Привет, я хочу установить разные изображения для каждой строки списка, который прикреплен к CustomBaseAdapter.
У меня уже есть код, но я получаю принудительное закрытие с помощью NullPointer в строке 49 адаптера.
convertView = mInflater.inflate(R.layout.test, null);
Может кто-нибудь помочь решить эту проблему?
Заранее спасибо.
Код основной деятельности:
private static int icons[] = {R.drawable.ic_dialog_time, R.drawable.eur};
...
ArrayList<SearchResults> searchResults = GetSearchResults();
kp.setAdapter(new MyCustomBaseAdapter(AndroidLogin.this, searchResults, icons));
Код решения CustomBaseAdapter:
public class MyCustomBaseAdapter extends BaseAdapter {
public int images[];
private static ArrayList<SearchResults> searchArrayList;
private LayoutInflater mInflater;
public static class ViewHolder {
ImageView imgViewLogo;
TextView txtNaam;
TextView txtWaarde;
}
public MyCustomBaseAdapter(Context context, ArrayList<SearchResults> results, int[] images) {
super();
mInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
this.images = images;
searchArrayList = results;
}
public int getCount() {
return searchArrayList.size();
}
public Object getItem(int position) {
return searchArrayList.get(position);
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
holder = new ViewHolder();
convertView = mInflater.inflate(R.layout.test, null);
holder.imgViewLogo =(ImageView)convertView.findViewById(R.id.imgIcon);
holder.txtNaam = (TextView) convertView.findViewById(R.id.naam);
holder.txtWaarde = (TextView) convertView.findViewById(R.id.waarde);
convertView.setTag(holder);
}
else
{
holder = (ViewHolder) convertView.getTag();
}
holder.imgViewLogo.setImageResource(images[position%2]);
holder.txtNaam.setText(searchArrayList.get(position).getNaam());
holder.txtWaarde.setText(searchArrayList.get(position).getWaarde());
return convertView;
}
}
