Android模仿软键盘实现软键盘的删除功能(逐个删除EditT

直接在删除的点击事件里加入以下代码即可:

int  keyCode = KeyEvent.KEYCODE_DEL;
KeyEvent keyEventDown = new KeyEvent(KeyEvent.ACTION_DOWN, keyCode);
KeyEvent keyEventUp = new KeyEvent(KeyEvent.ACTION_UP, keyCode);
editText.onKeyDown(keyCode, keyEventDown);
editText.onKeyUp(keyCode, keyEventUp);
