[問題] 在mapView上click並觸發事件

[Ghamu (貓丸)]

各位版友好~

小弟想請問一下這個問題

我想要達到的功能是這樣

用GPS定位抓到現在的位置並顯示地圖

然後在地圖上click

觸發事件之後在click的點上新增一個標籤tag在上面

嗯嗯

是說我現在竟然連click顯示個吐司都沒辦法..

不知道哪裡有問題

public class Part14_MapActivity extends MapActivity implements
LocationListener {
    /** Called when the activity is first created. */
    private MapView map;
    private MapController mapCtrl;
    private MyLocationOverlay myPoint;
    private LocationManager mgr;
    private String bestProv;


    /*public enum BasePoint
    {
        TOP_LEFT,TOP_CENTER,TOP_RIGHT,MIDDLE_LEFT,MIDDLE_CENTER,MIDDLE_RIGHT,
        BOTTOM_LEFT,BOTTOM_CENTER,BOTTOM_RIGHT
    }*/

        @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        //setViews();
        setMap(25.019943,121.542553);
    }

............

private void setMap(double dlat,double dlon)
    {
        map=(MapView)findViewById(R.id.map);
        map.setBuiltInZoomControls(true);
        map.setSatellite(false);
        mapCtrl=map.getController();
        mapCtrl.setZoom(18);

        //////setup overlay function
        List<Overlay> mapOverlays=map.getOverlays();//get overlay container of
map
        OverlayItem item;
        Drawable pic;
        MapItemlizedOverlay mOverlay;
        GeoPoint point;



        pic=getResources().getDrawable(R.drawable.ic_launcher);//ic_launcher is
just a pic default in res
        pic.setBounds(-pic.getMinimumWidth()/2, -pic.getMinimumHeight()/2,
pic.getMinimumWidth()/2,pic.getMinimumHeight()/2);
        ///
        pic.setAlpha(100);
        mOverlay=new MapItemlizedOverlay(pic,this);//set default tag pic and
context
        point=new GeoPoint((int)(dlat*1e6),(int)(dlon*1e6));
        item=new OverlayItem(point,"台北市","天龍國");
        mOverlay.addOverlay(item);
        mapOverlays.add(mOverlay);


        //GPS2
        mgr=(LocationManager)getSystemService(LOCATION_SERVICE);
        Criteria c=new Criteria();
        bestProv=mgr.getBestProvider(c, true);

        map.setOnLongClickListener(new View.OnLongClickListener(){


                        public boolean onLongClick(View arg0) {
                                // TODO Auto-generated method stub
                                Toast.makeText(Part14_MapActivity.this, "ahhhhhhhh",100000).show();
                                Log.d("ahhhh","ffffffffff");
                                return false;
                        }
        });


......

不知道是哪出了問題....

連log都不知道在哪.....
