在将字符串转换为Double双无效 [英] Invalid double in converting String to Double

问题描述

我得到一个NumberFormatException异常：无效的双111,000,000在此行中code的：

 双SalePotential = Double.valueOf（EtPotential.getText（）的toString（））;
 

在我使用NUMBERFORMAT，格式化我的双重价值分离号并将其插入到一个EditText但是当我尝试检索的EditText的值，它抛出我异常的开头：

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

我也试过DecimalFormat的或者Double.parseDouble没有成功。任何帮助，将鸭preciated！

  DecimalFormat的F =新的DecimalFormat（### ###，DecimalFormatSymbols.getInstance（））;
双SalePotential = Double.parseDouble（EtPotential.getText（）的toString（））;
 

解决方案

解析之前删除，

 双SalePotential = Double.parseDouble（EtPotential.getText（）的toString（）代替（，））;
 

---

更新：通过适当的执行

 双SalePotential = 0;
        尝试{
            SalePotential = Double.parseDouble（EtPotential.getText（）的toString（）代替（，））;
        }赶上（NumberFormatException的E）{
            //的EditText EtPotential不包含有效的双
        }
 

快乐编码：）的

i get a NumberFormatException : invalid double "111,000,000" in this line of code :

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

in the beginning i've used Numberformat , to format my double value for separating number and inserted it to an EditText but when i try to retrieve the value of EditText it throws me the exception :

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

i've also tried DecimalFormat or Double.parseDouble with no Success. any help would be Appreciated! :

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

解决方案

Remove "," before parsing

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

---

Update : With proper implementation

double SalePotential = 0;
        try {
            SalePotential = Double.parseDouble(EtPotential.getText().toString().replace(",", ""));
        } catch (NumberFormatException e) {
            // EditText EtPotential does not contain a valid double
        }

Happy coding :)
