I'm on expo and going back and forth about this. I'm trying to clean the header part on top of my contents as well as the bottom part. When I ran the code without the navigation container, everything works fine as designed, but now I have to route new screens and bind to the buttons, I can't remove it. I tried everything from the main container stylesheet setting margin to 0 and padding to 0. I have and Globalstyle as well to shove all components to a clear clearn with proper margins.
If you take a look, there are dark bars on the top and the bottom part of the screen. I wanted to remove specifically that.
export default function App() {
const Stack = createStackNavigator();
return (
<NavigationContainer style={GlobalStyles.NotchAware}>
<Stack.Navigator initialRouteName="Home"
>
<Stack.Screen
name="Home"
component={Welcome}
options={{
headerShown:false,
}}
/>
</Stack.Navigator>
</NavigationContainer>
) ;
}
with this mere styling for the app.js
NotchAware: {
flex: 1,
paddingTop: Platform.OS === 'android' ? 25 : 0,
marginLeft: 5,
marginRight: 5,
marginBottom: 5,
},
These are some of the component code and styling.
export default function Welcome() {
const [active, setActive] = useState(0);
const nextAction = () => {
}
const skipAction = () => {
}
return (
<SafeAreaView style={styles.container}>
<StatusBar style="auto" />
<View style={styles.cardContainer}>
<WelcomeCard />
</View>
<View style={styles.cardTextContainer}>
<Text style={styles.cardText}>Let’s make learning more fun than ever.</Text>

);
}

Hi I'm building an app for IOS and Android with react Native, and I'm a newbie this is my first app, and I think I'm not too bad, but I have a UI that is only a supermarket list, but I have the head ready but I need place the below the image , I made a new View but it comes out in the middle of the screen. Can you explain to me why it is not shown where to go, thanks.
Can you explain to me why? Thanks I share codes
enter image description here
import { Button, Image, StyleSheet, Text, View } from 'react-native';
import { StatusBar } from 'expo-status-bar';
export default function App() {
return (
<View style={styles.container}expoex>
<View style={styles.header}>
<View style={styles.imageContainer}>
<Image style= {styles.logo} source={require('./assets/logo.png')} />
</View>
<View style={styles.menu}>
<Image source={require('./assets/menu3.png')} />
<Image source={require('./assets/menu2.png')} />
<Image source={require('./assets/menu5.png')} />
<Image source={require('./assets/menu1.png')} />
<Image source={require('./assets/menu4.png')} />
</View>
</View>
<View style={styles.textNomList}>
<Text style={styles.textNom}>Lista de Supermercado</Text>
</View>
<StatusBar style="auto" />
</View>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: '#6E04BF',
color: '#fff',
alignItems: 'center',
},
header: {
marginTop:62,
flex:1,
flexDirection:'row',
justifyContent:'center',
alignItems:'flex-start',
height: 145,
marginVertical: 10,
},
imageContainer: {
alignItems: 'center',
justifyContent: 'center',
marginLeft:5,
height: 145,
},
logo: {
width: 100,
height: 140,
},
menu: {
flex:1,
flexDirection:'row',
justifyContent:'space-between',
marginHorizontal: 20,
marginTop:15,
height:145,
},
textNomList: {
flex:1,
alignItems:'flex-start',
justifyContent:'flex-start',
},
textNom: {
color: '#fff',
fontSize: 16,
fontWeight: 'bold',
marginLeft: 20,
},
});
the result of this code is
enter image description here
I only can see some styling issues, check out below, edit it as required
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: '#6E04BF',
color: '#fff',
alignItems: 'center',
},
header: {
marginTop: 62,
// flex: 1,
flexDirection: 'row',
// justifyContent: 'center',
// alignItems: 'flex-start',
// height: 145,
// marginVertical: 10,
},
imageContainer: {
// alignItems: 'center',
// justifyContent: 'center',
marginLeft: 5,
height: 145,
},
logo: {
width: 100,
height: 140,
backgroundColor:'fff'
},
menu: {
// flex: 1,
flexDirection: 'row',
justifyContent: 'space-between',
marginHorizontal: 20,
marginTop: 15,
height: 145,
},
textNomList: {
flex: 1,
alignItems: 'flex-start',
justifyContent: 'flex-start',
},
textNom: {
color: '#fff',
fontSize: 16,
fontWeight: 'bold',
marginLeft: 20,
},
});
You should put your text in the same View that is wrapping your image and then style it appropriately.
<View style={styles.imageContainer}>
<Image style= {styles.logo} source={require('./assets/logo.png')} />
<Text style={styles.textNom}>Lista de Supermercado</Text>
</View>
I am not good at styling but it looks like your app should look decent with how the styles are at the current moment.
I´m trying without success to use the ScrollView component in React Native, below the code:
const width_proportion = '97%';
const height_proportion = '75%';
const styles = StyleSheet.create({
container: {
height: '100%'
},
image: {
flex: 1,
resizeMode: "cover",
justifyContent: "center"
},
text: {
color: "grey",
fontSize: 30,
fontWeight: "bold"
},
popup: {
color: '#CA0',
},
box: {
width: width_proportion,
height: height_proportion,
alignItems: 'center',
justifyContent: 'center',
backgroundColor: 'steelblue',
// position: "absolute",
marginTop: '5%',
marginBottom: '3%',
marginLeft: '2%'
},
bottomBox: {
width: '97%',
height: 125,
backgroundColor: 'steelblue',
marginLeft: '2%',
marginBottom: 10,
marginTop: 5,
padding: 5
}
});
const MyTheme = {
colors: {
...DefaultTheme.colors,
background: '#EFA',
primary: '#000',
text: '#000',
},
};
function HomeScreen({ navigation }) {
return (
<View style={styles.container}>
<View style={{ width: '100%', height: 50, backgroundColor: 'steelblue' }}>
<TouchableOpacity onPress={() => navigation.toggleDrawer()}>
<Image source={hamburgerMenu} style={{ height: 45, width: 45, alignItems: 'center' }}>
</Image>
</TouchableOpacity>
</View>
<ImageBackground source={imgBackground} style={styles.image}>
<View style={styles.box}>
</View>
<ScrollView horizontal={true} >
<View style={styles.bottomBox}>
</View>
<View style={styles.bottomBox}>
</View>
<View style={styles.bottomBox}>
</View>
</ScrollView>
</ImageBackground>
</View >
);
}
When I set the horizontal property to "true" from ScrollView, the component disappears. Only I set horizontal to "false" and the ScrollView workks fine in Vertical.
wrap your scrollview like this
<ScrollView horizontal={true}>
<View style={styles.bottomBox} />
<View style={styles.bottomBox} />
<View style={styles.bottomBox} />
</ScrollView>
bottomBox : {
width: 40,
height: 125,
backgroundColor: 'steelblue',
padding: 5,
marginRight: 10,
}
I'm building an app which uses the Map method to build several different components. I have a scrollview which contains the whole page. Currently, the scrollView won't expand to contain everything despite trying what is seemingly every bit of advice online.
I have tried having the scrollview be inside another view but that still doesn't work as well as a combination of different flex configurations. Does anyone know why this page in particular isn't working. I have compared it to other pages and there is seemingly no reason as to why the flex does not extend.
Thanks

