Android-如何在列表视图的页脚中添加网格视图
我有一个网格视图，我想在listview的页脚中添加，因为我希望这个页面应该具有整页滚动功能。
这是我的代码，我用我的网格视图适配器设置我的网格视图，但它在footer.i中显示空白有两个xml，一个用于标题，另一个仅用于网格视图。
GalleryGridViewAdapter
public class GalleryMainActivityGridViewAdapter extends BaseAdapter {
/**

*
* @param c
* @param resultArray
*
*/
public GalleryMainActivityGridViewAdapter(Context c, ArrayList<HashMap<String,String>>
resultArray) {
mContextGridView = c;
galleryArray = new ArrayList<HashMap<String, String>>();
galleryArray = resultArray;
sl = new GallerySmartLazyLoader(mContextGridView);
}
public int getCount() {
return galleryArray.size();
}
public Object getItem(int position) {
return null;
}
public long getItemId(int position) {
return 0;
}
/**
* Description:This method returns a bitmap related to drawable.
*
* @param bitmapUrl

*/
public Bitmap getBitmap(String bitmapUrl) {
URL url;
try {
System.out.println("bitmapUrl :" + " bitmapUrl : " + bitmapUrl);
url = new URL(bitmapUrl);
return BitmapFactory.decodeStream(url.openConnection().getInputStream());
} catch (Exception ex) {
ex.printStackTrace();

return null;

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网格视图适配器，并在滚动视图中找到了更好的平滑度...
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 {

}
}

holder.imgView_Grid_PlayVideo.setVisibility(View.GONE);
} else {

}
}
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;
}
}
