and this is the EventBannerSheet Component, I got this BottomSheet library and wrote it, but the onPress function doesn't work here. Also I did it before using the Checkbox library but onValueChange also didn't work in android.
import React, { useRef } from "react"
import { StyleSheet, Text, View, Image, TouchableOpacity } from "react-native"
import BottomSheet from "reanimated-bottom-sheet"
const EventBannerSheet: React.FC = () => {

const consoleHello = () => {
console.log("helloooooooo!!!!")
}
const renderContent = () => (
<View style={styles.bottomSheet}>
<View style={styles.sheetTextContainer}>

style={styles.sheetText}
onPress={() => {
consoleHello()

<View style={styles.sheetCloseContainer}>

<TouchableOpacity onPress={() => sheetRef.current.snapTo(2)}>

</View>
)
return (
<>
<BottomSheet
initialSnap={1}
ref={sheetRef}
snapPoints={[450, 350, 0]}
borderRadius={10}
renderContent={renderContent}
/>
</>
)
}
and this is stylesheet of EventBannerSheet
const styles = StyleSheet.create({
bottomSheet: {
backgroundColor: "white",
padding: 25,
height: 440,
},
sheetTextContainer: {
height: 270,
alignItems: "center",
justifyContent: "center",
backgroundColor: "#d3d3d3",
borderRadius: 10,
},
sheetText: {
fontSize: 30,
color: "white",
},
sheetCloseContainer: {
flexDirection: "row",
justifyContent: "space-between",
marginTop: 20,
},
})
<View style={styles.bottomSheet}>
<View style={styles.sheetTextContainer}>
<TouchableOpacity
style={styles.sheetText}
onPress={() => {
consoleHello()
}}
>
<Text style={{ color: "black" }}>EVENT BANNER</Text>
</TouchableOpacity>
<Text style={styles.sheetText}>IMG</Text>
</View>
<View style={styles.sheetCloseContainer}>

</TouchableOpacity>
<TouchableOpacity onPress={() => sheetRef.current.snapTo(2)}>
<Text>닫기</Text>
</TouchableOpacity>
</View>
</View>
Please try the above code. I have tested the code and touchable opacity is working fine without any issue. I have added a text color for EVENT BANNER text just to test. Let me know if you need any other help.
here is the config I've made to make it work on both iOS and Android with button and horizontal drag slider
<BottomSheet
initialSnap={1}
ref={sheetRef}
snapPoints={[450, 350, 0]}
borderRadius={10}
renderContent={renderContent}
enabledContentGestureInteraction={false}
enabledInnerScrolling={false}
enabledContentTapInteraction={false}
/>
I append three attributes so i solve this problem.
And the button inside the view use TouchableOpacity from RN for iOS and TouchableOpacity from react-native-gesture-handler for Android
I have a textInput. When i click on the textInput, i want "Search Icon" to be passive, but when i dont click on the textInput, i want "Search Icon" to be active,
Its strangely not doing what I want. As I look at my code, it looks correct, but i must have something wrong because it doesnt work as i wanted.(not giving an error tho)

