React Native Animation does not scale. Animation is bigger. My code:
import { DangerZone } from 'expo';
const { Lottie } = DangerZone;
Styles:
animationContainer: {
backgroundColor: '#fff',
alignItems: 'center',
justifyContent: 'center',z
},
View:
<Lottie
ref={(animation) => {
this.animation = animation;
}}
resizeMode="contain"
loop={Boolean(true)}
style={{
width: 300,
height: 30,
backgroundColor: '#ccc',
}}
source={this.state.animation}
/>

I don`t know why this does not work. Please help me

I need to make the list of items touchable in a flatlist, but have no idea how to make the individual components touchable so i can access the id of that flatlist item. I need to handle the onPress so I can use react navigation 5 to send the users to a different screen.
I'm using an array of data to create a card like component that renders in the flatlist.
how do I make the individual list items touchable?
here's what I'm working with:
import * as React from "react";
import { View, StyleSheet, FlatList, SafeAreaView } from "react-native";
import BigButton from "../components/BigButton.js";
import HomeScreenImage from "../components/HomeScreenImage.js";
import HomeCard from "../components/Card";
const homeOptions = [
{
name: "Beast shedule",
body: "Create and manage your workout shedule",
image: require("../assets/images/DoubleBis.jpg"),
id: "1",
},
{
name: "Pre-Made Workouts",
body: "Use one of our pre-made workouts",
image: require("../assets/images/ChickA.jpg"),
id: "2",
},
{
name: "Statistics",
body: "Analyse your personal statistics",
image: require("../assets/images/WorkoutInProgress.jpg"),
id: "3",
},
{
name: "History",
body: "Keep track of your workout history",
image: require("../assets/images/ChickH.jpg"),
id: "4",
},
];
const HomeScreen = (props) => {
return (
<View style={Styles.containerTop}>
<View>
<HomeScreenImage style={Styles.top} />
<View style={Styles.top}>
<BigButton title="Train & Track" />
</View>
</View>
<SafeAreaView style={Styles.flatListContainer}>
<FlatList
data={homeOptions}
renderItem={({ item }) => {
return <HomeCard info={item} />;
}}
keyExtractor={(homeOption) => homeOption.id}
showsVerticalScrollIndicator={false}
/>
</SafeAreaView>
</View>
);
};
const Styles = StyleSheet.create({
containerTop: {
flex: 1,
backgroundColor: "#3E3636",
},
top: {
flex: 1,
height: "1%",
alignItems: "center",
justifyContent: "center",
},
flatListContainer: {
flex: 1,
},
});
export default HomeScreen;
import React from "react";
import { View, Text, StyleSheet, Dimensions, Image } from "react-native";
const HomeCard = (props) => {
return (
<View style={Styles.container}>
<View style={Styles.cardContainer}>
<Image style={Styles.imageStyle} source={props.info.image} />
<View style={Styles.infoStyle}>
<Text style={Styles.titleStyle}>{props.info.name}</Text>
<Text style={Styles.bodyTextStyle}>{props.info.body}</Text>
</View>
</View>
</View>
);
};
const deviceWidth = Math.round(Dimensions.get("window").width);
const offset = 25;
const radius = 20;
const Styles = StyleSheet.create({
container: {
width: deviceWidth - 20,
marginTop: 20,
},
cardContainer: {
margin: 10,
width: deviceWidth - offset,
backgroundColor: "#000",
height: 200,
borderRadius: radius,
shadowColor: "#000",
shadowOffset: {
width: 5,
height: 5,
},
shadowOpacity: 0.75,
shadowRadius: 5,
elevation: 3,
},
imageStyle: {
height: 130,
width: deviceWidth - 25,
borderTopLeftRadius: radius,
borderTopRightRadius: radius,
opacity: 0.95,
},
titleStyle: {
color: "#F5EDED",
textAlign: "center",
fontSize: 20,
fontWeight: "800",
},
bodyTextStyle: {
fontWeight: "200",
color: "#F5EDED",
textAlign: "center",
},
infoStyle: {
marginHorizontal: 10,
marginVertical: 1,
},
});
export default HomeCard;
You can wrap your card with some touchable component, like TouchableOpacity for example, with naviagtion.navigate('routeName', {params}) function on onPress prop.
const HomeCard = (props) => {
return (
<TouchableOpacity onPress={() => navigation.navigate('ReceiverRoute', {image: props.info image, name: props.info.name })}> ///etc any parameters you want
<View style={Styles.container}>
<View style={Styles.cardContainer}>
<Image style={Styles.imageStyle} source={props.info.image} />
<View style={Styles.infoStyle}>
<Text style={Styles.titleStyle}>{props.info.name}</Text>
<Text style={Styles.bodyTextStyle}>{props.info.body}</Text>
</View>
</View>
</View>
</TouchableOpacity>
);
};
and then you navigate to a component that can receive some params.
For a cleaner example you can look into docs. The main idea is just wrapping your card into some touchable with onpress navigation. For the navigation prop, you can either pass it to your card from parent component, or use useNavigation hook
I'm trying to fit my background image to cover the whole app but its not, even though i've tested most of similar threads here so any help is appreciated.
I've made some changes to the original source and added an arrow towards the left edge of the image that i was hoping to have at the edge when i open up the EXPO app on my phone, but i only see a few pixels of the arrow at the left edge.
**app.js**
function HomeScreen() {
return (
<ImageBackground source={require('./assets/bgImage.jpg')} style={styles.bgImage}>
<View>
<Text>Home Screen</Text>
</View>
</ImageBackground>
);
}
bgImage: {
flex: 1,
width: null,
height: null,
resizeMode: 'cover',
justifyContent: 'center',
alignItems: "center"
}
try this :-
import React from 'react';
import { ImageBackground, View, Text } from 'react-native';
const HomeScreen = () => {
return (
<ImageBackground source={require('../assets/apple.jpg')}
style={{
position: "absolute",
top: 0,
left: 0,
bottom: 0,
right: 0,
flex: 1,
alignItems: "center"
}}>
<View style={{
width: '90%',
height: 200,
backgroundColor: "red",
justifyContent: "center",
alignItems: "center",
}}>
<Text>Home Screen</Text>
</View>
</ImageBackground>
);
}
export default HomeScreen;
It is working fine.
I tried to run my code on various screen sized emulators and the layout of my design varies from device to device. I need help to make the layout more responsive and fixed on different sized screens such as tablets, 3"mobile and 6"mobile.
-----------or connect with us on----------- I want to style this line in better way and that remains the same look on every device
I tried using the dimensions of the screen by defining the width and height using variables, and by describing the values in percentages, but nothing worked.
import React, { Component } from 'react';
import { View,TouchableOpacity, Text, StyleSheet, Image, Dimensions } from 'react-native';

