Android 中使用地图加载wms服务(高德地图，谷歌地图，天地图)

转载请注明出处：http://blog.csdn.net/zkjthinking/article/details/77278838

由于公司需求需要在移动平台上加载自己发布的wms 服务：

高德地图加载wms

谷歌地图加载wms

天地图加载wms或者wmts

目前就做了这几个地图上面加载wms 服务的需求，所有只在这里写这三种；

1.高德地图加载wms：

代码：

//加载自定义wms在你的Activity 中加载 amap为mapview.getAmap();
HeritageScopeTileProvider tileProvider = newHeritageScopeTileProvider();
aMap.addTileOverlay(new TileOverlayOptions().tileProvider(tileProvider));

然后我们看这个自定义类中怎么写吧

public class HeritageScopeTileProvider extends UrlTileProvider {
private String mRootUrl;
//默认瓦片大小
private static int titleSize = 256;//a=6378137±2（m）
//基本参数
private final double initialResolution= 156543.03392804062;//2*Math.PI*6378137/titleSize;
private final double originShift      = 20037508.342789244;//2*Math.PI*6378137/2.0; 周长的一半

private final double HALF_PI = Math.PI / 2.0;
private final double RAD_PER_DEGREE = Math.PI / 180.0;
private final double HALF_RAD_PER_DEGREE = Math.PI / 360.0;
private final double METER_PER_DEGREE = originShift / 180.0;//一度多少米
private final double DEGREE_PER_METER = 180.0 / originShift;//一米多少度

public HeritageScopeTileProvider() {
super(titleSize, titleSize);
//地址写你自己的wms地址
mRootUrl = "http://xxxxxx自己的/wms?LAYERS=cwh:protect_region_38_20160830&FORMAT=image%2Fpng&TRANSPARENT=TRUE&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&SRS=EPSG%3A900913&BBOX=";
}

public HeritageScopeTileProvider(int i, int i1) {
super(i, i1);
}

@Override
public URL getTileUrl(int x, int y, int level) {

try {
String url = mRootUrl + TitleBounds(x, y, level);
return new URL(url);
} catch (MalformedURLException e) {
e.printStackTrace();
}

return null;
}

/**
* 根据像素、等级算出坐标
*
* @param p
* @param zoom
* @return
*/
private double Pixels2Meters(int p, int zoom) {
return p * Resolution(zoom) - originShift;
}

/**
* 根据瓦片的x/y等级返回瓦片范围
*
* @param tx
* @param ty
* @param zoom
* @return
*/
private String TitleBounds(int tx, int ty, int zoom) {
double minX = Pixels2Meters(tx * titleSize, zoom);
double maxY = -Pixels2Meters(ty * titleSize, zoom);
double maxX = Pixels2Meters((tx + 1) * titleSize, zoom);
double minY = -Pixels2Meters((ty + 1) * titleSize, zoom);

//转换成经纬度
minX=Meters2Lon(minX);
minY=Meters2Lat(minY);
maxX=Meters2Lon(maxX);
maxY=Meters2Lat(maxY);
PositionModel position1 = PositionUtil.gcj_To_Gps84(minY,minX);
minX = position1.getWgLon();
minY = position1.getWgLat();
PositionModel position2 = PositionUtil.gcj_To_Gps84(maxY,maxX);
maxX = position2.getWgLon();
maxY = position2.getWgLat();

minX=Lon2Meter(minX);
minY=Lat2Meter(minY);
maxX=Lon2Meter(maxX);
maxY=Lat2Meter(maxY);

return minX + "," + Double.toString(minY) + "," + Double.toString(maxX) + "," + Double.toString(maxY) + "&WIDTH=256&HEIGHT=256";
}
/**
* 计算分辨率
*
* @param zoom
* @return
*/
private double Resolution(int zoom) {
return initialResolution / (Math.pow(2, zoom));
}

/**
* X米转经纬度
*/
private double Meters2Lon(double mx) {
double lon = mx * DEGREE_PER_METER;
return lon;
}
/**
* Y米转经纬度
*/
private double Meters2Lat(double my) {
double lat = my * DEGREE_PER_METER;
lat = 180.0 / Math.PI * (2 * Math.atan(Math.exp(lat * RAD_PER_DEGREE)) - HALF_PI);
return lat;
}
/**
* X经纬度转米
*/
private double Lon2Meter(double lon) {
double mx = lon * METER_PER_DEGREE;
return mx;
}
/**
* Y经纬度转米
*/
private double Lat2Meter(double lat) {
double my = Math.log(Math.tan((90 + lat) * HALF_RAD_PER_DEGREE)) / (RAD_PER_DEGREE);
my = my * METER_PER_DEGREE;
return my;
}

}

看下效果



2.谷歌地图：

谷歌地图要想在Android 中使用，必须要下载谷歌的三驾马车，google play商店, google service, google服务框架，如果需要还要有个google 账号。下载个go 谷歌安装器自动帮你安装；


