Flex Layout with React Native - react-native

I'm having an issue where my container is collapsing on my child components which consists of a list of 4 images and one icon at the end of the container in a row. If I set the height explicitly then I can make it large enough to fit the content for one device. However, I have the images resizing themselves right now based off of width of the phone and a percent and then scaling to conserve aspect ratio. Is there a way to make my container grow just large enough to ensure it fits its child components when its child components scale based off of device width?
I thought that React Native flex default was to do this but for whatever reason my container is not fitting the images inside it but instead shrinking and all inside content is shrinking down except the images which lay over the top of my now shrunk containers.
export default function BadgeQuickView() {
return (
<View style={styles.badgeViewContainer}>
<View style={styles.badgeContainerTop}>
<View style={styles.badgeContainerLeftBorder}></View>
<Text style={styles.badgeContainerTitle}>FEATURED BADGES</Text>
<View style={styles.badgeContainerRightBorder}></View>
</View>
<View style={styles.quickBadgeList}>
{TEST_BADGE_ARRAY.map(option => (
<View style={styles.badgeInfoContainer} key={option.id}>
<Image style={styles.badgeImage} source={{uri: option.url}} fadeDuration={0} />
<Text style={styles.badgeDescText}>{option.name}</Text>
</View>
))}
<View style={styles.moreBadgesButtonContainer}>
<TouchableOpacity style={styles.moreBadgesButton}>
<Text style={styles.moreBadgesText}>All {`\n`} Badges</Text>
<Entypo name={'dots-three-horizontal'} size={moderateScale(20)} color={profileColors.editProfileText}/>
</TouchableOpacity>
</View>
</View>
</View>
);
}
const styles = StyleSheet.create({
badgeViewContainer: {
width: '100%',
height: moderateScale(130),
borderStyle: 'solid',
borderColor: userInterface.borderColor,
borderBottomWidth: 2,

},

justifyContent: 'space-around',
paddingLeft: 15,
},
badgeImage: {

width: '100%',
height: undefined,
resizeMode: 'contain',
marginBottom: 10,
},
moreBadgesButton: {
height: '100%',
width: '100%',
alignItems: 'center',
justifyContent: 'center',
textAlign: 'center'
},
moreBadgesButtonContainer: {
height: '100%',
width: '15%',
},
badgeInfoContainer: {
height: '100%',
width: '20%',
flexDirection: 'column',
padding: 5,
},
badgeContainerTop: {
flexDirection: 'row',
alignItems: 'center',
},
badgeContainerLeftBorder: {
borderStyle: 'solid',
borderColor: userInterface.borderColor,
borderTopWidth: 2,
width: '5%',
bottom: moderateScale(13) / 2,
},
badgeContainerTitle: {
fontFamily: 'montserrat-bold',
color: profileColors.editProfileText,
marginHorizontal: 10,
fontSize: moderateScale(13),
bottom: moderateScale(13) /2,
},
badgeContainerRightBorder: {
borderStyle: 'solid',
borderColor: userInterface.borderColor,
borderTopWidth: 2,
width: '100%',
bottom: moderateScale(13) / 2,
},
});
** Edit: Added current working code for reference. moderateScale(...) is just taking the screenHeight and scaling the height and working for most devices that I have tested thus far. I would like to not have to set this explicitly though if possible and instead have it expand based on its content.
Below is the desired and undesired looks. When I comment out the height: from the view container and set it to flex it won't expand to fit its content. When real images are added in the images show over the top of the bottom border and the text is not visible at all that will show under the red box typically. Added the red just as an indicator of where the image and text renders.

How to prevent the style of the annotation point from appearing to be lost, it turns completely black?

