用于获取虚拟键盘按键的Android虚拟键盘KeyListener

Question

我希望在每次按键时我需要更改计数器类似于Tweeter Thing但问题是OnEditorActionListener仅在用户按Enter或Done键时调用更改，我可以为此找到解决方案

Answer 1

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

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 .
