长按标记我的RecyclerView中的一行（按）

Question

我需要帮助我RecyclerView。我在https://www.raywenderlich.com/126528/android-recyclerview-tutorial建立了一个普通的RecyclerView，现在我需要你的帮助。

我希望在长时间触摸（按下）时在我的RecylcerView中标记一条线（标记的线应该是灰色的），并且设备会发出短暂的振动，以在标记的行中显示删除图标。当行被标记时，我想显示删除图标而不是配置文件图像。点击设备上的后退按钮，我将删除此标记。我怎样才能做到这一点？谢谢你的帮助！

长按后排（按住）：

这是我的适配器：
