Android GridView如何在适配器中添加头部？

3

我成功地更新了适配器的标题视图，包括在单个屏幕内的ListView、HeaderView（来自ListView）和GridView。问题是由于ListView和HeaderView显示相同的项，我想隐藏ListView以避免出现。我该如何做呢？

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    View rootView = inflater.inflate(R.layout.fragment_home, container, false);

    final Context gridContext = rootView.getContext();
    gridView = (GridViewWithHeaderAndFooter) rootView.findViewById(R.id.grid);

    this.inflaterGeneral = inflater;
    headerView = inflaterGeneral.inflate(R.layout.cell_fragment_home_header_list, null);
    listViewHeader = (ListView) headerView.findViewById(R.id.listViewHeader);
    rootView.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));

    return rootView;
}

我的ImageAdapter

class ImageAdapterHeader extends BaseAdapter {
    private Context context;
    private final String[] mobileValues;

    private TextView t;

    public ImageAdapterHeader(Context context, String[] mobileValues) {
        this.context = context;
        this.mobileValues = mobileValues;
    }

    public View getView(int position, View convertView, ViewGroup parent) {

        LayoutInflater inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        //View v = convertView;
        ViewHolder holder;

        final Item i = itemVideo.get(position);
        if (i != null) {
            final VideoDetail ei = (VideoDetail) i;

            //begin
            if (convertView == null) {
                convertView = inflater.inflate(R.layout.cell_fragment_home_header, null);
                holder = new ViewHolder();
                holder.imgThumbnail = (ImageView) convertView.findViewById(R.id.imgThumbnail);
                holder.txtDuration = (Button) convertView.findViewById(R.id.txtDuration);
                holder.txtTitle = (TextView) convertView.findViewById(R.id.txtTitle);
                holder.txtName = (TextView) convertView.findViewById(R.id.txtName);
                holder.txtView = (TextView) convertView.findViewById(R.id.txtView);
                holder.txtComment = (TextView) convertView.findViewById(R.id.txtComment);
                convertView.setTag(holder);
            } else {
                holder = (ViewHolder) convertView.getTag();
            }

            holder.txtDuration.setText(ei.getDuration());
            holder.txtTitle.setText(ei.getTitle());
            holder.txtView.setText(ei.getViewCount());
            holder.txtComment.setText(ei.getLikeCount());

            Picasso.with(this.context)
                    .load(ei.getDetailPreview().replace(" ", "%20"))
                    .error(R.drawable.ic_launcher).into(holder.imgThumbnail);

            holder.imgThumbnail.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    getActivity().runOnUiThread(new Runnable() {
                        public void run() {

                            Intent intent = new Intent(getContext(), VideoPlayerActivity.class);
                            intent.putExtra("videoId", ei.getVideoId());
                            intent.putExtra("title", ei.getTitle());
                            intent.putExtra("artistName", ei.getArtistName());
                            intent.putExtra("view", ei.getViewCount());
                            intent.putExtra("like", ei.getLikeCount());
                            startActivity(intent);

                        }
                    });

                }
            });
        } else {
            System.out.println("Item Null");
        }
        //end
        return convertView;
    }

我能看一下你的布局xml吗？ - Minh Bui

@MinhBui 我想要像这样做 gridView.addHeaderView(ListView); .. 你能给我一些建议吗？ - Driyanto Saputro

尝试使用 [HeaderGridView][1]，它是 GridView 的子类。希望能对您有所帮助。
