更改DecimalFormat语言环境 [英] Change DecimalFormat locale

问题描述

我在Edittext的addTextChangedListener方法中具有自定义DecimalFormat，一切正常，但是当我更改语言(语言环境)时，我的addTextChangedListener无法正常工作.

I have custom DecimalFormat in Edittext's addTextChangedListener method, everything is working perfectly but when I change language (locale) my addTextChangedListener is not working.

double answer = inputDouble * counterToDouble;
DecimalFormat df = new DecimalFormat("##.########");
// df=(DecimalFormat)numberFormat;

df.setRoundingMode(RoundingMode.DOWN);
answer = Double.parseDouble(df.format(answer));

unicoinsAmmount.setText(String.valueOf(df.format(answer)));

我搜索了自己的问题，并找到了NumberFormat解决方案:

I searched about my problem and found a NumberFormat solution:

NumberFormat numberFormat = NumberFormat.getNumberInstance(Locale.US);

但是我不知道如何使用此代码.

but I don't know how I can use this code.

推荐答案

您可以尝试先转换为NumberFormat，然后将其转换为DecimalFormat

You may try by first converting to NumberFormat and then Cast it to DecimalFormat

Integer vc = 3210000;
NumberFormat nf = NumberFormat.getNumberInstance(Locale.US);
DecimalFormat formatter = (DecimalFormat) nf;
formatter.applyPattern("#,###,###");
String fString = formatter.format(vc);
return convertNumbersToEnglish(fString);
