ucmap for android 使用总结

我从业以来，很长有很多时间都在研究gis。不过是开源的还是收费的，多少多会看。现在又看了国内收费的ucmap for android ，说说我的感受吧。目前来说这是我用过接口最奇怪的，怎么说呢。就是跟一般习惯是不一样的。刚开始你会很纳闷，后面我会解释一下。我先声明，只代表个人观点，只是使用者观点。

1，官网

直接百度搜索ucmap即可，打开他们公司官网。下载开发包。

UCMap(V6.6.0)Android.7z：下载开发包，然后是他们公司的官网的论坛，有帖子申请实用码，说是3个月。说起试用码，我就要吐槽了。这个试用码是指定机器的，麻烦。这个码还有问题，我用了不到3个月。demo弹出来的码居然变了，跟我之前申请用的居然不一样了。因为我也做过一些注册码机制类似。这种形式最不好用。说到这里，因为我手机的机器码变了，现在没有码，这篇博客就不贴相关地图的界面，因为会崩溃，也没什么用。

UCMap(V7.0.0)Android.7z：最新版本android的开发包sdk 7.0已经不用试用码（之前的版本都需要）。现在做成跟arcgis 一样，有水印和法律声明。自已下载开发包，里面pdf以及demo，还有接口中文说明都有。这点是比较好的。

这里我就要说一下国内的另外一家超图公司的，那个试用码是3个月，不指定机器。而且是发送到申请邮箱。就是方便。

至于开发包就大家自已去下载吧。

2，加载地图

这是一个官方提供的加载地图的形式。我贴一下主要代码：

        mapView = (MapView) findViewById(R.id.mapView);mapView.setListener(new IMapViewListener() {@Overridepublic void onSizeChanged(int w, int h, int oldw, int oldh) {MapControl mapControl = mapView.getMapControl();mapControl.showScaleBar(8, getResources().getDisplayMetrics().xdpi / 2.54f, 10, mapControl.getHeight() - 10, Color.BLACK, Color.RED, 3, 20);if (mapControl.getMap() == null) {String path = Environment.getExternalStorageDirectory().getPath();if (!new File(path + "/" + workspace + "/map.ini").exists())//这里检查是否具有这个地图，没有则新建App.getInstance().createMap(path + "/" + workspace);mapControl.loadMap(path + "/" + workspace + "/map.ini", (byte) 0);//装载地图mapControl.setPanTool();}}});

这是一个离线地图，看以看出这个是加载根目录下面的bj2文件夹下面的map.ini。如果你测试出现崩溃或者没有地图，那么你自已留意吧。

这个数据是shp数据转换出来的数据库。我们看加载文件就知道。map.ini其实是个配置文件，用记事本打开就知道。有点长，下面我就展示部分。

[Map]
labelColor=0,0,0
LabelStyleCount=0
XMin=116.275146484375
YMin=39.864261627197266
XMax=116.45286494082686
YMax=39.97161865234375
LayerCount=23
[FixedShapefileLayer]0 省界_region 5
MinScale=0.0
MaxScale=0.0
Valid=1
Visible=1
Name=省界_region
Selectable=1
ScaleSymbols=0
[SimpleRenderer]
[FillSymbol]
FillColor_255=153,153,0
OutlineWidth=0.0
OutlineColor_255=153,153,0
然后我们可以在这里找到map.dat 。官方开发包里面都有，不要问我哪里来的数据。bj2文件下面。

用一个可视化sqlite工具打开

这里可以看出每一条数据，都是有一个范围xmin，ymin，xmax，ymax。然后是data，这个就是一系列坐标在里面。大家都知道一个线，面都是由很多坐标组成，那么都在里面了。然后外面是个范围。

研究这个呢？一定要对shp数据文件结构比较了解。这个shp里面东西。相当于把shp数据转换成这个表。

还有还有dbf属性文件转换成一张表的。其实在里面都能找到。

2，加载shp

说起加载shp，应该都是gis当中必备基础功能。上面都看到我解释那个map.ini和map.dat 其实就是shp文件转换出来，有桌面端工具转，也可以用java代码直接转。生成那两个东西。

