android - android程序无声停止

Question

我正在尝试更改我的 ListFragment 扩展的内容，但是发生了一些神秘的事情。

在我的 MainActivity 我有 ToFragment 并调用：

ToFragment.changeContent(newContent);

这个函数看起来像：

public class DataListFragment extends ListFragment {   
    CustomArrayAdapter mAdapter;
    public CustomArrayAdapter getAdapter() {
        return mAdapter;
    }
    @Override 
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        setEmptyText("");
        mAdapter = new CustomArrayAdapter(getActivity());
    }
    public void changeContent(ArrayList<FinalData> data) {
        System.out.println("first");
        mAdapter.setData1(data);
        System.out.println("second");
        mAdapter.notifyDataSetChanged();
        setListShown(true);
    }
}

最后，setData1 函数是：

public void setData1(ArrayList<FinalData> data) {
    System.out.println("third");
    clear();
    if (data != null) {
        for (FinalData appEntry : data) {
            add(appEntry);
        }
    }
}

当我运行我的程序时，它调用 changeContent() 函数，然后打印“first”，但不打印“second”和“third”。然后它什么都不做！没有例外，没有程序中断...它调用 mAdapter.setData1(data); 并消失。你有什么想法？

UPD：这是 CustomArrayAdapter 类：

public class CustomArrayAdapter extends ArrayAdapter<FinalData> {
    private final LayoutInflater mInflater;

    public CustomArrayAdapter(Context context) {
        super(context, android.R.layout.simple_list_item_2);
        mInflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }

    public void setData1(ArrayList<FinalData> data) {
        System.out.println("chch");
        clear();
        System.out.println("chch");
        if (data != null) {
            for (FinalData appEntry : data) {
                add(appEntry);
                System.out.println("chch");
            }
        }
    }

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) {
        View view;

        if (convertView == null) {
            view = mInflater.inflate(R.layout.single_item, parent, false);
        } else {
            view = convertView;
        }

        FinalData item = getItem(position);
        if (position % 2 == 0) {
            ((TextView)view.findViewById(R.id.train_info)).setEllipsize(TruncateAt.MARQUEE);
            ((TextView)view.findViewById(R.id.train_info)).setSelected(true);
            ((TextView)view.findViewById(R.id.stations_info)).setEllipsize(TruncateAt.MARQUEE);
            ((TextView)view.findViewById(R.id.stations_info)).setSelected(true);
            ((TextView)view.findViewById(R.id.stations_info)).setText(item.getFullData());
            ((AutoResizeTextView)view.findViewById(R.id.time_info)).setText(item.getShortData());
            ((TextView)view.findViewById(R.id.train_info)).setText(item.getTimeData());

            ((TextView)view.findViewById(R.id.train_info)).setBackgroundColor(Color.parseColor("#6dcaec"));
            ((TextView)view.findViewById(R.id.stations_info)).setBackgroundColor(Color.parseColor("#a8dff4"));
            ((AutoResizeTextView)view.findViewById(R.id.time_info)).setBackgroundColor(Color.parseColor("#6dcaec"));
        } else {
            ((TextView)view.findViewById(R.id.train_info)).setEllipsize(TruncateAt.MARQUEE);
            ((TextView)view.findViewById(R.id.train_info)).setSelected(true);
            ((TextView)view.findViewById(R.id.stations_info)).setEllipsize(TruncateAt.MARQUEE);
            ((TextView)view.findViewById(R.id.stations_info)).setSelected(true);
            ((TextView)view.findViewById(R.id.stations_info)).setText(item.getFullData());
            ((AutoResizeTextView)view.findViewById(R.id.time_info)).setText(item.getShortData());
            ((TextView)view.findViewById(R.id.train_info)).setText(item.getTimeData());

            ((TextView)view.findViewById(R.id.train_info)).setBackgroundColor(Color.parseColor("#cf9fe7"));
            ((TextView)view.findViewById(R.id.stations_info)).setBackgroundColor(Color.parseColor("#ddbcee"));
            ((AutoResizeTextView)view.findViewById(R.id.time_info)).setBackgroundColor(Color.parseColor("#cf9fe7"));
        }
        return view;
    }
}
