有人知道我的版式有什么问题吗？我无法弄清楚为什么ListView只显示一项.

我正在使用“片段活动”和SimpleCusrsorAdapter将项目填充到我的ListView中.如果是,这是我的课；

public class ActivityHome extends Fragment {
    CardView cardViewWordOfTheDay;
    private WordsDbAdapter dbHelper;
    private SimpleCursorAdapter dataAdapter;
    private String wordFromSpinner = "ALL";
    ListView listView;
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        final View view =  inflater.inflate(R.layout.layout, container, false);

        Button btnCloseWordOfTheDay = (Button) view.findViewById(R.id.btnCloseWordOfTheDay);
        listView = (ListView) view.findViewById(R.id.words_list_view);

        btnCloseWordOfTheDay.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                cardViewWordOfTheDay = (CardView) view.findViewById(R.id.card_view);
                cardViewWordOfTheDay.setVisibility(View.GONE);

            }
        });


        dbHelper = new WordsDbAdapter(getActivity().getApplicationContext());
        dbHelper.open();
        displayListView(wordFromSpinner);
    return view;
    }

    private void displayListView(String wordFromSpinnerData) {
        Cursor cursor = null;
        try {
            cursor = dbHelper.fetchAllWords(wordFromSpinnerData);
        } catch (Exception e) {
            Toast.makeText(getActivity().getApplicationContext(), "EER " + e, Toast.LENGTH_LONG).show();
        }
        String[] columns = new String[]{
                WordsDbAdapter.KEY_ONE, WordsDbAdapter.KEY_TWO,
                WordsDbAdapter.KEY_THREE, WordsDbAdapter.KEY_FOUR, WordsDbAdapter.KEY_FIVE
        };
        int[] to = new int[]{
                R.id.thisWord, R.id.thisSub, R.id.thisWordFrom, R.id.thisWordLocation, R.id.thisLetter
        };
        dataAdapter = new SimpleCursorAdapter(getActivity().getApplicationContext(), R.layout.words_list_item, cursor, columns, to, 0);
        listView.setAdapter(dataAdapter);

    }

}

我很混乱.我不会发生什么.当我尝试将RelativeLayout的高度更改为500dp时,listView显示其他项目,但不是全部.所以我认为我需要将它设为wrap_parent,但这并不能给我预期的输出.

任何帮助,将不胜感激.非常感谢你！！！

解决方法:

如here所述,

您可以在listView.setAdapter(dataAdapter);之后调用此方法.

public static void setListViewHeightBasedOnChildren(ListView listView) {
    ListAdapter listAdapter = listView.getAdapter();
    if (listAdapter == null)
        return;

    int desiredWidth = View.MeasureSpec.makeMeasureSpec(
            listView.getWidth(), View.MeasureSpec.UNSPECIFIED);
    int totalHeight = 0;

    View view = null;

    for (int i = 0; i < listAdapter.getCount(); i++) {
        view = listAdapter.getView(i, view, listView);
        if (i == 0)
            view.setLayoutParams(new ViewGroup.LayoutParams(
                    desiredWidth, LayoutParams.WRAP_CONTENT));

        view.measure(desiredWidth, View.MeasureSpec.UNSPECIFIED);
        totalHeight += view.getMeasuredHeight();
    }
    ViewGroup.LayoutParams params = listView.getLayoutParams();
    params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
    listView.setLayoutParams(params);
}
