1.动态获取经纬度权限
2.获取经纬度:根据 LocationManager NETWORK_PROVIDER,GPS_PROVIDER,PASSIVE_PROVIDER 去获取
public static void getLocation(final ICallback callback) {
if (ActivityCompat.checkSelfPermission(CCApplication.getInstance(), Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED
&& ActivityCompat.checkSelfPermission(CCApplication.getInstance(), Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
if (callback != null) {
callback.onError(new Throwable("no permission"));
}
return;
}
String mLocationProvider;
final LocationManager locationManager = (LocationManager) CCApplication.getInstance().getSystemService(Context.LOCATION_SERVICE);
if (locationManager == null) {
if (callback != null) {
callback.onError(new Throwable("locationManager null"));
}
return;
}
List providers = locationManager.getProviders(true);
LocationListener locationListener = new LocationListener() {
@Override
public void onLocationChanged(Location location) {
// updateLocation(location, callback);
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
@Override
public void onProviderEnabled(String provider) {
}
@Override
public void onProviderDisabled(String provider) {
}
};
if (providers == null || providers.isEmpty()) {
if (callback != null) {
callback.onError(new Throwable("providers null"));
}
return;
}
if (providers.contains(LocationManager.NETWORK_PROVIDER)) {
locationManager.requestSingleUpdate(LocationManager.NETWORK_PROVIDER, locationListener, null);
mLocationProvider = LocationManager.NETWORK_PROVIDER;
} else if (providers.contains(LocationManager.GPS_PROVIDER)) {
locationManager.requestSingleUpdate(LocationManager.GPS_PROVIDER, locationListener, null);
mLocationProvider = LocationManager.GPS_PROVIDER;
} else if (providers.contains(LocationManager.PASSIVE_PROVIDER)) {
locationManager.requestSingleUpdate(LocationManager.PASSIVE_PROVIDER, locationListener, null);
mLocationProvider = LocationManager.PASSIVE_PROVIDER;
} else {
if (callback != null) {
callback.onError(new Throwable("providers contains null"));
}
return;
}
Location location = locationManager.getLastKnownLocation(mLocationProvider);
updateLocation(location, callback);
}
public static void updateLocation(Location location, final ICallback callback) {
if (location == null) {
if (callback != null) {
callback.onError(new Throwable("location null"));
}
return;
}
double latitude = location.getLatitude();
double longitude = location.getLongitude();
Log.i(TAG, "latitude : " + latitude + " longitude : " + longitude);
getAddress(latitude, longitude, callback);
}
3.根据经纬度去解析具体位置:主要是Geocoder-->getFromLocation
public static void getAddress(double latitude, double longitude, final ICallback callback) {
Geocoder geocoder = new Geocoder(CCApplication.getInstance(), Locale.ENGLISH);
try {
List addresses = geocoder.getFromLocation(latitude, longitude, 1);
Address address = addresses != null && addresses.size() > 0 ? addresses.get(0) : null;
if (address != null) {
String countryName = address.getCountryName();
String countryCode = address.getCountryCode();
Log.i(TAG, "countryName : " + countryName + " countryCode : " + countryCode);
if (callback != null) {
callback.onResult(new LocationBean(latitude, longitude, countryName, countryCode, address.toString()));
}
} else {
if (callback != null) {
callback.onError(new Throwable("address null"));
}
}
} catch (IOException e) {
e.printStackTrace();
if (callback != null) {
callback.onError(e);
}
}
}
