Question

如上图所示，我无法单击包含值15值的单元格。我发现它每13个单元重复一次。在下面，我还将显示适配器类。有人可以帮我找到这个问题。预先感谢。

public class OptionAdapter extends RecyclerView.Adapter<OptionAdapter.OptionViewHolder> implements ProductDetailAdapter,

private int mPriceJudge;

public OptionAdapter(Context context, Store store, OptionInfo optionInfo) {
    mContext = context;
    mOptionInfo = optionInfo;
    mSelectionType = optionInfo.getSelectionType();
    mOptionList = optionInfo.getData();
    for (Option option : mOptionList) {
        if (option.isSelected()) {
            mSelectedCount++;
        }
    }

    mPriceJudge = PriceUtil.priceJudge(store);
}

    return viewHolder;

此代码添加了单元格单击方法和其他与适配器相关的基本功能。我有一个问题，就是具体如何无法单击这些单元格。从回收者的角度来看，这是非常奇怪的行为。

Answer 1

您正在您的 bindOption 方法中设置viewHolder.mLayout.setClickable(false);。

在其他情况下，使您的viewHolder.mLayout可点击

Answer 2

在构造函数之后的OptionViewHolder类中执行类似的操作。

mLayout.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                int position=getAdapterPosition();
                itemListener.onClicked(position);
            }
        });

itemListener是您必须调用mainActivity的接口，在该接口中初始化了适配器。

interface ItemListener{
    void onClicked(int pos);
}
ItemListener itemListener;

public void setItemListener(ItemListener itemListener) {
    this.itemListener = itemListener;
}

单击索引视图即可从您的活动中执行下一步操作。

public class viewHolder extends RecyclerView.ViewHolder {
        ImageView pimg, favorite;
        TextView pname, pprice, prating;

        public viewHolder(View itemView) {
            super(itemView);
            pimg = (ImageView) itemView.findViewById(R.id.pimg);
            favorite = (ImageView) itemView.findViewById(R.id.favorite);
            pname = (TextView) itemView.findViewById(R.id.pname);
            pprice = (TextView) itemView.findViewById(R.id.pprice);
            prating = (TextView) itemView.findViewById(R.id.prating);

                itemView.setOnClickListener(new View.OnClickListener() {
                @Override
                    public void onClick(View v) {
                        onItemClickListener.onItemClick(getAdapterPosition(), v);
                    }
                });
        }

    public void setOnItemClickListener(OnItemClickListener onItemClickListener) {
        this.onItemClickListener = onItemClickListener;
    }

    public interface OnItemClickListener {
        void onItemClick(int position, View v);
    }
