一、前言：

1. JzvdStd版本

implementation 'cn.jzvd:jiaozivideoplayer:7.0.5'

2. 问题描述

最开始使用JzvdStd进行正常播放是没问题的，如果点击全屏播放，然后又从全屏播放退出来，会导致控件不可见，除开视频，我底部是还有很多的控件的，但是现在它们都不可见了。如下图所示：

二、解决方法：

1. 在自定义布局外添加一层父布局：

           <LinearLayout
               android:layout_width="match_parent"
               android:layout_height="200dp">
            <com.sumansoul.mypaydemo.MyJzvdStd
                android:id="@+id/jz_video"
                android:layout_width="match_parent"
                android:layout_height="200dp" />
           </LinearLayout>

2. 自定义布局MyJzvdStd.java

 * 所有关于视频的逻辑都应该写在这里