有了这些东西在手机然后下面的代码跑起来才会起作用：

代码：

//google tilelayer 添加的方式；
GoogleHeritageScopeTileProvider tileProvidergoogle = new GoogleHeritageScopeTileProvider();
mMap.addTileOverlay(new com.google.android.gms.maps.model.TileOverlayOptions().tileProvider(tileProvidergoogle));

看下自定义的代码

public class GoogleHeritageScopeTileProvider extends UrlTileProvider {

private String mRootUrl;
//默认瓦片大小
private static int titleSize = 256;//a=6378137±2（m）
//基本参数
private final double initialResolution= 156543.03392804062;//2*Math.PI*6378137/titleSize;
private final double originShift      = 20037508.342789244;//2*Math.PI*6378137/2.0; 周长的一半

private final double HALF_PI = Math.PI / 2.0;
private final double RAD_PER_DEGREE = Math.PI / 180.0;
private final double HALF_RAD_PER_DEGREE = Math.PI / 360.0;
private final double METER_PER_DEGREE = originShift / 180.0;//一度多少米
private final double DEGREE_PER_METER = 180.0 / originShift;//一米多少度

public GoogleHeritageScopeTileProvider() {
super(titleSize, titleSize);
mRootUrl = "http://xxxxx你自己要加载/wms?LAYERS=cwh:protect_region_38_20160830&FORMAT=image%2Fpng&TRANSPARENT=TRUE&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&SRS=EPSG%3A900913&BBOX=";
}

public GoogleHeritageScopeTileProvider(int i, int i1) {
super(i, i1);
}

@Override
public URL getTileUrl(int x, int y, int level) {

try {
String url = mRootUrl + TitleBounds(x, y, level);
return new URL(url);
} catch (MalformedURLException e) {
e.printStackTrace();
}

return null;
}

/**
* 根据像素、等级算出坐标
*
* @param p
* @param zoom
* @return
*/
private double Pixels2Meters(int p, int zoom) {
return p * Resolution(zoom) - originShift;
}

/**
* 根据瓦片的x/y等级返回瓦片范围
*
* @param tx
* @param ty
* @param zoom
* @return
*/
private String TitleBounds(int tx, int ty, int zoom) {
double minX = Pixels2Meters(tx * titleSize, zoom);
double maxY = -Pixels2Meters(ty * titleSize, zoom);
double maxX = Pixels2Meters((tx + 1) * titleSize, zoom);
double minY = -Pixels2Meters((ty + 1) * titleSize, zoom);

//转换成经纬度
minX=Meters2Lon(minX);
minY=Meters2Lat(minY);
maxX=Meters2Lon(maxX);
maxY=Meters2Lat(maxY);
PositionModel position1 = PositionUtil.gcj_To_Gps84(minY,minX);
minX = position1.getWgLon();
minY = position1.getWgLat();
PositionModel position2 = PositionUtil.gcj_To_Gps84(maxY,maxX);
maxX = position2.getWgLon();
maxY = position2.getWgLat();

minX=Lon2Meter(minX);
minY=Lat2Meter(minY);
maxX=Lon2Meter(maxX);
maxY=Lat2Meter(maxY);

return minX + "," + Double.toString(minY) + "," + Double.toString(maxX) + "," + Double.toString(maxY) + "&WIDTH=256&HEIGHT=256";
}

/**
* 计算分辨率
*
* @param zoom
* @return
*/
private double Resolution(int zoom) {
return initialResolution / (Math.pow(2, zoom));
}

/**
* X米转经纬度
*/
private double Meters2Lon(double mx) {
double lon = mx * DEGREE_PER_METER;
return lon;
}

/**
* Y米转经纬度
*/
private double Meters2Lat(double my) {
double lat = my * DEGREE_PER_METER;
lat = 180.0 / Math.PI * (2 * Math.atan(Math.exp(lat * RAD_PER_DEGREE)) - HALF_PI);
return lat;
}

/**
* X经纬度转米
*/
private double Lon2Meter(double lon) {
double mx = lon * METER_PER_DEGREE;
return mx;
}

/**
* Y经纬度转米
*/
private double Lat2Meter(double lat) {
double my = Math.log(Math.tan((90 + lat) * HALF_RAD_PER_DEGREE)) / (RAD_PER_DEGREE);
my = my * METER_PER_DEGREE;
return my;
}

}

效果



3.天地图加载wms或者wmts；

//必须符合人家这个发布的规定，不符合加不上去的
String url = "http://t7.tianditu.com/DataServerT=vec_c&x=13394&y=2704&l=14";
mTianDiTuMap.setCustomTileService(url);

看下源码吧







好了，可以看到加载的话，只能符合人家的规范。若不是，好像并没有好的解决方案。

总结： 从高德地图和谷歌地图添加wms,这里是不是有一些惊奇的发现了，这个添加的方式基本相同（甚至类名和方法名都相同），知道一种另一个也就会添加了。还有些更多的可以自己看看人家源码；当然高德和Google在国内都是使用GCJ－02坐标系。就是我们常说的“火星坐标系”，至于天地图这个加载wms和wmts 的方式必须符合人家的发布规定。我并没有找到可靠的在高德和谷歌地图加载wmts 的方法，如果我如果那位大牛知道。麻烦告诉我感激不尽。
