在android中的片段中设置列表视图适配器

Question

我想要一个自定义行,所以我在xml中使用List View并膨胀成片段.我对如何为列表View设置适配器感到困惑.我创建了一个扩展Base Adapter的新适配器.在getView方法中,我真的不知道在扩展row.xml布局时要传递什么上下文.如何为列表视图设置适配器以及在哪里？

public class ResultsFragment extends Fragment{


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.results_layout, container, false);
        listView = (ListView)v.findViewById(R.id.results);
        return v;
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);


        loadPage(dataBean.getWhat(), dataBean.getWhere(), dataBean.getPageStart());

        //resultsAdapter.setRssData(rssData);
        //setListAdapter(resultsAdapter);
    }

    @Override
    public void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        Context context = getActivity().getApplicationContext();
        resultsAdapter = new ResultsAdapter(context);
    }





    /**
     * Set List Adapter
     */
    private void setAdapter(){
        if(listView.getAdapter() == null){
            listView.setAdapter(resultsAdapter);
        }
        else{
            resultsAdapter.notifyDataSetChanged();
        }
    }


}

Answer 1

您必须扩展Listfragment(而不是Fragment),并使用它ListFragment.setListAdapter来设置适配器.在适配器getView()膨胀你的行..这就是全部

Answer 2

如果您不想更改扩展类,则应使用listview.setAdapter(...)方法.正如你在我的例子中看到的:

ListView productList= (ListView) getActivity().findViewById(R.id.product_list);


    SampleAdapter adapter = new SampleAdapter(getActivity());


    adapter.add(new SampleItem(
            "Sunny LCD TV 2\"  SN022L66-T1 Full HD",
            R.drawable.product_sample_pic);


    productList.setAdapter(adapter);
