I have a modal that I want show when the user clicks a i button.
The modal envelops the entire screen, by setting the position to 'absolute'. This works fine, but when the user clicks somewhere on the screen, it should disappear again.
My TouchAbleWithoutFeedback however, does not register a press. It appears to be having something to do with the position being absolute but I can't put my finger on it.
Also, the clickable elements underneath the modal are still interactable, even though the modal is displayed on top of those elements.
Here is my code:
import { TouchableWithoutFeedback } from 'react-native-gesture-handler';
render()
{
return (<View>
<View style={styles.container}>
<OtherElements/>
</View>
<MainScreenInfoModal showModal={this.state.showInfoModal} />
</View>);
}
const MainScreenInfoModal = ({showModal}) =>
{
if (showModal)
{
return <TouchableWithoutFeedback style={{zIndex: 10}} width={window.width} height={window.height} onPress={() => {console.log('press!')}}>
<View style={styles.infoModal} >
<SvgXml width={300} height={300} xml={mainscreenInfomodal} style={{
alignSelf: 'center',
marginTop: window.height * .45
}}/>
</View>
</TouchableWithoutFeedback>
}
return null;
}
const styles = StyleSheet.create({
container:
{
fontSize: 26,
textAlign: 'center',
display: 'flex',
flexDirection: 'column',
justifyContent: 'flex-start',
alignItems: 'center',
padding: 13,
fontWeight: "bold",
},
{...} ,
infoModal:
{
position: 'absolute',
bottom: 0,
width: window.width,
height: window.height,
backgroundColor: 'rgba(255,255,255,0.7)',
zIndex: 10
}});
try react-native-modalize library, it saved me alot of time and nerves developing modals
I have View with style flex: 1 which contains an image and textbox that are centered on the screen. In android, the view shrinks when the textbox is focused and the keyboard is opened. However, in ios, the size of the view stays the same and the keyboard covers the content.
export default class App extends React.Component { render() {
return (
<View style={styles.container}>
<TextInput style={styles.box}/>
</View>
); }}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
paddingTop: Constants.statusBarHeight,
backgroundColor: '#ecf0f1',
padding: 8,
},
box: {
margin: 24,
fontSize: 18,
fontWeight: 'bold',
textAlign: 'center',
backgroundColor: 'red'
},
});
Created a sample code as above and tested in snack. In the above code, the textbox is not centered when keyboard opened for ios.

Try using <keyboardavoidingview />. Using this component that screen will push itself up once a textinput is focused. Check https://facebook.github.io/react-native/docs/keyboardavoidingview
I just started using react-native so sorry if it's a trivial question.
I'm trying to create a sidebar with multiple links in it. The sidebar works fine but the issue is with the links themselves. Below is the jsx for the link.
<TouchableOpacity style={MenuItemStyles.ItemWrapper} onPress={this.props.onPress}>
<View style={MenuItemStyles.itemIcon}>
<Icon
name={this.props.iconName}
size={this.props.size || 30}
color={Colours.LightGrey}
/>
</View>
<Text style={MenuItemStyles.itemLabel}>
{this.props.label}
</Text>
</TouchableOpacity>
And the style:
const MenuItemStyles = StyleSheet.create({
ItemWrapper: {
flexDirection: 'row',
alignSelf: 'stretch',
marginTop: 10,
width: 100,
marginBottom: 10
},
itemIcon: {
alignItems: 'center',
alignSelf: 'center',
width: 80,
},
itemLabel: {
color: '#000000',
fontSize: 20,
fontFamily: 'sans-serif-light',
textAlign: 'center',
marginLeft: 5,
}
});
The link contains an icon(Material style), follows by the label. The onPress event is registered correctly. However the click area size is very small ie onPress only triggers when pressing on the icon, not the label. I would assume TouchableOpacity covers all nested component?Can I control how wide TouchableOpacity cover?
Thanks
Wrap your <TouchableOpacity/>component in view that has the style you are curenttly assigning on TouchableOpacity like this <View style={MenuItemStyles.ItemWrapper}>
and by adding flex:1 on the <TouchableOpacity/> component it will inherit the size of the <View>
heres a working example of what I think you are trying to accomplish with the solution above implemented:
https://rnplay.org/apps/SW983Q
I have a Touchablehighlight that I need to position absolute, but it becomes unclickable after I do it.
What could cause this? It functions like it should if I dont have the position set to absolute.
Solution was to change the order of the components.
