OSMDroid支持当前基本的地图操作

一般地图的基本操作就是

 

·初始化地图

·按键放大缩小地图

·双指放大缩小地图

·双指旋转地图

·初始化地图放缩等级

·显示地图指南针

·显示网格图层

初始化地图中心

/**

* 基础操作

*/

IMapController mapController = map.getController();

//初始化地图中心

mapController.setCenter(new GeoPoint(25.1,121.1));

//设置放缩等级

mapController.setZoom(14.1);

//双指旋转

map.setMultiTouchControls(false);

//双指旋转

RotationGestureOverlay mRotationGestu = new RotationGestureOverlay(map);

map.getOverlays().add(mRotationGestu);

//指南针

CompassOverlay  compassOverlay= new CompassOverlay(getApplicationContext(), new InternalCompassOrientationProvider(getApplicationContext()), map);

compassOverlay.enableCompass();

map.getOverlays().add(compassOverlay);

onResume();

//网格图层

LatLonGridlineOverlay2 latLonGridlineOverlay2 = new LatLonGridlineOverlay2();

map.getOverlays().add(latLonGridlineOverlay2);

/**

* 添加ItemOverlay

*/

ArrayList<OverlayItem> overlayItems = new ArrayList<>();

OverlayItem overlayItem = new OverlayItem("itemizedoverlay","overlayitem",new GeoPoint(21.1111,121.1111));

overlayItem.setMarker(getDrawable(R.drawable.marker_default));

overlayItems.add(overlayItem);

ItemizedOverlayWithFocus itemizedOverlayWithFocus = new ItemizedOverlayWithFocus(overlayItems,

        new ItemizedIconOverlay.OnItemGestureListener<OverlayItem>() {

            @Override

            public boolean onItemSingleTapUp(final int index, final OverlayItem item) {

                return true;

            }

            @Override
