如何限制 Android EditText 字段中的特殊字符?
How to restrict special characters from an Android EditText field?
推荐答案
你试过添加 android:digits="abcde.....0123456789"
属性吗?虽然 android:digits
指定它是一个数字字段,但我可以将其设置为也接受字母和特殊字符(在 SDK-7 上测试).
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).
如果这不起作用,那么您将不得不实现 KeyListener
请参阅: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
