问题
There is a name EditText in my screen. I want to accept only alphabets means from a-z,A-Z
and should not accept numbers, special chars.
I'am using inputtype="textPersonName" for that but its notworking, it accepts means showing all numbers, chars etc..
For phone field inputtype="phone" is working it accepting means showing numbers in field` only.
Why like that?
回答1:
Your best bet is to use an InputFilter to restrict the characters that are permitted in your EditText control. You should be able to easily adapt the answer from How do I use InputFilter to limit characters in an EditText in Android? to do what you require.
回答2:
You will need to subclass EditText and detect key events. Reject any character other than a-zA-Z This is the only way to limit the acceptable characters.
A person's name could contain a number so textPersonName is working correctly.
回答3:
Try using TYPE_TEXT_VARIATION_PHONETIC
