The problem is the Card View is not showing. I tried to apply it with index and position but nothing works. I need other's perspective. Thank you.
This is what I want to achieve:
Here are my codes:
return(
<View style={styles.container}>
{/* <StatusBar backgroundColor={'transparent'} translucent={true}/> */}
<MapView
style={styles.map}
initialRegion={this.state.focusedLocation}
onPress={this.pickLocationHandler}
showsUserLocation={true}
ref={ref => this.map = ref} //For animating map movement
>
{userMarker}
{this.state.markers.map((marker, index) => {
const scaleStyle = {
transform: [
{
scale: interpolations[index].scale,
},
],
};
const opacityStyle = {
opacity: interpolations[index].opacity,
};
return (
<MapView.Marker key={index} coordinate={marker.coordinate}>
<Animated.View style={[styles.markerWrap, opacityStyle]}>
<Animated.View style={[styles.ring, scaleStyle]}/>
<View style={styles.marker}/>
</Animated.View>
</MapView.Marker>
);
})}
</MapView>
<Animated.ScrollView
horizontal={true}
scrollEventThrottle={1}
pagingEnabled={true}
showsHorizontalScrollIndicator={false}
snapToInterval={CARD_WIDTH}
onScroll={Animated.event(
[
{
nativeEvent: {
contentOffset: {
x: this.animation,
},
},
},
],
{ useNativeDriver: true }
)}
style={styles.scrollView}
contentContainerStyle={styles.endPadding}
>
{this.state.markers.map((marker, index) => {
<View style={styles.card} key={index}>
<Image
source={marker.image}
style={styles.cardImage}
resizeMode="cover"
/>
<View style={styles.textContent}>
<Text numberOfLines={1} style={styles.cardtitle}>{marker.title}</Text>
<Text numberOfLines={1} style={styles.cardDescription}>
{marker.description}
</Text>
</View>
</View>
})}
</Animated.ScrollView>
{/* <TouchableOpacity onPress={this.getLocationHandler} style={styles.iconContainer}>
<Icon name="md-locate" size={30} color="blue"/>
</TouchableOpacity> */}
</View>
);
For the StyleSheet:
const styles = StyleSheet.create({
container: {
alignItems: 'center',
},
map: {
height: '100%',
width: '100%'
},
iconContainer: {
position: 'absolute',
top: 60,
right: 15,
zIndex: 1
},
//--- Style for Marker -----//
markerWrap: {
alignItems: 'center',
justifyContent: 'center',
},
marker: {
width: 8,
height: 8,
borderRadius: 4,
backgroundColor: "rgba(130,4,150, 0.9)",
},
ring: {
width: 24,
height: 24,
borderRadius: 12,
backgroundColor: "rgba(130,4,150, 0.3)",
position: "absolute",
borderWidth: 1,
borderColor: "rgba(130,4,150, 0.5)",
},
scrollView: {
position: "absolute",
bottom: 30,
left: 0,
right: 0,
paddingVertical: 10,
},
endPadding: {
paddingRight: width - CARD_WIDTH,
},
card: {
padding: 10,
elevation: 2,
backgroundColor: "#FFF",
marginHorizontal: 10,
shadowColor: "#000",
shadowRadius: 5,
shadowOpacity: 0.3,
shadowOffset: { x: 2, y: -2 },
height: CARD_HEIGHT,
width: CARD_WIDTH,
overflow: "hidden",
},
cardImage: {
flex: 3,
width: "100%",
height: "100%",
alignSelf: "center",
},
textContent: {
flex: 1,
},
cardTitle: {
fontSize: 12,
marginTop: 5,
fontWeight: "bold",
},
cardDescription: {
fontSize: 12,
color: "#444",
}
})
Try using these styles:
container: {
flex: 1
},
map: {
flex: 1,
...StyleSheet.absoluteFillObject,
top: 0, left: 0, right: 0, bottom: 25
},
scrollView: { // Or for a simple View or Card
// ...
position: 'absolute',
bottom: 0,
zIndex: 100,
}

I have built an animated search bar in react native just like search bar of facebook mobile application. The search bar opens up when the search button is clicked on the header. It currently takes same height as the custom header that it is being rendered on. But i want to increase the height of the header to half the screen size when the search bar is on focus and set the height to default when the search bar is not focused. I have tried using my own logic but the problem was when i increased the height the contents of headers were shown below the search bar. And i dont want that. Can anyone help me how to resolve this?

I have spent hours trying to understand why my flat list refuses to scroll. I have see many solutions about adding "flexGrow: 1" to the contentContainerStyle prop of the list, sadly that doesnt solve for me here.

How can I achieve this in react native?

i hope this will help you.
Here is 2 solution according to your requirement.
If you want this type of design without selection then this code will help you :
https://github.com/alex-melnyk/clipped-tabbar
And if you need on each tab selection then here is other easy library for you :
https://github.com/Jm-Zion/rn-wave-bottom-bar
It's not obvious that this can be done with only <View/> components. I would split the TabBar into a flex row container with three subviews, and create an SVG with the filled inverted radius to be used in the center subview. To render the SVG, use react-native-svg. See a rough layout below:
...
import { SvgXml } from 'react-native-svg';
import TabCenterSvg from ‘assets/my-svg.svg’
export default class TabBar extends Component {
render() {
return (
<View style={styles.tabBar}>
<View style={styles.leftContainer}>

