问题描述
有没有一种方法，我可以指定一个输入掩码的EditText上控制Android的？
Is there a way I can specify an input mask to the EditText control in Android?
我希望能够指定类似### - ## - ####为一个社会安全号码。这将导致任何无效的输入被自动拒绝（例如，I型英文字母而不是数字组成）。
I want be able to specify something like ### - ## - #### for a Social Security Number. This will cause any invalid input to be rejected automatically (example, I type alphabetical characters instead of numeric digits).
我知道我可以添加一个OnKeyListener和手动检查的有效性。但是，这是单调乏味的，我将不得不处理各种边缘情况。
I realize that I can add an OnKeyListener and manually check for validity. But this is tedious and I will have to handle various edge cases.

推荐答案
尝试使用的<$c$c>InputFilter而不是 OnKeyListener 。这意味着你不必担心跟踪单个键presses，它也将处理之类的东西粘贴到这将是痛苦的处理与 OnKeyListener 字段。
Try using an InputFilter rather than an OnKeyListener. This means you don't have worry about tracking individual key presses and it will also handle things like pasting into a field which would be painful to handle with an OnKeyListener.

You could have a look at the source of the InputFilter implementations that come with Android to give you a starting point for writing your own.