        mapView = (MapView) findViewById(R.id.mapView);mapView.setListener(new IMapViewListener() {@Overridepublic void onSizeChanged(int w, int h, int oldw, int oldh) {MapControl mapControl = mapView.getMapControl();mapControl.showScaleBar(8, getResources().getDisplayMetrics().xdpi / 2.54f, 10, mapControl.getHeight() - 10, Color.BLACK, Color.RED, 3, 20);if (mapControl.getMap() == null) {String path = Environment.getExternalStorageDirectory().getPath();if (!new File(path + "/shape/map.ini").exists())App.getInstance().createMap(path + "/shape");mapControl.loadMap(path + "/shape/map.ini", (byte) 0);String pathname = path + "/shape/DLTB.shp";ShapefileLayer slayer = ShapefileLayer.createFromSHP((short) mapControl.getMap().getLayerCount(),pathname, 100000, 0, true, true, new SimpleRenderer("", "", new FillSymbol(0xFF00FF00, null)), "GBK");if (slayer != null) {mapControl.getMap().addLayer(slayer);mapControl.getDisplay().getDisplayTransformation().setVisibleBounds(mapControl.getFullExtent());mapControl.rewriteIni();mapControl.refresh();}//经测试，这个没有调用是很卡顿的//将当前的地图工具设置为移动地图工具mapControl.setPanTool();}}});

第一次加载和转一定会卡在哪里，要做进度条的。因为那都是耗时。在动一下程序就无响应了。

其实有耐心的人，都看到了这个两个类基本上是一样的。第一个是直接加载转换好的shp，一个是在android端写代码加载。

那为什么分两个类，都是继承mapview这个类呢。这就是难用地方之一。所有加载地图都是这样写的

        mapView.setListener(new IMapViewListener() {@Overridepublic void onSizeChanged(int w, int h, int oldw, int oldh) {MapControl mapControl = mapView.getMapControl();mapControl.showScaleBar(8, getResources().getDisplayMetrics().xdpi / 2.54f, 10, mapControl.getHeight() - 10, Color.BLACK, Color.RED, 3, 20);if (mapControl.getMap() == null) {mapControl.setPanTool();}}});

这个mapcontrol也是很重要的。自已体会吧。

3，加载谷歌在线地图

这个是demo 1里面功能。

public class MyMapView extends MapView {GPSCustomDraw gpsCustomDraw;public MyMapView(Context context, AttributeSet attrs) {super(context, attrs);}@Overrideprotected void onSizeChanged(int w, int h, int oldw, int oldh) {super.onSizeChanged(w, h, oldw, oldh);if (this.isInEditMode()) return;MapControl mapControl=getMapControl();gpsCustomDraw = new GPSCustomDraw(mapControl);//以下代码会在地图窗口的左下角显示一个比例尺符号，具体参数说明请参考doc//getResources().getDisplayMetrics().xdpi 获取了屏幕的横向dpi，乘以2.54可以得到1厘米有多少个像素点mapControl.showScaleBar(8, getResources().getDisplayMetrics().xdpi/2.54f, 10, mapControl.getHeight()-10, Color.BLACK,Color.RED,3,20);if (mapControl.getMap()==null){String path=Environment.getExternalStorageDirectory().getPath();MapLoader.loadMapXML(mapControl, path+"/OpenSourceMap.xml");//MapLoader.loadMapXML(mapControl,Environment.getExternalStorageDirectory().getPath()+"/cache/OpenSourceMapWithLocal.xml",null,1,0.00001f,true);mapControl.setCustomDraw(gpsCustomDraw);mapControl.setPanTool();((OpenSourceMapLayer)mapControl.getMap().getLayer(0)).openZoomInMode();mapControl.refresh();}}public void close() {if(gpsCustomDraw != null){gpsCustomDraw.close();}}
}

}

自已看怎样放配置文件吧：就是谷歌地址解析的文件。

官方demo 有所说明，怎么放在sd卡存储目录。

还有加载天地图，demo里面没有，暂时不知道怎么实现。

4，demo4 功能

这里面功能主要是对shp转换出来的sql进行编辑了。我写很多注释。

怎么编辑，选中图斑，导出shp，查询属性等等。

5，权限

    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /><uses-permission android:name="android.permission.CHANGE_WIFI_STATE" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /><uses-permission android:name="android.permission.INTERNET" /><uses-permission android:name="android.permission.READ_PHONE_STATE" /><uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /><uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

还有注意你的application一定是这个

 android:name="cn.creable.gridgis.controls.App"

要么你就写一个application继承上面那个。

6，说一下注意事项

如果你的两个界面都是有地图控件，那么销毁界面时候，地图资源记得要释放。不然另外一个地图界面还是一样的数据。

我建议大家下载demo进行运行，然后查看代码，对照接口中文注释，然后看pdf。

大家有没有看过arcgis for android 和超图supmap 的sdk 都是有着版本更新非常大变化。重构幅度很大。

加载shp思路基本都是转换成自已一种格式，进行范围和坐标管理显示。有些是进行R树查询。

其实有个很大难点就是绘制很大的shp文件，怎么做算法查找和显示。

大家对gis这些开发上思路也可以评论一下。
