开发文档：开始云台控制
接口功能
对设备进行开始云台控制，开始云台控制之后必须先调用停止云台控制接口才能进行其他操作，包括其他方向的云台转动
请求地址
https
://open.ys7.com/api/lapp/device/ptz/start
请求方式
POST
子账户token请求所需最小权限
"Permission"
:"Ptz" "Resource"
:"Cam
:序列号
:通道号"
请求参数
参数名 类型 描述 是否必选
accessToken String 授权过程获取的access_token Y
deviceSerial String 设备序列号,存在英文字母的设备序列号，字母需为大写 Y
channelNo int 通道号 Y
direction int 操作命令：0-上，1-下，2-左，3-右，4-左上，5-左下，6-右上，7-右下，8-物理放大，9-物理缩小，10-调整近焦距，11-调整远焦距，16-自动控制 Y
speed int 云台速度：0-慢，1-适中，2-快，海康设备参数不可为0 Y 。停止云台控制

提示：建议停止云台接口带方向参数。
依据上述代码和开发文档检查为什么在操作云台有时候点击一个任一方向键后再松开这个方向键云台有时候会出现一直朝着这个方向在旋转，操作云台代码中有没有需要改进的地方
本文分享了关于在Android开发中遇到的android:maxWidth属性失效的问题，并总结了解决方案。关键在于设置android:adjustViewBounds为true且避免将android:layout_width设为match_parent。
