基于SuperMap的iMobile 3D总结（三）

1、popupWindow

popupWindow = new PopupWindow(view, 611, 603);
tvUserName.setText(userName);
// 使其聚集
popupWindow.setFocusable(true);
// 设置允许在外点击消失
popupWindow.setOutsideTouchable(true);
popupWindow.setBackgroundDrawable(new BitmapDrawable());
WindowManager windowManager = (WindowManager) getActivity().getSystemService(Context.WINDOW_SERVICE);
// 显示的位置为:屏幕的宽度的一半-PopupWindow的高度的一半
int xPos = windowManager.getDefaultDisplay().getWidth() / 2- popupWindow.getWidth() / 2;
int yPos = windowManager.getDefaultDisplay().getHeight() / 2 - popupWindow.getHeight() / 2 - 200;
Log.i("coder", "xPos:" + xPos);
popupWindow.showAsDropDown(convertView, xPos, yPos);

2、Geometry查询

  private void queryPointbyGeometry(Point2D point2D, String dataSource, String dataSet) {com.supermap.services.components.commontypes.Geometry geometry = new com.supermap.services.components.commontypes.Geometry();com.supermap.services.components.commontypes.Point2D[] points = new com.supermap.services.components.commontypes.Point2D[]{new com.supermap.services.components.commontypes.Point2D(point2D.getX(), point2D.getY())};geometry.points = points;geometry.type = GeometryType.POINT;GetFeaturesResult result = excute_geometryQuery(Constant.QUERY_B13, geometry);if (result != null && result.featureCount > 0) {Feature[] features = result.features;String[] fieldValues = features[0].fieldValues;int id = Integer.parseInt(fieldValues[0]);int[] selectIds = new int[]{id};Layer3Ds layers = sceneControl.getScene().getLayers();for (int i = 0; i < layers.getCount(); i++) {if (layers.get(i).getName().equalsIgnoreCase("b13@udb13")) {Layer3D layer3D = layers.get(i);b13dosgFile = (Layer3DOSGBFile) layer3D;}}b13dosgFile.clearObjectsColor();b13dosgFile.setObjectsColor(selectIds, new Color(255, 0, 0));feature = features[0];handler.sendEmptyMessage(1000);} else {handler.sendEmptyMessage(1001);}}

3、点击item，scene里面高亮对应图形

  Feature feature = featureList.get(position);Geometry geometry = feature.geometry;Point2D[] points = geometry.points;
//                Log.e("msg", geometry.getCenter().x + "-" + geometry.getCenter().y + "-------");sceneControl.getScene().fly(new LookAt(points[0].x, points[0].y, 120), 1000, true);int[] ids = new int[]{feature.getID()};Layer3Ds layers = sceneControl.getScene().getLayers();for (int i = 0; i < layers.getCount(); i++) {if (layers.get(i).getName().equalsIgnoreCase("b13@udb13")) {Layer3D layer3D = layers.get(i);Layer3DOSGBFile layer3dosgbfile = (Layer3DOSGBFile) layer3D;layer3dosgbfile.clearObjectsColor();
//                        layer3dosgbfile.removeObjectsColor(selectIds);layer3dosgbfile.setObjectsColor(ids, new Color(255, 0, 0));}}

4、获取iServer里面的需要的字段

 public static final String FIELD_B13 = "http://192.168.5.229:8090/iserver/services/data-b13Mobile/rest/data/datasources/udb13/datasets/b13_polygon/fields.json"; /*** init field values*/private void initQueryFields() {OkHttpClient client = new OkHttpClient();Request build = new Request.Builder().url(Constant.FIELD_B13).get().build();Call call = client.newCall(build);call.enqueue(new Callback() {@Overridepublic void onFailure(Call call, IOException e) {Log.e("msg", e.getMessage());}@Overridepublic void onResponse(Call call, Response response) throws IOException {if (response != null) {String string = response.body().string();Log.e("msg", string + "");try {JSONObject jsonObject = new JSONObject(string);JSONArray fieldNames = jsonObject.getJSONArray("fieldNames");queryFields = new String[fieldNames.length()];for (int i = 0; i < fieldNames.length(); i++) {Object o = fieldNames.get(i);Log.e("msg", o.toString() + "");queryFields[i] = o.toString();}handler.sendEmptyMessage(100);} catch (JSONException e) {e.printStackTrace();}}}});}

5、属性查询、渲染图层

    //b13的查询路径
public static final String QUERY_B13 = "http://192.168.5.229:8090/iserver/services/data-b13Mobile/rest/data";Layer3Ds layers = sceneControl.getScene().getLayers();for (int i = 0; i < layers.getCount(); i++) {if (layers.get(i).getName().equalsIgnoreCase("b13@udb13")) {Layer3D layer3D = layers.get(i);b13dosgFile = (Layer3DOSGBFile) layer3D;}}clearMapColor();queryPointbySQL("udb13", "b13_polygon", sql, Constant.QUERY_B13);

 /*** clear b13area model color*/private void clearMapColor() {b13dosgFile.clearObjectsColor();}/*** query b13 data url by sql*/private void queryPointbySQL(String dataSource, String dataSet, String sql, String url) {String[] dtnames = {dataSource + ":" + dataSet};QueryParameter parameter = new QueryParameter();parameter.attributeFilter = sql;GetFeaturesBySQLParameters sqlParameters = new GetFeaturesBySQLParameters();sqlParameters.datasetNames = dtnames;sqlParameters.queryParameter = parameter;GetFeaturesBySQLService sqlService = new GetFeaturesBySQLService(url);MyEventListener eventListener = new MyEventListener();sqlService.process(sqlParameters, eventListener);}/*** 要素请求服务监听*/class MyEventListener extends GetFeaturesByGeometryService.GetFeaturesEventListener {@Overridepublic void onGetFeaturesStatusChanged(Object o, EventStatus eventStatus) {if (EventStatus.PROCESS_COMPLETE.getValue() == eventStatus.getValue() && o != null) {featuresResult = (GetFeaturesResult) o;Feature[] featuresarr = featuresResult.features;for (int i = 0; i < featuresarr.length; i++) {featureList.add(featuresarr[i]);}/*for (int i = 0; i < features.length; i++) {String[] fieldNames = features[i].fieldNames;String[] fieldValues = features[i].fieldValues;}*/Log.i("查询:", "成功");handler.sendEmptyMessage(101);/*  queryAdapter = new Query2Adapter(getActivity(), feature);rcvQuery.setAdapter(queryAdapter);*/}}}
