In my application, I am using the below passwordTransformationClass for showing the password in asterisk format. The problem is, I want a space after each text in the edit text, i.e. a space after every asterisk. But the overridden methods don’t take space except a single asterisk character.

public class AsteriskPasswordTransformationMethod extends PasswordTransformationMethod {
    @Override
    public CharSequence getTransformation(CharSequence source, View view) {
        return new PasswordCharSequence(source);
    }

    private class PasswordCharSequence implements CharSequence {
        private CharSequence mSource;

        public PasswordCharSequence(CharSequence source) {
            mSource = source; // Store char sequence
        }

        public char charAt(int index)
        {

            return '*'; // This is the important part
        }

        public int length() {
            return mSource.length(); // Return default
        }

        public CharSequence subSequence(int start, int end) {
            return mSource.subSequence(start, end); // Return default
        }
    }
}

Input : <*****>

I hope this is your input in EditTextView and you want to transform the EditTextView text to something like

Output: <* * * * *>

then set some custom EditTextView fonts which have much spacing between characters...

Change font for EditText in Android?

and if you are going through Editext.addTextChangedListener, we can do it but we have to write down some expensive Logics into it to handle copy, paste, backspace and so many other cases .. :)

Try to change the code from

        public char charAt(int index)
        {
            return '*'; // This is the important part
        }

to 

        public string charAt(int index)
        {
            return "* "; // This is the important part
        }

  • @Tony- tried that. Its showing error there. It doesn't take more than 1 character. – Animesh Jena Jul 05 '16 at 07:52
  • @AnimeshJena have you tried to take the transformed text and modify it with spaces between asterisks? after you have transformed it to asterisks..then put a space between each asterisk – Antonios Tsimourtos Jul 05 '16 at 07:55
