一个简单的跨平台的按钮组件。可以进行一些简单的定制。

这个组件的样式是固定的。所以如果它的外观并不怎么搭配你的设计，那你需要使用TouchableOpacity或 是TouchableNativeFeedback组件来定制自己所需要的按钮，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"
/>;
