React Native broken up border - css

I am looking for some styling guidance for React-Native. I am wanting to create a border that only has a certain amount of the corners colored. Something like this:
I currently have this:
captureSquare: {
height: 450,
width: 450,
borderWidth: 2,
borderColor: '#FFFFFF,
backgroundColor: 'transparent',
justifyContent: 'center',
alignItems: 'center',
},
I am not sure how to break up the borders. Any ideas?

Was able to do this by adding 4 <View />s to the captureSqaure and giving them the following properties:
topLeftEdge: {
position: 'absolute',
top: 0,
left: 0,
height: 25,
width: 25,
borderColor: '#FFFFFF,
borderLeftWidth: 3,
borderTopWidth: 3,
},

React Native : shadows behavior

Hello React Native developers,
The code below produces the image in caption. I'm just wondering why the shadow of the first view (with the icon) is diminished compared to the black view. I added visible borders so you can see the difference between the two shadows. The "issue" both applies to Android & iOS platforms.
Is this really an issue or this is just normal behavior ?
<>
<View
style={{
alignSelf: 'center',
marginTop: 50,
width: 50,
height: 50,
shadowColor: '#000',
shadowOffset: {
width: 0,
height: 0,
},
shadowOpacity: 1,
shadowRadius: 16.0,
borderRadius: 1000,
borderColor: 'red',
borderWidth: 1,
}}>
<Icon name="cog" type="ionicons" color="black" size={50} />
</View>
<View
style={{
alignSelf: 'center',
marginTop: 50,
width: 50,
height: 50,
shadowColor: '#000',
shadowOffset: {
width: 0,
height: 0,
},
shadowOpacity: 1,
shadowRadius: 16.0,
backgroundColor: '#000',
borderRadius: 1000,
borderColor: 'red',
borderWidth: 1,
}}
/>
</>
Some function in React Native shadow works badly. Try to use https://github.com/SrBrahma/react-native-shadow-2 instead.
import { Shadow } from 'react-native-shadow-2';
<Shadow>
<Text style={{ margin: 20, fontSize: 20 }}>🙂</Text>
</Shadow>

Can you have a parent allow one absolutely positioned child to overflow and one to not overflow in React Native?

I have a parent element with 2 absolutely positioned children inside. I want one of the children's overflow to be visible and the other's overflow to be hidden. Like so:
Adding overflow: 'hidden to the parent hides the overflow of both the coin image and the 'most popular' sash but I want the coin image overflow to be visible.
container: {
width: 155,
height: 145,
backgroundColor: Colours.white,
borderRadius: 10,
borderColor: Colours.borderTwo,
borderWidth: 1,
alignItems: 'center',
justifyContent: 'flex-end',
margin: 10,
marginBottom: 25,
paddingBottom: 10,
overflow: 'hidden',
},
mostPopularSash: {
position: 'absolute',
top: 2,
right: -30,
backgroundColor: Colours.yellow,
width: 100,
height: 40,
alignItems: 'center',
justifyContent: 'center',
transform: [{rotate: '40deg'}],
},
imageContainer: {
position: 'absolute',
top: -22,
width: 52,
height: 52,
borderRadius: 100,
backgroundColor: Colours.white,
borderColor: Colours.pageColour,
borderWidth: 1,
justifyContent: 'center',
alignItems: 'center',
shadowColor: '#171717',
shadowOffset: {width: 0, height: 3},
shadowOpacity: 0.2,
shadowRadius: 2,
elevation: 5,
},
image: {
width: 40,
height: 40,
},
I've tried adding zIndex: 2 to the image container and then zIndex: 1 to the parents parent but it didn't work..
Can't find much online to solve this problem as most queries related to 'overflow' are requesting the opposite effect.
Any help would be much appreciated!
In iOS you can play with the zIndex
You can create a prop or a state that tells you which one is active.
For instance,
<View style={{zIndex:2}}>
{data.map(item => <CustomComp active={item.active} /> )}
</View>
In customcomp, you can set the parent style such as
style={{ props.active ? 3 : 1 }}
Make sure you have assign the zIndex to the container view
Manage to get the desired effect by wrapping the container that uses overflow: 'hidden' inside an outer container and then moving the imageContainer out of the container and into the outer container giving it zIndex: 1 and keeping it absolutely positioned as well as giving it alignSelf: 'center'
Like so:
outerContainer: {
width: '45%',
margin: 10,
},
container: {
height: 145,
width: '100%',
backgroundColor: Colours.white,
borderRadius: 10,
borderColor: Colours.borderTwo,
borderWidth: 1,
alignItems: 'center',
justifyContent: 'flex-end',
marginBottom: 25,
paddingBottom: 10,
overflow: 'hidden',
},
mostPopularSash: {
position: 'absolute',
top: 2,
right: -30,
backgroundColor: Colours.yellow,
width: 100,
height: 40,
alignItems: 'center',
justifyContent: 'center',
transform: [{rotate: '40deg'}],
},
imageContainer: {
zIndex: 1,
position: 'absolute',
top: -22,
alignSelf: 'center',
width: 52,
height: 52,
borderRadius: 100,
backgroundColor: Colours.white,
borderColor: Colours.pageColour,
borderWidth: 1,
justifyContent: 'center',
alignItems: 'center',
shadowColor: '#171717',
shadowOffset: {width: 0, height: 3},
shadowOpacity: 0.2,
shadowRadius: 2,
elevation: 5,
},
image: {
width: 40,
height: 40,
},
<View style={styles.outerContainer}>
<View style={styles.imageContainer}>
<Image source={image} style={styles.image} />
</View>
<View style={styles.container}>
{mostPopular && (
<View style={styles.mostPopularSash}>
<Text style={styles.mostPopularText}>Most</Text>
<Text style={styles.mostPopularText}>Popular</Text>
</View>
)}
<View style={styles.contentContainer}>
<View style={styles.textContainer}>
<Text style={styles.amountText}>£{amount}</Text>
<Text style={styles.bonusGemsText}>+{gemsBonus} NGems Bonus</Text>
</View>
<Button
text="Deposit"
backgroundColor={Colours.primary}
fontWeight="400"
fontColour={Colours.white}
fontSize={14}
style={{marginBottom: 0, height: 35, marginTop: 10}}
onPress={() => setModalVisible(true)}
/>
</View>
</View>
</View>

