重回关键的EditText活动 [英] Get back key event on EditText

问题描述

如何处理$ P $的pssing返回键，打字时的一个EditText的事件？当虚拟键盘显示并且用户presses背面，它就会被隐藏。我想处理此事件，但设置了OnKeyListener在EditText上没有帮助。

How can I handle the event of pressing back key while typing on an EditText? When the virtual keyboard is shown and the user presses back, it gets hidden. I want to handle this event, but setting an OnKeyListener in the EditText does not help.

推荐答案

感谢您里诺。它可能看起来工作，但我设法以不同方式解决这个问题。

Thank you Reno. It probably seems to work, but I managed to solve it differently.

我推翻的EditText的onKey $ P $宗座外方传教会（INT键code，KeyEvent的事件）。这种方法截获键presses的IME。 = D

I overrode EditText's onKeyPreIme(int keyCode, KeyEvent event). This method intercepts keypresses on the IME. =D

public boolean onKeyPreIme(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_BACK && 
        event.getAction() == KeyEvent.ACTION_UP) {
            // do your stuff
            return false;
    }
    return super.dispatchKeyEvent(event);
}
