wxss 样式文件

.fold {
  position: absolute;
  top: 50vh;
  right: 10px;
  z-index: 3;
}
.unfold {
   position: absolute;
   top: 50vh;
   right: 10px;
   z-index: 3;
   display: flex;
   flex-direction: row;
}
.unfold .member-list {
  background-color: rgba(48, 40, 40, 0.7);
   width: 160px;
   display: flex;
   flex-direction: column;
   color: honeydew;
}
.fold-img {
  height: 32px;
  width: 32px;
}

js 文件

  _handFoldClick() {
    this.setData({
      isUserListShow: !this.data.isUserListShow
    })
  },

以上就是实现音视频组件添加其他view的相关逻辑，主要就是view需要用绝对定位实现。
