Android 调用原生API获取地理位置和经纬度，判断所在国家_private location getlocation()

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
}
