如何从一个Android的EditText字段限制的特殊字符？

How to restrict special characters from an Android EditText field?

推荐答案

您是否尝试添加安卓位数=ABCDE ..... 0123456789属性？ 虽然安卓位数指定它是一个数字字段，它的工作对我来说，将其设置为接受信件，以及和特殊字符，以及（在SDK-测试7）。

Have you tried adding the android:digits="abcde.....0123456789" attribute? Although the android:digits specify that it is a numeric field, it does work for me to set it to accept letters as well, and special characters as well (tested on SDK-7).

如果这不工作，那么你就必须实施的KeyListener 请参见：http://developer.android.com/reference/android/widget/TextView.html#setKeyListener(android.text.method.KeyListener)

If this doesn't work then you'll have to implement KeyListener see: http://developer.android.com/reference/android/widget/TextView.html#setKeyListener(android.text.method.KeyListener)
