React Native text goes behind object - css

Hi Guys I have an issue where some text is being overlapped by another object.
Here is an image of what's happening.
You can see that the second line of text is behind the white shape, how can I make it so it becomes above the white shape? Ive tried z order and various other positions but can't get my head round this.
The code for this:
code for the white square:
const Square = () => {
return <View style={styles.square} />;
};
then the main code
<View style={{flex: 1, padding: 0}}>
{isLoading ? (
<Text>Loading...</Text>
) : (
<SafeAreaView style={{flex: 1, backgroundColor: '#8af542'}}>
<View
style={{
marginTop: 150,
alignItems: 'center',
justifyContent: 'center',
}}>
<Text>TEST</Text>
<Text
style={{
position: 'absolute',
top: 140,
zIndex: 1,
elevation: 1,
}}>
TEXT HERE
</Text>
</View>
<View
style={{
flex: 1,
justifyContent: 'flex-end',
marginBottom: windowHeight * -0.05,
}}>
<Square></Square>
</View>
</SafeAreaView>
)}
</View>
Then here are the styles:
const styles = StyleSheet.create({
centerItems: {
justifyContent: 'center',
alignItems: 'center',
},
square: {
width: windowWidth,
height: windowHeight * 0.6,
backgroundColor: 'white',
flex: 1,
justifyContent: 'flex-end',
marginBottom: windowHeight * -0.05,
position: 'absolute',
},
});

This is occuring because you have set the zIndex of the TEXT HERE view, and not the view that you want to have on the bottom. To resolve this, simply add the following to the square's view like so:
<View
style={{
marginTop: 150,
alignItems: 'center',
justifyContent: 'center',
zIndex: 100
}}>
<Text>TEST</Text>
<Text
style={{
position: 'absolute',
top: 140,
zIndex: 1,
elevation: 1,
}}>
TEXT HERE
</Text>
</View>
And then, if that does not help you, set the square's view zIndex: -1 like so:
<View
style={{
flex: 1,
justifyContent: 'flex-end',
marginBottom: windowHeight * -0.05,
zIndex: -1
}}>
<Square></Square>
</View>
When doing this, we are essentially telling the views to switch positions, and the view with the whitespace is being forced to the bottom.

React Native: Button at the right end of of Text

React Native learner here.
I am trying to show the suggestions as below:
<TouchableOpacity
style={{
backgroundColor: 'transparent',
flexDirection: 'row',
flexWrap: 'wrap',
}}
onPress={() => {
setSelectedValue(item);
setFilteredFilms([]);
}}>
<View>
<Text style={styles.itemText}>{item.title}</Text>
<Button
title={'Click'}
style={{
backgroundColor: 'green',
right: 0,
paddingRight: 0,
marginRight: 0,
}}></Button>
</View>
</TouchableOpacity>
...
itemText: {
fontSize: 15,
paddingTop: 5,
paddingBottom: 5,
margin: 2,
alignItems: 'flex-start',
},
infoText: {
textAlign: 'center',
fontSize: 16,
},
Output looks like below:
I want my suggestion's Text in the left side, while Click button always at the right side fixed with fixed length.
Text and Button region shouldn't overlap each other.
Any help or guidance about how to do it. Highly appreciated !!
P.S.: With style={{flexDirection: 'row'}} in <View> my Buttons in Suggestion box get pushed to right side and not visible as below:
I expect something like this:
You have to use flexDirection:'row' for inner View which contain the Text and the Button
<TouchableOpacity
style={{
backgroundColor: 'transparent',
flexDirection: 'row',
flexWrap: 'wrap',
justifyContent: 'space-between',
}}
onPress={() => {}}>
<Text style={{ maxWidth: '90%' }}>
{item.title}
</Text>
<View>
<Text style={{ backgroundColor: 'blue', alignItems: 'center' }}>
Click
</Text>
</View>
</TouchableOpacity>

