android listview给出了nullpointerexception

Question

我有这个ListView,当我启动应用程序时,它给出一个空指针异常,但如果视图是GONE,它不会给出任何错误,

lVers = (ListView) view.findViewById(R.id.lVers);

用适配器

RechercheAdapter adapter2 = new RechercheAdapter(getActivity(), R.layout.elem_recherche, listPaysVers);
lVers.setAdapter(adapter2);

这是适配器类

public class RechercheAdapter extends ArrayAdapter<Pays> {

        Context context;
        ArrayList<Pays> data;

        public RechercheAdapter(Context context, int textViewResourceId, ArrayList<Pays> d) {
            super(context, textViewResourceId, d);
            this.data = d;
        }

        @Override
        public int getCount() {
            // TODO Auto-generated method stub
            return data.size();
        }

        @Override
        public Pays getItem(int position) {
            // TODO Auto-generated method stub
            return data.get(position);
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            Pays p = data.get(position);

            LayoutInflater inflater = (LayoutInflater) getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            View v = inflater.inflate(R.layout.elem_recherche, null);

            ImageView drap = (ImageView) v.findViewById(R.id.drap);
            drap.setImageDrawable(Utils.getBitmapFromBase64FullSize(p.getDreapeau64(), getActivity()));

            TextView nom = (TextView) v.findViewById(R.id.nom);
            nom.setText(p.getPays());

            return convertView;
        }

    }

当我尝试启动应用程序时,我得到一个nullpointerexception,

任何人都知道发生了什么？谢谢

Answer 1

返回视图V不转换View或

   convertView=inflater.inflate(R.layout.elem_recherche, null);
