因為專題裡頭用到的資料庫是access，轉換成座標方式
不曉得怎麼轉換，請各位大大幫忙！

以下是程式碼

package tw.edu.foodmap;

public class map extends MapActivity {

Criteria criteria = new Criteria(); //資訊提供者選取標準
bestProvider = mgr.getBestProvider(criteria, true); //選擇精準度最高的提供者
Location location = mgr.getLastKnownLocation(bestProvider);
getLocation(location);
}

private void getLocation(Location location) {
// TODO Auto-generated method stub
Double longitude = location.getLongitude(); //取得經度
Double latitude = location.getLatitude(); //取得緯度
}

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

map = (MapView) findViewById(R.id.map);

//設定一般地圖與衛星地圖
map.setBuiltInZoomControls(true);
map.setSatellite(true);
//縮放設定
mapController =map.getController();
mapController.setZoom(17);
//設定放大倍率1(地球)-21(街道)

//定義經緯度
//GeoPoint point = new GeoPoint(lat.intValue(), lng.intValue());
//OverlayItem overlayitem = new OverlayItem(point, "康家正門", "安安");

List<Overlay> mapOverlays = map.getOverlays();
locmgr = new MyLocationOverlay(this, map);
locmgr.enableMyLocation();

locmgr.runOnFirstFix(new Runnable() {
private String address;
public void run() {
// TODO Auto-generated method stub

mapController.animateTo(locmgr.getMyLocation());

try{
      HttpClient client = new DefaultHttpClient();
      String cmd = "http://163.17.76.16/1/food1.jsp?address" + address;

      String mapAPI = "http://maps.google.com/maps/api/directions/json?origin={0}&destination={1}&language=zh-TW&sensor=true";
HttpGet get = new HttpGet(cmd);
HttpResponse response = client.execute(get);
HttpEntity entity = response.getEntity();
BufferedReader reader = new BufferedReader( new InputStreamReader(entity.getContent()));
String raw,msg="";


      while ((raw = reader.readLine()) != null){

      }
      }catch (Exception ee){

            }
}
});

mapOverlays.add(locmgr);//將定位圖層的圖示加入清單中

}

@Override
protected void onResume() {
// TODO Auto-generated method stub
super.onResume();
Double longitude = location.getLongitude(); //取得經度
Double latitude = location.getLatitude(); //取得緯度



}

@Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
mgr.removeUpdates((LocationListener) this);
}

@Override
protected boolean isRouteDisplayed() {
// TODO Auto-generated method stub
return false;
}

}

把地址丟到 google api 去查詢就好了。
