我想在地图上显示更多点。我想用“for”来做到这一点。我的问题是只显示最后一个点,因为变量:point 和 overlayItem 每次都会被覆盖。我怎样才能为这个变量取一个唯一的名字?
List<Statia> arrStatia = datasourceStatia.getAllStatias();
for (Statia s : arrStatia) {
String[] arrCoordonate = s.getCoord().split(",");
GeoPoint point = new GeoPoint((int)(Double.parseDouble(arrCoordonate[1])),(int)(Double.parseDouble(arrCoordonate[0])));
OverlayItem overlayItem = new OverlayItem(point, Double.parseDouble(arrCoordonate[1]) + "", Double.parseDouble(arrCoordonate[0]) +"");
itemizedOverlay.addOverlay(overlayItem);
mapOverlays.add(itemizedOverlay);
mapView.postInvalidate();
Log.v("xxx", s.getCoord());
}
