    public NumberTextWatcherForThousand(EditText editText) {
        this.editText = editText;


    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {

    }

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

    }

    @Override
    public void afterTextChanged(Editable s) {
        try
        {
            editText.removeTextChangedListener(this);
            String value = editText.getText().toString();


            if (value != null && !value.equals(""))
            {

                if(value.startsWith(".")){
                    editText.setText("0.");
                }
                if(value.startsWith("0") && !value.startsWith("0.")){
                    editText.setText("");

                }


                String str = editText.getText().toString().replaceAll(",", "");
                if (!value.equals(""))
                editText.setText(getDecimalFormattedString(str));
                editText.setSelection(editText.getText().toString().length());
            }
            editText.addTextChangedListener(this);
            return;
        }
        catch (Exception ex)
        {
            ex.printStackTrace();
            editText.addTextChangedListener(this);
        }

    }

    public static String getDecimalFormattedString(String value)
    {
        StringTokenizer lst = new StringTokenizer(value, ".");
        String str1 = value;
        String str2 = "";
        if (lst.countTokens() > 1)
        {
            str1 = lst.nextToken();
            str2 = lst.nextToken();
        }
        String str3 = "";
        int i = 0;
        int j = -1 + str1.length();
        if (str1.charAt( -1 + str1.length()) == '.')
        {
            j--;
            str3 = ".";
        }
        for (int k = j;; k--)
        {
            if (k < 0)
            {
                if (str2.length() > 0)
                    str3 = str3 + "." + str2;
                return str3;
            }
            if (i == 3)
            {
                str3 = "," + str3;
                i = 0;
            }
            str3 = str1.charAt(k) + str3;
            i++;
        }

    }

    public static String trimCommaOfString(String string) {
//        String returnString;
        if(string.contains(",")){
            return string.replace(",","");}
        else {
            return string;
        }

    }
}

Use This Class on your EditText as follows

editText.addTextChangedListener(new NumberTextWatcherForThousand(editText));

To get the input as plain Double Text

Use the trimCommaOfString method of the same class like this

NumberTextWatcherForThousand.trimCommaOfString(editText.getText().toString())
