I'm trying to position the callout at the bottom of the screen and have it fixed to this position even though the map is moving? Has anyone had any luck in achieving this with React Native Maps?
All my attempts have not fixed the callout to the bottom of the screen.
The only way I have found is to avoid using the callout component provided by react-native-maps.
Here is the code for the callout:
<Callout
tooltip
style={styles.itemContainer}
>
<CalloutSubview
style={styles.button}
onPress={closeCallout}
>
<Ionicons name="ios-close-circle" size={30} style={styles.icon} />
</CalloutSubview>
<SemiBoldHeadline
fontSize={18}
text={title}
marginTop={0}
marginBottom={4}
marginRight={30}
/>
<BodyText
fontSize={14}
lineHeight={18}
marginRight={30}
>
{editedString}
</BodyText>
<View style={styles.inlineContainer}>
<CalloutSubview onPress={() => RouteService.openMaps(coordinates.latitude, coordinates.longitude, title)}>
<SmallDirectionsButton />
</CalloutSubview>
<CalloutSubview onPress={readMoreFunction}>
<ReadMoreButton
text={'Read More'}
/>
</CalloutSubview>
</View>
</Callout>
Here is the styling of the callout:
const styles = StyleSheet.create({
itemContainer: {
borderRadius: 5,
borderWidth: 1,
borderColor: Colors.borderColor,
width: Layout.window.width - 100,
backgroundColor: Colors.white,
padding: 20,
paddingRight: 25
},
inlineContainer: {
flexDirection: 'row',
flexWrap: 'wrap',
},
button: {
position: 'absolute',
top: 0,
right: 0,
paddingLeft: 10,
paddingRight: 10,
paddingTop: 10,
paddingBottom: 30,
zIndex: 10,
},
icon: {
color: Colors.almostBlack,
opacity: 0.5
}
});
If you need to render custom react components "statically" above the map you shouldn't build it with using the map's callout component. Instead, create a view and position it absolutely above the map component:
<>
<Map .../>
<View style={{ position: "absolute", bottom: "20"}}>
{/* Your custom view content goes here*/}
</View>
</>
The callout components are just build to be used directly within the map's context and are expected to move when the map moves.
I'm quite new to react native, I'm trying to understand how I can style two components to intercept with each other. Desirably have one component move behind the other component as if they were layers in Photoshop. I'd like to achieve this so that I can animate the styling of the hidden component to reveal it self on press of a touchable opacity. But i'm fine with the animation, I don't need any help there. I only need direction with how to correctly style a component to hide behind another component.
Here are the two components I'm working with, a text component contained inside a touchable opacity (the text box), and a date of publish text component. Both of which are contained inside a main view component.
<View style={styles.contentContainer}>
<View style={styles.dateContainer}>
<Text style={styles.dateText}>a few seconds ago</Text>
</View>
<TouchableOpacity onPress={() => {}}>
<Text style={styles.item}>this is some text input</Text>
</TouchableOpacity>
</View>
const styles = StyleSheet.create({
contentContainer: {
flex: 1,
},
item: {
padding: 16,
fontWeight: 'bold',
borderColor: '#bbb',
borderWidth: 1,
borderStyle: 'solid',
borderRadius: 10,
},
dateContainer: {
flex: 1,
paddingHorizontal: 2,
marginTop: 16,
alignSelf: 'flex-end',
},
dateText: {
color: '#adadad',
},
});
You can use the position:'absolute' and the zIndex in styles to have the layers for views.
The below style would place the dateContainer above the text component and in the corner of the text compoment. You can position the view using left,right,top or bottom.
dateContainer: {
position: 'absolute',
flex: 1,
paddingHorizontal: 2,
top: 30,
alignSelf: 'flex-end',
zIndex: 1000,
},
I'm trying to wrap my head around flexbox, and also how the component tree works with a react-native-maps MapView (and whether that's different from other components with components "on top of them" for which I'm currently using Callout.
For example, here's my MapView's render method. The TouchableOpacity area (and its buttonCallout container. is currently just for my experiments in understanding layout. I'm using the F8StyleSheet wrapper from makeitopen.com
render() {
return (
<View style={styles.container}>
<MapView
style={{ flex: 1 }}
region={this.state.region}
showsUserLocation={true}
>
{this.renderMarkers()}
</MapView>
<Callout style={styles.searchCallout}>
<TextInput
onChangeText={searchText => this.setState({ searchText })}
onSubmitEditing={this.handleSearch.bind(this)}
style={styles.calloutSearch}
placeholder={"Search"}
value={this.state.searchText}
/>
</Callout>
<Callout style={styles.buttonCallout}>
<TouchableOpacity
style={[styles.touchable]}
onPress={() => console.log("press")}
>
<Text style={styles.touchableText}>Press Me 1</Text>
</TouchableOpacity>
<TouchableOpacity
style={[styles.touchable]}
onPress={() => console.log("press")}
>
<Text style={styles.touchableText}>Press Me 2</Text>
</TouchableOpacity>
</Callout>
</View>
);
}
}
const styles = F8StyleSheet.create({
container: {
flex: 1
},
buttonCallout: {
flex: 1,
alignSelf: "flex-end",
justifyContent: "space-between",
backgroundColor: "transparent",
borderWidth: 0.5,
ios: { padding: 5 },
borderRadius: 20
},
touchable: {
backgroundColor: "lightblue",
padding: 10,
margin: 10
},
touchableText: {
fontSize: 24
},
searchCallout: {
flexDirection: "row",
backgroundColor: "rgba(255, 255, 255, 0.9)",
borderRadius: 10,
width: "80%",
marginLeft: "5%",
marginTop: 40
},
calloutSearch: {
borderColor: "transparent",
marginLeft: 10,
width: "90%",
marginRight: 10,
height: 40,
borderWidth: 0.0
}
});
It makes sense how I use margins to get the searchCallout to be where I want it to be because it's at the top.
As the code is now, the buttonCallout (with the TouchableOpacity inside) renders in the top right corner (sensible - alignSelf: 'flex-end' puts it at the "end", on the right).
...
Mid-post update! By changing the styles.container's flexDirection to row, with the buttons callout at alignSelf: flex-end. I've got the button callout on the bottom, and the search callout is still on top. I guess Callout components all render on top of each other.
So now I can use justifyContent on styles.container to have both callouts either in the center or on the left or right (center, flex-start, flex-end). How do I justify the different items separately? (justifySelf is not a thing!)
Wrapping both callouts in a unstyled View component results in the button callout rendering at the top-right but the search callout being nowhere to be found.
Wrapping them both in a callout results in the buttons rendering a little right of the top left corner, with the search callout again not displayed.
Help me understand all this! Thanks :)
if you're trying to position the buttonCallout at the bottom, give it a postion:'absolute', so it will stay at the bottom
buttonCallout: {
flex: 1,
flexDirection:'row',
position:'absolute',
bottom:10,
alignSelf: "center",
justifyContent: "space-between",
backgroundColor: "transparent",
borderWidth: 0.5,
borderRadius: 20
},
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>
