加载geodatabase数据
private FeatureLayer valueFL; //离线数据图 @Override public void getLocalMapServerDiFangData(){ try { List list=null; if (Environment.MEDIA_MOUNTED.equals(Environment.getExternalStorageState())){ File file=Environment.getExternalStorageDirectory().getAbsoluteFile(); File file1=new File(file,Constant.LOCAL_DATA); if (file1.exists()){ list=Arrays.asList(file1.listFiles(new FilenameFilter() { @Override public boolean accept(File dir, String name) { return name.endsWith("geodatabase"); } })); } } if (list==null||list.size()==0){ messageDialog("请在手机SD卡根目录下localdata文件架下放入geodatabase文件!"); }else { String mainGeodatabaseFilePath =list.get(0).getPath(); final Geodatabase mainGeodatabase = new Geodatabase(mainGeodatabaseFilePath); mainGeodatabase.loadAsync(); mainGeodatabase.addDoneLoadingListener(new Runnable() { @Override public void run() { List resultsGFT = mainGeodatabase.getGeodatabaseFeatureTables(); valueFL = new FeatureLayer(resultsGFT.get(2)); QueryParameters query = new QueryParameters(); query.setWhereClause("1=1");// 设置空间几何对象 FeatureTable mTable = valueFL.getFeatureTable();//得到查询属性表 final ListenableFuture featureQueryResult = mTable.queryFeaturesAsync(query); featureQueryResult.addDoneListener(new Runnable() { @Override public void run() { try { FeatureQueryResult featureResul = featureQueryResult.get(); mGeometryMap = new HashMap(); for (Object element : featureResul) { if (element instanceof Feature) { Feature mFeatureGrafic = (Feature) element; Map mQuerryString = mFeatureGrafic.getAttributes(); mList.add(mQuerryString); mGeometryMap.put(mQuerryString.get("TBYBH") + "", mFeatureGrafic.getGeometry()); mLayerMap.put(mQuerryString.get("TBYBH") + "_"+mQuerryString.get("YH")+"_"+mQuerryString.get("DCLY"),mFeatureGrafic); } } getSortData(mList); Message message = new Message(); message.what = 666; mHandler.sendMessage(message); }catch (Exception e){ e.printStackTrace(); } } }); valueFL.setVisible(true); LayerList mainLayerList = mArcGISMap.getOperationalLayers(); mainLayerList.add(valueFL); } }); } } catch (Exception e) { } } 离线切片tpk:
