ToastAndroid

本模块将原生的 ToastAndroid 模块导出为一个 JS 模块，用于在 Android 设备上显示一个悬浮的提示信息。本模块包含一个show方法接受以下的参数：

• message 一个字符串，表示将要显示的文本内容。
• duration 提示信息持续显示的时间。可以是ToastAndroid.SHORT或者ToastAndroid.LONG。

还有一个名为showWithGravity的方法可以指定弹出的位置。可选项有：ToastAndroid.TOP, ToastAndroid.BOTTOM, ToastAndroid.CENTER.

The 'showWithGravityAndOffset(message, duration, gravity, xOffset, yOffset)' method adds the ability to specify an offset with in pixels.

Imperative hack

The ToastAndroid API is imperative, but there is a way to expose a declarative component from it as in this example:
