android – 如何在触摸Uber等地图时切换 *** 作栏

概述我已经实现了一个地图,其行为类似于Uber应用程序,即在中心销钉,并在销钉下方映射拖动,并且销钉从地图获取位置.但是我无法实现触摸事件来切换动作栏,正好是优步.请帮我实现该功能.首先我使用了支持地图片段但是设置触摸事件需要一个视图,所以稍后我使用了MapView.Below是我的代码： package com.example.myfastapp;import java.util.List;i 我已经实现了一个地图,其行为类似于Uber应用程序,即在中心销钉,并在销钉下方映射拖动,并且销钉从地图获取位置.但是我无法实现触摸事件来切换动作栏,正好是优步.请帮我实现该功能.首先我使用了支持地图片段但是设置触摸事件需要一个视图,所以稍后我使用了MapVIEw.Below是我的代码：

解决方法 onCamerachangelistener已被弃用,但好消息是谷歌已经发布了3个新的监听器.

见：GoogleMap.OnCameraChangeListener

This interface was deprecated.

Replaced by GoogleMap.OnCameraMoveStartedListener,GoogleMap.OnCameraMoveListener and GoogleMap.OnCameraIDleListener. The order in which the deprecated onCameraChange method will be called in relation to the methods in the new camera change Listeners is undefined.

我已经使用了这些听众,现在我可以在地图上获得保持和释放事件.
