基于这篇文章，我创建了一个RecyclerView的子类。支持任意数量的页眉和页脚的适配器。

虽然这似乎是一个解决方案，但我也认为这个东西应该由LayoutManager管理。不幸的是，我现在需要它，我没有时间从头开始实现StaggeredGridLayoutManager(甚至也没有从它扩展)。

我还在测试，但如果你想试试也可以。如果你发现有任何问题，请告诉我。

出于个人目的，我在@hister的基础上做了一个实现，但使用了继承。

我在抽象超类HeadingableRecycleAdapter中隐藏了实现细节机制(如向itemCount中添加1，从position中减去1)，通过 实现所需的方法从适配器像onBindViewHolder, getItemViewType和getItemCount，使该方法最终，并提供新的方法与隐藏的逻辑客户端:

onAddViewHolder (RecyclerView。ViewHolder holder, int position)， onCreateViewHolder (ViewGroup父), itemCount ()

这里是HeadingableRecycleAdapter类和一个客户端。我留下的标题布局有点硬编码，因为它符合我的需要。

public abstract class HeadingableRecycleAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {

    private static final int HEADER_VIEW_TYPE = 0;

    @LayoutRes
    private int headerLayoutResource;
    private String headerTitle;
    private Context context;

    public HeadingableRecycleAdapter(@LayoutRes int headerLayoutResourceId, String headerTitle, Context context) {
        this.headerLayoutResource = headerLayoutResourceId;
        this.headerTitle = headerTitle;
        this.context = context;
    }

    public Context context() {
        return context;
    }

    @Override
    public final RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        if (viewType == HEADER_VIEW_TYPE) {
            return new HeaderViewHolder(LayoutInflater.from(context).inflate(headerLayoutResource, parent, false));
        }
        return onCreateViewHolder(parent);
    }

    @Override
    public final void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
        int viewType = getItemViewType(position);
        if (viewType == HEADER_VIEW_TYPE) {
            HeaderViewHolder vh = (HeaderViewHolder) holder;
            vh.bind(headerTitle);
        } else {
            onAddViewHolder(holder, position - 1);
        }
    }

    @Override
    public final int getItemViewType(int position) {
        return position == 0 ? 0 : 1;
    }

    @Override
    public final int getItemCount() {
        return itemCount() + 1;
    }

    public abstract int itemCount();

    public abstract RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent);

    public abstract void onAddViewHolder(RecyclerView.ViewHolder holder, int position);

}



@PerActivity
public class IngredientsAdapter extends HeadingableRecycleAdapter {
    public static final String TITLE = "Ingredients";
    private List<Ingredient> itemList;


    @Inject
    public IngredientsAdapter(Context context) {
        super(R.layout.layout_generic_recyclerview_cardified_header, TITLE, context);
    }

    public void setItemList(List<Ingredient> itemList) {
        this.itemList = itemList;
    }

    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent) {
        return new ViewHolder(LayoutInflater.from(context()).inflate(R.layout.item_ingredient, parent, false));
    }

    @Override
    public void onAddViewHolder(RecyclerView.ViewHolder holder, int position) {
        ViewHolder vh = (ViewHolder) holder;
        vh.bind(itemList.get(position));
    }

    @Override
    public int itemCount() {
        return itemList == null ? 0 : itemList.size();
    }

    private String getQuantityFormated(double quantity, String measure) {
        if (quantity == (long) quantity) {
            return String.format(Locale.US, "%s %s", String.valueOf(quantity), measure);
        } else {
            return String.format(Locale.US, "%.1f %s", quantity, measure);
        }
    }


    class ViewHolder extends RecyclerView.ViewHolder {
        @BindView(R.id.text_ingredient)
        TextView txtIngredient;

