Android百度地图轨迹播放暂停速度调控，进度调控
摘要：之前看到了百度地图的api以为Android的实现方式也是很简单的，结果百度地图的demo并没有Android的轨迹播放的demo，有的也是简单的轨迹播放并没有进度和速度的控制，最后只能是自己做的。 可以是实现小汽车轨迹的平滑移动，并且并且弹框的内容可以跟着小汽车的变化而变化。汽车轨迹播放的暂停与播放，进度的控制，速度的控制，并且如果车辆是移动到外面的还可以自动移动到屏幕中间 一：结果展示(因为gif的大小只能是5M所以录制的比较少 )
二：代码展示 activity的代码展示 这里请求的是本地的json格式的数据，但是里面也注释了HTTP的请求方式有需要的可以参考。 package com.boxin.truck.activity.manager; import android.annotation.SuppressLint; import android.content.Intent; import android.graphics.Point;
