Anyone tell me how I make my button to lowercase in react native because I already get the answer in stack overflow but there is using touch opacity and that is the different component of button so I want the answer for button component
When I will type anything in under title props example
title='Hello'

you can use TouchableOpacity for your button
like this:
<TouchableOpacity
onPress={() => onClick}
style={{}}>
<Text
style={{
fontSize: 20,
alignSelf: 'center',
}}>
Hello
</Text>
</TouchableOpacity>
Install react-native-paper and import Button from react-native-paper and make uppercase prop to false.
import { Button } from 'react-native-paper';
<Button
mode="contained"
uppercase={false}
onPress={() => console.log('Hello')}>
Hello
</Button>
From your question I just understood that you only need to convert the button text to lower case. For that just replace {title} with {title.toLowerCase()} and it will convert the titles text to lower case.
I want to change style in part of Text in React Native.
I tried this :
<Text style={styles.parent}>
Dernier message : <Text style={[styles.children, {
color: 'red',
paddingLeft: 10,
borderWidth: 5,
borderColor: 'black',
}]}>Coucou</Text>
</Text>
const styles = StyleSheet.create({
parent: {
backgroundColor: 'yellow',
},
children: {
backgroundColor: 'blue',
},
})
Parent background color is changed - good
Children color and background color is changed - good
Children padding left and border is not changed
Can you help me ? Thanks
The <Text> element is special as far as layout is concerned. From the docs: "everything inside is no longer using the flexbox layout but using text layout. This means that elements inside of a <Text> are no longer rectangles, but wrap when they see the end of the line."
To achieve what you seem to be looking for, it's probably advisable to use a wrapping<View> with two inner <Text>s.
PFB the expo snack link. Hope it helps

I using react-native 0.48.4 and using react-native-phone-input for phone number input. I found the module have using Modal. When Modal show, StatusBar are hidden, I tried to set StatusBar.setHidden(false); , StatusBar still hidden. How do make the StatusBar show when Modal called.
<Modal
animationType={'slide'}
transparent
visible={this.state.modalVisible}
onRequestClose={() => {console.log("Country picker has been closed.")}}
>
</Modal>
Personally i'm using the react-native modal repository provided by the react community for my modals implementation.
It handles a lot of default behaviour and provides a lot of feature, fully hackable.
When using this lib, to solve your problem, it would be a simple :
<Modal style={style.modal}>
<View style={{ flex: 1 }}>
<Text>Hello!</Text>
</View>
</Modal>
I personally apply this styling
modal: {
backgroundColor: 'white',
marginHorizontal: 0,
marginBottom: 0,
borderBottomLeftRadius: 0,
borderBottomRightRadius: 0,
borderTopLeftRadius: 10,
borderTopRightRadius: 10,
overflow: 'hidden',
}
To have something like:

