我希望获取设备的国家代码，而不使用sim卡。
例如：如果国家是斯里兰卡，则国家代码为LK。
我的最终目标是获取拨打代码（斯里兰卡为+94）。
我尝试使用以下方法：
TelephonyManager tm = (TelephonyManager)this.getSystemService(getApplicationContext().TELEPHONY_SERVICE);
String countryCodeValue = tm.getNetworkCountryIso();
Locale current = getResources().getConfiguration().locale;
但这并不一定与查看运营商iso得到的结果相同，用户可以在设置中随时更新到任何他们想要的内容。正如所指出的那样，您还可以向位置管理器请求用户的坐标。但请记住，用户会移动，他们当前的位置可能并不总是对应其运营商的iso。
以下是一个完整的例子。尝试从TelephonyManager中获取国家代码（从SIM卡或CDMA设备），如果不可用，则尝试从本地配置中获取。
private static String getDeviceCountryCode(Context context) {
String countryCode;
// try to get country code from TelephonyManager service
TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
if(tm != null) {
// query first getSimCountryIso()
countryCode = tm.getSimCountryIso();
if (countryCode != null && countryCode.length() == 2)
return countryCode.toLowerCase();
if (tm.getPhoneType() == TelephonyManager.PHONE_TYPE_CDMA) {
// special case for CDMA Devices
countryCode = getCDMACountryIso();
} else {
// for 3G devices (with SIM) query getNetworkCountryIso()
countryCode = tm.getNetworkCountryIso();
}
if (countryCode != null && countryCode.length() == 2)
return countryCode.toLowerCase();
}
// if network country not available (tablets maybe), get country code from Locale class
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
countryCode = context.getResources().getConfiguration().getLocales().get(0).getCountry();
} else {
countryCode = context.getResources().getConfiguration().locale.getCountry();
}
if (countryCode != null && countryCode.length() == 2)
return countryCode.toLowerCase();
// general fallback to "us"
return "us";
}
@SuppressLint("PrivateApi")
private static String getCDMACountryIso() {
try {
// try to get country code from SystemProperties private class
Class<?> systemProperties = Class.forName("android.os.SystemProperties");
Method get = systemProperties.getMethod("get", String.class);
// get homeOperator that contain MCC + MNC
String homeOperator = ((String) get.invoke(systemProperties,
"ro.cdma.home.operator.numeric"));
// first 3 chars (MCC) from homeOperator represents the country code
int mcc = Integer.parseInt(homeOperator.substring(0, 3));
// mapping just countries that actually use CDMA networks
switch (mcc) {
case 330: return "PR";

为了获取国家前缀，您可以使用Google的LibPhoneNumber库。
您可以使用此http://maps.googleapis.com/maps/api/geocode/json?latlng=7.0000,81.0000&sensor=false来获取国家代码。缩写将为您提供国家代码。
public void getAddress(double lat,double lng) {
Address1 = "";
Address2 = "";
City = "";
State = "";
Country = "";
County = "";
PIN = "";
try {
JSONObject jsonObj = JsonParser.getJSONfromURL("http://maps.googleapis.com/maps/api/geocode/json?latlng=" + lat + ","
+lng + "&sensor=false");
String Status = jsonObj.getString("status");
if (Status.equalsIgnoreCase("OK")) {
JSONArray Results = jsonObj.getJSONArray("results");
JSONObject zero = Results.getJSONObject(0);
JSONArray address_components = zero.getJSONArray("address_components");
for (int i = 0; i < address_components.length(); i++) {
JSONObject zero2 = address_components.getJSONObject(i);
String long_name = zero2.getString("long_name");
String short_name = zero2.getString("short_name");
JSONArray mtypes = zero2.getJSONArray("types");
String Type = mtypes.getString(0);
if (TextUtils.isEmpty(long_name) == false || !long_name.equals(null) || long_name.length() > 0 || long_name != "") {
if (Type.equalsIgnoreCase("street_number")) {
Address1 = long_name + " ";
} else if (Type.equalsIgnoreCase("route")) {
Address1 = Address1 + long_name;
} else if (Type.equalsIgnoreCase("sublocality")) {
Address2 = long_name;
} else if (Type.equalsIgnoreCase("locality")) {
// Address2 = Address2 + long_name + ", ";
City = long_name;
} else if (Type.equalsIgnoreCase("administrative_area_level_2")) {
County = long_name;
} else if (Type.equalsIgnoreCase("administrative_area_level_1")) {
State = long_name;
} else if (Type.equalsIgnoreCase("country")) {
Country = short_name;
} else if (Type.equalsIgnoreCase("postal_code")) {
PIN = long_name;
}
}
// JSONArray mtypes = zero2.getJSONArray("types");
// String Type = mtypes.getString(0);
// Log.e(Type,long_name);
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
但是你需要获取当前的纬度和经度..
使用此链接获取当前的纬度和经度
&key=...。 - Jesse ChisholmtelephonyManager.getNetworkCountryIso() 返回为空，因为我有两个 SIM 卡插槽，如果它返回 ""，你可以将插槽作为参数传递。只需更改您的代码如下： String iso=telephonyManager.getNetworkCountryIso();
if(TextUtils.isEmpty(iso))
iso=telephonyManager.getNetworkCountryIso(1);
if(TextUtils.isEmpty(iso))
iso=telephonyManager.getNetworkCountryIso(2);
// this code will give preference to Sim Slot 1
