android - 在RECYCLER VIEW中添加页脚 View ？

我想在回收站 View 的底部添加页脚布局。下面是我的适配器 View ，它可以扩大页眉布局以及其他项目。感谢帮助!

public class SplitMembersAdapter extends RecyclerViewAdapter<SplitMember, SplitMemberViewHolder> {

        private final ArrayList<SplitMember> mSplitMembersList;
        private final ImageLoader mImageLoader;
        private static final int TYPE_HEADER = 0;
        private static final int TYPE_ITEM = 1;
        private int splitAmount;
        private boolean isAmountSplitted;

        public SplitMembersAdapter(ArrayList<SplitMember> members,ImageLoader imageLoader) {
            mSplitMembersList = members;
            mImageLoader = imageLoader;
        }

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

        @Override
        public int getItemViewType(int position) {
            if (isPositionHeader(position)) {
                return TYPE_HEADER;
            }

            return TYPE_ITEM;
        }

        private static boolean isPositionHeader(int position) {
            return position == 0;
        }

        @Override
        public SplitMemberViewHolder onCreateViewHolder(ViewGroup viewGroup, int viewType) {
            View itemView = LayoutInflater.from(viewGroup.getContext()).
                    inflate(R.layout.split_member_item_layout, viewGroup, false);
            return new SplitMemberViewHolder(itemView);
        }

        @Override
        public void onBindViewHolder(SplitMemberViewHolder viewHolder, int position) {
            SplitMember contact = mSplitMembersList.get(position);
            viewHolder.splitMemAmount.setText(String.format("%.2f", contact.getShare()));
            viewHolder.splitMemberColor.setBackgroundColor(contact.getColor());
            if (position == TYPE_HEADER){
                viewHolder.splitMemName.setText("You");
                mImageLoader.loadImage(contact.getImg(),
                        viewHolder.splitMemImg, R.drawable.empty_user_placeholder);
            }


            else {
                viewHolder.splitMemName.setText(contact.getName());
                mImageLoader.loadImage(Utils.getProfileImageUrl(contact.getImg()),
                        viewHolder.splitMemImg,R.drawable.empty_user_placeholder);
            }

        }
    }

    class SplitMemberViewHolder extends RecyclerView.ViewHolder {

        public BezelImageView splitMemImg;
        public TextView splitMemName;
        public TextView splitMemAmount;
        public View splitMemberColor;

        public SplitMemberViewHolder(View itemView) {
            super(itemView);
            splitMemberColor = itemView.findViewById(R.id.member_color);
            splitMemImg = (BezelImageView) itemView.findViewById(R.id.member_profile_image);
            splitMemName = (TextView) itemView.findViewById(R.id.member_name);
            splitMemAmount = (TextView) itemView.findViewById(R.id.member_amount);
        }
    }

最佳答案

与添加页眉类似，也添加页脚。

public class SplitMembersAdapter extends RecyclerViewAdapter<SplitMember, SplitMemberViewHolder> {

        private final ArrayList<SplitMember> mSplitMembersList;
        private final ImageLoader mImageLoader;
        private static final int TYPE_HEADER = 0;
        private static final int TYPE_ITEM = 1;
        private static final int TYPE_FOOTER = 2;
        private int splitAmount;
        private boolean isAmountSplitted;

        public SplitMembersAdapter(ArrayList<SplitMember> members,ImageLoader imageLoader) {
            mSplitMembersList = members;
            mImageLoader = imageLoader;
        }

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

        @Override
        public int getItemViewType(int position) {
            if (isPositionHeader(position)) {
                return TYPE_HEADER;
            }ELSE if (isPositionFooter(position)) {
                return TYPE_Footer;
            }
            return TYPE_ITEM;
        }

        private static boolean isPositionHeader(int position) {
            return position == 0;
        }

        private static boolean isPositionFooter(int position) {
            return position == mSplitMembersList.size()-1;
        }

        @Override
        public SplitMemberViewHolder onCreateViewHolder(ViewGroup viewGroup, int viewType) {

            switch(viewType){
               case TYPE_HEADER:
                 //return header view holder;
               break;
               case TYPE_ITEM:
                 //return item view holder;
                break;
               case TYPE_FOOTER:
                 //return footer view holder;
               break;
           }
        }

        @Override
        public void onBindViewHolder(SplitMemberViewHolder viewHolder, int position) {
               switch(getItemViewType(position)){
               case TYPE_HEADER:
                 //bind header data;
               break;
               case TYPE_ITEM:
                 //bind item data
                break;
               case TYPE_FOOTER:
                 //bind footer data.
               break;
           }
        }
    }

    class SplitMemberViewHolder extends RecyclerView.ViewHolder {

        public BezelImageView splitMemImg;
        public TextView splitMemName;
        public TextView splitMemAmount;
        public View splitMemberColor;

        public SplitMemberViewHolder(View itemView) {
            super(itemView);
            splitMemberColor = itemView.findViewById(R.id.member_color);
            splitMemImg = (BezelImageView) itemView.findViewById(R.id.member_profile_image);
            splitMemName = (TextView) itemView.findViewById(R.id.member_name);
            splitMemAmount = (TextView) itemView.findViewById(R.id.member_amount);
        }
    }
