Answer 1

Modify the onChanged of Textedit via code that works. And you don’t even need a mask for it. Follow an example:

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

            }

            private String current = "";
            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {
                if(!s.toString().equals(current)) {
                    Locale myLocale = new Locale("pt", "BR");
                    //Nesse bloco ele monta a maskara para money
                    txtUnitario.removeTextChangedListener(this);
                    String cleanString = s.toString().replaceAll("[R$,.]", "");
                    Decimal parsed = Double.parseDouble(cleanString);
                    String formatted = NumberFormat.getCurrencyInstance(myLocale).format((parsed / 100));
                    current = formatted;
                    txtUnitario.setText(formatted);
                    txtUnitario.setSelection(formatted.length());

                    //Nesse bloco ele faz a conta do total (Caso a qtde esteja preenchida)
                    String qtde = txtQtdeLitros.getText().toString();

                    txtUnitario.addTextChangedListener(this);
                }
            }
            @Override
            public void afterTextChanged(Editable s) {

            }
        });

This is just a basic way to make a monetary field, there are many other ways to do and in my opinion, this type of field does not need a mask because you just say that it is currency type and treat the data using Decimal ( Always avoid working with Double or Float values when monetary ).
Detail, Using this logic instead of a mask vc will also give a super cool effect to Edittext as it will fill in from the pennies.

You can use this lib: https://github.com/santalu/mask-edittext

Then just add edittext already with xml mask:

 <com.santalu.maskedittext.MaskEditText
android:id="@+id/et_phone_number"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="@string/hint_phone_number"
android:inputType="number"
app:mask="#,##"/>
