我用这代码： - 我的web服务给具有经纬度对象，长的数，显示在地图上为： -
MapController objmapcontroller;
GeoPoint objgeopointp;
double lat, lng;
try {
lat = Double.parseDouble(latitude);
lng = Double.parseDouble(longitude);
} catch (Exception e) {
e.printStackTrace();
lat = lng = 0;
}
objgeopointp = new GeoPoint((int) (lat * 1E6), (int) (lng * 1E6));
objmapcontroller = objmapView.getController();
// ---Add a location marker---
// create and add an OverlayItem to the MyItemizedOverlay list
OverlayItem overlayitem = new OverlayItem(objgeopointp, title, snippet);
itemizedoverlay.addOverlay(overlayitem);
objmapcontroller.animateTo(objgeopointp);
objmapcontroller.setZoom(16);
// add the overlays to the map
mapOverlays.add(itemizedoverlay);
objmapView.invalidate();
而且我覆盖类是在类的Ontap方法全班是
private ArrayList<OverlayItem> mOverlays = new ArrayList<OverlayItem>();
private Context mContext;
private MapView objmapview;
private View popUp;
public BidNearItemizedOverlay(Drawable defaultMarker, Context ctx,MapView objmapview,View popUp) {
super(boundCenterBottom(defaultMarker));
mContext =ctx;
this.objmapview=objmapview;
this.popUp=popUp;
}
public void addOverlay(OverlayItem overlay) {
mOverlays.add(overlay);
populate();
}
public void clear() {
mOverlays.clear();
populate();
}
@Override
protected OverlayItem createItem(int i) {
return mOverlays.get(i);
}
@Override
public int size() {
Log.e("------size--",""+mOverlays.size());
return mOverlays.size();
}
@Override
protected boolean onTap(int index) {
OverlayItem item=getItem(index);
GeoPoint geo=item.getPoint();
MapView.LayoutParams mapParams = new MapView.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT,
geo,
MapView.LayoutParams.BOTTOM_CENTER);
TextView objtxt = (TextView)popUp.findViewById(R.id.textup);
TextView objtxt2 = (TextView)popUp.findViewById(R.id.text2);
objtxt.setText(item.getTitle());
objtxt2.setText(item.getSnippet());
ImageView objimg = (ImageView)popUp.findViewById(R.id.bluebutton);
ImageButton objbtn = (ImageButton)popUp.findViewById(R.id.closebutton);
objbtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
System.out.println("aclosehjdfd");
}
});
objimg.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
System.out.println("hohodshfsdh");
}
});
objmapview.addView(popUp, mapParams);
return true;
}
请任何人建议我如何实现这个目标，在此先感谢..