EDIT: For anyone suffering from the same issue, REMOVE PERCENTAGES FROM HEIGHTS. This fixed this issue for me.
Maybe just use style instead of contentContainerStyle ? the doc says :
These styles will be applied to the scroll view content container which wraps all of the child views
So maybe here is your problem, you're not applying the flexGrow to the scrollView but to its wrapper
I can't get my app to fill the whole screen. Whatever i do, there is always a white bar on the bottom of the page. It's so strange because it works on some devices but not others. i'm going crazy over this!
Ive tried const { height, width } = Dimensions.get('window'); and setting the app height with that, and it actually worked once, but now i can't get it to work again. ive tried rewrapping everything in different ways, with different views and scrollviews.
ps.: i removed all functions and useless code so it's not too much code, but
here is my code

I think you're talking about the image background but not totally sure. I was able to get it to stretch to the full height by adding the following height declaration:
imagemBackground: {
flex: 1,
height: height,
},
link to example: https://snack.expo.io/r1Y-zpwMH
You are using flex:1 many times in style that is the problem.
please give flex:1 in container style and remove all flex:1 in other styles instead of flex:1 you can use width and height in percentage.
like style={{width:'100%',height:'40%'}}.
Thank you!
I am importing a custom component (RecipeCard) and it isn't appearing on the screen.
I'm fairly certain it is to do with the styling that I am currently using.
The fastimage component works exactly as the RN component does and can be seen here.
Any help is appreciated!

const styles = StyleSheet.create({
imageStyle: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
alignSelf: 'stretch',
backgroundColor: 'transparent',
},
titleContainer: {
position: 'absolute',
marginTop: 15,
zIndex: 2,
bottom: 13,
flex: 1,
width: '100%',
height: 70,
flexDirection: 'column',
alignItems: 'flex-start',
},
titleText: {

paddingLeft: 5,
paddingTop: 10
},
subtitleText: {
color: '#adadad',
fontWeight: '500',
paddingLeft: 5,
paddingTop: 5,
}
});
Try to add the resizeMode to the FastImage:
resizeMode={FastImage.resizeMode.contain}
It's also described in the docs of FastImage:
import FastImage from 'react-native-fast-image'
const YourImage = () =>
<FastImage
style={styles.image}
source={{
uri: 'https://unsplash.it/400/400?image=1',
headers:{ Authorization: 'someAuthToken' },
priority: FastImage.priority.normal,
}}
resizeMode={FastImage.resizeMode.contain}
/>
I tried the example you have given above, I was able to see the image with a little change in imageStyle, just added height and it was showing the images.
RecipeCard component
const RecipeCard = (props) => {
return (
<FastImage
style={styles.imageStyle}
source={{ uri: 'https://unsplash.it/400/400?image=1' }}
>
<View style={styles.titleContainer}>
<Text style={styles.titleText}>
{props.title}
</Text>
<Text style={styles.subtitleText}>
{props.subtitle}
</Text>
</View>
</FastImage>
);
}
In imageStyle I have added height
imageStyle: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
alignSelf: 'stretch',
backgroundColor: 'transparent',
height: 200
},
Hope this helps!
