我已经实现了一个类似于uber应用程序的地图，即pin在中心，地图在pin下拖动，pin从地图中获取位置。但是我不能实现触摸事件来切换操作栏，只是Uber-do而已。请帮助我实现该功能。首先，我使用了支持映射片段，但要设置触摸事件，需要一个视图，因此稍后我使用了映射视图。下面是我的代码：

最佳答案
onCameraChangeListener已被弃用，但好消息是google已经发布了3个新的侦听器。
参阅：GoogleMap.OnCameraChangeListener
此接口已弃用。
替换为GoogleMap.OnCameraMoveStartedListener、GoogleMap.OnCameraMoveListener和GoogleMap.OnCameraIdleListener。不推荐的onCameraChange方法相对于新相机更改侦听器中的方法的调用顺序是未定义的。
我已经使用了这些侦听器，现在我可以在map上获取hold-and-release事件。
