public static boolean isCN(Context context) {
    TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
    String countryIso = tm.getSimCountryIso();
    boolean isCN = false;//判断是不是大陆
    if (!TextUtils.isEmpty(countryIso)) {
        countryIso = countryIso.toUpperCase(Locale.US);
        if (countryIso.contains("CN")) {
            isCN = true;
        }
    }
    return isCN;

}

/** 判断是否是国内的 SIM 卡，优先判断注册时的mcc */
public static boolean isChinaSimCard(Context c) {
    String mcc = getSimOperator(c);
    if (isOperatorEmpty(mcc)) {
        return false;
    } else {
        return mcc.startsWith("460");
    }
}

private Location getlocation(Context context) {
LocationManager locationManager = (LocationManager) context.getSystemService(LOCATION_SERVICE);
// gps
@SuppressLint("MissingPermission") Location location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
// 网络定位
@SuppressLint("MissingPermission") Location lastKnownLocation = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
return lastKnownLocation;
}

private void initLoad() {
Location getlocation = getlocation(MyApplication.getContext());
// 获取经纬度
double latitude = getlocation.getLatitude();
double longitude = getlocation.getLongitude();
// 地理编辑器如果想获取地理位置使用地理编辑器将经纬度转换为省市区
Geocoder geocoder = new Geocoder(MyApplication.getContext(), Locale.getDefault());
try {
List<Address> fromLocation = geocoder.getFromLocation(latitude, longitude, 1);
Address address = fromLocation.get(0);
String mAddressLine = address.getAddressLine(0);
Log.i("xxx",mAddressLine.toString());

} catch (IOException e) {
e.printStackTrace();
}
}

Locale locale = Locale.getDefault();
String country = locale.getCountry();

CN 就是中国

1、添加位置权限

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission>

2、activity实现获取经纬度，地理位置代码

public class MainActivity extends AppCompatActivity {

    private TextView textView;

    private static final String[] authBaseArr = {//申请类型
            Manifest.permission.ACCESS_FINE_LOCATION,
            Manifest.permission.ACCESS_COARSE_LOCATION
    };
    private static final int authBaseRequestCode = 1;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        textView = findViewById(R.id.textView);
        LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);

        initNavi();

        //权限检查的代码
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            // TODO: Consider calling

            return;
        }
        locationManager.requestLocationUpdates(
                LocationManager.GPS_PROVIDER,//指定GPS定位提供者
                1000,//指定数据更新的间隔时间
                1,//位置间隔的距离为1m
                new LocationListener() {//监听GPS信息是否改变
                    @Override
                    public void onLocationChanged(Location location) {//GPS信息发送改变时回调
                        Log.i("lgq","onLocationChanged===="+location.getProvider());
                    }

                    @Override
                    public void onStatusChanged(String provider, int status, Bundle extras) {//GPS状态发送改变时回调

                    }

                    @Override
                    public void onProviderEnabled(String provider) { //定位提供者启动时回调

                    }

                    @Override
                    public void onProviderDisabled(String provider) { //定位提供者关闭时回调

                    }
                }
        );
        Location location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);//获取最新的定位信息
        locationUpdates(location);
    }

    private boolean hasBasePhoneAuth() {
        PackageManager pm = getPackageManager();
        for (String auth : authBaseArr) {
            if (pm.checkPermission(auth, getPackageName()) != PackageManager.PERMISSION_GRANTED) {
                return false;
            }
        }
        return true;
    }

    private void initNavi() {
        // 申请权限
        if (android.os.Build.VERSION.SDK_INT >= 23) {
            if (!hasBasePhoneAuth()) {
                this.requestPermissions(authBaseArr, authBaseRequestCode);
                return;
            }
        }
    }



    public void locationUpdates(Location location){

        if(location != null){
            StringBuilder stringBuilder = new StringBuilder(); //构建一个字符串构建器，用于记录定位信息
            stringBuilder.append("您的位置是：\n");
            stringBuilder.append("经度：");
            stringBuilder.append(location.getLongitude());
            stringBuilder.append("\n纬度：");
            stringBuilder.append(location.getLatitude());
            textView.setText(stringBuilder.toString());
            Log.i("lgq",".....经度==="+location.getLongitude()+"...纬度+====="+location.getLatitude());
            String ab = getAddress(location.getLatitude(),location.getLongitude());
            Log.i("lgq","sssssfa===="+ab);
        }
        else{
            textView.setText("GPS失效啦...");
        }
    }

    public String getAddress(double latitude, double longitude) {
        Geocoder geocoder = new Geocoder(this, Locale.getDefault());
        try {
            List<Address> addresses = geocoder.getFromLocation(latitude,
                    longitude, 1);

//            Address[addressLines=[0:"广东省东莞市健升大厦"],feature=健升大厦,admin=广东省,sub-admin=null,locality=东莞市,thoroughfare=null,postalCode=null,countryCode=CN,countryName=中国,hasLatitude=true,
//                    latitude=23.025354,hasLongitude=true,longitude=113.748738,phone=null,url=null,extras=Bundle[mParcelledData.dataSize=92]]
            if (addresses.size() > 0) {
                Address address = addresses.get(0);
                String data = address.toString();
                int startCity = data.indexOf("locality=") + "locality=".length();
                int endCity = data.indexOf(",", startCity);
                String city = data.substring(startCity, endCity);
                int startPlace = data.indexOf("feature=") + "feature=".length();
                int endplace = data.indexOf(",", startPlace);
                String place = data.substring(startPlace, endplace);
                return city + place ;
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        return "获取失败";
    }
}

如获取不到位置信息

加一判断即可

if (location==null){
    locationManager.requestLocationUpdates(
            LocationManager.NETWORK_PROVIDER,//指定GPS定位提供者
            5000,//指定数据更新的间隔时间
            10,//位置间隔的距离为1m
            new LocationListener() {//监听GPS信息是否改变
                @Override
                public void onLocationChanged(Location location) {//GPS信息发送改变时回调
                    Log.i("lgq","onLocationChanged===="+location.getProvider());
                }

                @Override
                public void onStatusChanged(String provider, int status, Bundle extras) {//GPS状态发送改变时回调

                }

                @Override
                public void onProviderEnabled(String provider) { //定位提供者启动时回调

                }

                @Override
                public void onProviderDisabled(String provider) { //定位提供者关闭时回调

                }
            }
    );

    location = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);//获取最新的定位信息
}
