android - Listview: Only one list item with multiple textviews

Question

I need to show multiple text views in only one list item and the rest of the list view items will have just one textview.

How do I achieve this? Any samples or tutorials you can point me at?

Thank you.

Make your own adapter:

BaseAdapter already provieds methods for working with different View types (different layout for list item cells) and to effektivly recycle views:

• getViewTypeCount(): The count of how many different Views (layouts) are present.

• getItemViewType(): Returns a integer to identify the view type of the item in the cell. Note the internally BaseAdapter implementation uses an array. Therefore your values returned here must be from 0 to n. You are not allowed to skip indexes.

  public class MyAdapter extends BaseAdapter {

  private final int VIEW_TYPE_NORMAL = 0;
  private final int VIEW_TYPE_4_TEXTS = 1;
  
  /**
   * The inflater for
   */
  protected LayoutInflater inflater;
  protected Context context;
  
  public MyAdapter(Context context) {
      this.context = context;
      this.inflater = (LayoutInflater) context
              .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
  }
  
  @Override
  public int getViewTypeCount() {
      // There are two view types
      return 2;
  }
  
  @Override
  public int getItemViewType(int position) {
      if (position == 0)
          return VIEW_TYPE_4_TEXTS;
      else
          return VIEW_TYPE_NORMAL;
  }
  
  @Override
  public View getView(int position, View convertView, ViewGroup parent) {
      int type = getItemViewType(position);
      if (convertView == null) {
          convertView = newView(type, parent);
      }
      bindView(position, type, convertView);
      return convertView;
  }
  
  @Override
  public long getItemId(int position) {
      return 0; // replace it with your id, if you have stable ids in your
                  // adapter
  }
  
  /** Inflates the correct view accorind the view type **/
  public View newView(int type, ViewGroup parent) {
  
      if (VIEW_TYPE_4_TEXTS == type) {
          View view = inflater.inflate(R.layout.your_layout_with_4_textviews,
                  parent, false);
          view.setTag(new ViewHolder4TextViews(view)); // ViewHolder pattern
  
          return view;
      }
  
      // Otherwise its a normal item with VIEW_TYPE_NORMAL
      View view = inflater
              .inflate(R.layout.your_normal_layout, parent, false);
      view.setTag(new NormalViewHolder(view)); // ViewHolder pattern
  
      return view;
  
  }
  
  /** Bind the data for the specified {@code position} to the {@code view}. */
  public void bindView(int position, int type, View view) {
  
      if (VIEW_TYPE_4_TEXTS == type) {
          // set the 4 text view values
          ViewHolder4TextViews holder = (ViewHolder4TextViews) view.getTag();
  
          holder.textview1.setText("...");
          holder.textview2.setText("...");
          holder.textview3.setText("...");
          holder.textview4.setText("...");
  
      } else {
          // VIEW_TYPE_NORMAL
          NormalViewHolder holder = (NormalViewHolder) view.getTag();
  
          holder.textview.setText("...");
      }
  
  }
  

  }
