I rendered two similar components. Each component has an icon and text, and each of them should not be overlapping. What's wrong with my styling?
import Icon from "react-native-elements/src/icons/Icon";
<TouchableOpacity onPress={_ => playSound(audio)} style={{
flexDirection: 'row',
flexGrow:1,
flex: 1
}}>
<View>
<Icon name="volume-up" color={PRIMARY_BG} size={24}/>
</View>
<View>
<Text style={{
flexGrow: 1,
fontSize: 8,
backgroundColor: GRAY
}}>
[{locale}]{this.props.pronunciation[locale][0]}
</Text>
</View>
</TouchableOpacity>
Here's the output:
Parent container style
headItemContent: {
flex: 3,
flexDirection: 'row',
justifyContent: 'space-between'
},
I am not sure where your images are meant to be, but the problem is the flexDirection you have set. The flexDirection on the touchableOpacity should be column:
flexDirection: "column"
Since yours is row, the images and text are rendering beside each other. There is not enough space so they are over lapping. So change the flexDirection and that should fix it.
Edit - Or add flex to your image and text:
<View style={{flex: 1}}>
<Icon name="volume-up" color={PRIMARY_BG} size={24}/>
</View>
<View style={{flex: 1}}>
<Text style={{
flexGrow: 1,
fontSize: 8,
backgroundColor: GRAY
}}>
[{locale}]{this.props.pronunciation[locale][0]}
</Text>
</View>
Let me know if that helps!

With react-native for windows UWP I have the following JSX:
<View style={{ flexDirection: "row" }}>
<View style={{ flex: 1, flexDirection: 'column', margin: 5, alignItems: 'stretch' }}>
<View style={{ flexDirection: 'row' }}>
<Text selectable={true} style={{ textAlign: 'right', flex: 1 }}>Average:</Text>
<Text selectable={true} style={{ flex: 2 }} > {this.props.averageValue} C</Text>
</View>
<View style={{ flexDirection: 'row' }}>
<Text selectable={true} style={{ textAlign: 'right', flex: 1 }}>Last:</Text>
<Text selectable={true} style={{ flex: 2 }}> {this.props.lastValue} C</Text>
</View>
</View>
</View>
Which lays out the Average and Last text so they're aligned with the colons like so:
Visually this is what I want, but I can't select the text of an entire line at once. Only each individual text element is selectable. If I wrap the two text blocks with an outer text block like this:
<View style={{ flexDirection: 'row' }}>
<Text selectable={true}>
<Text style={{ textAlign: 'right', flex: 1 }}>Average:</Text>
<Text style={{ flex: 2 }} > {this.props.averageValue} C</Text>
</Text>
</View>
<View style={{ flexDirection: 'row' }}>
<Text selectable={true}>
<Text style={{ textAlign: 'right', flex: 1 }}>Last:</Text>
<Text style={{ flex: 2 }}> {this.props.lastValue} C</Text>
</Text>
</View>
Then my text is selectable like I want, but the layout changes to this:
How can I get the layout I want and all of the text to be selectable? Do I have to use explicit widths or can this be done with flexbox?
This doesn't appear to be possible. The only way to make them all selectable is to wrap them in an outer Text element. However text boxes do not participate in Flexbox layout so the alignment I want cannot be achieved.
I have a very basic styling question in react native
below is my code:
[![return (
<View style={{ flex: 1, backgroundColor: "blue" }}>
<ScrollView style={{ flex: 1, backgroundColor: "blue" }}>
<View style={{ flex: 1, backgroundColor: "red" }}>
<Text>Hello</Text>
</View>
<View style={{ flex: 1, backgroundColor: "orange" }}>
<Text>Hello</Text>
</View>
<View style={{ flex: 1, backgroundColor: "green" }}>
<Text>Hello</Text>
</View>
</ScrollView>
<ScrollView style={{ flex: 1, backgroundColor: "blue" }}>
<View style={{ flex: 1, backgroundColor: "red" }}>
<Text>Hello</Text>
</View>
<View style={{ flex: 1, backgroundColor: "orange" }}>
<Text>Hello</Text>
</View>
<View style={{ flex: 1, backgroundColor: "green" }}>
<Text>Hello</Text>
</View>
</ScrollView>
</View>
);
I just want to know why am I getting blue space between 2 ScrollVie? If I remove ScrollView then my flex property is working fine.
Change your ScrollView to:
<ScrollView
... other stuff
// Add here
contentContainerStyle={{
flex: 1 // or flexGrow: 1
}}
>
Issue on React Native repo
The styles you are passings to the ScrollView should be passed in the ScrollView Container
like this
<ScrollView
contentContainerStyle={{
flex: 1 // or flexGrow: 1
}}
> ... </ScrollView >
this can help you to understand
The reason is that you are giving flex:1 for the parent view So it takes a maximum screen height. And also the child ScrollViews has flex: 1. If you change the background color of the scroll view to some other color you can notice that it is the scrollView that is stretched and not the Parent View.
You can remove the flex property of the parent view so that your ScrollView will not be stretched to take up half the screen.
