I'm trying to create 3 TextInputs in one row, but when I write flexDirection: 'row' it doesn't work (I don't see any text inputs on device).
var SampleApp = React.createClass({
render: function() {
return (
<View style={styles.container}>
<View style={styles.textInputWrapper}>
<TextInput style={styles.textInput}
placeholder='Month'
placeholderTextColor="#d3d3d3"
/>
</View>
<View style={styles.textInputWrapper}>
<TextInput style={styles.textInput}
placeholder='Day'
placeholderTextColor="#d3d3d3"
/>
</View>
<View style={styles.textInputWrapper}>
<TextInput style={styles.textInput}
placeholder='Year'
placeholderTextColor="#d3d3d3"
/>
</View>
</View>
);
}
});
var styles = StyleSheet.create({
container: {
flex: 1,
flexDirection: 'row'
}
});
You need to add styles for each component. Hope that help.
var styles = StyleSheet.create({
container: {
flex: 1,
flexDirection: 'row'
},
textInputWrapper: {
flex:1,
height: 50,
borderColor:'red',
borderWidth: 2,
},
textInput:{
flex:1,
}
});

I am quite new to react native. I have created a FlatList for rendering this list of items, however, it is not scrolling. I've googled it for hours and tried nearly everything suggested in stack overflow threads - removed flex, added flex, wrapped it in a view, but nothing seems to work.
Here is my code (the issue is in the second FlatList) -
return(
<View style = {{ height: '100%' }}>
<View style = {{ width: '100%' }}>
<AppHeader />
</View>
<View style = {{ width: '100%'}}>
<View style = {{ width: '70%', alignSelf: 'center', flex: 1 }}>
<View>
<FlatList
data = {this.getTodayDay()}
renderItem = {this.renderItemDays}
keyExtractor = {this.keyExtractor}
/>
</View>
<FlatList
data = {this.getVisibleHours()}
renderItem = {this.renderItem}
keyExtractor = {this.keyExtractor}
scrollEnabled = {true}
/>
</View>
</View>
</View>
this.renderItem -
renderItem = () => {
// irrelevant code
if( isClass === true ){
return(
<ListItem bottomDivider = {true} style = {styles.renderItemActiveClass}>
<ListItem.Content>
<TouchableOpacity
onPress = {()=>{
this.props.navigation.navigate('ClassDetailsScreen', { "data": classData })
}}>
<ListItem.Title>{ definiteClassTime }</ListItem.Title>
<ListItem.Subtitle>{ classData.class_name }</ListItem.Subtitle>
</TouchableOpacity>
</ListItem.Content>
</ListItem>
)
}
else{
return(
<ListItem bottomDivider = {true} style = {styles.renderItemClass}
containerStyle = {styles.renderItemContent}>
<ListItem.Content>
<ListItem.Title>{item}:00</ListItem.Title>
<ListItem.Subtitle>No Class</ListItem.Subtitle>
</ListItem.Content>
</ListItem>
)
}
}
the StyleSheet -
renderItemClass: {
borderColor: 'purple',
borderWidth: 2
},
renderItemActiveClass: {
borderColor: 'green',
borderWidth: 2
},
renderItemContent: {
},
Could somebody please tell me what I'm doing wrong?
Add a height to both the flatlist. And also wrap your second flatlist within a seperate view. Here is an example:
return (
<View style={{ height: "100%" }}>
<View style={{ width: "100%" }}>
<AppHeader />
</View>
<View style={{ width: "100%" }}>
<View style={{ width: "70%", alignSelf: "center", flex: 1 }}>
<View style={{ height: 60, alignSelf: "center" }}>
<FlatList
data={this.getTodayDay()}
renderItem={this.renderItemDays}
keyExtractor={this.keyExtractor}
/>
</View>
<View style={{ height: 60, alignSelf: "center" }}>
<FlatList
data={this.getVisibleHours()}
renderItem={this.renderItem}
keyExtractor={this.keyExtractor}
scrollEnabled={true}
/>
</View>
</View>
</View>
</View>
);
I am new to react native.
I created some custom components in project. And I pass some style to them via the props but my passing styles are not attached to that components. At the first it was working correctly but suddenly I don't know what happened that my passing styles are not working.
