Android : GMS 패키지없이 위도와 경도를 얻는 방법

Question

GMS 패키지없이 위도와 경도를 얻는 방법은 모바일 네트워크를 사용할 수 있지만 gms 패키지가 있습니다.

Answer 1

GSM 패키지가없는 경우 전체 코드 아래의 위치 사용에 위도와 경도를 얻을 수 있습니다. 그것의 작동 코드.

GPSTrackingActivity.java

public class GPSTrackingActivity extends Activity { 

    Button btnShowLocation; 

    // GPSTracker class 
    GPSTracker gps; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 

     btnShowLocation = (Button) findViewById(R.id.btnShowLocation); 

     // show location button click event 
     btnShowLocation.setOnClickListener(new View.OnClickListener() { 

      @Override 
      public void onClick(View arg0) {   
       // create class object 
       gps = new GPSTracker(GPSTrackingActivity.this); 

       // check if GPS enabled  
       if(gps.canGetLocation()){ 

        double latitude = gps.getLatitude(); 
        double longitude = gps.getLongitude(); 

        // \n is for new line 
        Toast.makeText(getApplicationContext(), "Your Location is - \nLat: " + latitude + "\nLong: " + longitude, Toast.LENGTH_LONG).show();  
       }else{ 
        // can't get location 
        // GPS or Network is not enabled 
        // Ask user to enable GPS/network in settings 
        gps.showSettingsAlert(); 
       } 

      }
