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';

export default 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',
  },
});

// skip this line if using Create React Native App
AppRegistry.registerComponent('TextInANest', () => TextInANest);

Props

style

Type	Required
style	No

• View Style Props...

• textShadowOffset: object: {width: number,height: number}

• color: color

• fontSize: number

• fontStyle: enum('normal', 'italic')

• fontWeight: enum('normal', 'bold', '100', '200', '300', '400', '500', '600', '700', '800', '900')

  Specifies font weight. The values 'normal' and 'bold' are supported for most fonts. Not all fonts have a variant for each of the numeric values, in that case the closest one is chosen.

• lineHeight: number

• textAlign: enum('auto', 'left', 'right', 'center', 'justify')

  Specifies text alignment. The value 'justify' is only supported on iOS and fallbacks to left on Android.

• textDecorationLine: enum('none', 'underline', 'line-through', 'underline line-through')

• textShadowColor: color

• fontFamily: string

• textShadowRadius: number

• includeFontPadding: bool (Android)

  Set to false to remove extra font padding intended to make space for certain ascenders / descenders. With some fonts, this padding can make text look slightly misaligned when centered vertically. For best results also set textAlignVertical to center. Default is true.

• textAlignVertical: enum('auto', 'top', 'bottom', 'center') (Android)

• fontVariant: array of enum('small-caps', 'oldstyle-nums', 'lining-nums', 'tabular-nums', 'proportional-nums') (iOS)

• letterSpacing: number (iOS)

• textDecorationColor: color (iOS)

• textDecorationStyle: enum('solid', 'double', 'dotted', 'dashed') (iOS)

• writingDirection: enum('auto', 'ltr', 'rtl') (iOS)

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

When numberOfLines is set, this prop defines how text will be truncated. numberOfLines must be set in conjunction with this prop.

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.

clip is working only for iOS

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

---

numberOfLines

Used to truncate the text with an ellipsis after computing the text layout, including line wrapping, such that the total number of lines does not exceed this number.

This prop is commonly used with ellipsizeMode.

Type	Required
number	No

---

onLayout

Invoked on mount and layout changes with

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

Type	Required
function	No

---

onLongPress

This function is called on long press.

e.g., onLongPress={this.increaseSize}>

Type	Required
function	No

---

onPress

This function is called on press.

e.g., onPress={() => console.log('1st')}

Type	Required
function	No

---

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.
