我想将美元符号删除到我的金额格式化程序，但它不起作用我已经分配了替换它包含一个美元符号。我怎么能这样做？

这是我的Text Watcher代码。

NumberFormat canadaEnglish = NumberFormat.getCurrencyInstance(Locale.CANADA);
        public class MoneyTextWatcher implements TextWatcher {
        private final WeakReference<EditText> editTextWeakReference;
        boolean hasFractionalPart = false;
        private EditText editText;

        public MoneyTextWatcher(EditText editText) {
            editTextWeakReference = new WeakReference<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) {
            if (s.toString().contains(String.valueOf(df.getDecimalFormatSymbols().getDecimalSeparator()))) {
                hasFractionalPart = true;
            } else {
                hasFractionalPart = false;
            }
            if (mIsInWatcher)
                return;
            mIsInWatcher = true;
        }

        @Override
        public void afterTextChanged(Editable editable) {
            if (editText == null)
                return;
            String s = editable.toString();
            editText.removeTextChangedListener(this);
            String cleanString = s.toString().replaceAll("[$,.]", "");
            String formatted = "";
            System.out.println(cleanString);

                BigDecimal parsed = new BigDecimal(cleanString).setScale(2,BigDecimal.ROUND_FLOOR).divide(new BigDecimal(100),BigDecimal.ROUND_FLOOR);
                formatted = canadaEnglish.format(parsed).replace("\\$",pesoCurrency);
                System.out.println("formatted > " + formatted);
                String trimFormatted = formatted.replace("\\$", pesoCurrency);
                System.out.println("trimFormatted > " + trimFormatted);
                editText.setText(formatted.replace("\\$", ""));
                editText.setSelection(formatted.length());
            editText.addTextChangedListener(this);

        }
    }

Answer 1

试试这个：

String charToReplace = new String[]{"[","$",",",".","]"};

for(String s: charToReplace)
    cleanString = cleanString .replace(s,"");

Answer 2

这是我的MoneyTextWatcher ..感谢响应DroidWorm ..我只需要使用replaceAll（args ..，args ..）从我的edittext中分配文本而不是替换（args ..，args ..）

public static class MoneyTextWatcher implements TextWatcher {

        private EditText editText;

        public MoneyTextWatcher(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 editable) {
            String formatted = "";
            if (editText == null)
                return;
            String s = editable.toString();
            editText.removeTextChangedListener(this);
            String cleanString = s.toString().replaceAll("[\u20B1,]", "");

            System.out.println("cleanString > " + cleanString);
            BigDecimal parsed = new BigDecimal(cleanString.equals("") ? "0.00"
                    : cleanString).setScale(2, BigDecimal.ROUND_FLOOR).divide(
                    new BigDecimal(100), BigDecimal.ROUND_FLOOR);

            formatted = canadaEnglish.format(parsed)
                    .replaceAll("\\$", CURRENCY);

            //System.out.println("formatted > " + formatted);
            editText.setText(formatted.replace("\\$", ""));
            editText.setSelection(formatted.length());
            editText.addTextChangedListener(this);
        }
    }

EditText删除TextWatcher中的货币符号不起作用
