//取得LocationManager实例

LocationManager locationmanager;

String context=Context.LOCATION_SERVICE;

locationmanager=(LocationManager)getSystemService(context);

mymapview=(MapView)findViewById(R.id.map_view);

//取得controller实例，控制地图的缩放

mapcontroller=mymapview.getController();

//设置显示模式

mymapview.setSatellite(true);

mymapview.setStreetView(true);

//实现缩放控制，实现菜单式的控制

mymapview.displayZoomControls(false);

mapcontroller.setZoom(17);

//设置 MyocationOverlay来绘图

myposition =new MyLocationOverlay();

Listoverlays=mymapview.getOverlays();

overlays.add(myposition);

//设置服务商的位置

Criteria criteria=new Criteria();

//经度要求

criteria.setAccuracy(Criteria.ACCURACY_FINE);

criteria.setAltitudeRequired(false);

criteria.setBearingRequired(false);

criteria.setCostAllowed(false);

criteria.setPowerRequirement(Criteria.POWER_LOW);

//取得效果最好的criteria

String provider=locationmanager.getBestProvider(criteria,

true);
