私はmergeAdapterを使用して、複数のリストビューを問題なくマージしています。そして今、それを使って上部のリストビュー、中央の水平スクロールビュー、下部の別のリストビューをマージしたいのですが、これまでのところ...方法がわかりませんでした。 。誰かが私に手を差し伸べてくれたら素晴らしいと思います...

以下は私の既存のコードです。

MyActivity

public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.listview_a);

    lv = (ListView) findViewById(R.id.list_all);

    adapter=new MergeAdapter();
    infoArray = new ArrayList<Infos>();
            photoArray = new ArrayList<Photos>();
    commentArray = new ArrayList<Comments>();
    infoAdapter = new InfoAdapter(MyActivity.this, R.layout.info_list_layout, infoArray);
    /// photoAdapter = new PhotoAdapter(MyActivity.this, R.layout.photo_hscroll_layout, photoArray); /// STUCK
    commentAdapter = new CommentAdapter(MyActivity.this, R.layout.comment_list_layout, commentArray);
    lv.setTextFilterEnabled(true);
    adapter.addAdapter(infoAdapter);
    /// adapter.addAdapter(photoAdapter); //// STUCK
    adapter.addAdapter(commentAdapter);

    lv.setAdapter(adapter);
    try {
        new stuffSync().execute("http://www.StuckForDays.com/json");
    } catch(Exception e) {}

}

private class stuffSync extends AsyncTask<String, Integer, stuffDetail> {

    protected stuffDetail doInBackground(String... urls) {
        stuffDetail list = null;
        int count = urls.length;

        for (int i = 0; i < count; i++) {
            try {           
                //rest client
                RestClient client = new RestClient(urls[i]);
                try {
                    client.Execute(RequestMethod.GET);
                } catch (Exception e) {
                    e.printStackTrace();
                }

                String json = client.getResponse();

                list = new Gson().fromJson(json, stuffDetail.class);

                //
            } catch(Exception e) {}
        }
        return list;
    }

    protected void onProgressUpdate(Integer... progress) {

    }

    protected void onPostExecute(stuffDetail list) {

        List<Infos> info = list.getInfo();
         for (Infos info2 : info) {
            infoArray.add(info2);
        }
         List<Photos> photos = list.getPhotos();
         for (Photos photo : photos) {
            photoArray.add(photo);
            System.out.println(photo);
        }
         List<Comments> comments = list.getComments();
         for (Comments comment : comments) {
            commentArray.add(comment);
        }
        infoAdapter.notifyDataSetChanged();
        // photoAdapter.notifyDataSetChanged();  //// STUCK
        commentAdapter.notifyDataSetChanged();
    }

}

infoAdapterとcommentAdapter(ほぼ同じ)

public class InfoAdapter extends ArrayAdapter<Infos> {
int resource;
String response;
Context context;
private LayoutInflater dInflater;

public InfoAdapter(Context context, int resource, List<Infos> objects) {
        super(context, resource, objects);
        this.resource = resource;
        dInflater = LayoutInflater.from(context);
}
static class ViewHolder {
    TextView realname;
    TextView nickname;
}
public View getView(int position, View convertView, ViewGroup parent)
{
    ViewHolder holder;

    Infos lm = (Infos) getItem(position);

    //Inflate the view
    if(convertView==null)
    {
        convertView = dInflater.inflate(R.layout.info_list_layout, null);
        holder = new ViewHolder();
        holder.realname = (TextView) convertView.findViewById(R.id.realname);
        holder.nickname = (TextView) convertView.findViewById(R.id.nickname);

        convertView.setTag(holder);
    }
    else
    {
        holder = (ViewHolder) convertView.getTag();
    }

    holder.realname.setText(lm.getRealName());
    holder.nickname.setText(lm.getNickname());


    return convertView;
}
}

私の写真json

{
     "photos" : [
  {
     "thumbnail" : "http://www.myserver.com/01.jpg"
  },
  {
     "thumbnail" : "http://www.myserver.com/02.jpg"
  },
  {
     "thumbnail" : "http://www.myserver.com/03.jpg"
  }
]}

そして今、私はphotoArrayを取得して中央セクションの水平スクロールビューを作成する方法に固執しています... jsonを取得してphotoArrayに追加することができますが、抽出してビューを作成して表示する方法がわかりません。

よろしくお願いします

i think problem solve with horizontal scroll view.. this is a custom control..

            }
        }

    };



}

and you can set data in this same as a custom listadapter in listview.

here is the custom adapter

private class ListAdapter extends ArrayAdapter<bin> { // --CloneChangeRequired
        private ArrayList<bin> mList; // --CloneChangeRequired

        ImageView img;
        TextView title;
        String id;

        public ListAdapter(Context context, int textViewResourceId,
                ArrayList<bin> list) { // --CloneChangeRequired
            super(context, textViewResourceId, list);
            this.mList = list;
            imageLoader = new ImageLoader(YoutubeplayerActivity.this

you can bind data in horizontal listview

HorizonatlListView hv = (HorizontalListView) findviewbyId(R.id.hv1);
hv.setadater(new ListAdapter(getApplicationContext,R.id.hv1,ArrayList<bin>));
