1、加载本地shp

导出的shp必须是utf-8编码的，否则shp中的中文字段会乱码

private FeatureLayer featureLayer;
private MapView mMapView;    

public void loadShp() {
        // shp文件存在本地的路径
        String shpPath = Environment.getExternalStorageDirectory()
                .toString() + "/11.shp";
        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);
        //fillSymbol为填充样式
        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);
