我认为您太早关闭了 Button 标记。

 <Button
  style={{fontSize: 20, color: 'green'}}
  styleDisabled={{color: 'red'}}
  onPress={() => this._handlePress()}> // <-- closed tag here
  title="Press Me"
</Button>

只需在title属性后关闭标签

<Button
  style={{fontSize: 20, color: 'green'}}
  styleDisabled={{color: 'red'}}
  onPress={() => this._handlePress()}
  title="Press Me"
>
  Press Me
</Button>
