如何在React Native中围绕文本居中放置椭圆边框？

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

const OvalBorderText = ({ text }) => {
  return (
    <View style={styles.container}>
      <View style={styles.ovalBorder}>
        <Text style={styles.text}>{text}</Text>
      </View>
    </View>
  );
};

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
  },
  ovalBorder: {
    width: 200,
    height: 100,
    borderRadius: 50,
    borderWidth: 2,
    borderColor: 'black',
    justifyContent: 'center',
    alignItems: 'center',
  },
  text: {
    fontSize: 16,
    fontWeight: 'bold',
  },
});

const App = () => {
  return (
    <View style={styles.container}>
      <OvalBorderText text="Hello React Native" />
    </View>
  );
};
