android给EditText加金额的属性，带元，角和分，如￥12.34

功能如标题，代码如下：  (本代码

可直接用到你的项目中，

只需要将EditText transactionMoney替换成你的即可)

      String abc = "";
      EditText transactionMoney;//就是随便一个输入框，表示金额
   //下面就是给editText加一个文字监听

transactionMoney.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) {
    }

    @Override
    public void afterTextChanged(Editable s) {
        if (!s.toString().equals(abc)) {
            transactionMoney.removeTextChangedListener(this);
            String replaceable = String.format("[%s, \s.]", NumberFormat.getCurrencyInstance(Locale.CHINA).getCurrency().getSymbol(Locale.CHINA));
            String cleanString = s.toString().replaceAll(replaceable, "");

            if (cleanString.equals("") || new BigDecimal(cleanString).toString().equals("0")) {
                transactionMoney.setText(null);
            } else {
                double parsed = Double.parseDouble(cleanString);
                String formatted = NumberFormat.getCurrencyInstance(Locale.CHINA).format((parsed / 100));
                abc = formatted;
                transactionMoney.setText(formatted);
                transactionMoney.setSelection(formatted.length());
            }
            transactionMoney.addTextChangedListener(this);
        }
    }
});

          希望对您有所帮助！
