Null Pointer Exception In Getview() Of Custom Adapter

I am using this Custom Adapter for my ListView: public class SideMenuAdapter extends BaseAdapter { private static final int TYPE_MAX_COUNT = 2; private static LayoutInflat

Solution 1:

You should initialize vi before your vi.setTag(holder);

Solution 2:

Try this, might help u...

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

    ViewHolderholder=newViewHolder();
    Viewvi= convertView;
    if (vi == null) {
        LayoutInflaterinflater= ((Activity)activity).getLayoutInflater();
        vi = inflater.inflate(R.layout.side_menu_list_item, null);
        holder.mainText = (TextView) vi.findViewById(R.id.mainText_sideMenu);
        holder.sideText = (TextView) vi.findViewById(R.id.sideText_sideMenu);
        vi.setTag(holder);
    } else {

        holder = (ViewHolder) vi.getTag();
    }

    holder.mainText.setText(values[position]);
    if(position == 2){

        holder.sideText.setText("3");
        holder.sideText.setBackgroundResource(R.drawable.orange);
    }
    return convertView;
}
