在React Native中创建具有透明背景的正方形progressBar

import React from 'react';
import { View, StyleSheet } from 'react-native';

const TransparentProgressBar = ({ progress }) => {
  return (
    <View style={styles.container}>
      <View style={[styles.progressBar, { width: `${progress}%` }]} />
    </View>
  );
};

const styles = StyleSheet.create({
  container: {
    width: '100%',
    height: 10,
    backgroundColor: 'rgba(0, 0, 0, 0.2)',
    borderRadius: 5,
    overflow: 'hidden',
  },
  progressBar: {
    height: '100%',
    backgroundColor: 'rgba(0, 0, 0, 0.5)',
  },
});

export default TransparentProgressBar;

import React from 'react';
import { View, StyleSheet } from 'react-native';
import TransparentProgressBar from './TransparentProgressBar';

const App = () => {
  const progress = 50; // 进度值，范围为0-100

  return (
    <View style={styles.container}>
      <TransparentProgressBar progress={progress} />
    </View>
  );
};

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
  },
});

export default App;
