缩小时OSMDroid崩溃
作者：互联网
我已经在我的应用程序中添加了OSMDroid地图,它工作正常,但是如果我缩小地图,它会崩溃.
我在将地图加载到用户当前位置时添加了一个项目,并在加载地图后在AsyncTask中加载了另外10个项目.
更新：工作解决方案
在下面的旧代码中,我在用户位置的地图上添加了一个“基本”项,并为地图创建了ItemizedItemOverlay.然后,我加载了更多OverlayItems并将其添加到列表中,但是它们没有出现在地图上.
现在,我在AsyncTask完成所有项目的加载之后创建ItemizedItemOverlay,现在所有项目都可见,OnItemSingleTapUp可以按预期工作,在地图上双击也可以正常工作,并且不再崩溃.我仍然不太清楚是什么原因导致了崩溃,但是它的工作原理是这样的.
可能的问题：
OverlayItems列表用零个对象初始化(显然),但是我添加了一个OverlayItem之后,它包含1个OverlayItem,又包含11个null对象(或null-Refernces？null-Items？正确的术语是什么？)
编辑：没有引起问题,仍然很奇怪.
编辑：看来我只会在添加更多项目时崩溃.
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”了地图：
@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"/>
大编辑：我的大多数问题现在已解决,但仍然崩溃.
当我双击地图时,它总是崩溃,但不仅如此.
如果我将clickable = true添加到XML,它不再崩溃,但是我无法移动地图.

更新：
如果我不添加更多项目(不调用AsyncTask),则点击该项目即可正常工作并提供预期的结果-但是,如果我添加更多项目,则在Tap上崩溃. (在同一项目的Tap上,其他的甚至都不可见)
解决方法:
在上一次编辑中,您发布了完整的stacktrace-谢谢,这就是我们所需要的.我会忽略“下载瓷砖时出错”,因为那不是崩溃您的应用程序的原因.崩溃发生在“ IndexOutOfBoundsException”中.您的问题开始因过多的信息而变得一发不可收拾-我们将其简化并找出问题所在.当崩溃发生时您在做什么-您在问题中说双击时会发生崩溃,但该异常与ItemizedIconOverlay和onSingleTapUp有关.可以尝试的一些事情：
>如果不使用ItemizedIconOverlay,是否会崩溃？
>如果您不向ItemizedIconOverlay添加任何项目,是否会崩溃？
>查看ItemizedItemOverlay,如果将onSingleTapUp()中的所有代码移至onSingleTapConfirmed()会怎样.那才是真正的归属.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入onSingleTapConfirmed中.我刚刚添加了一张Issue 450的门票.
>您说双击以放大时会崩溃,当您点击一个项目时会怎么样？那会崩溃吗？确保放大时没有添加新项目.
因此,ItemizedOverlay通过调用size()进行工作,然后为每个项目调用getMarker(index).由于某种原因,您的ItemizedOverlay认为只有2个项目时才有2个项目.也许您设置了一些断点,尤其是在addItem()或addItems()和size()中.也许,与上述答案一起,将提供一些线索！
