I'm trying to align my component TextInput that uses a TextField from #ubaids/react-native-material-textfield and a Text but i couldn’t. The result i have is in the image below :
I added alignItems: 'center' in the container but i didn't work. My code is:
<View style={styles.container}>
<View style={styles.input}>
<TextInput
containerStyle={{ height: 20, marginVertical: 10 }}
label=""
value=""
keyboardType="phone-pad"
/>
</View>
<View style={styles.label}>
<Text style={[styles.text, { textTransform: 'uppercase' }]}>Text</Text>
</View>
</View>
container: {
flexDirection: 'row',
alignItems: 'center'
},
input: {
flex: 0.2
},
label: {
paddingTop: 20,
paddingHorizontal: 10
},
You should try and add justifyContent to your container‘s Styling:
container: {
flexDirection: 'row',
alignItems: 'center',
justifyContent: 'center'
}
And also, you don't need the view above the Text with the styles.label.
This way, both your TextInput and your Text components will be aligned on both axis
You have to set display css property to inline-block for both input and label style:
text: {
fontWeight: "bold",
fontSize: "1.5rem",
marginVertical: "1em",
},
container: {
flexDirection: "row",
alignItems: "center"
},
input: {
flex: 0.2,
display: 'inline-block'
},
label: {
// paddingTop: 20,
paddingHorizontal: 10,
display: 'inline-block'
}
As you can see I commented paddingTop: 20 in label (but if you need, you can add it again but you have to add it to input also).
Here a codesandbox.
Already answered but I'd like to add a bit more on the topic and different ways to do it depending on your use case.
You can add adjustsFontSizeToFit={true} (currently undocumented) to Text Component to auto adjust the size inside a parent node.
<Text adjustsFontSizeToFit={true} numberOfLines={1}>Hiiiz</Text>
You can also add the following in your Text Component:
<Text style={{textAlignVertical: "center",textAlign: "center",}}>Hiiiz</Text>

I'm new to react-native-material and I have the label text on top of the input text image when I use the :
<View style={styles.layout} >
<TextInput label="Email" variant="outlined" style={styles.textInput} />
<View/>
const styles = StyleSheet.create({
layout: {
flex: 1,
flexDirection: "column",
justifyContent: "center",
alignItems: "center",
width: "100%"
},
textInput:{
width: "80%",
marginVertical: 10
},
});
Thank you in advance for your help.
I expect the label to stay on top as long as the there's an input in the TextInput
I am trying to create a calculator, but I am facing a problem when the text gets long because it turns into an ellipsis, so I used ScrollView. It can be scrolled by increasing the value of numberOfLines, but when I tried scrolling up, it bounced back, and I would like it to stay where it is scrolled.
I set adjustsFontSizeToFit to true but it gets smaller too much which is not the one I want.
You can test it from here https://snack.expo.dev/_i4anOJ8v
Here is the screenshot: https://imgur.com/a/BAYyN5e
Any help is appreciated
<View style={styles.fieldContainer}>
<ScrollView contentContainerStyle={styles.field}>
<Text
// adjustsFontSizeToFit={true}
numberOfLines={500}
style={{
fontSize: textFontSize,
}}>
{text}
</Text>
</ScrollView>
</View>;
const styles = StyleSheet.create({
fieldContainer: {
flex: 1,
justifyContent: 'flex-end',
alignItems: 'flex-end',
},
field: {
marginTop: 'auto',
justifyContent: 'flex-end',
alignItems: 'flex-end',
flexDirection: 'column',
},
});
==> you need to change your style in scrollview.
field: {
justifyContent: 'flex-end',
alignItems: 'flex-end',
flexDirection: "column",
},
I'm trying to have my two buttons sit in a row, equally spaced, and I want them of equal height and width. But they look like this at the moment.
I'm very new to React Native so please go gently!
Here's my code for what's returned.
return (
<View style={styles.screen}>
<View style={styles.horseProfile}>
<HorseProfile />
</View>
<View style={styles.vitalSignsGrid}>
<LargeVitalSigns />
</View>
<View style={styles.buttonContainer}>
<TouchableOpacity onPress={this._alertHandler}>
<View style={styles.buttonStyling}>
<Text style={styles.buttonText}>ECG</Text>
</View>
</TouchableOpacity>
<TouchableOpacity onPress={this._alertHandler}>
<View style={styles.buttonStyling}>
<Text style={styles.buttonText}>Resp Pattern</Text>
</View>
</TouchableOpacity>
</View>
<View>{/* timer and stop button */}</View>
</View>
)
Here are my styles.
const styles = StyleSheet.create({
screen: {
flex: 1,
justifyContent: 'center',
alignItems: 'center'
},
horsePatientProfile: {
flex: 1
},
vitalSignsGrid: {
flex: 3,
backgroundColor: '#14172B'
},
buttonContainer: {
flexDirection: 'row',
justifyContent: 'space-around',
backgroundColor: 'green',
width: '100%',
flex: 4
},
buttonStyling: {
backgroundColor: '#2B4250',
borderRadius: 30,
alignItems: 'center',
justifyContent: 'space-around',
width: '50%',
height: '35%',
flexDirection: 'row',
},
buttonText: {
color: '#84C5C6',
fontWeight: 'bold'
}
})
Can anyone help please? Thank you.
the width of your buttons styles.buttonStyling is 50% which is 50% of the parent Component, the parent is the touchableOpacity, since it doesn't have a set width itself it will stretch with the content, in other words the 50% does not mean the same thing, you should give an exact (relative size, I like react-native-size-matter) to the touchable opacity and justifyContent as space between to space evenly
For height, width try using React Native Dimensions React Native Dimentions
Import it:
import {Dimensions} from "react-native";
var {height, width} = Dimensions.get('window');
Example using in style:
buttonStyling: {
backgroundColor: '#2B4250',
borderRadius: 30,
alignItems: 'center',
justifyContent: 'space-around',
width: width/2,
height: height / 3.5,
flexDirection: 'row',
},
or use Flexbox
I currently have a multiline textInput that automatically expands and a button below it. The problem is that the button's location seems to be fixed, it doesn't move down and textInput would just run over it.
