在自定义baseadapter中使用arraylist删除listview项位置错误

public class MyAdapter extends BaseAdapter {
    private ArrayList<String> mData;
    private Context mContext;

    public MyAdapter(Context context, ArrayList<String> data) {
        mContext = context;
        mData = data;
    }

    @Override
    public int getCount() {
        return mData.size();
    }

    @Override
    public Object getItem(int position) {
        return mData.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        ViewHolder holder;
        if (convertView == null) {
            convertView = LayoutInflater.from(mContext).inflate(R.layout.list_item, parent, false);
            holder = new ViewHolder();
            holder.textView = convertView.findViewById(R.id.text_view);
            holder.deleteButton = convertView.findViewById(R.id.delete_button);
            convertView.setTag(holder);
        } else {
            holder = (ViewHolder) convertView.getTag();
        }

        holder.textView.setText(mData.get(position));

        holder.deleteButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // 删除项
                mData.remove(position);
                notifyDataSetChanged();
            }
        });

        return convertView;
    }

    private static class ViewHolder {
        TextView textView;
        Button deleteButton;
    }
}
