Text Only Input EditText android

问题

I want to restric user from entering any special character or number into edit text, but programmatically it should allow.

I know I can make inputType="text" but it deals only with the softkeyboard. I think it can be achived with TextWatcher, but I am not able to gel evrything. Can anyone help ?

回答1:

editTextView.setInputType(InputType.TYPE_TEXT_VARIATION_NORMAL);

There are many other types of inputs available for Password, Email address etc. Please see This API Link

Thanks :)

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 "";
            }
        } });