Everything is wrapped in a KeyboardAvoidingView:
<KeyboardAvoidingView
style={styles.container}
behavior="padding">
<StatusBar barStyle="light-content"/>
<Text style={styles.title}>{this.state.form.prompt}</Text>
<View style={styles.simpleContainer}>
{this._renderForms()}
<View style={[styles.forwardButtonLocation, styles.indentLeft]}>
<ForwardButton
onButtonPress={this._submitInfo}
/>
</View>
</View>
<View style={{flex: 1, justifyContent: 'flex-end', alignItems: 'flex-end',}}>
<SkipButton
onButtonPress={this._nextState}
/>
</View>
</KeyboardAvoidingView>
this._renderForms() renders the corresponding form for each state, in this case, it renders:
<View style={styles.simpleContainer}>
<AutoExpandingTextInput
style={styles.textContentDark}
placeholder={this.state.form.userInput}
placeholderTextColor={DARK_THEME_CONTENT_COLOR_SECONDARY}
onChangeText={(userInputValue) =>
//TODO: Saving text to nested userInput is causing problem, temporarily save it to userInputValue
//this.setState({form: {...this.state.form, userInput: text}}
this.setState({userInputValue}
)}
/>
</View>
Here is my style sheet:
const styles = StyleSheet.create({
simpleContainer: {
flex:1,
justifyContent: 'center',
},
container: {
flex: 1,
justifyContent: 'space-between',
backgroundColor: THEME_COLOR,
},
title: {
flex: 1,
marginTop: '15%',
marginLeft: '3%',
fontWeight: 'bold',
fontSize: TITLE,
color: DARK_THEME_CONTENT_COLOR_PRIMARY,
},
textContentDimmed: {
fontSize: TITLE_SECONDARY,
color: DARK_THEME_CONTENT_COLOR_SECONDARY,
},
textContentWhite: {
fontSize: TITLE_SECONDARY,
color: DARK_THEME_CONTENT_COLOR_PRIMARY,
},
textContentDark: {
fontSize: TITLE_SECONDARY,
color: LIGHT_THEME_CONTENT_COLOR_SECONDARY,
},
indentLeft: {
marginLeft:'10%',
},
forwardButtonLocation: {
flex: 1,
justifyContent: 'flex-start',
},
whiteLine: {
width: '100%',
height: 1,
marginTop: 4,
marginHorizontal: '6%',
backgroundColor: DARK_THEME_CONTENT_COLOR_PRIMARY,
},
});
Is there any way to automatically relocate the button when the size of the textInput changes?
In react native I have:
<View style={styles.navBar}>
<Text>{'<'}</Text>
<Text style={styles.navBarTitle}>
Fitness & Nutrition Tracking
</Text>
<Image source={icon} style={styles.icon}/>
</View>
with these styles:
{
navBar: {
height: 60,
flexDirection: 'row',
justifyContent: 'space-between',
alignItems: 'center',
},
navBarTitle: {
textAlign: 'center',
},
icon: {
height: 60,
resizeMode: 'contain',
},
}
This is the effect I get:
This is the effect I want:
In the first example, the spacing between items is equal.
In the second example, each item is justified differently. The first item is left-justified. The second item is center-justified. The third, right-justified.
This question is similar, but it looks like react native does not support margin: 'auto'. Furthermore, the other answers only work if you only care about left and right justification, but no one really addresses center justification without auto margin.
I am trying to make a navigation bar in react native. The vanilla ios version looks like this:
(source: apple.com)
How do I do something similar? I'm mainly concerned with centering.
One way is to use nested View (flex containers) for 3 different regions and set flex:1 to left and right region
<View style={styles.navBar}>
<View style={styles.leftContainer}>
<Text style={[styles.text, {textAlign: 'left'}]}>
{'<'}
</Text>
</View>
<Text style={styles.text}>
Fitness & Nutrition Tracking
</Text>
<View style={styles.rightContainer}>
<View style={styles.rightIcon}/>
</View>
</View>
const styles = StyleSheet.create({
navBar: {
height: 60,
flexDirection: 'row',
justifyContent: 'space-between',
alignItems: 'center',
backgroundColor: 'blue',
},
leftContainer: {
flex: 1,
flexDirection: 'row',
justifyContent: 'flex-start',
backgroundColor: 'green'
},
rightContainer: {
flex: 1,
flexDirection: 'row',
justifyContent: 'flex-end',
alignItems: 'center',
backgroundColor: 'red',
},
rightIcon: {
height: 10,
width: 10,
resizeMode: 'contain',
backgroundColor: 'white',
}
});
You could also set marginLeft: 'auto' to the middle component. It should push it to the right. Also works for React Native

If you're using a NavigationBar from the Navigator module see my question: Changing the default style for a Navigator.NavigationBar (title)
use this
marginLeft: "auto",
marginRight: "auto"
