안드로이드에서 모바일 장치의 위도와 경도를 얻는 방법?


위치 도구를 사용하여 Android에서 모바일 장치의 현재 위도와 경도를 얻으려면 어떻게해야합니까?


를 사용하십시오 LocationManager.

LocationManager lm = (LocationManager)getSystemService(Context.LOCATION_SERVICE); 
Location location = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER);
double longitude = location.getLongitude();
double latitude = location.getLatitude();

에 대한 호출 getLastKnownLocation()은 차단되지 않습니다. 즉, null현재 사용 가능한 위치가없는 경우 반환 됩니다. 대신 메소드에 a LocationListener전달 하여 위치를 비동기식으로 업데이트 할 수 있습니다.requestLocationUpdates()

private final LocationListener locationListener = new LocationListener() {
    public void onLocationChanged(Location location) {
        longitude = location.getLongitude();
        latitude = location.getLatitude();
    }
}

lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 2000, 10, locationListener);

GPS를 사용하려면 애플리케이션에 ACCESS_FINE_LOCATION권한 을 부여해야합니다 .

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

GPS를 사용할 수없는 경우 에 대한 ACCESS_COARSE_LOCATION권한 을 추가 하고 getBestProvider()방법으로 위치 제공 업체를 선택할 수도 있습니다 .


다음은 LocationFinderGPS 위치를 찾는 클래스 입니다. 이 클래스는 MyLocation비즈니스를 수행하는 을 (를) 호출 합니다.

public class LocationFinder extends Activity {

    int increment = 4;
    MyLocation myLocation = new MyLocation();

    // private ProgressDialog dialog;

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.intermediat);
        myLocation.getLocation(getApplicationContext(), locationResult);

        boolean r = myLocation.getLocation(getApplicationContext(),
            locationResult);

        startActivity(new Intent(LocationFinder.this,
        // Nearbyhotelfinder.class));
            GPSMyListView.class));
        finish();
    }

    public LocationResult locationResult = new LocationResult() {

함께 google가지 매우 자주 변경 : 나를 위해 일 이전 답변의 비.

2016 년 4 월

이 Google 교육을 바탕으로 사용하는 방법은 다음과 같습니다.

융합 위치 제공자

이를 위해서는 Google Play 서비스 설정이 필요합니다

활동 수업

public class GPSTrackerActivity extends AppCompatActivity implements
    GoogleApiClient.ConnectionCallbacks,     
 GoogleApiClient.OnConnectionFailedListener {

private GoogleApiClient mGoogleApiClient;
Location mLastLocation;

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

    if (mGoogleApiClient == null) {
        mGoogleApiClient = new GoogleApiClient.Builder(this)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .addApi(LocationServices.API)
                .build();
    }

}

protected void onStart() {
    mGoogleApiClient.connect();
    super.onStart();
}

protected void onStop() {
    mGoogleApiClient.disconnect();
    super.onStop();
}

@Override
public void onConnected(Bundle bundle) {
    try {

        mLastLocation = LocationServices.FusedLocationApi.getLastLocation(
                mGoogleApiClient);
        if (mLastLocation != null) {
            Intent intent = new Intent();
            intent.putExtra("Longitude", mLastLocation.getLongitude());
            intent.putExtra("Latitude", mLastLocation.getLatitude());
            setResult(1,intent);
            finish();

        }
    } catch (SecurityException e) {

    }

}

@Override
public void onConnectionSuspended(int i) {

}

@Override
public void onConnectionFailed(ConnectionResult connectionResult) {

}
}

용법

당신의 활동에서

 Intent intent = new Intent(context, GPSTrackerActivity.class);
    startActivityForResult(intent,1);

그리고이 방법

 protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if(requestCode == 1){
        Bundle extras = data.getExtras();
        Double longitude = extras.getDouble("Longitude");
        Double latitude = extras.getDouble("Latitude");
    }
}

이것을 사용하여 Current latlng를 얻을 수 있습니다

             locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
              // Define the criteria how to select the location provider
              criteria = new Criteria();
              criteria.setAccuracy(Criteria.ACCURACY_COARSE);   //default

