    // 设置轨迹的颜色为不可更改
    const trackStyle = { backgroundColor: 'gray' };

    return (
      <Slider
        {...this.props}
        trackStyle={trackStyle}
      />
    );
  }
}

export default CustomSlider;

import React from 'react';
import { View } from 'react-native';
import CustomSlider from './CustomSlider';

class App extends React.Component {
  render() {
    return (
      <View>
        <CustomSlider
          minimumValue={0}
          maximumValue={100}
          value={50}
          // 其他属性
        />
      </View>
    );
  }
