Android-如何在 ListView 的页脚添加 GridView

Question

我有一个 GridView ，我想将其添加到 ListView 的页脚中，因为我希望此页面应该具有完整的页面滚动功能。

这是我的代码，我在其中使用我的 GridView 适配器设置我的 GridView ，但它在页脚中显示为空白。我有两个 xml，一个用于页眉，另一个仅用于 GridView 。

public class GalleryMainActivityGridViewAdapter extends BaseAdapter {

最后我得到了我自己的问题的答案我已经使用 android 查询库创建了新的适配器并在我的屏幕上实现了新的 GridView 适配器并发现 ScrollView 中的平滑度更高......

这是我的代码

public class GalleryMainActivityGridViewAdapter extends BaseAdapter {

    AQuery listAQ;
    Context mContext;
    int layoutResourceId;
    ArrayList<HashMap<String, String>> dataArray;

    public GalleryMainActivityGridViewAdapter(Context context, ArrayList<HashMap<String, String>> resultArray) {
        this.mContext = context;
        // this.layoutResourceId = layoutId;
        this.dataArray = resultArray;
        listAQ = new AQuery(mContext);
        // aa = new ArrayAdapter<Photo>(mContext, layoutResourceId);
    }

    public int getCount() {
        return dataArray.size();
    }

    public Object getItem(int position) {
        return position;
    }

    public long getItemId(int position) {
        return 0;
    }

    @SuppressWarnings("deprecation")
    public View getView(int position, View convertView, ViewGroup parent) {

        if (convertView == null) {
            convertView = ((LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.gallery_main_page_grid_item, parent, false);
        }
        Holder holder = new Holder();

        AQuery aq = listAQ.recycle(convertView);

        holder.imgView_Grid_Thumbnail_Gallery = (ImageView) convertView.findViewById(R.id.imgView_Grid_Thumbnail_Gallery);

        if (holder.imgView_Grid_Thumbnail_Gallery != null) {
            aq.id(holder.imgView_Grid_Thumbnail_Gallery.getId()).image(dataArray.get(position).get("thumbUrl") + "/11");
        }

        holder.txtView_Grid_Name_Gallery = (TextView) convertView.findViewById(R.id.txtView_Grid_Name_Gallery);
        if (holder.txtView_Grid_Name_Gallery != null) {
            aq.id(holder.txtView_Grid_Name_Gallery.getId()).text(dataArray.get(position).get("user_name"));
            Typeface txtViewForName = Typeface.createFromAsset(convertView.getContext().getAssets(), "fonts/arial_bold.ttf");
            holder.txtView_Grid_Name_Gallery.setTypeface(txtViewForName);

        }

        holder.imgView_GridItem_Gallery = (ImageView) convertView.findViewById(R.id.imgView_GridItem_Gallery);

        if (holder.imgView_GridItem_Gallery != null) {

            Bitmap cachedImage = aq.getCachedImage(R.drawable.loading);
            String publicUrl = dataArray.get(position).get("publicUrl") + "/13";
            if (aq.shouldDelay(convertView, parent, publicUrl, 0)) {
                aq.id(holder.imgView_GridItem_Gallery.getId()).image(cachedImage, 0.75f);
            } else {
                aq.id(holder.imgView_GridItem_Gallery.getId()).image(publicUrl, true, true, 0, 0, cachedImage, 0, 0.75f);
            }
        }

        // if (holder.txtView_Grid_Views_Gallery != null) {
        //
        // }
        holder.imgView_Grid_PlayVideo = (ImageView) convertView.findViewById(R.id.imgView_Grid_PlayVideo);
        if (holder.imgView_Grid_PlayVideo != null) {

            if (dataArray.get(position).get("filetype").toString().equals("1")) {
                holder.imgView_Grid_PlayVideo.setVisibility(View.GONE);
            } else {
                holder.imgView_Grid_PlayVideo.setVisibility(View.VISIBLE);
            }
        }

        return convertView;

    }

    class Holder {
        ImageView imgView_Grid_PlayVideo;
        ImageView imgView_Grid_Thumbnail_Gallery;
        TextView txtView_Grid_Views_Gallery;
        TextView txtView_Grid_Name_Gallery;
        ImageView imgView_GridItem_Gallery;
    }

}