Image inside a View element is not aligning to the right in React Native

I am implementing a tile in reactnative and I have to make the Image right in the tile just like this
What I want (click here)
and this is what I can implement till now
What I get ()
this is my code
<View style={styles.container} >
<Image
style={styles.image}
source={item.image}

<Text style={styles.subText}>{item.title}</Text>
<Text style={styles.headingText}>{item.message}</Text>
</View>
</View>
and this is style
const styles = StyleSheet.create({
container: {
backgroundColor: '#206c72',
alignItems: 'flex-end',
borderRadius: 15,
width: COURSE_ITEM_WIDTH,
elevation: 7,

borderRadius: 10
}
})
Please help me i dont know what i am doing wrong. thanks in advance!
[note: please ignore the content, focus on alignment]
Your image is aligned to the right but there is nothing at the left of it. You should add flexDirection:'row' to the parent container and put an empty View with width : 40px before your image.
You can also remove the alignItems:flex-end and justifyContent:center from the main container
You can add alignSelf property to flex-end for image and image will be on end of the tile.
example 1:
image: {
width: "50%",
height: 120,
borderRadius: 10,
backgroundColor: "red", //for making sure how much space is taken by image you can remove on further
alignSelf: "flex-end"
},
for reference i tried a sandbox example check it out here
also noticed you are using alignItems value twice first one is only necessary you can remove 2nd alignItems and position relative value from styles.container then it will align the image to end. you will get the exact result you want
example 2:
container: {
backgroundColor: '#206c72',
alignItems: 'flex-end', // only need this alignItems
borderRadius: 15,
width: COURSE_ITEM_WIDTH,
elevation: 7,
justifyContent: 'center',
marginTop: 20
},
image: {
width: "50%",
height: 120,
borderRadius: 10,
backgroundColor: "red", //for making sure how much space is taken by image you can remove on further
// no need of alignSelf to flex-end here
},

Cross button react-native

I thought this would be simple to produce but I can't seem to get it looking right, I just want an X button - created 2 Views with 45deg rotation but for some reason they dont look equal length.
Header.js
<View style={styles.hamburgerContainer}>
<View style={[styles.hamburgerLine, styles.crossLine1]}></View>
<View style={[styles.hamburgerLine, styles.crossLine2]}></View>
</View>
const styles = StyleSheet.create({
hamburgerContainer: {
width: 40,
height: 40,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: 'transparent',
},
hamburgerLine: {
height: 3,
width: 30,
marginVertical: 3,
backgroundColor: Colors.primary,
},
crossLine1: {
marginVertical: 0,
transform: [{rotate: '45deg'}],
},
crossLine2: {
marginVertical: 0,
transform: [{rotate: '-45deg'}],
},
})
Result:
Appreciate any help here
Make the position absolute for the lines so they start on the same axis and can overlap:
hamburgerLine: {
height: 10,
width: 300,
marginVertical: 3,
backgroundColor: Colors.primary,
position: 'absolute' //add this
},

React Native - manipulate View to apply shadow to Image's BorderRadius?

Having some styling issues on React Native with Shadows.
I'd like to get a shadow on just the image, which has curved edges (not a square) with the borderradius I've given it. But if I apply a shadow on the parent View, it can't seem to 'follow the edges' of the Image. I'd like for the shadow to be around the curved edges of the Image, not around the square view.
Here is my code:
<View style={[styles.closedcontainer]}>
<Image source={{uri: props.food.url}}
style={styles.smallimage}
/>
</View>
And here is my styling:
const styles = StyleSheet.create({
closedcontainer: {
height: 100,
width: 100,
flexDirection: 'row',
flexWrap: 'wrap',
paddingLeft: 50,
paddingRight: 50,
paddingBottom: 0,
paddingTop: 0,
flex: 1,
alignItems: 'center',
justifyContent: 'center',
backgroundColor: '#fff9f9',
shadowColor: 'black',
shadowOffset: {width: 2, height: 5},
shadowOpacity: .30,
shadowRadius: 5,
// overflow: 'hidden'
},
smallimage: {
height: 100,
width: 100,
borderRadius: 30,
borderColor: "#f97070",
borderWidth: 2.75,
margin: 10,
backgroundColor: 'white',
resizeMode: 'contain'
}
I thought perhaps adding overflow hidden to the parent View's styling (closedcontainer) would do it, but that gets hides the whole shadow altogether.
Any ideas? Thanks!
UPDATE: per suggestion, tried setting the borderRadius directly in the , unfortunately still no luck.
Try setting borderRadius directly as a prop on the image instead using it as a style.
<Image borderRadius={25}/>
Or similar
