我想繪製地圖上的一些geepoints之間的路徑,同時我通過geopoints的數組列表迭代。從這我收到索引超出界限的錯誤,我累了調試它,但沒有得到任何地方。那麼請有人指出我正確的方向,並感謝你。使用地圖疊加和GeoPoints在地圖視圖上的Android繪圖路徑
//making the array and inserting the geopoints
List <GeoPoint> points = new ArrayList<GeoPoint>();
for (Iterator<Placemark> iter=places.iterator();iter.hasNext();) {
Placemark point = (Placemark)iter.next();
points.add(new GeoPoint(p.getLatitude(),p.getLongitude()));
}
//the loop which gives out a null exception
for (int j=0; j <points.size(); j++){
MyOverlay poin = new MyOverlay(points.get(j-1),points.get(j)); }
爲(INT J = 1;Ĵ<點.size(); j ++){ MyOverlay poin = new MyOverlay(points.get(j-1),points.get(j)); } – jay 2012-03-04 00:49:41
