在recylerview中的NPE oncreateviewholder android

这应该是一项简单的工作.我刚从api调用中获取数据,并希望在recyclerview中填充它.我做过这样的事情就像我猜的每个人一样.但是在这里,当视图项布局在适配器类中膨胀时,我得到空指针异常.我不知道如何解决它.

我的适配器类是

public class RecipeAdapter extends RecyclerView.Adapter {

private List recipeByIngredients;
private Context mContext;

public RecipeAdapter(List recipeByIngredients, Context mContext) {
    this.recipeByIngredients = recipeByIngredients;
    this.mContext = mContext;
}


@Override
public RecipeAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    final LayoutInflater mInflater = LayoutInflater.from(parent.getContext());
    final View itemView = mInflater.inflate(R.layout.recipe_item_layout, parent, false);

    return new ViewHolder(itemView);
}

@Override
public void onBindViewHolder(ViewHolder holder, int position) {

    RecipeByIngredients recipeByIngredient = recipeByIngredients.get(position);

    holder.tvUsedIngredients.setText(recipeByIngredient.getUsedIngredientCount() + " " + "ingredients used");
    holder.tvMissedIngredients.setText(recipeByIngredient.getMissedIngredientCount() + " " + "missed ingredients");

    Glide.with(mContext)
            .load(recipeByIngredient.getImage())
            .placeholder(R.drawable.recipe_placeholder)
            .error(R.drawable.recipe_placeholder)
            .into(holder.mainRecipePhoto);
}

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

public static class ViewHolder extends RecyclerView.ViewHolder{

    public ImageView mainRecipePhoto;
    public TextView tvUsedIngredients;
    public TextView tvMissedIngredients;

    public ViewHolder(View itemView) {
        super(itemView);

        mainRecipePhoto = (ImageView) itemView.findViewById(R.id.ivRecipe);
        tvMissedIngredients = (TextView) itemView.findViewById(R.id.tvMissedIngredients);
        tvUsedIngredients = (TextView) itemView.findViewById(R.id.tvUsedIngredients);
    }
 }
}

项目布局xml是

我得到的错误
