关键侦听器的抽象基类。 为输入和编辑文本提供了基础。 当键被按下时，子类应覆盖onKeyDown(View, Editable, int, KeyEvent)和onKeyUp(View, Editable, int, KeyEvent)以插入字符。

As for all implementations of KeyListener, this class is only concerned with hardware keyboards. Software input methods have no obligation to trigger the methods in this class.
