您好 我有一个EditText上,我想,让用户只输入非数字字符(比如AZ或az):有没有办法做到这一点?所有我所用的组合(文字,textPersonName的等等),让用户还可以选择号码。

Hello i have an EditText on which i would like to let user enter only non-numeric chars (say A-Z or a-z): is there a way to do it? All the combinations i used (text,textPersonName an so on) let the user select also numbers.

在此先感谢 ℃。

推荐答案

我认为你必须写自己的输入过滤器,并将其添加到组过滤器的的EditText。这样的事情可能工作:

I think you have to write your own InputFilter and add it to the set of filters for the EditText. Something like this might work:

InputFilter filter = new InputFilter() { 
    public CharSequence filter(CharSequence source, int start, int end, 
        Spanned dest, int dstart, int dend)
    {
        for (int i = start; i < end; i++) { 
            if (!Character.isLetter(source.charAt(i))) { 
                return ""; 
            }
        }
        return null; 
    } 
}; 
edit.setFilters(new InputFilter[]{filter});
