Android Edit text Masking

Question

I want to add masking .. like 00000-0000000-0

etusercnic.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) {
            try {
                String str = s.toString();
                if (s.length() == 5 || s.length() == 13) {
                    str += "-";
                    etusercnic.setText(str);
                    etusercnic.setSelection(str.length());
                }
            } catch (Exception ignored) {
            }
        }

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

It works perfectly,when first time i entered the value, but when i remove any digit it placed - sign. so what can i do..

I'm sure you're masking it for CNIC :D

Anyways here is my version of masking, it works perfectly:

        etusercnic.setRawInputType(InputType.TYPE_CLASS_NUMBER); 
        etusercnic.addTextChangedListener(new TextWatcher() {
        int len = 0;
        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            // TODO Auto-generated method stub
            String val = etusercnic.getText().toString();
            if((val.length()==5 && len <val.length()) || (val.length()==13 && len<val.length())){
                etusercnic.append("-");
            }


        }

        @Override
        public void beforeTextChanged(CharSequence s, int start, int count,
                int after) {
            String str = etusercnic.getText().toString();
            len = str.length();

        }

        @Override
        public void afterTextChanged(Editable s) {
            // TODO Auto-generated method stub

        }
    });

The xml of your Edittext should be something similar to this:

 <EditText
    android:id="@+id/nic_field"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:hint="@string/signup_cnic_hint"
    android:singleLine="true"
    android:inputType="date"
    android:maxLength="15"
    android:textColor="#000000"
    android:textColorHint="#808080"
    android:textSize="15sp" 
     />