I am using the react-native-mapbox-gl library and I am showing some points on a map. Each has its own callout to display additional information when the respective point is pressed.
I have found the docs/Callout.md and Callout.js source and and example using it in example/src/examples/ShowPointAnnotation.js. This was a great help, thank you so much for the example... I might though doing something really wrong and I have spent days already on this...
My issue is that when I press one annotation, the styling of the annotations appears to be lost (they go all black). Similarity, the styling for the callouts don't seem to be applied. They all black, too. I have shared code and screenshots bellow.
<MapboxGL.PointAnnotation
key={id}
id={id}
coordinate={coordinate}
title={title}
onSelected={feature => {
debugger
this.onAnnotationSelected(i, feature)
}}
onDeselected={this.onAnnotationDeselected}
>
<View
style={[
styles.annotationContainer,
{
backgroundColor: bgColour,
borderRadius: ANNOTATION_SIZE / 2,
borderWidth: StyleSheet.hairlineWidth,
borderColor: borderColor
}
]}
>
<Text style={[styles.annotationFill, { color: borderColor }]}>
{studio.id}
</Text>
</View>
<MapboxGL.Callout
style={[
styles.calloutContainer,
{ backgroundColor: bgColour, borderColor: borderColor }
]}
title={title}
>
<View
style={[
styles.calloutContent,
{
backgroundColor: bgColour,
borderColor: borderColor
}
]}
>
<Text style={[styles.annotationFill, { color: borderColor }]}>
{title}
</Text>
</View>
<View
style={[
styles.tip,
styles.calloutContent,
{
backgroundColor: bgColour,
borderColor: borderColor
}
]}
/>
</MapboxGL.Callout>
</MapboxGL.PointAnnotation>
And stylings
const ANNOTATION_SIZE = 32
const styles = StyleSheet.create({
annotationContainer: {
width: ANNOTATION_SIZE,
height: ANNOTATION_SIZE,
alignItems: 'center',
justifyContent: 'center'
},
annotationFill: {
color: 'black'
},
container: {
flex: 1
},
calloutContainer: {
alignItems: 'center',
justifyContent: 'center',
width: 180,
zIndex: 9999999
},
calloutContent: {
flex: 1,
position: 'relative',
padding: 8,
borderRadius: 3,
borderWidth: 1
},
calloutTitle: {
width: ANNOTATION_SIZE,
height: ANNOTATION_SIZE,
color: 'black',
textAlign: 'center'
},
calloutTip: {
zIndex: 1000,
marginTop: -2,
elevation: 0,
backgroundColor: 'transparent',
borderTopWidth: 16,
borderRightWidth: 8,
borderBottomWidth: 0,
borderLeftWidth: 8,
borderTopColor: 'white',
borderRightColor: 'transparent',
borderBottomColor: 'transparent',
borderLeftColor: 'transparent'
}
})
I am concerned though as well that I should not be using PointAnnotation, as it is marked to be deprecated. Is there an alternative way to achieve the same? Could someone point me into right direction? I am happy to contribute too if needed.

react native, how to make a limited view by another view?

I have this problem and I have not been able to solve it, how can I make view 1 limited by view 2?
I need view 1 not to leave the edges of view 2, the image is on the outside, it should be cropped limited by view 2, I don't know if I make myself understood
<View style={styles.container}>
<View style={styles.progressBar}>
<Animated.View style={[styles.absoluteFill, { borderRadius: 30, backgroundColor: colors.blue2, width }]} />
</View>
<Text style={styles.progressText}>

bottom: 0,
},
progressText: {
position: 'absolute',

},
progressBar: {

thank you
You need to add an overflow: hidden at your progressBar style.
progressBar: {
height: 30,
width: '100%',
overflow: 'hidden',
backgroundColor: colors.blue3,
borderRadius: 30
}
I did this live demo for you:

Scroll doesn't work with ScrollView and absolute positioned component

I have a scrollView and a component with absolute position. The scrollView doesn't scroll at all. Have a look at the code: https://snack.expo.io/#codebyte99/overlap-test
<ScrollView contentContainerStyle={{ flex: 1 }}>
<View style={styles.container}>
<Image
source={{
uri: 'https://facebook.github.io/react/logo-og.png',
cache: 'only-if-cached',
}}
style={{width: 400, height: 100}}
/>
<View style={styles.overlap}>
<Text>Event1</Text>
<Text>Event2</Text>
<Text>Event3</Text>
<Text>Event4</Text>
<Text>Event5</Text>
<Text>Event6</Text>
<Text>Event7</Text>
<View style={{ backgroundColor: 'orange', height: 800, width: 500 }}/>
<View style={{ backgroundColor: 'green', height: 800, width: 500 }}/>
</View>
</View>
</ScrollView>
const styles = StyleSheet.create({
container: {
flex: 1,
alignItems: 'center',
paddingTop: Constants.statusBarHeight,
backgroundColor: '#ecf0f1',
padding: 8,
},
overlap: {
width: 300,
backgroundColor: 'red',
borderColor: 'red',
borderWidth: 1,
position: 'absolute',
top: 80,
zIndex: 9999,
overflow: 'visible'
},
});
If the flex is not used in scrollView, the absolute positioned component are not visible completely and if it is used, the scroll doesn't work.
With flex: 1, the ScrollView container takes all available space, however this does not include the items positioned absolutely inside it since they are out of the document flow.
So you should remove it, and instead you should give the container style enough height to display every item inside:
container: {
flex: 0,
alignItems: 'center',
paddingTop: Constants.statusBarHeight,
backgroundColor: '#ecf0f1',
padding: 8,
height: 2000,
},
Did you try to change flex: 1 to flexGrow: 1 in contentContainerStyle.

