我愿执行《循环录象和录像带》中与“Info”相类似的材料。 我成功地执行了循环器电文,以显示图像和录像制品,但当ScrollListener在上时,我正在对录像物品进行铺设。 RerixrView。 SCROLL_STATE_DRAGGING 我正在利用ExoPlayer图书馆播放录像机。”
因此,如果拍摄了录像,如果循环器的电文不停播放,那么即使从名单上拍摄了另一个录像,该电文也会继续播放。 同时制作多个视频。
下面是我的执行适应方案

我在这里和在座程上都经历了几个问题,但是在循环器的电文中,所有这些都只是一个单一的观点类型。
Any suggestion how I could control the Video Player when the recyclerView is been scrolled? Or a better way I could implement the Instagram feeds like RecyclerView
