android之GPS

获取所在地的经纬度信息:
代码如下:


public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        LocationManager lm;

        Location loc;

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

        loc = lm.getLastKnownLocation(lm.GPS_PROVIDER); //获取location信息

        if(loc != null){

        double x,y;

        x = loc.getLatitude();  //获取纬度

        y = loc.getLongitude(); //获取经度

        System.out.print(x);

        System.out.println(y);

      

        int i = (int) (loc.getLatitude() * 1E6);

        int j = (int) (loc.getLongitude() * 1E6);

        System.out.print(i+"~~~~");

        System.out.println(-j); //我的所在地的经度为负值,我想输出的为正值,故取反   

        }