Import_this
import {AppRegistry, Text, View, Button, StyleSheet} from 'react-native';
This my React Button code But style not working Hare ...
<Button
onPress={this.onPress.bind(this)}
title={"Go Back"}
style={{color: 'red', marginTop: 10, padding: 10}}
/>
Also I was try by this code
<Button
containerStyle={{padding:10, height:45, overflow:'hidden',
borderRadius:4, backgroundColor: 'white'}}
style={{fontSize: 20, color: 'green'}}
onPress={this.onPress.bind(this)} title={"Go Back"}
> Press me!
</Button>
Update Question:
Also I was try by This way..
<Button
onPress={this.onPress.bind(this)}
title={"Go Back"}
style={styles.buttonStyle}
>ku ka</Button>
Style
const styles = StyleSheet.create({
buttonStyle: {
color: 'red',
marginTop: 20,
padding: 20,
backgroundColor: 'green'
}
});
But No out put:
Screenshot of my phone:-
The React Native Button is very limited in what you can do, see; Button
It does not have a style prop, and you don't set text the "web-way" like <Button>txt</Button> but via the title property <Button title="txt" />
If you want to have more control over the appearance you should use one of the TouchableXXXX' components like TouchableOpacity
They are really easy to use :-)
I had an issue with margin and padding with a Button. I added Button inside a View component and apply your properties to the View.
<View style={{margin:10}}>
<Button
title="Decrypt Data"
color="orange"
accessibilityLabel="Tap to Decrypt Data"
onPress={() => {
Alert.alert('You tapped the Decrypt button!');
}}
/>
</View>
React Native buttons are very limited in the option they provide.You can use TouchableHighlight or TouchableOpacity by styling these element and wrapping your buttons with it like this
<TouchableHighlight
style ={{
height: 40,
width:160,
borderRadius:10,
backgroundColor : "yellow",
marginLeft :50,
marginRight:50,
marginTop :20
}}>
<Button onPress={this._onPressButton}
title="SAVE"
accessibilityLabel="Learn more about this button"
/>
</TouchableHighlight>
You can also use react library for customised button .One nice library is react-native-button (https://www.npmjs.com/package/react-native-button)
If you do not want to create your own button component, a quick and dirty solution is to wrap the button in a view, which allows you to at least apply layout styling.
For example this would create a row of buttons:
<View style={{flexDirection: 'row'}}>
<View style={{flex:1 , marginRight:10}} >
<Button title="Save" onPress={() => {}}></Button>
</View>
<View style={{flex:1}} >
<Button title="Cancel" onPress={() => {}}></Button>
</View>
</View>
Instead of using button . you can use Text in react native and then make in touchable
<TouchableOpacity onPress={this._onPressButton}>
<Text style = {'your custome style'}>
button name
</Text>
</TouchableOpacity >
Style in button will not work, You have to give style to the view.
<View style={styles.styleLoginBtn}>
<Button
color="orange" //button color
onPress={this.onPressButton}
title="Login"
/>
</View>
Give this style to view
const styles = StyleSheet.create({
styleLoginBtn: {
marginTop: 30,
marginLeft: 50,
marginRight: 50,
borderWidth: 2,
borderRadius: 20,
borderColor: "black", //button background/border color
overflow: "hidden",
marginBottom: 10,
},
});
Only learning myself, but wrapping in a View may allow you to add styles around the button.
const Stack = StackNavigator({
Home: {
screen: HomeView,
navigationOptions: {
title: 'Home View'
}
},
CoolView: {
screen: CoolView,
navigationOptions: ({navigation}) => ({
title: 'Cool View',
headerRight: (<View style={{marginRight: 16}}><Button
title="Cool"
onPress={() => alert('cool')}
/></View>
)
})
}
})
Try This one
<TouchableOpacity onPress={() => this._onPressAppoimentButton()} style={styles.Btn}>
<Button title="Order Online" style={styles.Btn} > </Button>
</TouchableOpacity>
You can use Pressable with Text instead of button.
import { StyleSheet, Text, View, Pressable } from 'react-native';
<Pressable style={styles.button} onPress = {() => console.log("button pressed")}>
<Text style={styles.text}>Press me</Text>
</Pressable>
Example Style:
const styles = StyleSheet.create({
button: {
alignItems: 'center',
justifyContent: 'center',
paddingVertical: 12,
paddingHorizontal: 32,
borderRadius: 4,
elevation: 3,
backgroundColor: 'red'
},
text: {
fontSize: 16,
lineHeight: 21,
fontWeight: 'bold',
letterSpacing: 0.25,
color: 'white',
},
});
We can use buttonStyle prop now.

React-native button is very limited, it won't allow styling. use react native elements button or create custom button
button styles does'nt work in react-native, to style your button in react-native easy way is to put it inside the View block like this:
<View
style={styles.buttonStyle}>
<Button
title={"Sign Up"}
color={"#F31801"}/>
</View>
style.buttonStyle be like this:
style.buttonStyle{
marginTop:30,
marginLeft:50,
marginRight:50,
borderWidth:2,
borderRadius:20,
borderColor:'#F31801',
overflow:"hidden",
marginBottom:10,
}
, it will make you able to use designs with buttons
As the answer by #plaul mentions TouchableOpacity, here is an example of how you can use that;
<TouchableOpacity
style={someStyles}
onPress={doSomething}
>
<Text>Press Here</Text>
</TouchableOpacity>
SUGGESTION:
I will recommend using react-native-paper components as they are modified and can be modified much more than react-native components.
To install;
npm install react-native-paper
Then you can simply import them and use.

Wrap the button component inside a view component and change the styles of the view component, it should work. Please refer to the snippet below
<View style={{width: 150, alignSelf: 'center'}}>
<Button onPress={demoFunction} title="clickMe!!" />
</View>
I know this is necro-posting, but I found a real easy way to just add the margin-top and margin-bottom to the button itself without having to build anything else.
When you create the styles, whether inline or by creating an object to pass, you can do this:
var buttonStyle = {
marginTop: "1px",
marginBottom: "1px"
}
It seems that adding the quotes around the value makes it work. I don't know if this is because it's a later version of React versus what was posted two years ago, but I know that it works now.
