How to achieve this layout using single EditText

You have to implement TextWacher and delete each at a time for this, Your EditText looks like this

<EditText
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/editText"
    android:singleLine="true"
    android:text="______"
    android:inputType = "textNoSuggestions"
    android:letterSpacing="0.4" -->Its the spacing of letter
    android:textSize="29sp" />

And here is the implementation

EditText editText;
String text;
boolean delete = false;

    text = editText.getText().toString();

    editText.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {

            text = editText.getText().toString();
            if (count > after)
                delete = true;

        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {

            StringBuilder sb = new StringBuilder(s.toString());
            int replacePosition = editText.getSelectionEnd();

            if (s.length() != 6) { //where 6 is the character underline per text
                if (!delete) {
                    if (replacePosition < s.length())
                        sb.deleteCharAt(replacePosition);
                } else {
                    sb.insert(replacePosition, '_');
                }

                if (replacePosition < s.length() || delete) {
                        editText.setText(sb.toString());
                        editText.setSelection(replacePosition);
                } else {
                        editText.setText(text);
                        editText.setSelection(replacePosition - 1);
                }
            }
        }
        delete = false;
    }
    @Override
    public void afterTextChanged(Editable s) {
    }
});