You can use the TextInput component's onFocus, onBlur props to focus information on an input. Sample code is available below.
const [text, setText] = useState("")
const [inputFocus, setFocus] = useState(false)
return (
<View style={styles.container}>
<Text>
{inputFocus ? "Focused" : "Not Focused"}
</Text>
<TextInput
value={text}
onChangeText={setText}
onFocus={() => setFocus(true)}
onBlur={() => setFocus(false)}
style={{
width: "100%",
height: 44,
backgroundColor: "gray"
}}
/>
</View>
)
We created a FlatList component and a Contact screen in our app. We want to add 'heart' icon to the near of the images in Contact screen. We added heart icon near to all of items. But, if we pressed one of these icons, it changes all of theirs colors to red, not only one of them. We want to change the color of clicked item.
Screenshot of our program:
This is our FlatList component:
import React, { Component } from 'react';
import { View, Text, SafeAreaView, StyleSheet, FlatList, Image, TouchableOpacity,
TouchableWithoutFeedback, TextInput } from 'react-native';
import { Right, Icon } from 'native-base';
import data from '../../data';
export default class FlatListComponent extends Component {
state = {
text: '',
contacts: data,
like: false,
color: 'white',
}
toggleLike=()=>{
this.setState({
like: !this.state.like
})
if(this.state.like){
this.setState({
color: 'red',
})
}else{
this.setState({
color: 'white',
})
}
}
renderContactsItem = ({item, index}) => {
return (
<View style={[styles.itemContainer]}>
<Image
style={styles.avatar}
source={{ uri: item.image }} />
<View style={styles.textContainer}>
<Text style={[styles.name], {color: '#fafafa'}}>{item.first_name}</Text>
<Text style={{ color: '#fafafa' }}>{item.last_name}</Text>
</View>
<Right style={{justifyContent: 'center'}}>
<TouchableWithoutFeedback onPress={this.toggleLike}>
{/*{this.like ? (
<Icon name="heart" type='FontAwesome' style={{paddingRight: 10, fontSize: 30, color: 'red'}} />
) :
( <Icon name="heart" type='FontAwesome' style={{paddingRight: 10, fontSize: 30, color: 'white'}} /> )
}*/}
<Icon name='heart' type='FontAwesome' size={32} style={{color: this.state.color === "white" ? 'white' :'red', paddingRight: 10 }}/>
{/*<Icon name="heart" type='FontAwesome' style={{paddingRight: 10, fontSize: 30, color: this.state.color}} />*/}
</TouchableWithoutFeedback>
</Right>
</View>
);
}
searchFilter = text => {
const newData = data.filter(item => {
const listItems = `${item.first_name.toLowerCase()}`
return listItems.indexOf(text.toLowerCase()) > -1;
});
this.setState({
contacts: newData,
});
};
renderHeader = () => {
const {text} = this.state;
return (
<View style={styles.searchContainer}>
<TextInput
onChangeText = {text => {
this.setState ({
text,
});
this.searchFilter(text);
}}
value={text}
placeholder="Search..."
style={styles.searchInput} />
</View>
)
}
render() {
return (
<FlatList
ListHeaderComponent={this.renderHeader()}
renderItem={this.renderContactsItem}
keyExtractor={item => item.id}
data={this.state.contacts}
/>
);
}
}
const styles = StyleSheet.create({
itemContainer: {
flex: 1,
flexDirection: 'row',
paddingVertical: 10,
borderBottomWidth: 1,
borderBottomColor: '#eee'
},
avatar: {
width: 50,
height: 50,
borderRadius: 25,
marginHorizontal: 10,
},
textContainer: {
justifyContent: 'space-around',
},
name: {
fontSize: 16,
},
searchContainer: {
padding: 10
},
searchInput: {
fontSize: 16,
backgroundColor: '#f9f9f9',
padding: 10,
}
});
Our Contact screen is just:
import React from 'react';
import 'SafeAreaView' from 'react-native';
import FlatList from './FlatList';
export default function Contact() {
<SafeAreaView style={{ flex: 1 }}>
<FlatList />
</SafeAreaView>
}
How can we implement this?
I've run into this recently :) One option is to make the renderContactsItem its own component. For example:
const RenderContactsItem = ({item, index}) => {
const [like, setLike] = useState(false);
const [color, setColor] = useState("white");
const toggleLike = () => {
setLike(!like)
if(like) {
setColor("red");
} else {
setColor("white");
}
}
return (
<View style={[styles.itemContainer]}>
<Image
style={styles.avatar}
source={{ uri: item.image }} />
<View style={styles.textContainer}>
<Text style={[styles.name], {color: '#fafafa'}}>{item.first_name}</Text>
<Text style={{ color: '#fafafa' }}>{item.last_name}</Text>
</View>
<Right style={{justifyContent: 'center'}}>
<TouchableWithoutFeedback onPress={toggleLike}>
<Icon name='heart' type='FontAwesome' size={32} style={{color, paddingRight: 10 }}/>
</TouchableWithoutFeedback>
</Right>
</View>
);
}
In this case, each item manages its own state, so setting like doesn't set it for every item.
Another option would be to build an object with "like" states and set the values as the hearts are pressed. For example:
state = {
text: '',
contacts: data,
like: {},
color: 'white', // You don't need this
}
Then, when a heart is pressed, you can send toggleLike the index, and set the state like so:
toggleLike = (index) => {
let newLike = {...this.state.like};
newLike[index] = !Boolean(newLike[index]);
this.setState({
like: newLike,
});
}
And render the color conditionally depending on the index value of the like state, like so:
<Icon name='heart' type='FontAwesome' size={32} style={{color: this.state.like[index] ? 'red' :'white', paddingRight: 10 }}/>
Like in tinder, i have a screen with 3 Image Pickers. When I pick an image from the gallery, I want it to persist inside the TouchableOpacity container. However, the image overlaps the container.
I have been been trying various things mentioned here but the image still overlaps like in the image below:
What is the problem?

