如何将5个不同的字符串设置为ListView的一个项目？

Question

我正在尝试设置5个字符串，airport_finish，date_finish，time_finish，persons_finish，address_finish＆amp; flightnr_finish，在ListView的一个Item中，它与扩展Fragment的Class DemandFragment相关联。

有可能吗？我该怎么做？

现在所有字符串都在不同的项目中。

FinishPostFragment：

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case R.id.add_post_finish:
            // User chose the "Favorite" action, mark the current item
            // as a favorite...
            final FragmentManager fm = getActivity().getFragmentManager();
            final Fragment fragment = new DemandFragment();

            // put strings to listview in DemandFragment
            ParseObject post = new ParseObject("Posts");

            post.put("airport", airport_finish.getText().toString());
            post.put("date", date_finish.getText().toString());
            post.put("time", time_finish.getText().toString());
            post.put("persons", persons_finish.getText().toString());
            post.put("address", address_finish.getText().toString());
            post.put("flightnr", flightnr_finish.getText().toString());

            post.saveInBackground(new SaveCallback() {
                @Override
                public void done(ParseException e) {
                    airport_finish.setText("");
                    date_finish.setText("");
                    time_finish.setText("");
                    persons_finish.setText("");
                    address_finish.setText("");
                    flightnr_finish.setText("");

                    ParseQuery<ParseObject> query = ParseQuery.getQuery("Posts");
                    query.findInBackground(new FindCallback<ParseObject>() {
                        public void done(List<ParseObject> scoreList, ParseException e) {
                            if (e == null) {
                                ArrayList arrayPost = new ArrayList<String>();

                                for (ParseObject j : scoreList) {

                                    arrayPost.add(j.getString("airport"));
                                    arrayPost.add(j.getString("date"));
                                    arrayPost.add(j.getString("time"));
                                    arrayPost.add(j.getString("persons"));
                                    arrayPost.add(j.getString("address"));
                                    arrayPost.add(j.getString("flightnr"));
                                }

                                Bundle bundle = new Bundle();
                                bundle.putStringArrayList("listPost", arrayPost);
                                fragment.setArguments(bundle);
                                fm.beginTransaction().replace(R.id.content_main, fragment).commit();

                            } else {
                                // error
                            }
                        }
                    });
                }
            });

            return true;

DemandFragment：

    public class DemandFragment extends Fragment {

    ListView lv;

    ArrayList yourList;
    ArrayAdapter adapter;

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_demand, container, false);

        if(rootView != null){
            lv = (ListView) rootView.findViewById(R.id.listDemand);

            ArrayList<String> arraypost = getArguments().getStringArrayList("listPost");
            Log.d("arraylist", "arraypost");

            ArrayAdapter adapter = new ArrayAdapter(getActivity(), android.R.layout.simple_list_item_1, arraypost);

            lv.setAdapter(adapter);

            lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                @Override
                public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                    // clicked on item show post

                }
            });
        }

        return rootView;
    }

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

        setHasOptionsMenu(true);

    }

}

您要做的是为您ListView创建自定义项目。

然后你可以用xml：

制作自定义行

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

<TextView android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Header"/>

<TextView 
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/text"/>


</LinearLayout>

看起来像这样：

在您的情况下，您将只有5个textviews ...

您需要扩展BaseAdapter并覆盖某些方法才能使其正常工作。
