将String转换为Double时无效 [英] Invalid double in converting String to Double
本文介绍了将String转换为Double时无效的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我得到一个NumberFormatException:这行代码中的无效双111,000,000:
i get a NumberFormatException : invalid double "111,000,000" in this line of code :
double SalePotential = Double.valueOf(EtPotential.getText().toString());
在开始我使用了数字格式,格式化我的双值分隔号,并将其插入一个EditText,但是当我尝试检索EditText的值时,它会抛出异常:
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)));
我也尝试过DecimalFormat或Double.parseDouble,没有成功。任何帮助将被欣赏! :
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());
推荐答案
在解析
double SalePotential = Double.parseDouble(EtPotential.getText().toString().replace(",", ""));
更新:正确实现
Update : With proper implementation
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
}
快乐编码:)
Happy coding :)
