Android原生方式获取经纬度

两种定位方式：GPS定位、WiFi定位
优劣：

如果项目定位要求较高还是建议使用三方地图库

GPS定位相比Wifi定位更精准且可在无网络情况下使用，但在室内基本暴毙无法使用
WiFi定位没有室内外限制也不需要开启GPS但需要联网,另外测试发现WiFi定位时onLocationChanged函数（用于监听经纬度变化）触发间隔无法小于30s
   下面是Wifi定位的代码

public class GPSActivity extends AppCompatActivity {
public static final int LOCATION_CODE = 301;
private LocationManager locationManager;
private String locationProvider = null;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getLocation();
}

private void getLocation () {
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
//获取所有可用的位置提供器
List<String> providers = locationManager.getProviders(true);
if (providers.contains(LocationManager.NETWORK_PROVIDER)) {
//如果是Network
locationProvider = LocationManager.NETWORK_PROVIDER;
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
//获取权限（如果没有开启权限，会弹出对话框，询问是否开启权限）
if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED
|| ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
//请求权限
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION,
Manifest.permission.ACCESS_COARSE_LOCATION}, LOCATION_CODE);
} else {
//监视地理位置变化
locationManager.requestLocationUpdates(locationProvider, 3000, 1, locationListener);
Location location = locationManager.getLastKnownLocation(locationProvider);
if (location != null) {
//输入经纬度
Toast.makeText(this, location.getLongitude() + " " + location.getLatitude() + "", Toast.LENGTH_SHORT).show();
}
}
} else {
//监视地理位置变化
locationManager.requestLocationUpdates(locationProvider, 3000, 1, locationListener);
Location location = locationManager.getLastKnownLocation(locationProvider);
if (location != null) {
//不为空,显示地理位置经纬度
Toast.makeText(this, location.getLongitude() + " " + location.getLatitude() + "", Toast.LENGTH_SHORT).show();
}
}
}

public LocationListener locationListener = new LocationListener() {
// Provider的状态在可用、暂时不可用和无服务三个状态直接切换时触发此函数
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
// Provider被enable时触发此函数，比如GPS被打开
@Override
public void onProviderEnabled(String provider) {
}
// Provider被disable时触发此函数，比如GPS被关闭
@Override
public void onProviderDisabled(String provider) {
}
//当坐标改变时触发此函数，如果Provider传进相同的坐标，它就不会被触发
@Override
public void onLocationChanged(Location location) {
if (location != null) {
//不为空,显示地理位置经纬度
Toast.makeText(GPSActivity.this, location.getLongitude() + " " + location.getLatitude() + "", Toast.LENGTH_SHORT).show();
}
}
};

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
switch (requestCode) {
case LOCATION_CODE:
if(grantResults.length > 0 && grantResults[0] == getPackageManager().PERMISSION_GRANTED
&& grantResults[1] == PackageManager.PERMISSION_GRANTED) {
Toast.makeText(this, "申请权限", Toast.LENGTH_LONG).show();
try {
List<String> providers = locationManager.getProviders(true);
if (providers.contains(LocationManager.NETWORK_PROVIDER)) {
//如果是Network
locationProvider = LocationManager.NETWORK_PROVIDER;
}else if (providers.contains(LocationManager.GPS_PROVIDER)) {
//如果是GPS
locationProvider = LocationManager.GPS_PROVIDER;
}
//监视地理位置变化
locationManager.requestLocationUpdates(locationProvider, 3000, 1, locationListener);
Location location = locationManager.getLastKnownLocation(locationProvider);
if (location != null) {
//不为空,显示地理位置经纬度
Toast.makeText(GPSActivity.this, location.getLongitude() + " " + location.getLatitude() + "", Toast.LENGTH_SHORT).show();
}
}catch (SecurityException e){
e.printStackTrace();
}
} else {
Toast.makeText(this, "缺少权限", Toast.LENGTH_LONG).show();
finish();
}
break;
}
}

@Override
protected void onDestroy() {
super.onDestroy();
locationManager.removeUpdates(locationListener);
}
}
别忘记在AndroidManifest.xml加权限

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.INTERNET" />
GPS定位只需更换下面代码

if (providers.contains(LocationManager.GPS_PROVIDER)) {
//如果是GPS
locationProvider = LocationManager.GPS_PROVIDER;
} else if (providers.contains(LocationManager.NETWORK_PROVIDER)) {
//如果是Network
locationProvider = LocationManager.NETWORK_PROVIDER;
} else {
Intent i = new Intent();
i.setAction(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivity(i);
}
