Android 在google地图上创建标记时出现非法状态异常
嗨,我正试图在谷歌地图v2上显示一些标记点。在我找到这个bug之前一切都很好。出于某种原因,如果我加载带有2个指针的地图,然后关闭并重新加载,我会收到以下消息: “IllegalStateException无包含点” 调用时出现此错误:Android 在google地图上创建标记时出现非法状态异常,android,google-maps,illegalstateexception,Android,Google Maps,Illegalstateexception,嗨,我正试图在谷歌地图v2上显示一些标记点。在我找到这个bug之前一切都很好。出于某种原因,如果我加载带有2个指针的地图,然后关闭并重新加载,我会收到以下消息: “IllegalStateException无包含点” 调用时出现此错误: LatLngBounds bounds = builder.build(); 这是我在地图上标出的点: // Point the map's listeners at the listeners implemented by the cluster

CameraUpdate cu = CameraUpdateFactory.newLatLngBounds(bounds, padding);
googleMap.moveCamera(cu);
googleMap.setOnCameraChangeListener(mClusterManager);
}catch (Exception e)

});
有人能帮忙吗

在UI线程上运行标记任务
runOnUiThread(new Runnable() {
@Override
public void run() {
//Add your marker here...
}
});
在API中,我们发现: 公共LatLngBounds(LatLng西南、LatLng东北):如果东北角的纬度低于西南角的纬度,则为非法辩论例外 在代码中,当计算边界的列表为空时,将启动异常:
LatLngBounds.Builder builder = LatLngBounds.builder();
for(ModelLatLngDisplay p: yourList)
{
builder = builder.include(p.latLng);
}
return builder.build();
我想你的问题就在这里
for (Ad ad : Constants._results)
{
builder.include(new LatLng(ad.getLat(), ad.getLon()));
}
常量。\u结果必须为空,因此生成器中没有LatLng点。调试和检查
