一个简单的跨平台的按钮组件。可以进行一些简单的定制。

如果这个组件外观并不怎么搭配你的设计，那你可以使用TouchableOpacity或是TouchableNativeFeedback组件来制作自己所需要的按钮，视频教程如何制作一个按钮讲述了完整的过程。或者你也可以在github.com网站上搜索'react native button'来看看社区其他人的作品。

用法示例：

<Button
  onPress={onPressLearnMore}
  title="Learn More"
  color="#841584"
  accessibilityLabel="Learn more about this purple button"
/>
