My code is pretty simple: (relevant parts shown only)
<ScrollView style={{/* padding, centering... */}>
<Text>SHARE WITH YOU FRIENDS</Text>
</ScrollView>
Yet, when I inspect the Text node, its width is 100% of its container, and the grey background goes all the width.
Is there a layout setting to make this Text's width as small as possible? I.e. only until the end of the Text.
You can use alignSelf property:
<View style={{alignSelf: 'flex-start'}}>
<Text>SHARE WITH YOU FRIENDS</Text>
</View>
For Scroll view you can try like
<ScrollView contentContainerStyle={{ alignItems: 'flex-start'}}>
<Text >SHARE WITH YOU FRIENDS</Text>
</ScrollView>
Hope this will help!

I have a React page that needs a Scrollview, there's no way around it. The content goes off the bottom of the screen, and it is encapsulated in the ScrollView. I have a red border on the ScrollView element so I can see that it goes past the bottom of the screen where the rest of my content it. However, it just does not want to scroll. I even put an 'onScroll' prop inside with console.log('hit') at one point to see if the ScrollView was even registering my attempts, it was not. This is happening in a couple of similar components, their structure is very similar. The smallest of them looks like this...
<ScrollView style={{borderColor: 'red', borderWidth: 3}}>
<View style={QualityStyles.container}>
<View style={{width: '100%'}}>
<Text style={QualityStyles.leadersTitle}>Top Three Leaders</Text>
</View>
<View style={QualityStyles.topThree}>
{renderTopThree(topThree)}
</View>
<View style={{width: '100%'}}>
<Text style={QualityStyles.leadersTitle}>Employees</Text>
</View>
<View style={QualityStyles.remainders}>
{renderOthers(others)}
</View>
</View>
</ScrollView>
The code's pretty straightforward, with renderTopThree returning 3 components that will take up about 90% of the screen, and renderOthers will fit maybe one component on the screen, and the rest (while rendered and existent) can't be seen since I can't scroll. Anyone see what could be wrong?
I resolved the issue, I had a TouchableWithoutFeedback wrappping the entire Application, and it was blocking out any ability to scroll
I noticed that while adding 'View' with React native, it behaves as if "width: '100%'" was assigned even though I did not enter any style. Same situation exists for any component. It covers the whole area horizontally. What is the cause and solution?
return (
<View style={{flex:1}}>
{/* paints the line he is in full red but should only paint as much as the line of the text */}
<View style={{backgroundColor:'red'}}>
<Text>Example</Text>
</View >
</View>
);
If you want the background color to only encompass the text, you can use this:
<Text style={{backgroundColor: 'red', alignSelf: 'flex-start'}}>
Example
</Text>
I can't seem to manage this simple layout and all the tricks I find for ScrollView don't match my case.
My content has a header and a footer that should "stick" to it.
But when my content becomes too big, the header should be naturally stuck at the top of the screen, the footer at the bottom of the screen, and the middle part is taken by the content which should be scrollable.
Here is the code for the layout and I join some screens.
Red: screen
Blue: content header
Green: content (Scrollview)
Yellow: content footer
<View style={styles.screen}>
<View style={styles.contentHeader}>
{contentHeader}
</View>
<ScrollView style={styles.content}>
{content}
</ScrollView>
<View style={styles.contentFooter}>
{contentFooter}
</View>
</View>
My problem is that the ScrollView should take only the height required by its content but it does not.
Any suggestions ?
You can use FlatList and use its ListFoooterComponent and ListHeaderComponent for rendering your header and footer you can also render these with ScrollView but its recommended to use FlatList for more performant and support.
Have a look at this to FlatList
https://reactnative.dev/docs/flatlist
Otherwise, you can use stickyHeaderIndices prop for rendering header in ScollView and place your footer outside of the ScrollView with these styles.
This will work
<View style={styles.screen}>
<ScrollView style={styles.content} stickyHeaderIndices={[0]}>
<View style={styles.contentHeader}>
{contentHeader}
</View>
{content}
</ScrollView>
<View style={[styles.contentFooter, {position: 'absolute, bottom: 0}]}>
{contentFooter}
</View>
</View>
I'm trying to create an image with a text on it, and in order for the the text to be clearly seen I need to make the image darker.
Also (don't sure if it matters or not) I need the background image to be touchable.
This question was asked several times here and I've seen some answers, but none of them worked for me, so I'm wondering if I'm missing something more crucial here.
My code is the following:
<View style={postStyles.container}>
<TouchableOpacity onPress={() =>
this.props.navigation.navigate('AnotherWindow')}>
<ImageBackground source={require('../../assets/images/my_img.jpg')}
style={{width: '100%', height: 150}}>
<Text style={postStyles.title} numberOfLines={2}>
My text
</Text>
</ImageBackground></TouchableOpacity>
From looking around here, I've tried the following solutions:
Tried to wrap the text element inside the imagebackground tag inside a
View element that has a style property of "backgroundColor" with value of 'rgba(255,0,0,0.5)' (also tried different values),
Tried to add this backgroundColor property to the styles of both the container itself, the TouchableOpacity element
Tried to above two solutions with the "elevation" property instead of backgroundColor (I work in Android).
