作为一个新手程序员,我不能为我的生活弄清楚我的代码在哪里失败.任何帮助将非常感激！

如果我遗漏了重要信息,请告诉我,我会更新这个问题.

在Fragment中启动它的代码：

@Override
    public void onActivityCreated(Bundle savedInstanceState){
        super.onActivityCreated(savedInstanceState);
        Intent i = getActivity().getIntent();

        if (i.getSerializableExtra("ChosenWorkorder") != null){

            Workorder selectedWorkorder = (Workorder) i.getSerializableExtra("ChosenWorkorder");                

            ArticlesListAdapter articlesListAdapter = new ArticlesListAdapter(getActivity(),R.layout.articles_list_row,selectedWorkorder.GetAllLines());

            ListView articlesList = (ListView) getActivity().findViewById(R.id.ArticlesList);
            articlesList.setAdapter(articlesListAdapter);

        }
    }

Custom ArrayAdapter：

public class ArticlesListAdapter extends ArrayAdapter<Line> {

    private List<Line> lineList;
    private Context context;

    public ArticlesListAdapter(Context context,int textViewResourceId,List<Line> objects) {
    super(context,textViewResourceId,objects);
        this.lineList = objects;
        this.context = context;
    }

    public int getCount() {
        return lineList.size();
    }

    public Line getItem(int position) {
        return lineList.get(position);
    }

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

    @SuppressLint("ViewHolder") /* Que? */
    public View getView(int position,View convertView,ViewGroup parent) {

        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View rowView = inflater.inflate(R.layout.articles_list_row,parent,false);

        TextView articleName = (TextView)     rowView.findViewById(R.id.textArticleName);
        EditText articleAmount = (EditText)     rowView.findViewById(R.id.textArticleAmount);

        Line articleLine = lineList.get(position);

        articleName.setText(articleLine.getLineArticleDescription());
        articleAmount.setText(articleLine.getLineArticleAmount().toString());

        return parent;      
    }
}

下面是LogCat日志以便澄清(对我而言,这意味着什么).
