java如何在地图视图上添加超过100个标记

1 周，5 日 Questions & Answers 532

我在开发者网站上学习了Hello MapView教程，一切都很顺利。但现在我需要扩展它来添加大约150个标记，我当前的方法会使我的应用程序崩溃

Reason: keyDispatchingTimedOut

我的设置如下

包含地图数据的四个字符串数组，都具有（并且将始终具有）完全相同数量的索引和fId[0]==平坦度[0]==浮动度[0]==FD细节[0]，依此类推：

    String[] fId;
    String[] fLatitude;
    String[] fLongitude;
    String[] fDetails;

到目前为止，这就是我在地图上绘制点的方式。这显然不是正确的方法，因为地图不断崩溃：

        List<Overlay> mapOverlays = mapView.getOverlays();
    Drawable drawable = this.getResources().getDrawable(R.drawable.安卓marker);
    FriendItemizedOverlay itemizedoverlay = new FriendItemizedOverlay(drawable, mapView.getContext());

    for(int i=0;i<aLatitude.length;i++){

        Double intLon = Double.parseDouble(aLongitude[i]);
        Double intLat = Double.parseDouble(aLatitude[i]);

        GeoPoint point = new GeoPoint((int)(intLat * 1E6), 
                (int)(intLon * 1E6));
        OverlayItem overlayitem = new OverlayItem(point, "Friend ", "Something");

        itemizedoverlay.addOverlay(overlayitem);
        mapOverlays.add(itemizedoverlay);

    }

如果您需要更多信息，请在评论中告诉我，谢谢

有 Java 编程相关的问题?
