Question

我正在尝试在片段中显示SQLite数据库中的列表。我已经使用一个活动尝试了它并且它是成功的，但是使用片段我无法使用片段使其工作。

public class AppleFragment extends ListFragment {

    /** An array of items to display in ArrayList */
    String apple_versions[] = new String[]{
        "Mountain Lion",
        "Lion",
        "Snow Leopard",
        "Leopard",
        "Tiger"

    };

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,    Bundle savedInstanceState) {
        /** Creating array adapter to set data in listview */
        ArrayAdapter<String> adapter = new ArrayAdapter<String> (getActivity().getBaseContext(),  android.R.layout.simple_list_item_multiple_choice, apple_versions);

        /** Setting the array adapter to the listview */
        setListAdapter(adapter);

        return super.onCreateView(inflater, container, savedInstanceState);
    }

    @Override
    public void onStart() {
        super.onStart();

        /** Setting the multiselect choice mode for the listview */
        getListView().setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
    }

}

这只是一个例子，我想将其转换为SQLite列表并将其显示在片段中。

Answer 1

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

    ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(),
        android.R.layout.simple_list_item_1, apple_versions);
    setListAdapter(adapter);
  }

不要使用onCreateView，使用片段的onActivityCreated或onViewCreated方法加载列表。
