Andorid IME：Custom KeyBoard

在 Android 实现自定义键盘，以及输入法用到两个系统类。

Keyboard 和 KeyboardView

这两个系统类用于实现自定义的键盘。

根据官方文档，在 API 29 之后弃用。开发者可以重新实现，或者从 AOSP 中直接拷贝源码即可。

Keyboard

该类内部有个 Key，用于记录每个键的信息，code，height，width等。持有所有的 Key，并对外提供接口。

KeyboardView

负责绘制所有 Key，包括背景和动画。并监听 Touch 事件，根据 Touch 处的坐标，计算出点击的 Key，通过 OnKeyboardActilonListener 通知调用处，产生响应的结果。
