如果您从 SD 卡加载数据，您可以使用 openmap，它有一个 SShapefile 类，并尝试将您的 shapefile 转换为图形层，它会起作用我已经完成了。

static public GraphicsLayer SHPtoPOINT(String shpfile) {
    SpatialReference lSR = SpatialReference.create(26192);
    Envelope lEnvolope = getSHPEnvelope(shpfile);//to create an extent for your graphics       layer
    GraphicsLayer graphicLayer = new GraphicsLayer(lSR, lEnvolope);

    try {
        File file = new File(shpfile);
        ShapeFile shp = new ShapeFile(file);
        ESRIPointRecord e = (ESRIPointRecord) shp.getNextRecord();
        SimpleMarkerSymbol c_point = new SimpleMarkerSymbol(Color.BLACK, 1,
        STYLE.CIRCLE);
            while (e != null) {
            graphicLayer.addGraphic(new Graphic(new Point(e.getX(), e.getY()), c_point));
            e = (ESRIPointRecord) shp.getNextRecord();
            }
       shp.close();
       } catch (IOException e1) {
       e1.printStackTrace();
       }
      return graphicLayer;
    }
