Bagaimana cara mendapatkan Latitude dan Longitude dari perangkat seluler di android?

Bagaimana cara mendapatkan Latitude dan Longitude saat ini dari perangkat seluler di android menggunakan alat lokasi?

Gunakan LocationManager.

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

Panggilan untuk getLastKnownLocation()tidak memblokir - yang berarti itu akan kembali nulljika tidak ada posisi yang saat ini tersedia - sehingga Anda mungkin ingin memiliki melihat melewati LocationListenerke requestLocationUpdates()metode sebagai gantinya, yang akan memberikan update asynchronous lokasi Anda.

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);

Anda harus memberikan ACCESS_FINE_LOCATIONizin kepada aplikasi Anda jika Anda ingin menggunakan GPS.

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

Anda juga mungkin ingin menambahkan ACCESS_COARSE_LOCATIONizin ketika GPS tidak tersedia dan pilih penyedia lokasi Anda dengan getBestProvider()metode ini .

Inilah kelas LocationFinderuntuk menemukan lokasi GPS. Kelas ini akan memanggil MyLocation, yang akan melakukan bisnis.

Dengan googlehal-hal yang sangat sering berubah: tidak ada jawaban sebelumnya yang berhasil untuk saya.

berdasarkan pelatihan google ini di sini adalah bagaimana Anda menggunakannya

penyedia lokasi menyatu

ini memerlukan Set Up Google Play Services

Kelas aktivitas

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) {

}
}

pemakaian

dalam aktivitas Anda

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

Dan metode ini

 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");
    }
}

Anda bisa mendapatkan latlng sekarang menggunakan ini

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

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

              // the last known location of this provider

                  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();

}

Solusi di atas juga benar, tetapi beberapa waktu jika lokasi nol maka aplikasi crash atau tidak berfungsi dengan baik. Cara terbaik untuk mendapatkan Latitude dan Longitude dari android adalah:

 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();
        }
    }

Cara terbaik adalah

Tambahkan file manifes izin

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

Kemudian Anda bisa mendapatkan lokasi GPS atau jika lokasi GPS tidak tersedia maka fungsi ini mengembalikan lokasi NETWORK

    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;
}

Tambahkan String untuk dialog peringatan jika GPS dinonaktifkan

   <string name="title_enable_gps">Enable GPS</string>
   <string name="desc_enable_gps">GPS is not enabled. Do you want to go to settings menu?</string>
    <string name="btn_settings">Open Settings</string>