What i originally had:
<TouchableHighLight><Text>Click me</Text></TouchableHighlight>
<View> .... </View>
This was the fix:
<View>...</View>
<TouchableHighLight><Text>Click me</Text></TouchableHighlight>
Dude just go and add zIndex : 1 to the view containing the buttons and boom you are done in most of the cases. Also note adding elevation adds shadow to android button and sometimes elevation may also be a issue if its added to parent and not added to child then the child button may not work.(Rare Case)
eg:
buttonContainers:
{
zIndex: 1,
alignSelf: 'flex-end',
position: 'absolute',
top:5,
right: 5,
height: 40,
borderWidth: 1,
justifyContent: 'center',
alignContent: 'center',
width: 80
},
SOLVED:
I faced this issue today. I have solved it.
Import TouchableOpacity from react-native-gesture-handler instead of react-native.
Before:
import {TouchableOpacity} from "react-native";
After:
import {TouchableOpacity} from 'react-native-gesture-handler'
use onPressIn instead of onPress
That made the area clickable!
I used TouchableOpacity inside an absolute view. The onPress function was not called after press it. But the opacity changed. I've tried all the above solutions, but none works.
My solutions is use onPressIn instead of onPress.
It seems like the inner action of Touchable* is weird in ReactNative when it's in an absolute view.
After trying everything for two hours, the solution I found was to change my button position.
Before ...
export default class Navbar extends Component {
componentDidMount() {
console.log(this.props);
}
render() {
return (
<View style={styles.content}>
<TouchableOpacity
onPress={this.props.openModal}
style={styles.containerButton}
>
<Text>New</Text>
</TouchableOpacity>
<Text style={styles.textCenter}>Remember me</Text>
</View>
);
}
}
const styles = StyleSheet.create({
content: {
paddingTop: 30,
paddingBottom: 10,
backgroundColor: '#81C04D',
flexDirection: 'row'
},
containerButton: {
position: 'absolute',
top: 30,
left: 8
},
textCenter: {
flex: 1,
textAlign: 'center',
fontWeight: 'bold'
}
});
After ...
export default class Navbar extends Component {
componentDidMount() {
console.log(this.props);
}
render() {
return (
<View style={styles.content}>
<Text style={styles.textCenter}>Remember me</Text>
<TouchableOpacity
onPress={this.props.openModal}
style={styles.containerButton}
>
<Text>New</Text>
</TouchableOpacity>
</View>
);
}
}
const styles = StyleSheet.create({
content: {
paddingTop: 30,
paddingBottom: 10,
backgroundColor: '#81C04D',
flexDirection: 'row'
},
containerButton: {
position: 'absolute',
top: 30,
left: 8
},
textCenter: {
flex: 1,
textAlign: 'center',
fontWeight: 'bold'
}
});
It works!!!
My solutions is:
style:{
zIndex: 1,
position: 'absolute',
}
use
zIndex: 1 in view, it'll work.
<View style={{position : 'absolute', marginTop : 25, zIndex: 1}}>
More details can be found here :
How to use zIndex in react-native
For me, it works like:
import { TouchableOpacity } from 'react-native';
onPress, zIndex: 1, position: 'absolute'
One more solution.....
For me what worked was a combination of things....
import { TouchableOpacity } from 'react-native-gesture-handler'
and I WRAPPED my TouchableOpacity in a View.
before:
<TouchableOpacity onPress={()=> addCallback()}
style={styles.addButtonHolder}
>
<PlusCircle style={styles.addButton} width={70} height={70} stroke={"white"} strokeWidth={3}/>
</TouchableOpacity>
after:
<View style={styles.addButtonHolder}>
<TouchableOpacity onPress={()=> addCallback()}>
<PlusCircle style={styles.addButton} width={70} height={70} stroke={"white"} strokeWidth={3}/>
</TouchableOpacity>
</View>
StyleSheet:
const styles = StyleSheet.create({
addButtonHolder: {
position: 'absolute',
bottom: 70,
right: 10,
justifyContent: 'center',
alignItems: 'center',
zIndex: 1,
},
addButton: {
backgroundColor: '#b4cffa',
borderRadius: 35
}
})
This worked for me
import { TouchableOpacity } from 'react-native-gesture-handler'
and changed onPress to onPressIn
<TouchableOpacity onPressIn={() => console.log('clicked')}></TouchableOpacity>
My solution was to import TouchableHighlight from 'react-native'
It was originally imported from 'react-native-gesture-handler'
This props help to disable ScrollView to catch all touches and let child handles
keyboardShouldPersistTaps='always'
'always', the keyboard will not dismiss automatically, and the scroll view will not catch taps, but children of the scroll view can catch taps.
