android - 如何在ListView Android中设置所有值

我创建了一个列表视图。从json响应中检索所有值，但列表中仅显示最后一个值。如何在列表视图中显示所有值。

 SixFragment.movieList = new ArrayList<Movie1>();

 for (int i1 = 0; i1 < jsonArray3.length(); i1++) {
     try {
         JSONObject jsonObject = jsonArray3.getJSONObject(i1);
         review_rating = jsonObject.optString("review_rating").toString();
         username_rate = jsonObject.optString("username").toString();
         review_title = jsonObject.optString("review_title").toString();
         review_desc = jsonObject.optString("review_desc").toString();
         sleep = jsonObject.optString("Sleep").toString();
         location = jsonObject.optString("Location").toString();
         service = jsonObject.optString("Service").toString();
         rooms = jsonObject.optString("Rooms").toString();
         cleanliness = jsonObject.optString("Cleanliness").toString();
         userimage1 = jsonObject.optString("user_image").toString();

         Movie1 movie = new Movie1();


                    movie.setRate_userimage(userimage1);
                    movie.setreview_rating(review_rating);
                    movie.setusername_rate(username_rate);
                    movie.setreview_title(review_title);
                    movie.setreview_desc(review_desc);
                    movie.setsleep(sleep);
                    movie.setlocation(location);
                    movie.setservice(service);
                    movie.setraterooms(rooms);
                    movie.setcleanliness(cleanliness);

                    SixFragment.movieList.add(movie);

                } catch (JSONException e) {
                    e.printStackTrace();
                }

            }

这是我的片段页面：

public class SixFragment extends Fragment{
    public static String userimage;
    public static String review_rating;
    public static String username_rate;
    public static String  review_title;
    public static String review_desc;
    public static String  sleep;
    public static String  location;
    public static String  service;
    public static String  rooms;
    public static String  cleanliness;
    public static ArrayList stringArray;
    public static ArrayList<Movie1> movieList= new ArrayList<Movie1>();;

    ListView listView;
    Reviewadapter reviewadapter;

    public SixFragment() {
        // Required empty public constructor
    }

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

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View v= inflater.inflate(R.layout.fragment_six, container, false);
        ListView list=(ListView)v.findViewById(R.id.six_listView);



        return v;
    }

}

此logcat错误`

最佳答案

在您的片段中，使列表静态：

public class SixFragment extends Fragment{

      // Your code
//------------DO THIS------------------///

public static List<Movie1> movieList = new ArrayList<Movie1>();


public SixFragment() {
    // Required empty public constructor
}

//Your code

}

片段中的其余代码将保持不变。

像这样更改您的JSON循环：

SixFragment.movieList = new ArrayList<Movie1>();
    for (int i1 = 0; i1 < jsonArray3.length(); i1++) {
        try {
            JSONObject jsonObject = jsonArray3.getJSONObject(i1);
            review_rating = jsonObject.optString("review_rating").toString();
            username_rate = jsonObject.optString("username").toString();
            review_title = jsonObject.optString("review_title").toString();
            review_desc = jsonObject.optString("review_desc").toString();
            sleep = jsonObject.optString("Sleep").toString();
            location = jsonObject.optString("Location").toString();
            service = jsonObject.optString("Service").toString();
            rooms = jsonObject.optString("Rooms").toString();
            cleanliness = jsonObject.optString("Cleanliness").toString();
            userimage1 = jsonObject.optString("user_image").toString();

            Movie1 movie = new Movie1();


            movie.setRate_userimage(userimage1);
            movie.setreview_rating(review_rating);
            movie.setusername_rate(username_rate);
            movie.setreview_title(review_title);
            movie.setreview_desc(review_desc);
            movie.setsleep(sleep);
            movie.setlocation(location);
            movie.setservice(service);
            movie.setraterooms(rooms);
            movie.setcleanliness(cleanliness);

            SixFragment.movieList.add(movie);

        } catch (JSONException e) {
            e.printStackTrace();
        }

    }
