I am making an Custom listview with Custom Adapter extending BaseAdapter. Now I want to set a different layout only for first row and another layout for all other rows. I am using this code but it sets the special layout for 1st row and also repeats it after every 5/6 rows. How can I fix it and can set it only for 1st row and another layout for all other rows.
public class NewsAdapter extends BaseAdapter {
private Context context;
List<News> newsList;
private Typeface customBanglaFont;
private LayoutInflater inflater;
ImageLoader imageLoader = AppController.getInstance().getImageLoader();
public NewsAdapter(Context context, List<News> newsList){
this.context = context;
this.newsList = newsList;
}
@Override
public int getCount() {
return newsList.size();
}
@Override
public Object getItem(int arg0) {
return newsList.get(arg0);
}
@Override
public long getItemId(int arg0) {
return arg0;
}
@Override
public View getView(int position, View convertView, ViewGroup viewGroup) {
View row;
row = convertView;
ViewHolder holder=null;
if(row == null){
if(position == 0){
inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row =inflater.inflate(R.layout.row_single_big_view,viewGroup,false);
}
else{
inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row =inflater.inflate(R.layout.row_single_default,viewGroup,false);
}
holder = new ViewHolder(row);
row.setTag(holder);
}
else{
holder = (ViewHolder) row.getTag();
}
if (imageLoader == null){
imageLoader = AppController.getInstance().getImageLoader();
}
final News news = newsList.get(position);
customBanglaFont = Typeface.createFromAsset(viewGroup.getContext().getAssets(), "fonts/SolaimanLipi.ttf");
holder.newsTitleView.setTypeface(customBanglaFont);
holder.newsTitleView.setText(news.getTitle());
holder.thumbNail.setImageUrl(news.getFeaturedImgSrc(), imageLoader);
return row;
}
}
/**

class ViewHolder{
TextView newsTitleView;
NetworkImageView thumbNail;
public ViewHolder(View v) {
// TODO Auto-generated constructor stub
newsTitleView = (TextView) v.findViewById(R.id.news_title);
thumbNail = (NetworkImageView) v.findViewById(R.id.news_image);
}
}
Why don't you use the Header functionality already built into ListView for this specific thing.
The docs: http://developer.android.com/reference/android/widget/ListView.html#addHeaderView%28android.view.View,%20java.lang.Object,%20boolean%29
or a SO question: Using ListView : How to add a header view?
your attempting is wrong. Your way you will be able to inflate just one layout. In fact, after the method returns the first time,
convertView is not null
. To fix quickly you could overridegetViewTypeCount
andgetItemViewType
. This way you will getconvertView
s eqaul to the return value ofgetViewTypeCount
, or you could just add the first item as header view for theListView
