网格布局上的不同片段和不同项目使用recyclerview

Question

你好我在片段视图中有一个问题，每个片段都有相同的RecyclerView图片，即使形状已经改变，每个片段中的不同结果保持不变，如下所示：

因此图像仍然与导入片段相同，并且交易无法删除，但如果给出像图片3这样的背景，它可能会丢失但不能使用，只能使用前一个图像就像堆叠一样。

这是我的主要活动，使一切都错了：

我的问题是我仍然使用此代码或我更改了适配器或其他代码以使其变得简单？因为我在堆栈溢出时从另一个页面混合了代码，它不会发生。

Answer 1

我只是改变了列表，并为它做了一个不同的适配器，但在导入片段和第一张图片我只是使用相同的列表，但不同的列表集合，如此

lstTas = new ArrayList<>();
    lstTas.add(new Tas("Tas Serbaguna Sedang", "Kategori : Tas Lokal", "Deskripsi Tas : Tas serbaguna yang bisa menyimpan berbagai alat make up maupun perlengkapan lainnya", "Rp 70.000", R.drawable.greybag));
    lstTas.add(new Tas("Pouch Wanita Sedang", "Kategori : Pouch", "Deskripsi Tas : Dompet Pouch Trendy yang muat banyak barang dan trendy di bawa kemana saja", "Rp 20.000", R.drawable.pouch));
    lstTas.add(new Tas("Tas Pink Mini", "Kategori : Tas Import", "Deskripsi Tas : Tas Import mini bag yang bisa menyimpan peralatan mandi ataupun kebutuhan sehari - hari wanita", "Rp.120.000", R.drawable.pinkmini));
    lstTas.add(new Tas("Tote Bag Campus", "Kategori : Tas Import", "Deskripsi Tas : Tote Bag cocok untuk kalian yang masih kuliah untuk menyimpan perlengkapan kuliah", "Rp.90.000", R.drawable.totebag));
    lstTas.add(new Tas("Fold Tote Bag", "Kategori : Tas Import", "Deskripsi Tas : Tote Bag lipat yang bisa di lipat cocok untuk para remaja yang suka simple membawa barang saat berpergian", "Rp.100.000", R.drawable.totebagorange));

只是在每个页面的数组列表上的不同集合