View to fit the screen in React Native

Hello there guys
i have a problem with CSS in react native, i want to fit all my components in the screen without ScrollView but i cant seem to figure out what is my problem(i tried to change values for margins or paddings but it will look different in every device.)
As you can see at the attached image:
As you can see the graph below is not in the screen, i need to scroll view to the graph(which i dont want)
here is the code + css : (I dropped some lines to shorten the code(Like the carousel components and etc)
<View style={{ backgroundColor: "#fff" , flex: 1 }}>
<LinearGradient
colors={["#4c669f", "#3b5998", "#192f6a"]}
start={[0, 0]}
end={[1, 0]}
>
<View style={{ marginHorizontal: 20, paddingVertical: 48 }}>
<View style={styles.imageContainer}>
<View>
<View style={styles.check}>
<Ionicons name="md-checkmark" size={20} color={colors.pink} />
</View>
<Image
source={require("../assets/profile-pic.jpeg")}
style={{
width: 100,
height: 100,
borderRadius: 32,
}}
/>
</View>
</View>
<View style={[styles.center, { marginVertical: 12 }]}>
<Text style={styles.title}>
{currentUser.name + " " + currentUser.lastName}
</Text>
<Text style={[styles.subTitle, { marginTop: 8 }]}>
{businessDetails.bussinesName}
</Text>
</View>
</View>
</LinearGradient>
<View style={styles.container}>
<View style={styles.statContainer}>
<Text style={styles.statNumber}>1,700₪</Text>
<Text style={styles.stat}>הכנסה חודשית תופיע כאן</Text>
</View>
</View>
<View style={styles.center}>
<Text style={styles.textGraphTitle}>Graphs Analysis:</Text>
</View>
<View>
</View>
</View>
);
CSS:
center: {
alignItems: "center",
justifyContent: "center",
},
imageContainer: {
alignItems: "center",
justifyContent: "center",
marginTop: 1,
shadowColor: colors.darkBg,
shadowOffset: { height: 3, width: 1 },
shadowOpacity: 0.5,
},
container: {
paddingVertical: 24,
paddingHorizontal: 32,
marginBottom: 8,
backgroundColor: colors.lightBg,
flexDirection: "row",
justifyContent: "space-between",
marginHorizontal: 16,
borderRadius: 16,
marginTop: -48,
},
statContainer: {
alignItems: "center",
justifyContent: "center",
flex: 1,
},
You are asking responsive app design. Basically, you can use for width and height percentages or dimension.
import { Dimensions} from 'react-native'
const {width, height} = Dimensions.get('window')
One more approach is to use react-native-screens library

Height of View in react native

Is it possible to make the <View /> having the same height? I am fetching a data from server side and some content are short and some are long. So when I display them in a box form, the height of the box aren't same. If I fix the height or minimum height the long text will exceed the height of the box.
EDIT : Sample code
DisplayEguides(){
var winsWidth = Dimensions.get('window').width;
if(this.state.eguides != null){
var eguides = this.state.eguides.map((data, i)=>(
<View key={i} style={[ { width: (60/100)*winsWidth, paddingHorizontal: 5 } ]}>
<TouchableOpacity
onPress={()=>this.OpenUrl(data.url)}
style={{ backgroundColor: '#ffffff', borderBottomWidth: 1, borderColor: '#efefef', elevation: 1, shadowOpacity: 0.8, marginBottom: 15, padding: 15, borderRadius: 15 }}>
<View style={{ alignItems: 'center', overflow: 'hidden', position: 'relative' }}>
<Text style={{ fontWeight: 'bold', textAlign: 'center', marginBottom: 15 }}>{ data.title }</Text>
<View style={{ flexDirection: 'row', alignItems: 'center', justifyContent: 'center' }}>
<Text style={{ color: Color.default, fontWeight: 'bold' }}>Download</Text>
<AntDesign name="download" size={16} color={Color.default} style={{ paddingLeft: 10, fontWeight: 'bold' }} />
</View>
</View>
</TouchableOpacity>
</View>
))
return (
<View style={{ paddingHorizontal: 15 }}>
<AppText type="bold" style={{ fontSize: 18, marginBottom: 15 }}>E-Guides</AppText>
<ScrollView horizontal={true} showsHorizontalScrollIndicator={false}>{ eguides }</ScrollView>
</View>
);
}
}
Seems like Flexbox in react native is doing the job but need to place at the right element. Setting the view to flex: 1 will auto adjust all content inside it to have the same height. In my case, I have to set flex: 1 at TouchableOpacity since my box style is in this element.
<TouchableOpacity
onPress={()=>this.OpenUrl(data.url)}
style={{ backgroundColor: '#ffffff', borderBottomWidth: 1, borderColor: '#efefef', elevation: 1, shadowOpacity: 0.8, marginBottom: 15, padding: 15, borderRadius: 15, flex: 1 }}>
{ /* The rest of code goes here */ }
</TouchableOpacity>

How to get rounded image tag on top of two div in react native?

