百度地图3.7.1添加覆盖物

首先应该请求网络得到一些信息，比如要添加覆盖物的经度纬度，介绍啊之类的，然后就是怎么来添加覆盖物了。

private void addMarker(List<Info> infos) {
        //清掉地图上的图层
        mBaidu.clear();
        LatLng la = null;
        //声明覆盖物
        Marker marker = null;
        //覆盖层对象
        OverlayOptions options = null;
        for (Info info : infos) {
            la = new LatLng(info.getLatitude(), info.getLongitude());
            //设置覆盖层的经纬，和图标，和底基层
            options = new MarkerOptions().icon(mMarker).position(la).zIndex(5);
            //加入层
            marker = (Marker) mBaidu.addOverlay(options);
            //传递值，为了点击事件
            Bundle b = new Bundle();
            b.putSerializable("info",info);
            marker.setExtraInfo(b);
        }
        //设置地图到最后一个位置
        MapStatusUpdate msu = MapStatusUpdateFactory.newLatLng(la);
        mBaidu.setMapStatus(msu);
    }

点击事件

mBaidu.setOnMarkerClickListener(new OnMarkerClickListener() {
            
            @Override
            public boolean onMarkerClick(Marker marker) {
                Bundle extraInfo = marker.getExtraInfo();
                Info info = (Info) extraInfo.getSerializable("info");
                ImageView iv = (ImageView) mMarkerLy
                        .findViewById(R.id.id_info_img);
                TextView distance = (TextView) mMarkerLy
                        .findViewById(R.id.id_info_distance);
                TextView name = (TextView) mMarkerLy
                        .findViewById(R.id.id_info_name);
                TextView zan = (TextView) mMarkerLy
                        .findViewById(R.id.id_info_zan);
                iv.setImageResource(info.getImgId());
                distance.setText(info.getDistance());
                name.setText(info.getName());
                zan.setText(info.getZan() + "");
                mMarkerLy.setVisibility(View.VISIBLE);
                
                return true;
            }
        });
    //地图点击事件
        mBaidu.setOnMapClickListener(new OnMapClickListener() {
            
            @Override
            public boolean onMapPoiClick(MapPoi arg0) {
                // TODO Auto-generated method stub
                return false;
            }
            
            @Override
            public void onMapClick(LatLng arg0) {
                mMarkerLy.setVisibility(View.GONE);
                //隐藏
                mBaidu.hideInfoWindow();
                
            }
        });
