通过ShapfileFeatureTable加载本地shapfile数据

###文件位置

已将shp数据（.dbf、.sbn、.sbx、.shp、.shx）存入移动端

问题描述

在实例化ShapefileFeatureTable对象时，显示为null

###调用方法

public void LoadShapFile(String shpPath, ArcGISMap mArcGISMap) {
// 构建ShapefileFeatureTable，引入本地存储的shapefile文件
ShapefileFeatureTable shapefileFeatureTable = new ShapefileFeatureTable(shpPath);
shapefileFeatureTable.loadAsync();
// 构建featureLayerr
mFeatureLayer = new FeatureLayer(shapefileFeatureTable);
// 设置Shapefile文件的渲染方式
SimpleLineSymbol lineSymbol = new SimpleLineSymbol(SimpleLineSymbol.Style.SOLID, Color.RED, 1.0f);
SimpleFillSymbol fillSymbol = new SimpleFillSymbol(SimpleFillSymbol.Style.SOLID, Color.YELLOW, lineSymbol);
SimpleRenderer renderer = new SimpleRenderer(fillSymbol);
mFeatureLayer.setRenderer(renderer);
//设置选中颜色
mFeatureLayer.setSelectionWidth(5);
mFeatureLayer.setSelectionColor(Color.GREEN);
//mMapView.setViewpointGeometryAsync(mFeatureLayer.getFullExtent());
// 添加到地图的业务图层组中
mArcGISMap.getOperationalLayers().add(mFeatureLayer);
}