I want to create a profile page where rounded image will be on top of two div in 30:70 ratio where top div will be empty and bottom div will contain few items. I have tried few code snippets from web.
<View style={{ flex: 1, flexDirection: 'column', backgroundColor: 'green', justifyContent: 'flex-start', alignItems: 'flex-start' }}>
<View style={{ flexDirection: 'column', justifyContent: "flex-start", alignItems: "flex-start", alignSelf: "flex-start" }}>
{/* <View style={{ flex: 1, flexDirection: 'row', alignItems: 'flex-end', alignSelf: 'flex-start', margin: 1 }}> */}
<View style={{ backgroundColor: 'white', borderRadius: 10, flexDirection: 'column', height: "30%", width: "100%" }}></View>
{/* </View> */}
<View style={{ flex: 1, flexDirection: 'row', alignItems: 'flex-start', alignSelf: 'flex-start', margin: 1 }}>
<View style={{ backgroundColor: 'white', borderRadius: 10, flexDirection: 'column', height: "70%", width: "100%" }}></View>
</View>
</View>
<View style={{ justifyContent: 'center', alignItems: 'center', alignSelf: 'center', position: 'absolute' }}>
<View style={{
backgroundColor: 'blue',
borderRadius: 10, height: 100, width: 100, borderRadius: 100 / 2
}}></View>
</View>
</View>
reference image
Taking as reference the image you share with us... You can have two views and set the profile avatar style to:
{
position: 'absolute',
alignSelf: 'center',
etc..
}
Check a quick demo: https://snack.expo.io/#abranhe/avatar-example
App.js
import React, { Component } from 'react';
import { Text, View, StyleSheet, ImageBackground, Image } from 'react-native';
import { Ionicons, FontAwesome } from '#expo/vector-icons';
import Constants from 'expo-constants';
import { avatar, background } from './data';
export default class App extends Component {
renderRow({ action, icon, fontAwesome = false }) {
return (
<View style={styles.actionRow}>
{fontAwesome
? <FontAwesome name={icon} size={25} />
: <Ionicons name={icon} size={32} />}
<Text style={styles.text}>{action}</Text>
</View>
);
}
render() {
return (
<View style={styles.container}>
<ImageBackground source={background} style={styles.background}>
<Image source={avatar} style={styles.avatar} />
</ImageBackground>
<View style={styles.content}>
{this.renderRow({ action: 'Scanner', icon: 'ios-camera' })}
{this.renderRow({
action: 'Profile',
icon: 'user-circle-o',
fontAwesome: true,
})}
</View>
</View>
);
}
}
You styles:
const styles = StyleSheet.create({
container: {
flex: 1,
},
background: {
width: '100%',
height: 130,
},
content: {
flex: 1,
marginTop: 80,
marginHorizontal: 10,
},
avatar: {
width: 100,
height: 100,
borderRadius: '50%',
borderWidth: 0.7,
borderColor: 'black',
position: 'absolute',
alignSelf: 'center',
marginTop: 80,
},
actionRow: {
width: '100%',
height: '50',
flexDirection: 'row',
alignItems: 'center',
margin: 10,
},
text: {
marginLeft: 15,
fontWeight: '500',
},
});

Enable overflow in native-base cards

I have a component in a website that looks like this:
Regular card
It's basically a div with an image inside it, but the image has a margin-top of -50 so that it overflows off the card.
I would like to accomplish the same thing with react-native and native-base. Here is the relevant code:
render() {
return (
<View style={styles.container}>
<Card>
<CardItem style={{ marginTop: -50, justifyContent: 'center' }}>
<Image style={styles.image} source={{ uri: this.state.band.imageComponent.link }} />
</CardItem>
</Card>
</View>
)
}
const styles = StyleSheet.create({
container: {
flex: 1,
marginTop: 150
},
image: {
width: 150,
height: 150,
)
And the result looks like this:
React-native card
As you can see, the picture is cutoff at the top. How can I keep the image overflow and have it overlay the card like in my first image?
Overflow is not supported in Android. There are lots of open issues for that. Check some of them here and here.
Here's an npm package that apparently solves that issue that you could try.
Otherwise you can use a workaround for that I found on this medium post.
According to your image you have to wrap your image and the container inside another View as siblings and then position them absolutely.
Here's the code that I tweaked a little bit from that post. You can replace the View according to your Card and CardItem styles.
<View style={styles.container}>
<View style={styles.cardSection1}>
<Image style={styles.image} source={{ uri: 'https://imgplaceholder.com/420x320/ff7f7f/333333/fa-image' }} />
</View>
<View style={styles.cardSection2}>
</View>
</View>
const styles = {
container: {
flex: 1,
backgroundColor: 'grey',
alignItems: 'center'
},
image: {
width: 150,
height: 150,
},
cardSection1: {
alignItems: 'center',
justifyContent: 'center',
position: 'absolute',
width: 100,
height: 100,
borderRadius: 50 / 2,
zIndex: 2,
shadowColor: '#000',
shadowOffset: { width: 0, height: 0 },
shadowOpacity: 0.2,
shadowRadius: 10,
elevation: 7,
},
cardSection2: {
alignItems: 'center',
justifyContent: 'center',
position: 'absolute',
top: 25,
width: 300,
height: 150,
borderRadius: 8,
backgroundColor: 'white',
zIndex: 1,
shadowColor: '#000',
shadowOffset: { width: 0, height: 0 },
shadowOpacity: 0.2,
shadowRadius: 10,
elevation: 5,
}
}
This is the output that I got.
//import liraries
import React, { Component } from 'react';
import { View, Text, StyleSheet,TextInput,Dimensions,Image } from 'react-native';