Reat Native - position absolute not show on top of View

I use React Native 0.55, and I want to display a kind of icon on top of a , like this : http://b3.ms/qpknagGre9BR
For now, I use this :
<View style={styles.cardContainer}>
<Image source={iconPlayers} style={styles.iconTop} />
<View style={styles.cardBox}>
<View style={styles.container}>
<Text style={styles.txtTitle}>
My title
</Text>
</View>
</View>
</View>
And my styles :
cardBox: {
borderRadius: 20,
backgroundColor: "#FFF",
padding: 5,
marginBottom: 10,
borderColor: "#DDD",
elevation: 4,
paddingTop: 40,
},
cardContainer: {
marginTop: 40,
},
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center'
},
txtTitle: {
color: "#000",
textAlign: "center",
fontWeight: "bold",
},
iconTop: {
width: 60,
height: 60,
zIndex: 999,
position: "absolute",
top: -30,
elevation: 4,
alignSelf: "center",
},
It's crazy because now it works, but I have a problem, I can't put elevation: 4 on styles for an <Image /> element, I have a Warning.
If I remove the elevation: 4, of my styles, the image is shown behind the cardBox.
How can I achieve what I want without any warning ... ? Thanks.
** EDIT **
I wrapper the <Image /> in a <View />, and I put elevation property to the wrapper, and it works.
I thought elevation was for boxShadow for android, but it impacts the zIndex.
I am trying your code in snack expo, which uses the latest react-native version (55.4). There is no warning in applying elevation to Image property, it just works fine and the image is also above the card. If your react-native version gives warning just wrap it in a View and apply elevation to that View. Also, remember zIndex gets affected by your Views elevation (only Android). Since you have applied elevation: 4 to card box, you must give elevation >= 4 for your Image component else it will draw beneath the card box.
snack example: https://snack.expo.io/B14UPA9Bm
You can also avoid Zindex by changing the order of components,
// Render the image component after your card box this way you can avoid setting the zIndex
<View style={styles.cardContainer}>
<View style={styles.cardBox}>
<View style={styles.container}>
<Text style={styles.txtTitle}>
My title
</Text>
</View>
</View>
<Image source={iconPlayers} style={styles.iconTop} />
</View>
cardBox: {
borderRadius: 20,
backgroundColor: "#FFF",
padding: 5,
marginBottom: 10,
borderColor: "#DDD",
elevation: 4,
paddingTop: 40,
},
cardContainer: {
marginTop: 40,
},
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center'
},
txtTitle: {
color: "#000",
textAlign: "center",
fontWeight: "bold",
},
iconTop: {
width: 60,
height: 60,
//zIndex: 999, not required now
position: "absolute",
top: -30,
elevation: 4,
alignSelf: "center",
},
Check and tell if it works in Android and iOS. thanks

Vertical centering in React Native doesn't work

I use a ScrollView and I am not able to center an icon in one of inner Views.
import Icon from 'react-native-vector-icons/MaterialCommunityIcons';
<ScrollView>
...
<View style={styles.detailRowContainer}>
<View style={{flex: 1}}>
<Text style={styles.label} numberOfLines={1}>
{'Phone Number'}
</Text>
<Text style={styles.value} numberOfLines={1}>
{phone}
</Text>
</View>
<View style={styles.round}>
<TouchableWithoutFeedback onPress={this._onPressPhone}>
<Icon size={22} name="phone" />
</TouchableWithoutFeedback>
</View>
</View>;
...
</ScrollView>
detailRowContainer: {
flexDirection: 'row',
justifyContent: 'center',
flex: 1,
marginTop: 10,
paddingBottom: 10,
borderBottomWidth: 1,
borderBottomColor: Colors.lightGray,
},
label: {
color: Colors.glofoxDark,
marginBottom: 3,
},
value: {
color: Colors.glofoxDark,
fontWeight: '800',
borderBottomWidth: 1,
borderBottomColor: Colors.lightGray,
},
round: {
backgroundColor: Colors.lightBlue,
width: 30,
height: 30,
borderRadius: 30,
overflow: 'hidden',
justifyContent: 'center',
alignItems: 'flex-end',
flexDirection: 'row',
padding: 4,
},
The styles need to be modified in this way.
Right now you're doing
flexDirection: row along justifyContent: center. Since your first child element is taking complete parent flex, therefore it does not show its effect
paddingBottom is given but , for centering an equivalent paddingTop must be given
padding for the round style should be replaced with margin, otherwise it affects the position of the inner elements
alignItems in round , must not be flex-end, it should be replaced with center
Here are the styles that will fix the vertical centering
detailRowContainer: {
flexDirection: 'row',
alignItems: 'center',
flex: 1,
marginTop: 10,
paddingTop: 10,
paddingBottom: 10,
borderBottomWidth: 1,
borderBottomColor: Colors.lightGray,
},
round: {
backgroundColor: Colors.lightBlue,
width: 30,
height: 30,
borderRadius: 30,
overflow: 'hidden',
justifyContent: 'center',
alignItems: 'center',
margin: 4
},