              // user defines the criteria

              criteria.setCostAllowed(false); 
              // get the best provider depending on the criteria
              provider = locationManager.getBestProvider(criteria, false);

              // the last known location of this provider
              Location location = locationManager.getLastKnownLocation(provider);

              mylistener = new MyLocationListener();

              if (location != null) {
                  mylistener.onLocationChanged(location);
              } else {
                  // leads to the settings because there is no last known location
                  Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
                  startActivity(intent);
              }
              // location updates: at least 1 meter and 200millsecs change
              locationManager.requestLocationUpdates(provider, 200, 1, mylistener);
            String a=""+location.getLatitude();
            Toast.makeText(getApplicationContext(), a, 222).show();

}

private class MyLocationListener implements LocationListener {

      @Override
      public void onLocationChanged(Location location) {
        // Initialize the location fields



          Toast.makeText(MainActivity.this,  ""+location.getLatitude()+location.getLongitude(),
                    Toast.LENGTH_SHORT).show()  

      }

      @Override
      public void onStatusChanged(String provider, int status, Bundle extras) {
          Toast.makeText(MainActivity.this, provider + "'s status changed to "+status +"!",
                    Toast.LENGTH_SHORT).show();
      }

      @Override
      public void onProviderEnabled(String provider) {
          Toast.makeText(MainActivity.this, "Provider " + provider + " enabled!",

위의 솔루션도 정확하지만 위치가 null 인 경우 앱이 중단되거나 제대로 작동하지 않습니다. 안드로이드의 위도 및 경도를 얻는 가장 좋은 방법은 다음과 같습니다.

 Geocoder geocoder;
     String bestProvider;
     List<Address> user = null;
     double lat;
     double lng;

    LocationManager lm = (LocationManager) activity.getSystemService(Context.LOCATION_SERVICE);

     Criteria criteria = new Criteria();
     bestProvider = lm.getBestProvider(criteria, false);
     Location location = lm.getLastKnownLocation(bestProvider);

     if (location == null){
         Toast.makeText(activity,"Location Not found",Toast.LENGTH_LONG).show();
      }else{
        geocoder = new Geocoder(activity);
        try {
            user = geocoder.getFromLocation(location.getLatitude(), location.getLongitude(), 1);
        lat=(double)user.get(0).getLatitude();
        lng=(double)user.get(0).getLongitude();
        System.out.println(" DDD lat: " +lat+",  longitude: "+lng);

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

@ CommonsWare 답변은 나를 위해 일했지만 수정해야했습니다.

public LocationResult locationResult = new LocationResult() {

public MyLocation.LocationResult locationResult = new MyLocation.LocationResult() {

가장 좋은 방법은

권한 매니페스트 파일 추가

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

Then you can get GPS location or if GPS location is not available then this function return NETWORK location

    public static Location getLocationWithCheckNetworkAndGPS(Context mContext) {
    LocationManager lm = (LocationManager)
            mContext.getSystemService(Context.LOCATION_SERVICE);
    assert lm != null;
    isGpsEnabled = lm.isProviderEnabled(LocationManager.GPS_PROVIDER);
    isNetworkLocationEnabled = lm.isProviderEnabled(LocationManager.NETWORK_PROVIDER);

    Location networkLoacation = null, gpsLocation = null, finalLoc = null;
    if (isGpsEnabled)
        if (ActivityCompat.checkSelfPermission(mContext, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(mContext, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

            return null;
        }gpsLocation = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER);
    if (isNetworkLocationEnabled)
        networkLoacation = lm.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);

    if (gpsLocation != null && networkLoacation != null) {

        //smaller the number more accurate result will
        if (gpsLocation.getAccuracy() > networkLoacation.getAccuracy())
            return finalLoc = networkLoacation;
        else
            return finalLoc = gpsLocation;

    } else {

        if (gpsLocation != null) {
            return finalLoc = gpsLocation;
        } else if (networkLoacation != null) {
            return finalLoc = networkLoacation;
        }
    }
    return finalLoc;
}
