Making an EditText field accept only letters and white spaces in Android

Question

I have an EditText field in my project which stands for the full name of the person.So I want only letters and spaces to be allowed in it.So I tried the following in the

Answer 1

For some reason the inclusion of "\n" can not occur at the end of the string, I searched the Google documentation, most found nothing. the only way to achieve spaces and line break is including in the middle of the string. See the example I used in one of my apps.

android:digits="aãâáàbcçdeéfghiíjklmnoõôóòpqrstuvwxyzAÃÂÁÀBCÇDEÉFGHIÍJKLMNOÕÔÓÒPQRSTUVWXYZ1234567890@-_'+=(){}[]*%$#!?,.;\n: /?\\"

Answer 2

Try this solution, it block entering number, special characters except space.

editText.setFilters(new InputFilter[] {
   new InputFilter() {
   @Override
   public CharSequence filter(CharSequence cs, int start,
       int end, Spanned spanned, int dStart, int dEnd) {

   return cs.toString().replaceAll("[^a-zA-Z ]*","");
    }
    }
});

Kotlin Version:

editText.filters = arrayOf(
            InputFilter { source, start, end, dest, dstart, dend ->
                return@InputFilter source.replace(Regex("[^a-zA-Z ]*"), "")
            }
        )

Answer 3

Add this line in your EditText tag.

android:digits="abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"

Your EditText tag should look like:

<EditText
        android:id="@+id/edt"
        android:digits="abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" />

it works perfectly and no validation condition required

update 1

regex src.toString().matches("[a-zA-Z ]+")

---

update 2

Fair enough if that's the case then simply add space in between.

android:digits="abcdefghijklmnopqrstuvwxyz ABCDEFGHIJKLMNOPQRSTUVWXYZ"

<EditText android:inputType="textPersonName" />
