react native：按下时更改组件道具

Question

我正在尝试更改被点击按钮的属性：如果点击超过 3 次，我想禁用它。

这是我的代码：

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

const App = () => {
  const [pressedCount, setPressedCount] = useState(0);

  return (
    <View style={{ flex: 1, justifyContent: 'center' }}>
      <Text style={{ margin: 16 }}>
        {pressedCount > 0
          ? `The button was pressed ${pressedCount} times!`
          : 'The button isn\'t pressed yet'
        }
      </Text>
      <Button
        title='Press me'
        onPress={() => if (pressedCount>=3){Button.setState.({disabled:true})} else{setPressedCount(pressedCount+1)}}
      />
    </View>
  );
};

export default App;

我试过 if (pressedCount>=3){Button.props.disabled=true} else{setPressedCount(pressedCount+1)}} 但还是一样。

关于如何正确执行此操作的任何建议？

Answer 1

<Button
  title="Press me"
  onPress={() => setPressedCount((prevState) => prevState + 1)}
  disabled={pressedCount > 3}
/>;
