我需要帮助通过Android personnal项目（库存列表）中的项目集合实现滑动手势。我已经看到了很多例子，但我似乎无法正确地实现它

应用程序很简单。它只是一个清单（InventairesPieces），实现为项目（PieceModel）的滚动列表（InventairesPiecesActivity和InventairesPiecesFragment），单击一个项目后，详细信息（PieceViewActivity和PieceViewFragment）将在另一个活动中打开

在详细信息活动（PieceViewActivity和PieceViewFragment）中，我希望能够滑动accross项，而不是每次都返回滚动列表

到目前为止，我尝试将“ViewPager”设置为一个适配器，该适配器在我的片段（PieceViewFragment）上扩展FragmentStatePagerAdapter，但它不能正常工作：

*单击项目时，无论单击哪个项目，都会显示列表中的第一个项目。动作栏中的标题也不匹配*

下面是“PieceViewActivity”类：

}

下面是“PieceViewFragment”类（详细信息或卡片）：

}

下面是“InventairesPiecesFragment”类，单击滚动列表中的项目：
