 ArcGIS for Android示例解析之高亮要素-----HighlightFeatureshttp://blog.csdn.net/wozaifeiyang0/article/details/7323606

arcgis android 中 Geodatabase geodata = new Geodatabase(filepath);得到geodata为空http://zhidao.baidu.com/link?url=iH5IDhbjIKOrZE3WffmhHwJ2ZqFF8AzU8tir8qvSl_BP5AUIHiGSc3aKbqZ7MWVHS1_8Umey4tgNcm9fEm3eVX0pN5DMnhe2_Z7FoGa2ppe&qq-pf-to=pcqq.group

ArcGIS for Android示例解析之FeatureLayer服务-----SelectFeatureshttp://bbs.hiapk.com/thread-3940420-1-1.html

过程：

通过FeatureLayer我们可以很快的查询出所选的要素，并进行渲染。下面我们梳理一下选择查询的步骤：

1、              FeatureLayer图层对象所需的参数的设置，如：自身的url设置，Options对象设置，以及选择的要素渲染的样式设置等。
2、              定义一个Query对象，并且给其设置所需的值，如：设置查询条件、是否返回几何对象、输入的空间参考、空间要素以及查询的空间关系。
3、              执行FeatureLayer对象的selectFeatures（）方法。

 4 、Graphic graphic = new Graphic(feature.getGeometry(),
                               sfs);
                        // add graphic to layer
                        mGraphicsLayer.addGraphic(graphic);

详细：先

1.GraphicsLayer mGraphicsLayer = new GraphicsLayer();  //类似于画布

final String tpkPath = "/Arcgis/hello.tpk";
    public static final String GEO_FILENAME="/Arcgis/hello/data/z01.geodatabase";//数据存放地址

2. onCreate里面加 mMapView.addLayer(mGraphicsLayer); 

3.class TouchListener extends MapOnTouchListener ｛

长按清除所有画布的要素

public void onLongPress(MotionEvent point) {      // Our long press will clear the screen      mStops.clearFeatures();      mGraphicsLayer.removeAll();      mMapView.getCallout().hide();    }

public boolean onSingleTap(MotionEvent point) {        Point mapPoint = mMapView.toMapPoint(point.getX(), point.getY());        Log.i("zjx",""+mapPoint.getX()/1000+",,,"+(mapPoint.getY()/1000+1));        Graphic graphic = new Graphic(mapPoint, new SimpleMarkerSymbol(Color.BLUE, 10, STYLE.DIAMOND));        mGraphicsLayer.addGraphic(graphic);｝

单击得到相对地图的位置

双击。。这里我订死了查询条件，显示要素

Geodatabase geodatabase =null;
        try {
            geodatabase =new Geodatabase(filename);
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        List<GeodatabaseFeatureTable> table = geodatabase
      .getGeodatabaseTables();
        Log.i("zjx","list:"+table);
        GeodatabaseFeatureTable mytable=geodatabase.getGeodatabaseFeatureTableByLayerId(0);

得到数据库 以及第一个数据表
