我已经实施了一个迷你项目，我需要根据位置显示货币符号。 例如：如果我在印度它应该显示卢比符号如果美国符号，我已经实施但它总是给出英镑符号
我的代码：
LocationManager locationManager = (LocationManager) getSystemService(ListActivity.LOCATION_SERVICE);
Location loc = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
if (loc != null) {
Geocoder code = new Geocoder(ListActivity.this);
try {
List<Address> addresses = code.getFromLocation(loc.getLatitude(), loc.getLongitude(), 1);
Address obj = addresses.get(0);
String cc = Currency.getInstance(obj.getLocale()).getSymbol();
Log.d("Currency Symbol : ", cc);
} catch (IOException e) {
e.printStackTrace();
}
}

我需要显示各自国家的货币符号并获得国家来自GPS我搜索批次最终得出以下代码其工作正常所以我想分享这个代码其他人不能浪费时间
这里你需要第一个国家代码，如IN，US从纬度经度我们得到完整的地址
请在运行代码之前检查清单文件中的GPS权限。 以下是一些权限
需要GPSTracker.java文件代码创建GPSTracker java文件并编写下面的代码。在这一些红线不要担心它什么都不会影响

您可以使用它来获取您的位置的区域设置
Locale locale= getResources().getConfiguration().locale;
Currency currency=Currency.getInstance(locale);
String symbol = currency.getSymbol();
