Text
A React component for displaying text.
Text
supports nesting, styling, and touch handling.
In the following example, the nested title and body text will inherit the fontFamily
from styles.baseText
, but the title provides its own additional styles. The title and body will stack on top of each other on account of the literal newlines:
import React, { Component } from 'react';
import { AppRegistry, Text, StyleSheet } from 'react-native';
class TextInANest extends Component {
constructor(props) {
super(props);
this.state = {
titleText: "Bird's Nest",
bodyText: 'This is not really a bird nest.'
};
}
render() {
return (
<Text style={styles.baseText}>
<Text style={styles.titleText} onPress={this.onPressTitle}>
{this.state.titleText}{'\n'}{'\n'}
</Text>
<Text numberOfLines={5}>
{this.state.bodyText}
</Text>
</Text>
);
}
}
const styles = StyleSheet.create({
baseText: {
fontFamily: 'Cochin',
},
titleText: {
fontSize: 20,
fontWeight: 'bold',
},
});
// App registration and rendering
AppRegistry.registerComponent('TextInANest', () => TextInANest);
