android 软体键盘 实现 -- 断点记录

实现功能 下面的拨号部分

 

 

实现原理:  

1.地下是一个Popupwindow(里面填充多个ImageView)

2. 每个ImageView点击的时候. 触发 onKeyDown和onKeyUp

int  keyCode =KeyEvent.KEYCODE_DEL;  //这里是退格键

KeyEvent keyEventDown = new KeyEvent(KeyEvent.ACTION_DOWN, keyCode);

 

KeyEvent keyEventUp = new KeyEvent(KeyEvent.ACTION_UP, keyCode);

editNumber.onKeyDown(keyCode, keyEventDown);  // editNumber 是ImageView

editNumber.onKeyUp(keyCode, keyEventUp);