I want the layout to remain the same. Both the logo and buttons remain at the same position on every device display.
And I want a better dynamic solution for separator I have used in code
--------------or connect with us on-----------
I got a workaround solution for this problem. I am assigning values using the height and width of the screen to the styling.
import { StyleSheet, Dimensions } from 'react-native';
const { width: WIDTH, height: HEIGHT } = Dimensions.get('window');
SomeText: {
fontSize: HEIGHT / 38,
marginTop: WIDTH / 20,
}
I have created a react native project using react navigation.I have put a picture as a ImageBackground in root component.In android it works fine but in iOS it shows the root component background image but with transparent stack navigators.
<SafeAreaView style={{ flex: 1 }}>
<ImageBackground
source={Assets.bgImage}
style={{
width: '100%',
height: '100%'
}}
>
<Wrapper>{children}</Wrapper>
</ImageBackground>
</SafeAreaView>
{
initialRouteName: 'SignIn',
mode: 'card',
headerMode: 'none',
transparentCard: true,
transitionConfig: () => ({
containerStyle: {
backgroundColor: 'transparent'
}
}),
/* The header config from HomeScreen is now here */
defaultNavigationOptions: {
headerStyle: {
backgroundColor: 'transparent'
},
headerTintColor: '#fff',
headerTitleStyle: {
fontWeight: 'bold',
fontSize: 15
}
}
}
anyone has idea about this issue?
For some reason when I put Text inside Image it stops wrapping. I've tried flexWrap: 'wrap' but it doesn't help.
Here is how it looks like
If I put the Text outside of Image than it works OK.
Here is the code:
class wraptest extends Component {
render() {
return (
<View style={styles.container}>
<Image
source={require('./image.jpg')}
style={styles.image}>
<View style={styles.textContainer}>
<Text style={styles.text}>Text goes here.</Text>
</View>
</Image>
</View>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
},
image: {
flex: 1,
resizeMode: 'cover',
justifyContent: 'center',
},
textContainer: {
backgroundColor: 'transparent',
alignItems: 'center',
},
text: {
fontSize: 40,
fontWeight: 'bold'
}
});
I've also pushed full project here https://github.com/OleksandrBezhan/react-native-text-wrap-test
The reason the text wraps when it is outside of the image is because it is a direct child of the "container" style which defines the flex box. Try putting flex: 1 on either the textContainer or text styles.
