You can use this method:

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

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

                    String input = s.toString();

                    if (!input.isEmpty()) {

                        input = input.replace(",", "");

                        DecimalFormat format = new DecimalFormat("#,###,###");
                        String newPrice = format.format(Double.parseDouble(input));


                        myEditText.removeTextChangedListener(this); //To Prevent from Infinite Loop

                        myEditText.setText(newPrice);
                        myEditText.setSelection(newPrice.length()); //Move Cursor to end of String

                        myEditText.addTextChangedListener(this);
                    }

                }

                @Override
                public void afterTextChanged(final Editable s) {
                }
            });

And to get original text use this:

String input = myEditText.getText().toString();
input = input.replace(",", "");
