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);

Reference

Props

pressRetentionOffset

When the scroll view is disabled, this defines how far your touch may move off of the button, before deactivating the button. Once deactivated, try moving it back and you'll see that the button is once again reactivated! Move it back and forth several times while the scroll view is disabled. Ensure you pass in a constant to reduce memory allocations.

Type	Required
object: {top: number, left: number, bottom: number, right: number}	No

---

accessible

When set to true, indicates that the view is an accessibility element. The default value for a Text element is true.

See the Accessibility guide for more information.

Type	Required
bool	No

ellipsizeMode

This can be one of the following values:

• head - The line is displayed so that the end fits in the container and the missing text at the beginning of the line is indicated by an ellipsis glyph. e.g., "...wxyz"
• middle - The line is displayed so that the beginning and end fit in the container and the missing text in the middle is indicated by an ellipsis glyph. "ab...yz"
• tail - The line is displayed so that the beginning fits in the container and the missing text at the end of the line is indicated by an ellipsis glyph. e.g., "abcd..."
• clip - Lines are not drawn past the edge of the text container.

The default is tail.

numberOfLines must be set in conjunction with this prop.

clip is working only for iOS

Type	Required
enum('head', 'middle', 'tail', 'clip')	No

{nativeEvent: {layout: {x, y, width, height}}}