correct answer as described here
"However because images will try to set the width and height based on the actual size of the image, you need to override these style properties"
<Image
style={{
flex: 1,
alignSelf: 'stretch',
width: undefined,
height: undefined
}}
source={require('../../assets/images/onboarding-how-it-works.png')}
/>
Instead of calculating image width try this:
<TouchableOpacity
onPress={() => handleChoosePhoto()}
style={styles.button}>
{photo ? (
<View style={styles.photoContainer}>
<Image source={photo} style={styles.photo} />
</View>
) : (
<FontAwesomeIcon
icon={faPlusCircle}
color={Colors.defaultColor}
size={22}
style={styles.icon}
/>
)}
</TouchableOpacity>
const styles = StyleSheet.create({
photoContainer: {
// flex: 1
},
photo: {
height: WIDTH / 2,
width: '100%',
resizeMode: 'contain'
}
});
I prefer ImageBackground instead. Below is the code to achieve you the desired View:
<ImageBackground
imageStyle={styles.image}
style={styles.imageContainer}
source={{uri: this.state.imageUri}}>
<TouchableOpacity onPress={this._pickImage} style={{
height: WIDTH/2,
width: WIDTH/2,
justifyContent: "center",
alignItems: "center"}}>
<Entypo name="camera" color={Colors.GREY} size={35}/>
</TouchableOpacity>
</ImageBackground>
I made a header using react native elements, and I want to add background image into it. Is there anyway to do it?
I am using react-native-elements: "^0.19.1"
Here is my header code
render() {
return (
<View style={{ paddingTop: Constants.statusBarHeight, backgroundColor: color.light_grey }}>
<Header
leftComponent={this.props.left ? this.props.left : <IconWrapper name='menu' color='black' size={28} style={styles.icon} onPress={() => Actions.drawerOpen()} />}
centerComponent={<Text style={styles.headerText}>{this.props.title}</Text>}
rightComponent={this.props.right ? this.props.right : <IconWrapper name='handbag' type='simple-line-icon' color='black' size={28} style={styles.icon} onPress={() => Actions.BagContents()} />}
outerContainerStyles={[styles.headerOuterContainer, { height: 0.08 * windowHeight() }]}
/>
</View>
)
}
}
You can always create your own <Header/> component, probably will take you more time but you will be able to understand it and edit it as you like. I created a simple Header component to show you how you can accomplish adding a background image to your header. See the snack #abranhe/stackoverflow-56729412
Header.js
import React, { Component } from 'react';
import { View, TouchableOpacity, StyleSheet, Dimensions, ImageBackground } from 'react-native';
export default class Header extends Component {
renderContent() {
return (
<View style={styles.content}>
<View style={styles.left}>{this.props.left}</View>
<View style={styles.center}>{this.props.center}</View>
<View style={styles.right}>{this.props.right}</View>
</View>
);
}
renderHeaderWithImage() {
return (
<ImageBackground style={styles.container} source={this.props.imageSource}>
{this.renderContent()}
</ImageBackground>
);
}
renderHeaderWithoutImage() {
return (
<View style={[{ backgroundColor: '#f8f8f8' }, styles.container]}>
