我是android开发的新手.我正在尝试构建一个带有标签的应用程序(通过片段添加).在其中一个片段中,我试图显示一个列表.这个列表已经使用我从ArrayAdapter扩展的ListAdapter填充,并且我重载了getView()方法.这是我的片段

public class tabcontentActivity extends Fragment {

    public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
        if (container == null) {
            return null;
        }
        View v = (LinearLayout) inflater.inflate(R.layout.tablayout, container,
            false);
        ListView lv = (ListView) v.findViewById(R.id.listview1);
        ListViewAdapter adapter = new ListViewAdapter(container.getContext(),
            android.R.layout.simple_list_item_1, R.id.textview1);
        adapter.notifyDataSetChanged();
        lv.setAdapter(adapter);

        return v;
    }
}

这就是我实现ListAdapter的方法

public class ListViewAdapter extends ArrayAdapter {
    Context context1;

    public ListViewAdapter(Context context,int resource, int textViewResourceId) {
        super(context,resource,textViewResourceId);
        this.context1 = context;
        System.out.println("here aswell!!!!!!");
        // TODO Auto-generated constructor stub
    }

    public View getView(int …
