android - 将 String 转换为 Double 时无效的 double

Question

我得到一个 NumberFormatException : invalid double "111,000,000"in this line of code :

double SalePotential = Double.valueOf(EtPotential.getText().toString());

一开始我使用 Numberformat 来格式化我的 double 值以分隔数字并将其插入到 EditText 但是当我尝试检索 EditText 的值时它抛出异常:

NumberFormat f = NumberFormat.getInstance();
EtPotential.setText(String.valueOf(f.format(PTData.SalePotential)));

我也试过 DecimalFormat 或 Double.parseDouble 但没有成功。任何帮助，将不胜感激! :

DecimalFormat f = new DecimalFormat("###.###", DecimalFormatSymbols.getInstance());
double SalePotential = Double.parseDouble(EtPotential.getText().toString());

Answer 1

解析前去掉“,”

double SalePotential = Double.parseDouble(EtPotential.getText().toString().replace(",", ""));

---

更新:正确实现

double salePotential = 0; // Variable name should start with small letter 
try {
    salePotential = Double.parseDouble(EtPotential.getText().toString().replace(",", ""));
} catch (NumberFormatException e) {
    // EditText EtPotential does not contain a valid double
}

编码愉快 :)
