推荐答案

您可以通过下面的过滤器输入文本，

You can filter input text by following ,

etTwamboxName.setFilters(new InputFilter[] { new InputFilter() {
            public CharSequence filter(CharSequence src, int start, int end,
                    Spanned dst, int dstart, int dend) {

                Log.e("", "===> " + src);
                if (src.equals("")) { // for backspace
                    return src;
                }

                if (src.toString().matches("[a-zA-Z ]+.")) {
                    return src;
                }

                return "";
            }
        } });
