在这里，我必须显示货币小数分隔符和千位分隔符，根据给定的输入，如：

private var decimalSeparator: Char = '.'
    private var thousandSeparator: String = ","

    fun setDecimalSeparator(decimalSeparator: Char) {
        this.decimalSeparator = decimalSeparator
    }

    fun setThousandSeparator(thousandSeparator: String) {
        this.thousandSeparator = thousandSeparator
    }

我还为编辑文本字段添加了文本监视器，以便在Add comma as thousands separator for numbers in EditText for Android Studio?的帮助下添加相应的小数点和千位分隔符，如下所示

field.addTextChangedListener(object : TextWatcher {

            override fun afterTextChanged(p0: Editable?) {
                Log.d("CharCount:", p0.toString().length.toString())
                field.removeTextChangedListener(this)

                try {
                    var givenstring: String = p0.toString()
                    if (givenstring.contains(thousandSeparator)) {
                        givenstring = givenstring.replace(thousandSeparator.toRegex(), "")
                    }
                    val longVal: Long = givenstring.toLong()
                    val formatter = DecimalFormat("#$thousandSeparator###$thousandSeparator###")
                    val formattedString = formatter.format(longVal)
                    field.setText(formattedString)
                    field.setSelection(field.text.length)
                    // to place the cursor at the end of text
                } catch (nfe: NumberFormatException) {
                    nfe.printStackTrace()
                } catch (e: Exception) {
                    e.printStackTrace()
                }

                field.addTextChangedListener(this)

            }

            override fun beforeTextChanged(p0: CharSequence?, p1: Int, p2: Int, p3: Int) {
                // no need any callback for this.
            }

            override fun onTextChanged(p0: CharSequence?, p1: Int, p2: Int, p3: Int) {
                // no need any callback for this.
            }

        })

当thousandSeparator为句点（.）时，此选项不起作用;有谁能帮我一下吗？先谢谢了
