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，

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);

4000
} 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！
