arcgis android之定位功能的示例代碼

  private double lat=-1;//緯度
  private double lon=-1;//經(jīng)度
 public class MainActivity extends ActivityBas{

  dingweilocation()；
  mapView.centerAt(lat, lon, true);//設(shè)置定位中心點(diǎn)
  mapView.setScale(1105828.1803422251);//設(shè)置顯示比例
  }

private void dingweilocation() {

        Log.i("定位",lat+"?"+lon);
        lat = location.getLatitude();//緯度
