Question

我在我的应用程序中添加了一个OSMDroid地图并且工作正常，但是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

在下面的旧代码中，我在地图上添加了一个“base”-Item，并为地图创建了ItemizedItemOverlay。然后我加载了更多的OverlayItems并将它们添加到列表中，但它们没有出现在地图上。

现在我在AsyncTask完成加载所有项目之后创建ItemizedItemOverlay，现在项目全部可见，OnItemSingleTapUp正在按预期工作，地图上的Double-Tap也适用于那里没有更多的崩溃。我仍然不知道导致崩溃的原因，但它的工作原理如下。

可能的问题：
OverlayItems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个以上的null对象（或null-Refernces？null-Items？正确的术语？） 编辑：没有引起问题，仍然很奇怪。

编辑：我似乎只是在添加更多项目时遇到了崩溃。

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();

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) {
        }
    }

和XML：

 <org.osmdroid.views.MapView xmlns:android="http://schemas.android.com/apk/res/android"
                        android:id="@+id/mapview"
                        android:layout_width="fill_parent"
                        android:layout_height="fill_parent"/>

BIG EDIT：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，它总是会崩溃，但不仅如此。如果我将clickable=true添加到XML，它不再崩溃，但我无法移动地图。

更新如果我不添加更多项目（不要调用AsyncTask），点击项目可以工作并提供预期结果 - 但是如果我添加更多项目，它会在Tap上崩溃。（点击相同的项目，其他项目甚至不可见）

Answer 1

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：

如果您不使用ItemizedIconOverlay，它会崩溃吗？
如果您未向ItemizedIconOverlay添加任何项目，是否会崩溃。
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 - 在onSingleTapUp()中返回false并将该方法中的所有旧代码放在onSingleTapConfirmed中。我刚为Issue 450添加了一张票。
当你点击两次放大时，你说它会崩溃，当你点击一个项目时呢？那会崩溃吗？放大时请确保您没有添加新项目。

因此，ItemizedOverlay通过调用size()来工作，然后为每个项目调用getMarker(index)。出于某种原因，您的ItemizedOverlay认为它只有2个项目。也许你设置了一些断点，特别是addItem()或addItems()和size()。也许这一点，以及上面的答案，将提供一些线索！

Answer 2

您可以尝试覆盖

onSingleTapUp
onSingleTapConfirmed

这对我有用..

@Override
  public boolean onSingleTapUp(MotionEvent event, MapView mapView){

   return true;
  }
@Override
public boolean onSingleTapConfirmed(MotionEvent event, MapView mapView)
{
    return true;

}

Answer 3

您的第二个LogCat只是告诉您slf4j未正确配置。

顺便说一下，您尚未发布完整代码。如果这是你的完整源代码，它将无法通过编译阶段，因为它在语法上不正确。

Answer 4

我想您需要检查谁在修改“MainActivity”。这就是我所能说的。如果您正在使用Eclipse，请密切关注该变量，您可以看到正在发生的事情
