将不同数量的TextViews添加到ArrayAdapter中的LinearLayout持有人

Question

I have a listview with CustomArrayAdapter,

want to add dynamically different amount of TextViews to LinearLayout Holder in that listView (like List of TextViews in each row)

  @Override
public View getView(final int position, View convertView, ViewGroup parent) {
    final ViewHolder holder;
    //String menu_opcja = getItem(position);
    SupleSubClass supleSubClass = getItem(position);


    if (convertView==null){
        convertView = inflater.inflate(R.layout.suplementacja_row, null);
        holder = new ViewHolder();
        holder.suplement = (TextView) convertView.findViewById(R.id.nazwa_suplementu);
        holder.opis = (TextView) convertView.findViewById(R.id.descr);
        holder.linearLayout = (LinearLayout)convertView.findViewById(R.id.linear_layout_test);
        convertView.setTag(holder);
    }
    else{
        holder = (ViewHolder) convertView.getTag();
    }

    holder.suplement.setText(supleSubClass.getName());
    holder.opis.setText(supleSubClass.getDescr());
    holder.linearLayout.setBackgroundColor(Color.CYAN);


    return convertView;

}


private static class ViewHolder{
    TextView suplement;
    TextView opis;
    LinearLayout linearLayout;

}

Answer 1

If you know how many types of layout you will need it is possible to use method:

getViewTypeCount() 

This method should return total number of unique layouts.

The next step is creating method:

getItemViewType(int position)

that will inform which layout to use for given position.

In getView() you need to inflate layout only if it is null and determine layout by getItemViewType(position)