'handled', the keyboard will not dismiss automatically when the tap was handled by children of the scroll view (or captured by an ancestor).
https://reactnative.dev/docs/scrollview#keyboardshouldpersisttaps
When the position is absolute, TouchableHighlight or TouchableOpacity goes beneath from the surface. You have to add a higher zIndex value to the Container.
He guy, I took a long time to find out why this happens.
I tested a lot of the solution here. Two things worked for:
The first answer here
The second one is to add elevation and zIndex on the wrapper container
<View style={{ zIndex:0 }>
...
<View style={{ position: 'absulote', zIndex:10 ,elevation: 10 }}>
<TouchableHighLight><Text>Click me</Text></TouchableHighlight>
</View>
<View> .... </View>
...
</View>
If I am right, the reason for that is even that the button is shown, Android treats differently the layers of the Press events and you need to set a low level for the rest of your components. Defining a lower level for your wrapper component, all its children without this attribute will automatically inherit from the parent.
My problem was quite different, a backgroundColor style property was set on the container of my button. The color didn't work. I missed to remove this useless property. Finally, this backgroundColor was making an invisible sheet above my button. Removing it make it clickable again.
I faced the problem only on Android.
Add a zIndex to the component where you added position absolute. This solved the issue for me.
position: 'absolute',
zIndex: 1,
`
I ran into a similar problem, what I did was, I enclosed the whole thing into a new View and instead of giving 'absolute' position to
the TouchableOpacity, I gave it to the parent View. That made the
Opacity again clickable somehow. Here is the code snippet of before
and after
My Code before
<TouchableOpacity
onPress={() => {
console.log("hah");
}}
style={{
height: 50, width: 50,
backgroundColor: 'rgb(90,135,235)',
borderRadius: 25, alignItems: 'center',
justifyContent: 'center', right: 0,position:'absolute'
}}>
<Image source={require('../assets/images/element-acorn-white.webp')}
style={{ height: 30, width: 30, resizeMode: 'contain' }} />
</TouchableOpacity>
After Wrapping into a View with 'absolute'
<View style={{
alignItems: 'flex-end', position: 'absolute',
bottom: Dimensions.get('screen').height / 5
}}>
<TouchableOpacity
onPress={() => {
console.log("hah");
}}
style={{
height: 50, width: 50,
backgroundColor: 'rgb(90,135,235)',
borderRadius: 25, alignItems: 'center',
justifyContent: 'center', right: 0,
}}>
<Image source={require('../assets/images/element-acorn-white.webp')}
style={{ height: 30, width: 30, resizeMode: 'contain' }} />
</TouchableOpacity>
</View>
I'd like to use a background image in my react native app,
the image is smaller than the screen, so I have to stretch it.
but it doesn't work if the image is loaded from asset bundle
var styles = StyleSheet.create({
bgImage: {
flex: 1,
flexDirection: 'row',
justifyContent: 'center',
alignItems: 'stretch',
resizeMode: 'stretch',
},
welcome: {
fontSize: 20,
textAlign: 'center',
margin: 10,
}
});
<Image source={require('image!background')} style={styles.bgImage}>
<Text style={styles.welcome}>
Welcome to React Native!
</Text>
</Image>
it looks like this:
however, it works fine for a remote image, through source={{uri: 'background-image-uri'}}:
From Github issue: Image {require} is broken in React Native for Resizing, you could try <Image style={{width: null, height: null}}, hope that facebook would fix it soon.
The Image tag should generally not be treated as a container view.
Having an absolutely positioned wrapper containing your (stretched/contained) image appears to work well:
var styles = StyleSheet.create({
bgImageWrapper: {
position: 'absolute',
top: 0, bottom: 0, left: 0, right: 0
},
bgImage: {
flex: 1,
resizeMode: "stretch"
},
welcome: {
fontSize: 20,
textAlign: 'center',
margin: 10
}
});
<View style={{ flex: 1 }}>
<View style={styles.bgImageWrapper}>
<Image source={require('image!background')} style={styles.bgImage} />
</View>
<Text style={styles.welcome}>
Welcome to React Native!
</Text>
</View>
You could always use the Dimensions module to get the width of the screen and set your image's width style to that value:
var Dimensions = require('Dimensions');
var {width, height} = Dimensions.get('window');
It also seems strange that a remote image works fine...you can try loading up a local static image with the uri syntax by using source={{uri: 'local_image_file_name' isStatic: true}}.
for me use undefined instead of null value. on typescript environment, it will be prompted not assignable
bgImage: {
flex: 1,
width: undefined,
height: undefined,
resizeMode: 'stretch',
},
