Question

在设备上运行时出现如下错误“按钮的 title 属性必须是字符串 - react native ”

import React, { Component } from 'react';
import {
AppRegistry,
StyleSheet,
Text,
Button,
View
} from 'react-native';

export default class sample extends Component {

render() {
return (
    <Button
      style={{fontSize: 20, color: 'green'}}
      styleDisabled={{color: 'red'}}
      onPress={() => this._handlePress()}>
      title="Press Me"
    </Button>
);
}


_handlePress() {
  console.log('Pressed!');
}
}

AppRegistry.registerComponent('sample', () => sample);

Answer 1

我认为您太早关闭了 Button 标签。

<Button
  style={{fontSize: 20, color: 'green'}}
  styleDisabled={{color: 'red'}}
  onPress={() => this._handlePress()}> // <-- closed tag here
  title="Press Me"
</Button>

只需关闭 title 属性后面的标签

<Button
  style={{fontSize: 20, color: 'green'}}
  styleDisabled={{color: 'red'}}
  onPress={() => this._handlePress()}
  title="Press Me"
>
  Press Me
</Button>
