当我使用的EditText我有虚拟键盘。

When I'm using "EditText" I have the virtual keyboard.

pressing第一次后退按钮隐藏键盘。其次preSS调用我的活动onBack pressed回调。 OK，但是...

Pressing first time "Back" button hides the keyboard. Second press invokes "onBackPressed" callback in my activity. OK, but...

我不知道如何挂钩的第一preSS。我需要尽快虚拟键盘驳回处理输入数据。

I have no idea how to hook the very first press. I need to process input data as soon as the virtual keyboard dismissed.

任何想法是值得欢迎的。

Any ideas are welcome.

感谢。

推荐答案

在使用此方法键盘消失，您可以覆盖：

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);
  }
