imobile如何重新导入shp
ranmj093...
82EXP 2022年07月29日
各位大佬，我需要在矢量图层加载后，在某一时刻重新替换原始shp文件，请问，如何将已加载的数据集和图层删除后重新导入shp文件并加载至图层中？目前，我在DataConversion.importSHP之前判断工作空间是否有数据集和图层存在，如果有就将对应的数据集和图层删掉后导入，导入是在一个线程中导入shp并添加到图层，但是程序一直崩溃，崩溃日志如下：

问题关闭原因： 解决

1个回答

您好，1.请问您的意思是删除数据集就会引起上述崩溃是吗，

2.“但是这种在获取图斑属性时，有可能得不到最新的数据”指的是“得不到最新的信息”这种情况不是必现的吗

3.请问您有没有尝试过只移除数据集呢，如果有的话，在移除数据集的时候有没有关闭数据集再移除呢，还是数据集在没有打开的情况下移除出现了上述的崩溃问题呢

针对第1点和第三点，测试发现删除数据集会造成崩溃，且关闭数据集后再移除同样会出现崩溃。针对第二点，如果不删除数据集，重新导入得不到最新的是必现的啊，所以才问如何重新导的嘛，另外你说的有可能是因为我没关闭数据集造成的崩溃，个人觉得这个有点不太合理吧？如果没有关闭数据集就删除数据集也不应该会导致程序崩溃。另外附上删除数据集和删除图层的代码：

newlayers.forEach {
    val existDataset = mapActivity.udbDatasource!!.datasets.get(it.datasetName)
    if (existDataset != null) {
        if(existDataset.isOpen){
            existDataset.close()
        }

        mapActivity.udbDatasource!!.datasets.delete(it.datasetName)
        var layer = mMap!!.layers.getByCaption("${it.datasetName}@Layer")
        if (layer != null) {
            mMap!!.layers.remove(layer)
        }

        var l1 = mMap!!.layers.getByCaption("${it.datasetName}@themLabelLayer")
        if (l1 != null) {
            mMap!!.layers.remove(l1)
        }
    }
}

就不管关不关数据集，删除数据集都会崩

您好，我这边测试删除没问题的，不会崩溃，删除也可用成功，您可以看下我的代码，这里先移除图层再关闭数据集最后删除数据集

private void delete(){
   Datasets datasets = mWorkspace.getDatasources().get(0).getDatasets();
   for (int i = 0; i < datasets.getCount(); i++) {
      String name = datasets.get(i).getName();
       if (name.equals("shpImport")){
         Dataset dataset = datasets.get(i);
         mMapControl.getMap().getLayers().remove(dataset.getName()+"@World");
         dataset.close();
         datasets.delete(name);
         mMapControl.getMap().refresh();
      }
   }
}

希望可用帮助到您。

看了下代码，然后将逻辑改成先删图层再删数据集后，发现还是会崩，然后检查下代码和崩溃信息在重新导入shp结束后使用 mMap!!.refresh()时，也会导致程序崩溃。也不知道是啥原因，但是根据你提供的思路，崩溃没那么频繁了，算是解决了吧，另外，附上经常遇到的崩溃信息：

另外说句不知道该不该说的，之前有做过arcgis的开发，觉得用imobile经常会遇到崩溃，而且不太好排查，有可能是因为代码逻辑原因哈。