I have this view, where there are two Views in a column:
<View style={styles.container}>
<View style={styles.content}>
<View style={{backgroundColor: 'orange'}}>
<Text>Test</Text>
</View>
<View style={{backgroundColor: 'yellow'}}>
<Text>Test2</Text>
</View>
</View>
</View>
This is my Styles:
container: {
flexDirection: 'row',
backgroundColor: 'white',
justifyContent:'center',
alignItems:'center',
height: 80,
margin: 8,
},
content: {
flex:1,
alignItems: 'stretch',
flexDirection: 'column',
},
Here is a ScreenShot of what it looks with the above code.
How can I get the orange and yellow View to expand vertically equally, without manually defining the height for each of them?
The Text inside should be centered, but left-aligned.
Add flex: 1 to each cell to make them expand and add justifyContent: 'center' to make the text vertically centered. Like this:
<View style={styles.container}>
<View style={styles.content}>
<View style={{ backgroundColor: 'orange', flex: 1, justifyContent: 'center' }}>
<Text>Test</Text>
</View>
<View style={{ backgroundColor: 'yellow', flex: 1, justifyContent: 'center' }}>
<Text>Test2</Text>
</View>
</View>
</View>

I'm having a problem positioning the white floating button on top of the blue header. The button is a TouchableOpacity inside a View which has Header and a ScrollView. How do I position the button on top of the blue header and scrollview?
<View style={{ flex: 1 }}>
<Header headerText={'Events'} />
<TouchableOpacity
style={styles.addButtonContainerStyle}
onPress={ () => {Actions.addEventMain()} }
>
<Text style={styles.addButtonTextStyle}>+</Text>
</TouchableOpacity>
<EventList />
</View>
Below code would help. Absolute position of views sometimes becomes hard to maintain when code grows. You need to customise below code as per your need.
<View style={{ backgroundColor: "blue", flexDirection: "row-reverse" }}>
<TouchableOpacity style={{ alignSelf: "flex-end" }}>
<Text style={{ justifyContent: "center", fontSize: 20, textAlign: 'center' }}>
+
</Text>
</TouchableOpacity >
<View style={{ flex: 1 }}>
<Text style={{ alignSelf: "center", fontSize: 20, textAlign: 'center' }}>
Event
</Text>
</View>
</View >
So for the above image, I am attempting to get the "green" box to wrap around the dynamic text. Notice how the blue and yellow text boxes are in a flex: 'row' configuration, and the blue box of text is at a flex: 2 and the yellow is flex: 1.
Things work fine until the text is too big for the parent container.
I'd like for the green container to grow as needed to fit the flexed inner children. Is this possible with react native?
Here's an image of what it looks like in a web sense:
I've tried setting the green box to have a flex: 1 but then it's way too big as it fills the entire screen. Setting height is possible, but I don't know the size of the biggest inner component (at least without some hackery). I've even tried minHeight.
Has anyone attempted something like this? Do I need to get the height of the inner elements dynamically myself?
UPDATE - Here's the bit of code:
<View style={{ flex: 1, flexDirection: 'column', marginTop: 70, backgroundColor: '#f9e2ff' }}>
<View
style={{
minHeight: 40,
borderWidth: 1,
borderStyle: 'solid',
padding: 5,
margin: 5,
backgroundColor: '#58c09e'
}}
>
<View style={{ flex: 1, flexDirection: 'row' }}>
<View style={{ flex: 2, backgroundColor: '#eeff96' }}>
<Text>
Hello this is a long bit of text that will fill up the entire column to see how the text will wrap
</Text>
</View>
<View style={{ flex: 1, backgroundColor: '#eeffff' }}>
<Text>Hello again?</Text>
</View>
</View>
</View>
</View>
Thanks for looking.
Ok after looking around a bit more and reading: flex vs flexGrow vs flexShrink vs flexBasis in React Native? I was able to figure out the problem.
What I needed was flex: 0 on the row:
<View style={{ flex: 1, flexDirection: 'column', marginTop: 70, backgroundColor: '#f9e2ff' }}>
<View
style={{
minHeight: 40,
borderWidth: 1,
borderStyle: 'solid',
padding: 5,
margin: 5,
backgroundColor: '#58c09e'
}}
>
<View style={{ flex: 0, flexDirection: 'row' }}>
<View style={{ flex: 2, backgroundColor: '#eeff96' }}>
<Text>
Hello this is a long bit of text that will fill up the entire column to see how the text will wrap
</Text>
</View>
<View style={{ flex: 1, backgroundColor: '#eeffff' }}>
<Text>Hello again?</Text>
</View>
</View>
<View>
<Text>Here's another test</Text>
</View>
</View>
</View>
This produces what I would expect:
So I guess the flexbox doesn't "work[s] the same way in React Native as it does in CSS on the web" like they state in their documentation.
Try This Coode -->
<View style={{flex:1,flexDirection:'row',borderWidth:1,padding:5}}>
<View style={{flex:0.7}}>
<Text>
Hello This is long bit of text that will fill up the entire
column to see how the text will wrap
</Text>
</View>
<View style={{flex:0.3}}>
<Text>Hello Again</Text>
</View>
</View>
