Question

这是我的形象：

This my image

如果我需要尝试任何事情，请建议我。

我的代码片段：

public class ShopFragment extends Fragment {

private  int imgShop[] = {R.drawable.thumbnail_01,
        R.drawable.thumbnail_02,
        R.drawable.thumbnail_03,
        R.drawable.thumbnail_04,
        R.drawable.thumbnail_05,
        R.drawable.thumbnail_06};
ViewPager pager;
SearchView searchView;

private int img[] = {R.drawable.scroll_view, R.drawable.scroll_view, R.drawable.scroll_view, R.drawable.scroll_view};


public ShopFragment() {
    // Required empty public constructor
}

private ArrayList<Shop> prepareShop() {

    ArrayList<Shop> shop = new ArrayList<>();
    for (int i = 0; i < imgShop.length; i++) {
        Shop shops = new Shop();
        shops.setShop_img(imgShop[i]);
        shop.add(shops);
    }
    return shop;
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_shop, container, false);




    pager = (ViewPager) view.findViewById(R.id.img_pager);
    ViewPagerAdapter viewPagerAdapter = new ViewPagerAdapter(getContext(), img);
    pager.setAdapter(viewPagerAdapter);


    RecyclerView recyclerView = (RecyclerView) view.findViewById(R.id.mRecyclerShop);
    RecyclerView.LayoutManager layoutmanager = new GridLayoutManager(getContext(), 3);
    recyclerView.setLayoutManager(layoutmanager);


    ArrayList<Shop> shops = prepareShop();
    ShopRecycleAdaptor adaptor = new ShopRecycleAdaptor(getContext(), shops);
    recyclerView.setAdapter(adaptor);

    return view;
}

我的适配器

public class ShopRecycleAdaptor extends RecyclerView.Adapter<ShopRecycleAdaptor.ViewHolder> {
private ArrayList<Shop> shop;
private Context context;
private int[] imgShop;



public ShopRecycleAdaptor(Context context, ArrayList<Shop> shop) {
    this.shop = shop;
    this.context = context;
}

@Override
public ShopRecycleAdaptor.ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
    View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.model_shop, viewGroup, false);
    return new ViewHolder(view);
}

@Override
public void onBindViewHolder(ShopRecycleAdaptor.ViewHolder holder, int position) {
    Picasso.with(context)
            .load(shop.get(position)
            .getShop_img())
            .into(holder.imgShop);
    holder.imgShop.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(v.getContext(), ShopType.class);
            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            intent.putExtra("shop", shop);
            v.getContext().startActivity(intent);
        }
    });
}


@Override
public int getItemCount() {
    return shop.size();
}

public class ViewHolder extends RecyclerView.ViewHolder {

    private ImageView imgShop;

    public ViewHolder(View view) {

        super(view);

        imgShop = (ImageView) view.findViewById(R.id.img_shop);
    }

}

这是我的错误

Answer 1

onClick类Parcelable？要将任何自定义类放入Bundle，该类必须实现Parcelable接口。见这里。

https://developer.android.com/reference/android/os/Parcelable.html

您的堆栈跟踪错误表明正在添加的信息实际上不符合Parcelable，因此导致问题的intent.putExtra("shop", shop);错误不是
