overflow question this solution was taken from
I'm trying to make two nested swipers on Android with React Native, using react-native-swiper. Each swiper works correctly when is separate, but when I add one to the other, the inner nested swiper doesn't show any content. It's a little bit weird, it recognized its children, I can swipe but Views are not rendered. Here is my simple demonstration example:
import React from 'react'
import {
Text,
View
} from 'react-native'
import Swiper from 'react-native-swiper'
const Dimensions = require('Dimensions');
const window = Dimensions.get('window');
var styles = {
wrapper: {
backgroundColor: 'transparent'
},
innerSwiper: {
width: window.width,
height: window.height / 3,
marginTop: 60,
backgroundColor: '#92BBD9'
},
slide1: {
flex: 1,
alignItems: 'center',
backgroundColor: '#9DD6EB'
},
slide2: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#97CAE5'
},
slide3: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#92BBD9'
},
text: {
color: '#fff',
fontSize: 30,
fontWeight: 'bold'
}
}
export default () =>
<Swiper style={styles.wrapper} showsButtons>
<View style={styles.slide1}>
<View style={styles.innerSwiper}>
<Swiper style={styles.wrapper} showsButtons>
<View style={styles.slide1}>
