Java 如何根据GPS位置或国家代码获取货币符号
我已经实施了一个小项目,在那里我需要显示基于位置的货币符号。 例:如果我在印度,它应该显示卢比符号,如果是美元符号,我已经实现了,但它总是给出英镑符号 我的代码:Java 如何根据GPS位置或国家代码获取货币符号,java,android,gps,Java,Android,Gps,我已经实施了一个小项目,在那里我需要显示基于位置的货币符号。 例:如果我在印度,它应该显示卢比符号,如果是美元符号,我已经实现了,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
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();
}
}
LocationManager LocationManager=(LocationManager)getSystemService(ListActivity.LOCATION\u服务);
Location loc=locationManager.getLastKnownLocation(locationManager.GPS\U提供程序);
如果(loc!=null){
地理编码器代码=新的地理编码器(ListActivity.this);
试一试{
列表地址=code.getFromLocation(loc.getLatitude(),loc.getLatitude(),1);
地址obj=地址。获取(0);
字符串cc=Currency.getInstance(obj.getLocale()).getSymbol();
日志d(“货币符号:”,cc);
}捕获(IOE异常){
e、 printStackTrace();
}
}
您可以使用它获取您所在位置的区域设置
Locale locale= getResources().getConfiguration().locale;
Currency currency=Currency.getInstance(locale);
String symbol = currency.getSymbol();
参考:我需要显示各自国家的货币符号,并从全球定位系统中获取国家。我搜索了很多,最后找到了下面的代码,它工作正常,所以我想分享这些代码,其他人不能浪费时间
这里您需要第一个国家代码,如在,美国从经纬度,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。 下面是一些权限

上述代码将始终为手机提供语言环境货币。您能建议我如何获取符号..吗?请改为传递当前语言环境,如locale current=getResources().getConfiguration().locale;但这种方法不适用于gps。请参考:这是任何方法,但我需要基于位置、ip或gps显示货币符号。你可以编辑我的代码吗?它给出了£symbol。它应该根据位置显示卢比符号。他没有询问设备的区域设置。他需要一个给定纬度、经度坐标的地区(或国家或货币符号)
