缩小时OSMDroid崩溃

Ben*_*alb 2 android osmdroid

我在我的应用程序中添加了一个OSMDroid地图,它工作正常,但如果我缩小,它会崩溃.

我在用户当前位置加载Map时添加一个Item,并在加载地图后在AsyncTask中再加载10个.

更新:工作解决方案

在我下面的旧代码中,我在用户位置向地图添加了一个"base"-Item,并ItemizedItemOverlay为地图创建了一个.然后我加载了更多OverlayItems并将它们添加到列表中,但它们没有出现在地图上.

现在我创建了ItemizedItemOverlayAsyncTask完成加载所有项目之后,现在项目全部可见,OnItemSingleTapUp按预期工作,地图上的Double-Tap也可以,并且不再有崩溃.我仍然不知道是什么导致了崩溃,但它的工作原理是这样的.

可能的问题:
OverlayItems的列表初始化为零对象(显然),但在我添加一个OverlayItem之后,它包含1个OverlayItem + 11个更多的null-对象(或null-Refernces？null-Items？正确的术语是什么？ ) 编辑: didnt引起的问题,还是陌生的.

编辑:似乎我只是在添加更多项目时遇到崩溃.

这是我的完整代码和Logcat:

mResourceProxy = new DefaultResourceProxyImpl(getApplicationContext());

mapView.setTileSource(TileSourceFactory.MAPNIK);
mapView.setBuiltInZoomControls(true);
mapView.setMultiTouchControls(true);
mapController = this.mapView.getController();
mapController.setZoom(25);
GeoPoint center = new GeoPoint(DataManager.glat, DataManager.glon);
mapController.setCenter(center);
mLocMgr = (LocationManager) getSystemService(LOCATION_SERVICE);

mLocMgr.requestLocationUpdates(LocationManager.GPS_PROVIDER, 1000, 100,
        this);

items = new ArrayList<OverlayItem>(); // items now null
items.add(new OverlayItem("Here", "SampleDescription", center));
// items now contains 1 OverlayItem and 11 null-items

this.mLocationOverlay = new ItemizedIconOverlay<OverlayItem>(items,
new ItemizedIconOverlay.OnItemGestureListener<OverlayItem>() {
            @Override
            public boolean onItemSingleTapUp(final int index,
                    final OverlayItem item) {

                Intent intent=new Intent();
                intent.putExtra("newShopName", item.mTitle);
                intent.putExtra("newShopAdd", item.mDescription);
                setResult(RESULT_OK, intent);
                finish(); 

                return true; 
            }
            @Override
            public boolean onItemLongPress(final int index,
                    final OverlayItem item) {

                toast = Toast.makeText(ShopChooseActivity.this, item.mTitle + ", " + item.mDescription, Toast.LENGTH_LONG);
                toast.show();
                return false;
            }
        }, mResourceProxy);

this.mapView.getOverlays().add(this.mLocationOverlay);
mapView.invalidate();

在这里我称之为AsyncTask:

loadMap = new LoadChooseShop(ShopChooseActivity.this, items).execute();

在这里我"刷新"地图:

@Override
    public void onTaskCompleted(int returncode) {
        try {
            items = loadMap.get();

            if(items != null)
            mapView.invalidate();
            else {
                Toast.makeText(getApplicationContext(), R.string.error_connectionfailure , Toast.LENGTH_LONG).show();
                setResult(RESULT_CANCELED);
                finish();
            }
        } catch (InterruptedException e) {
        } catch (ExecutionException e) {
        }

大编辑:我的大多数问题现在都已解决,但仍然崩溃.

当我双击地图时它总是崩溃,但不仅如此.如果我添加clickable=true到XML,它不再崩溃,但我无法移动地图.

更新: 如果我没有添加更多项目(不要调用AsyncTask),点击项目工作并提供预期结果 - 但如果我添加更多项目,它会在Tap上崩溃.(点击相同的项目,其他甚至不可见)

kur*_*arc 5

在上一次编辑中,您发布了完整的堆栈跟踪 - 谢谢,这就是我们需要的.我会忽略"错误下载磁贴",因为这不是崩溃你的应用程序.崩溃发生在"IndexOutOfBoundsException"中.你的问题开始逐渐失控,信息太多 - 让我们简化它并隔离问题.崩溃发生时你在做什么 - 你在问题中说你双击时会发生这种情况,但异常与ItemizedIconOverlay和onSingleTapUp有关.有些事要尝试:

  1. 如果不使用ItemizedIconOverlay,它会崩溃吗？
  2. 如果您不向ItemizedIconOverlay添加任何项目,它会崩溃吗？
  3. 查看ItemizedItemOverlay,如果将onSingleTapUp()中的所有代码移动到onSingleTapConfirmed(),该怎么办？这就是它所属的地方.如果您不想从源代码重建osmdroid,那么您应该能够扩展ItemizedIconOverlay并覆盖这两种方法 - 返回false onSingleTapUp()并将该方法中的所有旧代码放入其中onSingleTapConfirmed.我刚刚为问题450添加了一张票.
  4. 你说双击放大时会崩溃,当你点击一个项目时怎么样？那会崩溃吗？放大时确保不添加新项目.

因此,ItemizedOverlay通过调用工作size(),然后调用getMarker(index)每个项目.出于某种原因,您的ItemizedOverlay认为它只有2个项目.也许如果你设置一些断点,特别是在addItem()和addItems()和size().也许这一点,以及上面的答案,将提供一些线索!
