Question

您好，我在片段视图中遇到了一个问题，即使形状发生了变化，每个片段都具有相同的RecyclerView图片，如下所示，每个片段中的结果相同：

因此，该图像仍与导入片段中的图像相同，并且无法删除事务，但是如果给定背景（如图片3），则该图像可能会丢失但无法使用，只能使用前一个图像进行堆叠。 / p>

这是我犯下的全部错误：

Adapter.java

    }

    public static class MyViewHolder extends RecyclerView.ViewHolder {
        TextView tv_title;
        ImageView tas_thumbnail;
        CardView card;
        public MyViewHolder(View itemView) {
            super(itemView);
            tv_title = itemView.findViewById(R.id.texttas);
            tas_thumbnail = itemView.findViewById(R.id.imagetas);
            card = itemView.findViewById(R.id.cardviewid);
        }
    }
}

我的问题是我仍然使用此代码，还是更改了适配器或其他一些代码以使其变得容易？原因是我在另一个页面上混合了来自另一页面的代码，所以不会发生。

Answer 1

我只是更改了列表，并为其创建了一个不同的适配器，但是在导入片段和第一张图片时，我只是使用了相同的列表，但是像这样的列表的不同集合

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));

仅位于每个页面上数组列表上的不同集合上

网格布局上的不同片段和不同项目使用recyclerview
