当我使用EditText"时,我有虚拟键盘.
When I'm using "EditText" I have the virtual keyboard.
第一次按下返回"按钮会隐藏键盘.第二次按下在我的活动中调用onBackPressed"回调.好的,但是...
Pressing first time "Back" button hides the keyboard. Second press invokes "onBackPressed" callback in my activity. OK, but...
我不知道如何钩住第一次按下.我需要在虚拟键盘关闭后立即处理输入数据.
I have no idea how to hook the very first press. I need to process input data as soon as the virtual keyboard dismissed.
欢迎提出任何想法.
谢谢.
你可以用这个方法覆盖键盘消失的时候:
You can override when the keyboard disappears using this method:
public boolean onKeyPreIme(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK &&
event.getAction() == KeyEvent.ACTION_UP) {
// Do your thing here
return false;
}
return super.dispatchKeyEvent(event);
}
取自我的另一个答案@:Android:当键盘消失时,EditText 上的错误弹出窗口不会向下移动
Taken from my other answer @ : Android: Error popup on EditText doesn't move down when keyboard goes away