Here is my code:
This the page where I used my custom component and passed style to that.
function StartGameScreen(props) {
const [confirmed, setConfirmed] = useState(false);
const [selectedNumber, setSelectedNumber] = useState();
const numInputHandler = (inputText) => {
setEneteredValue(inputText.replace(/[^0-9]/g, ""));
};
const confirmInput = () => {
const chosenNumber = parseInt(enteredValue);
if (isNaN(chosenNumber) || chosenNumber <= 0 || chosenNumber > 99) {
Alert.alert(
"Invalid number!",
"Number has to be a number between 0 and 99.",
[{ text: "Okay", style: "destructive", onPress: resetInput }]
);
return;
}
setConfirmed(true);
setSelectedNumber(chosenNumber);
setEneteredValue("");
Keyboard.dismiss();
};
let confirmedOutput;
if (confirmed) {
confirmedOutput = (
<Card style={styles.summeryContainer}>
<Text>You selected</Text>
<NumberContainer>{selectedNumber}</NumberContainer>
<Button
title="START GAME"
onPress={() => {
console.log("hello" + selectedNumber);
props.onStartGame(selectedNumber);
}}
/>
</Card>
);
}
return (
<TouchableWithoutFeedback
onPress={() => {
Keyboard.dismiss();
}}
>
<View style={styles.container}>
<Text style={styles.title}>Start A New Game!</Text>
*This is where I used my custom component (<Card>).*
<Card style={styles.inputContainer}>
<Text>select a number</Text>
<Input
style={styles.input}
blurOnSubmit
autoCapatilize="none"
autoCorrect={false}
keyboardType="number-pad"
maxLength={2}
onChangeText={numInputHandler}
value={enteredValue}
/>
<View style={styles.buttonCon}>
<View style={styles.button}>
<Button
title="Reset"
color={Colors.accent}
onPress={resetInput}
/>
</View>
<View style={styles.button}>
<Button
title="Confirm"
color={Colors.primary}
onPress={confirmInput}
/>
</View>
</View>
</Card>
{confirmedOutput}
</View>
</TouchableWithoutFeedback>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
padding: 10,
alignItems: "center",
},
inputContainer: {
width: 300,
maxWidth: "80%",
alignItems: "center",
},
input: {
textAlign: "center",
width: 50,
},
});
export default StartGameScreen;
And this is my Card custom component:
function Card(props) {
return (
<View style={{ ...styles.container, ...props.style }}>
{props.children}
</View>
);
}
const styles = StyleSheet.create({
container: {
shadowColor: "black",
shadowOffset: { width: 0, height: 2 },
shadowOpacity: 0.26,
shadowRadius: 6,
elevation: 12,
backgroundColor: "white",
padding: 20,
borderRadius: 10,
},
});
export default Card;
Change Your Card component like below then it will work
function Card(props) {
return (
<View style={[styles.container,props.style]}>
{props.children}
</View>
);
}
In my containerTop, I am rendering a list inside TripOptionsSelectorthat hides towards the end.
I have tried adding marginBottom/paddingBottom to containerOptionsSelectorbut it makes no difference. I don't want to add a height to my because it can vary according to different phones.
How else can I simply extend the View such that the text doesn't hide?
export const MapScreen: React.FunctionComponent = () => {
return (
<SafeAreaView style={styles.safeAreaViewContainer}>
<View style={styles.container}>
<View style={styles.containerTop}>
<BackArrow />
<JourneyLocationsTextContainer />
<View style={styles.containerOptionsSelector}>
<TripOptionsSelector />
</View>
</View>
<View style={styles.containerMap}>
<MapContainer />
<ButtonsContainer />
</View>
</View>
</SafeAreaView>
);
};
const styles = StyleSheet.create({
safeAreaViewContainer: { flex: 1 },
container: { flex: 1, backgroundColor: 'white'},
containerTop: { flex: 1, backgroundColor: '#323443' },
containerOptionsSelector: {
marginTop: moderateScale(15),
marginLeft: moderateScale(20),
},
containerMap: {
flex: 2
},
});
export const TripOptionsSelector: React.FunctionComponent = () => {
return (
<View style={styles.offerContainer}>
<Text style={styles.offerText}>Jetzt</Text>
<Text style={styles.offerText}>1 Person</Text>
<Text style={styles.offerText} >Filter</Text>
</View>
);
};
const styles = StyleSheet.create({
offerContainer: {
flexDirection: 'row',
},
You just remove flex from styles.containerTop - so it's sized based purely on its content.
