卡片提供了纹理销毁接口，如果不销毁纹理可能造成内存泄漏、纹理id超出纹理管理器可容纳的个数导致后续纹理无法添加成功等情况。

核心接口

void com.autonavi.gbl.map.layer.BaseLayer.removeItem(String itemID)

int com.autonavi.gbl.map.layer.observer.IPrepareLayerStyle.clearLayerItem(BaseLayer pLayer,LayerItem pItem)

int com.autonavi.gbl.card.ITextureManager.destroyCustomTexture(int markerId)

boolean com.autonavi.gbl.map.MapView.destroyTexture(int resId)


说明：函数详情，请复制函数名称到在线API搜索

调用示例

\npublic class MapPrepareLayerStyle implements IPrepareLayerStyle {\n\t...\t\n\t@Override  图元删除回调\n    public void clearLayerItem(BaseLayer pLayer, LayerItem pItem) {\n        if (destroyCustomTexture)\n        {\n            /*< 获取卡片管理器 */\n            ITextureManager textureManager;\n            ...\n\n            /*< 获取要销毁的动态纹理ID */\n            int customeTextureId;\n            ...\n\n            textureManager.destroyCustomTexture(customeTextureId);\n        }        \n        else if (destroyStaticTexture)\n        {\n            /*< 获取要销毁的静态纹理ID */\n            int staticTextureId;\n            ...\n\n            /*< 获取视图 */\n            MapView mMapView;\n            ...\n\n            mMapView.destroyTexture(staticTextureId);\n        }\n\t}\t\n}
