是的,Android设备可以在没有互联网连接的情况下获取位置地址。这可以通过使用Android的位置服务和离线地图数据来实现。下面是一个使用离线地图数据获取位置地址的示例代码:
首先,在你的Android项目中添加以下依赖项:
implementation 'com.google.android.gms:play-services-location:17.0.0'
implementation 'com.mapbox.mapboxsdk:mapbox-android-sdk:9.6.1'
implementation 'com.mapbox.mapboxsdk:mapbox-android-plugin-places:0.12.0'
然后,在你的Activity或Fragment中使用以下代码获取位置地址:
import android.location.Address;
import android.location.Geocoder;
import android.location.Location;
import android.os.Bundle;
import android.widget.Toast;
import androidx.annotation.NonNull;
import androidx.appcompat.app.AppCompatActivity;
import com.google.android.gms.location.FusedLocationProviderClient;
import com.google.android.gms.location.LocationCallback;
import com.google.android.gms.location.LocationResult;
import com.google.android.gms.location.LocationServices;
import com.mapbox.mapboxsdk.Mapbox;
import com.mapbox.mapboxsdk.maps.MapView;
import com.mapbox.mapboxsdk.maps.OnMapReadyCallback;
import com.mapbox.mapboxsdk.maps.Style;
import com.mapbox.mapboxsdk.plugins.places.autocomplete.PlaceAutocomplete;
import com.mapbox.mapboxsdk.plugins.places.autocomplete.model.PlaceOptions;
import java.io.IOException;
import java.util.List;
import java.util.Locale;
public class MainActivity extends AppCompatActivity implements OnMapReadyCallback {
private MapView mapView;
private FusedLocationProviderClient fusedLocationClient;
private LocationCallback locationCallback;
private Geocoder geocoder;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Mapbox.getInstance(this, "YOUR_MAPBOX_ACCESS_TOKEN");
setContentView(R.layout.activity_main);
mapView = findViewById(R.id.mapView);
mapView.onCreate(savedInstanceState);
mapView.getMapAsync(this);
fusedLocationClient = LocationServices.getFusedLocationProviderClient(this);
geocoder = new Geocoder(this, Locale.getDefault());
locationCallback = new LocationCallback() {
@Override
public void onLocationResult(LocationResult locationResult) {
if (locationResult != null) {
Location location = locationResult.getLastLocation();
if (location != null) {
getAddressFromLocation(location.getLatitude(), location.getLongitude());
}
}
}
};
startLocationUpdates();
}
private void startLocationUpdates() {
fusedLocationClient.requestLocationUpdates(LocationRequest.create(), locationCallback, null);
}
private void getAddressFromLocation(double latitude, double longitude) {
try {
List addresses = geocoder.getFromLocation(latitude, longitude, 1);
if (addresses != null && addresses.size() > 0) {
Address address = addresses.get(0);
String addressLine = address.getAddressLine(0);
// 在这里处理获取到的地址信息
Toast.makeText(this, addressLine, Toast.LENGTH_SHORT).show();
}
} catch (IOException e) {
e.printStackTrace();
}
}
@Override
public void onMapReady(@NonNull final com.mapbox.mapboxsdk.maps.MapboxMap mapboxMap) {
mapboxMap.setStyle(Style.MAPBOX_STREETS, new Style.OnStyleLoaded() {
@Override
public void onStyleLoaded(@NonNull Style style) {
// 在此处设置地图样式和其他地图相关的操作
}
});
}
@Override
public void onStart() {
super.onStart();
mapView.onStart();
}
@Override
public void onResume() {
super.onResume();
mapView.onResume();
}
@Override
public void onPause() {
super.onPause();
mapView.onPause();
}
@Override
public void onStop() {
super.onStop();
mapView.onStop();
}
@Override
public void onDestroy() {
super.onDestroy();
mapView.onDestroy();
fusedLocationClient.removeLocationUpdates(locationCallback);
}
@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
mapView.onSaveInstanceState(outState);
}
}
以上代码中,你需要将"YOUR_MAPBOX_ACCESS_TOKEN"替换为你自己的Mapbox访问令牌。此外,还需要在布局文件中添加一个MapView元素:
这样,你就可以在没有互联网连接的情况下获取设备的位置地址了
