在android上使用自定义地图arcGIS

Question

我正在使用arcGIS android API来创建我所在大学的基于android的地图应用程序。我遇到的问题是我不知道如何使用shapefile中的图层加载自定义地图，因此我无法使用该应用程序。如果有人能告诉我如何欣赏它。

使用ShapefileFeatureTable和FeatureLayer。按照https://github.com/Esri/arcgis-runtime-demos-android/blob/master/2015-DS/DevSummitDemo/DevSummitDemo/src/main/java/com/esri/android/devsummit/DevSummitDemoActivity.java上的示例：

try {
        mTable = new ShapefileFeatureTable(filePath + fileExt);

        mFlayer = new FeatureLayer(mTable);


        // Set renderer based on geometry type

        if (mTable.hasGeometry()) {

          if (mTable.getGeometryType() == Geometry.Type.POLYLINE) {

            mFlayer.setRenderer(new SimpleRenderer(new SimpleLineSymbol(Color.YELLOW, 0.50f)));

          } else if (mTable.getGeometryType() == Geometry.Type.POLYGON) {

            mFlayer.setRenderer(new SimpleRenderer(new SimpleFillSymbol(getResources().getColor(R.color.accent))));

          } else if (mTable.getGeometryType() == Geometry.Type.POINT) {

            mFlayer.setRenderer(new SimpleRenderer(new SimpleMarkerSymbol(Color.YELLOW, 1, STYLE.CIRCLE)));

          }

        }


        mMap.addLayer(mFlayer);

      } catch (FileNotFoundException e) {

        // TODO Auto-generated catch block

        e.printStackTrace();

      } catch (Exception e1) {

        Toast.makeText(getApplicationContext(), "Adding Shapefile has failed, please restart app to add shapefiles.", Toast.LENGTH_SHORT).show();

        e1.printStackTrace();

      }
