专题图图层

专题图图层，支持矢量图层的点密度专题图、等级符号专题图、统计专题图、标签专题图、分段专题图、单值专题图，栅格图层的分段专题图和单值专题图。专题图的展示可在主线程和监听器类中两种方式来实现。

点密度专题图。专题图效果在主线程中进行展示。

    // 专题图结果
    public ThemeResult result;
    public void ThemeDotDensity() throws InterruptedException, ExecutionException {
        // 定义点密度专题图
        ThemeDotDensity theme = new ThemeDotDensity();
        theme.dotExpression = "Pop_1994";
        theme.value = 5000000;
        ServerStyle dotStyle = new ServerStyle();
        dotStyle.markerSize = 3;
        dotStyle.markerSymbolID = 12;
        theme.style = dotStyle;
        // 定义专题图基数类参数
        ThemeParameters themeParam = new ThemeParameters();
        themeParam.themes = new Theme[] { theme };
        themeParam.dataSourceNames = new String[] { "World" };
        themeParam.datasetNames = new String[] { "Countries" };        
        ThemeService themeservice = new ThemeService("http://MyServerIP:8090/iserver/services/map-world/rest/maps/World");
        MyThemeServiceEventListener listener = new MyThemeServiceEventListener();
        // 和服务端异步通讯
        themeservice.process(themeParam, listener);
        // 等待监听器执行完毕
        try {
            listener.waitUntilProcessed();
        } catch (Exception e) {
            e.printStackTrace();
        }
        // 判断专题图创建是否成功
        if (result == null || result.resourceInfo == null || result.resourceInfo.newResourceID == null) {
            return;
        }
        // 展示已创建的专题图
        LayerView themeLayer = new LayerView(this,"http://MyServerIP:8090/iserver/services/map-world/rest/maps/World");
        themeLayer.setTransparent(true);
        themeLayer.setLayersID(result.resourceInfo.newResourceID);
        // mapview中增加专题图图层
        mapView.addLayer(themeLayer);
    }
    // 监听器类
    class MyThemeServiceEventListener extends ThemeServiceEventListener {
        @Override
        public void onThemeServiceStatusChanged(Object sourceObject, EventStatus status) {
            // 返回结果
