场景图

SDK提供已封装业务的接口来切换视图，可以切换2D车首上、3D车首上、2D北首上三个模式。也可以直接设置修改地图俯仰角，旋转角参数来改变地图视角。

1）首次进入主图默认视角为 2D车首上；

2）点击视角按钮切换视图；

2D车首上

上部：“北”icon始终指向地理正北方向，点击按钮进行视角切换，切换至3D车首上

地图姿态：地图俯仰角为0°，地图旋转角跟车标角度一致；

3D车首上

上部：“北”icon始终指向地理正北方向，点击按钮进行视角切换，切换至2D北首上；

地图姿态：地图俯仰角为65°，地图旋转角跟车标角度一致；

$\"image.png\"$

2D北首上：

上部：始终显示红色指针，指向图面正上方，点击按钮进行视角切换，切换至2D车首上；

地图姿态：地图俯仰角为0，地图旋转角为0；

核心接口

设置地图模式

void com.autonavi.gbl.map.MapView.setMapMode(MapviewModeParam ModeParam, boolean bAnimation)

说明：函数详情，请复制函数名称到在线API搜索

调用示例

设置地图模式

//创建mapview实例\n...\n\n//2D北上\nMapviewModeParam mapviewModeParam = new MapviewModeParam();\nmapviewModeParam.bChangeCenter = true;\nmapviewModeParam.mode = MapviewMode.MapviewModeNorth;\nmapviewModeParam.mapZoomLevel = mapView.getOperatorPosture().getZoomLevel();\nmapView.setMapMode(mapviewModeParam, true);\nmapView.resetTickCount(1);\n\n//2D车上\nMapviewModeParam mapviewModeParam = new MapviewModeParam();\nmapviewModeParam.bChangeCenter = true;\nmapviewModeParam.mode = MapviewMode.MapviewModeCar;\nmapviewModeParam.mapZoomLevel = mapView.getOperatorPosture().getZoomLevel();\nMapView.setMapMode(mapviewModeParam, true);\nmapView.resetTickCount(1);\n\n//3D车上\nMapviewModeParam mapviewModeParam = new MapviewModeParam();\nmapviewModeParam.bChangeCenter = true;\nmapviewModeParam.mode = MapviewMode.MapviewMode3D;\nmapviewModeParam.mapZoomLevel = mapView.getOperatorPosture().getZoomLevel();\nmapView.setMapMode(mapviewModeParam, true);\nmapView.resetTickCount(1);
