如何通过React Native中的函数响应来使用组件？

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

const MyComponent = () => {
  const [count, setCount] = useState(0);
  
  // 其他组件逻辑...
}

const MyComponent = () => {
  const [count, setCount] = useState(0);
  
  const incrementCount = () => {
    setCount(count + 1);
  }
  
  return (
    <View>
      <Text>Count: {count}</Text>
      <Button title="Increment" onPress={incrementCount} />
    </View>
  );
}

const App = () => {
  return (
    <View>
      <MyComponent />
    </View>
  );
}
