解析XML數據到谷歌地圖android

Question

我正在製作一個程序，我必須解析xml數據到谷歌地圖，我知道如何使用xml解析器和谷歌地圖的位知識，在這裏我需要獲取經度，緯度，名稱，並從XML文件地址，需要在谷歌地圖使用標記來顯示，請別人幫我做這個，我把我下面的XML數據： -

<map> 
     <area> 
     <longitude>-97.762914</longitude> 
     <latitude>30.282165</latitude> 
     <name>Place Name 1</name> 
     <address>Place Address 1</address> 
     </area> 
     <area> 
     <longitude>-97.762914</longitude> 
     <latitude>31.282165</latitude> 
     <name>Place Name 3</name> 
     <address>Place Address 3</address> 
     </area> 
     <area> 
     <longitude>-97.762914</longitude> 
     <latitude>32.282165</latitude> 
     <name>Place Name 3</name> 
     <address>Place Address 3</address> 
     </area> 
    </map> 

Answer 1

MapView mapView = new MapView(this, mapkey); 
MapController mc=mapView.getController(); 
GeoPoint myLocation = null; 
Drawable drawable = this.getResources().getDrawable(R.drawable.map_marker); 
myItemizedOverlay itemizedoverlay = new myItemizedOverlay(drawable, this); 
GeoPoint ppoint = new GeoPoint(platt,plngg); //platt and plngg xml parser value lattitude and Longitude 
OverlayItem poverlayitem = new  OverlayItem(ppoint,bankname,name of the place); 
itemizedoverlay.addOverlay(poverlayitem); 
mapOverlays.add(itemizedoverlay); 
myLocation = new GeoPoint(platt,plngg); 
mc.animateTo(myLocation); 
mapView.setBuiltInZoomControls(true); 
mapView.setClickable(true); 
mc.setZoom(14); 
mapView.invalidate(); 
return mapView; 

MyItemizedOverlay類 - >用於在地圖上繪製銷釘

public class myItemizedOverlay extends ItemizedOverlay<OverlayItem> { 

    private ArrayList<OverlayItem> mOverlays = new ArrayList<OverlayItem>(); 
    private Context mContext; 


    public myItemizedOverlay(Drawable defaultMarker) { 
     super(boundCenterBottom(defaultMarker)); 
    } 

    public myItemizedOverlay(Drawable defaultMarker, Context context) { 
      super(boundCenterBottom(defaultMarker)); 
      mContext = context; 
    } 

    public void addOverlay(OverlayItem overlay){ 
     mOverlays.add(overlay); 
     populate(); 
    } 

    @Override 
    protected OverlayItem createItem(int i) { 
     return mOverlays.get(i); 
    } 

    public void removeItem(int i){ 
     mOverlays.remove(i); 
     populate(); 
    } 

    @Override 
    public int size() { 
     return mOverlays.size(); 
    } 

    @Override 
    protected boolean onTap(int i) { 
     OverlayItem item = mOverlays.get(i); 
     AlertDialog.Builder dialog = new AlertDialog.Builder(mContext); 
     dialog.setTitle(item.getTitle()); 
     dialog.setMessage(item.getSnippet()); 
     dialog.show(); 
     return true; 
    }