I am a newbie to react native, I want to make this layout possible I have following code but it puts the logo inside grid
What I am looking for is this
import React, { Component } from 'react';
import GridView from 'react-native-super-grid';
export default class ProfileScreen extends Component {
static navigationOptions = {
title: 'Details',
};
render() {
const { navigate } = this.props.navigation;
const items = [
{ name: require('./images/shopping-cart.png'),code: '#2ecc71' }, { name: require('./images/home.png'), code: '#2ecc71' },
{ name: require('./images/money-bag.png'), code: '#2ecc71' }, { name: require('./images/alert.png'), code: '#2ecc71' }
];
return (
<ImageBackground
source={require('./images/marble.jpg')}
style={styles.backgroundImage}>
<View style={styles.mainLayout}>
<Image resizeMode={'cover'} style = {styles.logoFit} source={require('./images/Logo1.png')}/>
<GridView
itemDimension={130}
items={items}
style={styles.gridView}
renderItem={item => (
<View style={styles.itemContainer}>
<View style={styles.CircleShapeView}>
<Image style={styles.iconItem} source={item.name}/>
</View>
</View>
)}
/>
</View>
</ImageBackground>
);
}
}
const dimensions = Dimensions.get('window');
const imageHeight = Math.round(dimensions.width * 9 / 16);
const imageWidth = dimensions.width;
const styles = StyleSheet.create({
backgroundImage: {
flex: 1,
resizeMode: 'cover', // or 'stretch'
},
CircleShapeView: {
width: 100,
height: 100,
borderRadius: 100,
backgroundColor: '#00BCD4',
justifyContent: 'center',
alignItems: 'center'
},
gridView: {
paddingTop: 50,
flex: 1,
},
itemContainer: {
justifyContent: 'center',
alignItems:'center',
height:130
},
iconItem: {
alignItems:'center',
justifyContent: 'center'
},
logoFit: {
width: imageHeight,
height: imageWidth
},
mainLayout: {
flex: 1,
flexDirection: 'column',
justifyContent: 'space-between'
}
});
Get rid of that grid component. You don't need it for such a simple thing. It's complicating things, and as it's not a regular/common component we don't know how it's affecting things.
This looks quite simple:
<View>
<View style={{}}>
<Image />
</View>
<View style={{flexDirection:'row'}}>
<View>
<Text>row 1, col 1</Text>
</View>
<View>
<Text>row 1, col2Text>
</View>
</View>
<View style={{flexDirection:'row'}}>
<View>
<Text>row 2, col 1</Text>
</View>
<View>
<Text>row 2, col2Text>
</View>
</View>
<View style={{}}>
<Button title="Login" />
</View>
</View>

Inside navigationOptions You should remove the title property and define a header property and put your Image there. Like this
static navigationOptions = {
header:(<Image resizeMode={'cover'} style = {styles.logoFit} source={require('./images/Logo1.png')}/>)
};
Or... YOu can just make the header null as
static navigationOptions = {
header:null
};
and your current code would work as you want it to be.
I have a view having text inside it. The component looks like this:
MyComponent = () => {
return (
<View style={styles.viewStyle}>
<Text style={styles.textStyle}>My Text</Text>
</View>
);
}
const styles = {
viewStyle: {
backgroundColor: '#006699',
height: 40,
justifyContent: 'center',
alignItems: 'center',
},
textStyle: {
color: '#000000',
fontSize: 16,
}
}
When this component gets used, I want my View to have a custom width such that it just wraps my text. Here's the visual clue:
It's about the original design of Layout with Flexbox.
You can make it work by either add flexDirection: 'row' to it's parent view (so it will stretch automatically related to <Text /> width),
<View style={{flex: 1, flexDirection: 'row'}}>
<View style={styles.viewStyle}>
<Text style={styles.textStyle}>My Text</Text>
</View>
</View>
or give width to it directly.
<View style=[{styles.viewStyle}, {width: 50}]>
<Text style={styles.textStyle}>My Text</Text>
</View>
