============问题描述============
class MyOverlayItem extends ItemizedOverlay<OverlayItem>
{
private ArrayList<OverlayItem> mOverlayList = new ArrayList<OverlayItem>();
private double mLat1 = 34.0358298501404; // point1纬度
private double mLon1 = 108.7622674067471; // point1经度
private double mLat2 = geoPointList.get(0).getLat();
private double mLon2 = geoPointList.get(0).getLongi();
public MyOverlayItem(Drawable drawable)
{
super(drawable);
GeoPoint geoPoint = new GeoPoint((int)(mLat1 * 1E6), (int)(mLon1 * 1E6));
GeoPoint GeoPointBaidu = CoordinateConvert.fromWgs84ToBaidu(geoPoint);
mOverlayList.add(new OverlayItem(GeoPointBaidu, "point", "point"));
populate();
}
mMapView.getOverlays().add(new MyOverlayItem(drawable));来实现的。求解，纠结了一天了，先谢过了。