Use this library's code and customize according to your UI

Note: I'll not recommend this library as there are low weekly downloads.
Rather than using the whole library, you can use its code.
Hey i am trying to render some cards like tinder so it works but only when i use data that is already in the project, when i try to use data that i get from firebase is don't show up cause it render the cards before getting the data from firebase so how can i do it ?
I tried with this.setstate but no changes
i get the data like this and set it in the array
componentWillMount() {
Users = [
]
var query = firebase.database().ref("users").orderByKey();
query.once("value")
.then(function(snapshot) {
snapshot.forEach(function(childSnapshot) {
// key will be "ada" the first time and "alan" the second time
var key = childSnapshot.key;
// childData will be the actual contents of the child
var childData = childSnapshot.val();
Users.push({ id: key, uri: {uri: childData.photo} })
});
});
}
renderUsers = () => {
console.log(Users)
return Users.map((item, i) => {
if (i < this.state.currentIndex) {
return null
}
else if (i == this.state.currentIndex) {
return (
<Animated.View
{...this.PanResponder.panHandlers}
key={item.id} style={[this.rotateAndTranslate, { height: SCREEN_HEIGHT - 120, width: SCREEN_WIDTH, padding: 10, position: 'absolute' }]}>
<Animated.View style={{ opacity: this.likeOpacity, transform: [{ rotate: '-30deg' }], position: 'absolute', top: 50, left: 40, zIndex: 1000 }}>
<Text style={{ borderWidth: 1, borderColor: 'green', color: 'green', fontSize: 32, fontWeight: '800', padding: 10 }}>LIKE</Text>
</Animated.View>
<Animated.View style={{ opacity: this.dislikeOpacity, transform: [{ rotate: '30deg' }], position: 'absolute', top: 50, right: 40, zIndex: 1000 }}>
<Text style={{ borderWidth: 1, borderColor: 'red', color: 'red', fontSize: 32, fontWeight: '800', padding: 10 }}>NOPE</Text>
</Animated.View>
<Image
style={{ flex: 1, height: null, width: null, resizeMode: 'cover', borderRadius: 20 }}
source={item.uri} />
<Text>{item.id}</Text>
</Animated.View>
)
}
else {
return (
<Animated.View
key={item.id} style={[{
opacity: this.nextCardOpacity,
transform: [{ scale: this.nextCardScale }],
height: SCREEN_HEIGHT - 120, width: SCREEN_WIDTH, padding: 10, position: 'absolute'
}]}>
<Animated.View style={{ opacity: 0, transform: [{ rotate: '-30deg' }], position: 'absolute', top: 50, left: 40, zIndex: 1000 }}>
<Text style={{ borderWidth: 1, borderColor: 'green', color: 'green', fontSize: 32, fontWeight: '800', padding: 10 }}>LIKE</Text>
</Animated.View>
<Animated.View style={{ opacity: 0, transform: [{ rotate: '30deg' }], position: 'absolute', top: 50, right: 40, zIndex: 1000 }}>
<Text style={{ borderWidth: 1, borderColor: 'red', color: 'red', fontSize: 32, fontWeight: '800', padding: 10 }}>NOPE</Text>
</Animated.View>
<Image
style={{ flex: 1, height: null, width: null, resizeMode: 'cover', borderRadius: 20 }}
source={item.uri} />
<Text>{item.id}</Text>
</Animated.View>
)
}
}).reverse()
}
this function render the cards
Any async operation takes time until it resolves ... if you want to use setState to solve your issue ... here's how:
state = {
users: null,
};
componentDidMount() {
users = [];
const query = firebase
.database()
.ref('users')
.orderByKey();
query.once('value').then((snapshot) => {
// Here you users are available:
this.setState({ users });
});
}
render() {
const { users } = this.state;
if (!users) return null;
return users.map(...);
}
componentWillMount should not be used anymore
I am able to get it to the center without the mapview but I cant seem to get the image to the center with mapview. anyone able to do it on react native?
render() {
return (
<View style = { styles.container }>
<MapView style = { styles.mapView }></MapView>
<View style = { styles.mapCenterMarkerView }>
<Image style={styles.mapCenterMarker}
source={{uri: this.state.markerIcon}}/>
</View>
);
}
var styles = StyleSheet.create({
container: {
flex: 1,
},
mapView: {
flex: 1
},
mapCenterMarkerView: {
top: 0,
position: 'absolute',
justifyContent: 'center',
alignItems: 'center',
backgroundColor: 'rgba(0,0,0,0)',
},
mapCenterMarker: {
width: 32,
height: 32,
},
});
I was able to get the result you're looking for, but I had to remove the flex styling from the MapView.

It looks like MapView doesn't allow child nodes. There's probably a way to do this without resorting to position: 'absolute' for the MapView but I'd have to play with it some more.
If you're new to flexbox like me, I've found this to be a good resource:
flexboxin5.com
class SampleApp extends React.Component {
render() {
return (
<View style={ styles.container }>
<MapView style={ styles.mapView }></MapView>
<View style={styles.mapCenterMarker} />
</View>
);
}
}
var styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: 'rgba(0,0,0,0)',
},
mapView: {
position: 'absolute',
top: 20,
bottom: 0,
left: 0,
right: 0,
},
mapCenterMarkerView: {
flex: 1,
},
mapCenterMarker: {
width: 32,
height: 32,
backgroundColor: 'black'
},
});
I move the justifyContent: 'center' down from container for it to work. thank to you because i have a inside the .
container: {
flex: 1,
alignItems: 'center',
backgroundColor: 'rgba(0,0,0,0)',
},
mapView: {
position: 'absolute',
top: 0,
bottom: 0,
left: 0,
right: 0,
},
mapCenterMarkerView: {
flex: 1,
justifyContent: 'center',
backgroundColor: 'rgba(0,0,0,0)',
},
mapCenterMarker: {
width: 32,
height: 32,
backgroundColor: 'rgba(0,0,0,0)'
},