{this.renderContent()}
</View>
);
}
render() {
return this.props.image
? this.renderHeaderWithImage()
: this.renderHeaderWithoutImage();
}
}
const styles = StyleSheet.create({
container: {
top: 0,
position: 'absolute',
width: Dimensions.get('window').width,
backgroundColor: '#f8f8f8',
borderBottom: 1,
borderColor: '#f8f8f8',
shadowColor: '#000',
shadowOffset: { width: 0, height: 2 },
shadowOpacity: 0.5,
},
content: {
width: '100%',
flexDirection: 'row',
justifyContent: 'space-between',
alignItems: 'center',
marginTop: Dimensions.get('window').height * 0.03,
height: Dimensions.get('window').height * 0.045,
},
left: {
marginHorizontal: 5,
},
center: {
marginHorizontal: 5,
},
right: {
marginHorizontal: 5,
},
});
and then on when you want to use the Header component you can set the image prop to true, eg:
import React from 'react';
import { Text, View, StyleSheet } from 'react-native';
import { Ionicons } from '#expo/vector-icons';
import Header from './components/Header';
export default () => {
return (
<View>
<Header
image
imageSource={{ uri: 'https://yourimage.png' }}
left={<Ionicons name="md-arrow-round-back" size={25} />}
center={<Text>Projects</Text>}
right={<Ionicons name="ios-camera" size={25} />}
/>
</View>
);
};
and then if you set the image prop to false you will remove the image from the background.
<Header
image={false}
imageSource={{ uri: 'https://yourimage.png' }}
left={<Ionicons name="md-arrow-round-back" size={25} />}
center={<Text>Projects</Text>}
right={<Ionicons name="ios-camera" size={25} />}
/>
There is ReactNative's component ImageBackground you can use it.
like this,
<ImageBackground source={...} style={{width: '100%', height: '100%'}}>
<Header
leftComponent={this.props.left ? this.props.left : <IconWrapper name='menu' color='black' size={28} style={styles.icon} onPress={() => Actions.drawerOpen()} />}
centerComponent={<Text style={styles.headerText}>{this.props.title}</Text>}
rightComponent={this.props.right ? this.props.right : <IconWrapper name='handbag' type='simple-line-icon' color='black' size={28} style={styles.icon} onPress={() => Actions.BagContents()} />}
outerContainerStyles={[styles.headerOuterContainer, { height: 0.08 * windowHeight() }]}
/>
</ImageBackground>
You can always style it your way.
assuming you are using react-navigation
You need to add a custon header component in navigationOptions,
import { Header } from 'react-navigation';
static navigationOptions = ({ navigation }) => {
return {
header: (props) => <View >
<LinearGradient
style={{ height: '100%', width: '100%', position: 'absolute' }}
start={{ x: 0, y: 1 }} end={{ x: 1, y: 0 }} colors={['#1A9EAE', '#4EAE7C']}
/>
<Header {...props} style={{ backgroundColor: Colors.transparent }} />
</View>,
}
}
This works for me.
<Header
backgroundImage={require("../../assets/images/btn-header-background.png")}
centerComponent={{
text: i18n.t("stats.title"),
style: { fontFamily: "FunctionLH", fontSize: 30, color: "#fff" }
}}
containerStyle={{
backgroundColor: "transparent",
justifyContent: "space-around"
}}
statusBarProps={{ barStyle: "light-content" }}
/>
