EditText 动态输入千分位逗号

通过设置TextWatcher监听，每次SetText之后，会重新调用afterTextChanged , 因此要每次进行判断，反正造成死循环。

 EditText.addTextChangedListener(new TextWatcher() {
            DecimalFormat df = new DecimalFormat(",###");
            String oldValue = "";

            @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) {
                String money = s.toString().replace(",", "");
                if (!oldValue.equals(money)) {
                    oldValue = money;
                    if (!StringUtils.isEmpty(money)) {
                        String formatMoney = df.format(Integer.valueOf(money));
                        etTelSendMoeny.setText(formatMoney);
                        if (s.toString().length() != 0) {
                            etTelSendMoeny.setSelection(formatMoney.length());
                        }
                    } else {
                        etTelSendMoeny.setText("");
                    }
                }
            }
        });
