我正在尝试从 ListView 中删除一个未开始特定文本“Dev”的项目。但是当我删除一个项目并通过 notifydatasetChanged() 刷新回收列表时，应用程序崩溃了。这个问题已经被问过，我已经看到了所有的解决方案，但我找不到合适的解决方案。
EvelistAdapter.java
public class EvelistAdater extends RecyclerView.Adapter<EvelistAdater.ViewHolder> {
Context cxt;
ArrayList<Dbbean> adapterlist;
int row_index;
public EvelistAdater(Context cxt, ArrayList<Dbbean> list) {
adapterlist=list;
this.cxt=cxt;
Log.d("LIst count",""+adapterlist.size());
}
@Override
public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int viewType) {
View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.scanlistadp, viewGroup, false);
return new ViewHolder(view);
}
@Override
public void onBindViewHolder(ViewHolder holder, final int position) {
if(adapterlist.get(position).blename.startsWith("Dev")) {
holder.tv_country.setText(adapterlist.get(position).blename);
}else{
removeAt(position);
}
}
@Override
public int getItemCount() {
return adapterlist.size();
}
public class ViewHolder extends RecyclerView.ViewHolder{
TextView tv_country;
RelativeLayout layout;
ImageView setting;
public ViewHolder(View view) {
super(view);
tv_country = (TextView)view.findViewById(R.id.tshirtname);
setting = (ImageView) view.findViewById(R.id.setting);
layout = (RelativeLayout)view.findViewById(R.id.layout);
}
}
public void removeAt(int position) {
adapterlist.remove(position);
notifyDataSetChanged();
}
}
LOGCAT
