区域设置独立的字符串翻番 [英] Locale independent String to double
问题描述
在我的应用程序,我有编辑文本框,用户输入的应用程序使用运行计算的十进制数。
In my app, I have edit text boxes where the user enters a decimal value that the app uses to run a calculation.
在其他区域设置一些用户输入数字时,如入值和不同的一个报告中出现的问题。我试图通过获得来自EDITTEXT值用这种方法来解决这个问题:
Some users in other locales are reporting problems when entering the numbers, like entering a value and a different one appearing. I have tried to fix this by getting the value from the editText with this method:
public double stringToDouble(String s){
if (nf == null){
nf = NumberFormat.getInstance(Locale.US);
}
try {
return nf.parse(s).doubleValue();
} catch (ParseException e) {
e.printStackTrace();
return 0.0;
}
}
和
val = stringToDouble(et.getText().toString());
但显然仍是不工作的一些人。
But apparently that still isn't working for some people.
在斯洛文尼亚的一位用户报告说,它工作正常,如果
One user in Slovenia reported that it works fine if
- 设置;语言和放大器;键盘:
- 选择语言:设置为英语(斯洛文尼亚)
- 触摸输入:只有设置为英语和任何语言(我的情况 斯洛文尼亚)
- 双语prediction:OFF
- 正文prediction:OFF
- settings; Language & keyboard :
- Select language : set to English(Slovenia)
- Touch input: set only to English and whatever language(my case Slovenia)
- Bilingual prediction: OFF
- Text prediction: OFF
什么是去获取的双重价值的正确方法是什么? 谢谢
What is the correct way to go about fetching the double values? Thanks
推荐答案
从外观上来看,做正确的做法是:
From the looks of it, the correct way to do it is:
public double stringToDouble(String s){
if (nf == null){
nf = NumberFormat.getInstance(Locale.getDefault());
}
try {
return nf.parse(s).doubleValue();
} catch (ParseException e) {
e.printStackTrace();
return 0.0;
}
}
到目前为止,这似乎是为我工作。
So far that seems to be working for me.
