推荐答案

您可以使用的 OnKeyListener 如果你真的想赶上按键。

You could use an OnKeyListener if you do really want to catch keystrokes.

但是，如果你真正感兴趣的是什么，知道什么时候在的EditText 查看文本已经改变，你可能会发现更容易使用的 TextWatcher 。你会把你的code哪些更新根据的EditText 在<一个范围内的东西href="http://developer.android.com/reference/android/text/TextWatcher.html#afterTextChanged%28android.text.Editable%29"相对=nofollow> afterTextChanged（）方法。

However, if what you're really interested in is knowing when the text in an EditText View has changed you might find it easier to use a TextWatcher. You would put your code which updates something based on the context of the EditText in the afterTextChanged() method.
