我使用的代码如下： - 我的webservice给出了lat，long并在地图上显示的对象数量： - 

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();

我的覆盖类就像那个类一样，Ontap方法整个类就像

一样 
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;
}

请有人建议我如何才能提前实现这个目标..

1 个答案:

答案 0 :(得分：2)

您发送给BidNearItemizedOverlay的View popUp看起来已经有了父级。当你调用addView（popUp，mapParams）时，你试图给它第二个父。这是不允许的。如果您确实想要使用它，则必须先将其与父项分离。最简单的解决方案可能是根据popUp中的属性创建一个新视图，而不是使用该实际视图。

或尝试：

((ViewGroup)popUp.getParent()).removeView(popUp);
