GIS的学习（二十一）在osmdroid 地图中添加marker 并添加事件

 

   我有 osmdroid，overlayswithfocus，当我们单击在覆盖的标注或弹出窗口显示，但我需要它回到正常的叠加时我触摸其他叠加图。所以，我需要帮助请。和我的添加叠加的 for 循环调用此函数。

   在osmdroid中添加marker并事件的实现。

  在osmdroid 地图中添加marker 并添加事件
     主要采用ItemizedOverlayWithFocus图层并添加
        ItemizedIconOverlay.OnItemGestureListener事件监听实现