None of the above solutions worked, in a sense that the background image didn't change at all, so I'm wondering if I'm missing something more crucial.
Thanks!
If anyone still having problems with the ImageBackground component, this is how i solved it, basically i set a view inside the image background which has the backgroundColor that darkens the image.
<ImageBackground
source={Images.background}
style={styles.imageBackground}
>
<View style={styles.innerContainer}>
{content}
</View>
</ImageBackground>
const styles = StyleSheet.create({
imageBackground: {
height: '100%',
width: '100%'
},
innerContainer: {
flex: 1,
backgroundColor: 'rgba(0,0,0, 0.60)'
},
});
if you want to make the image darker, you'll need the Image component and use the tintColor prop like:
<Image source={require('./your_image.png')} style={{ tintColor: 'cyan' }}>
this tintColor prop only works for Image component not ImageBackground, also if you want to add a text on the Image component, you'll need to positioning that text with position: 'absolute' or 'relative'
<View style={postStyles.container}>
<TouchableOpacity
onPress={() => his.props.navigation.navigate('AnotherWindow')}>}
>
<Image
source={require('./my_image.png')}
resizeMode="contain"
style={{ width: '100%', height: 150, tintColor: 'cyan' }}
/>
<Text style={postStyles.title} numberOfLines={2}>
My text
</Text>
</TouchableOpacity>
</View>
Also, if you implement this approach you'll need to calculate the dimensions of the screen for each device, well you'll need to check this other component from react-native: https://facebook.github.io/react-native/docs/dimensions
Please, let me know if this works :D
You should just add tintColor to ImageBackground imageStyle and you're done. easy peasy!
<TouchableOpacity onPress={() => this.props.navigation.navigate('AnotherWindow')}>
<ImageBackground source={require('../../assets/images/my_img.jpg')}
style={{width: '100%', height: 150}}
imageStyle={{tintColor: 'rgba(255,0,0,0.5)'}}>
<Text style={postStyles.title} numberOfLines={2}>
My text
</Text>
</ImageBackground>
</TouchableOpacity>
If I try to scroll to the bottom of my ScrollView, it bounces back to its default position and won't let me view the entirety of its content.
My ( truncated ) setup is fairly simple :
<View>
<View>
<ABunchOfStuff />
</View>
<View style={styles.sectionNode} >
<ABunchOfStuff />
</View>
<ScrollView> <------ My broken ScrollView :(
<View>
<ABunchOfStuff />
</View>
</ScrollView>
</View>
This is a simplified version of my actual code. But I'm reaching the conclusion that there's some kind of "unbounded height" going on as in this reference.
I did try making sure everything and all parents have flex: 1 all the way to the child <View> of my <ScrollView> and up to its parents. But that didn't seem to do the trick.
Any idea on how to debug this? I know ReactNative's website recommends this and says it would be easy to do in the inspector ( but with no instructions on how to do it ). If my assumption that there's an "unbounded height" issue, how would one go about and find this rascal unbounded node? Or is it something else?
Try taking flex out of the ScrollView entirely and just put flex: 1 on the parent. That did the trick for me.
For me the problem was setting a paddingVertical, paddingTop or paddingBottom on the ScrollView. Just don't do that. it influences the height of the content of the ScrollView, without the ScrollView adjusting to it appropriately.
The parent view must have style={{flex: 1}} then the scrollview can have style={{flex: 1}} 🥇
The bounded height thingy means the ScrollView itself must be bound.
If the ScrollView has unbounded height, it will stretch with your content and won't scroll.
You can just add height to the ScrollView and see how this works, from there on you can use absolute height or use flex in a way that will limit the ScrollView height to what you want.
This worked for me:
<View style={{flex: 1}}>
<ScrollView>
<View style={{paddingTop: 16, paddingBottom: 16}}>
<SearchBar />
<ItemsContainer />
</View>
</ScrollView>
</View>
You must make sure that ScrollView has fixed height, either by setting it for parents or for itself.
I use flex to set its height instead of specifying it directly so it works on all screen size. So for your code something like
<View style={{flex: 1}}>
<View>
<ABunchOfStuff />
</View>
<View style={styles.sectionNode} >
<ABunchOfStuff />
</View>
<ScrollView style={{flex:0.8}}>
<View>
<ABunchOfStuff />
</View>
</ScrollView>
</View>
More information in react native docs
This works for me
<ScrollView>
<View style={{height:2000}}>
</View>
<ScrollView>
The important thing is to put a defined height for the elements that are inside the ScrollView
<ScrollView style={{flex: 1, marginBottom: 30}} />
items
</ScrollView>
What worked for me was to wrap the ScrollView in View. Then giving the View a height and setting flex : 1 on ScrollView.
Something like this:
<View style={{ height: "60%" }}>
<ScrollView style={{ flex: 1 }}>
<List/>
</ScrollView>
</View>
The suggested answers above with parent flex: 1 and child flex: 1 work, but this thing was causing my bug.
I had <Image> with percentage height and once I replaced the percentage with a number, it fixed the issue.
this will solve your problem
<ScrollView
contentContainerStyle={{flexGrow:1,justifyContent:'space-
between'}}
>
<The Other Components or Lists/>
</ScrollView>
add <Text></Text>
at the bottom inside scrollview. it will give some space