        ViewHolder(View itemView) {
            super(itemView);
            ButterKnife.bind(this, itemView);
        }

        void bind(Ingredient ingredient) {
            String ingredientText = ingredient.getIngredient();
            txtIngredient.setText(String.format(Locale.US, "%s %s ", getQuantityFormated(ingredient.getQuantity(),
                    ingredient.getMeasure()), Character.toUpperCase(ingredientText.charAt(0)) +
                    ingredientText
                            .substring(1)));
        }
    }
}

HeaderView依赖于LayoutManager。默认的layoutmanager都不支持这一点，而且可能不会。ListView中的HeaderView创建了很多复杂性，但没有任何显著的好处。

我建议创建一个基本适配器类，如果提供的话，它可以为header添加项。不要忘记覆盖notify*方法来适当地偏移它们，这取决于header是否存在。

请随意使用我的图书馆，这里有。

它可以让你创建任何RecyclerView的头视图，使用LinearLayoutManager或GridLayoutManager只需一个简单的方法调用。

你可以把你的头和你的RecyclerView放在NestedScrollView中:

<android.support.v4.widget.NestedScrollView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        >

        <include
            layout="@layout/your_header"/>

        <android.support.v7.widget.RecyclerView
            android:id="@+id/list_recylclerview"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            />

    </LinearLayout>

</android.support.v4.widget.NestedScrollView>

为了让滚动正常工作，你需要在RecyclerView上禁用嵌套滚动:

myRecyclerView.setNestedScrollingEnabled(false);

也许http://alexzh.com/tutorials/multiple-row-layouts-using-recyclerview/会有帮助。它只使用RecyclerView和CardView。 这是一个适配器:

public class DifferentRowAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
    private List<CityEvent> mList;
    public DifferentRowAdapter(List<CityEvent> list) {
        this.mList = list;
    }
    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view;
        switch (viewType) {
            case CITY_TYPE:
                view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_city, parent, false);
                return new CityViewHolder(view);
            case EVENT_TYPE:
                view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_event, parent, false);
                return new EventViewHolder(view);
        }
        return null;
    }
    @Override
    public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
        CityEvent object = mList.get(position);
        if (object != null) {
            switch (object.getType()) {
                case CITY_TYPE:
                    ((CityViewHolder) holder).mTitle.setText(object.getName());
                    break;
                case EVENT_TYPE:
                    ((EventViewHolder) holder).mTitle.setText(object.getName());
                    ((EventViewHolder) holder).mDescription.setText(object.getDescription());
                    break;
            }
        }
    }
    @Override
    public int getItemCount() {
        if (mList == null)
            return 0;
        return mList.size();
    }
    @Override
    public int getItemViewType(int position) {
        if (mList != null) {
            CityEvent object = mList.get(position);
            if (object != null) {
                return object.getType();
            }
        }
        return 0;
    }
    public static class CityViewHolder extends RecyclerView.ViewHolder {
        private TextView mTitle;
        public CityViewHolder(View itemView) {
            super(itemView);
            mTitle = (TextView) itemView.findViewById(R.id.titleTextView);
        }
    }
    public static class EventViewHolder extends RecyclerView.ViewHolder {
        private TextView mTitle;
        private TextView mDescription;
        public EventViewHolder(View itemView) {
            super(itemView);
            mTitle = (TextView) itemView.findViewById(R.id.titleTextView);
            mDescription = (TextView) itemView.findViewById(R.id.descriptionTextView);
        }
    }
}

这是一个实体:

public class CityEvent {
    public static final int CITY_TYPE = 0;
    public static final int EVENT_TYPE = 1;
    private String mName;
    private String mDescription;
    private int mType;
    public CityEvent(String name, String description, int type) {
        this.mName = name;
        this.mDescription = description;
        this.mType = type;
    }
    public String getName() {
        return mName;
    }
    public void setName(String name) {
        this.mName = name;
    }
    public String getDescription() {
        return mDescription;
    }
    public void setDescription(String description) {
        this.mDescription = description;
    }
    public int getType() {
        return mType;
    }
    public void setType(int type) {
        this.mType = type;
    }
}
