获取到数据，却无法显示

我是不是忘了 2018-11-08 07:25:16

我在一个LinearLayout布局里循环插入view，实现图片左右滑动的效果。
思路是：去通过豆瓣api接口获取数据，然后解析JSON数据，把数据得到后，LinearLayout.addview（view）
可是每次运行app，效果都是这样（Fragment之间来回切换也显示不出来）

但是呢，我我点击那个【实时票房】是Fragment跳转activtiy的，跳转activtiy后我再返回【电影】这里，数据就显示出来了...

已经测试过了数据是获取到的

这是代码部分，我直接在Fragment里的onCreateView里面调用 moviceTheaterData();



 //获取《正在热映》的数据

    public void moviceTheaterData() {



        try {

            //获取电影名称

            String str = "https://api.douban.com/v2/movie/in_theaters";

            URL url = new URL(str);

            new MoviceThread(url).start();

        } catch (MalformedURLException e) {

            e.printStackTrace();

        }

    }





    class MoviceThread extends Thread {

        URL myurl;



        public MoviceThread(URL myurl) {

            this.myurl = myurl;

        }



        @Override

        public void run() {

            InputStream in = null;

            try {

                HttpURLConnection conn = (HttpURLConnection) myurl.openConnection();

                conn.setRequestMethod("GET");

                conn.setConnectTimeout(5000);

                conn.setReadTimeout(5000);

                int code = conn.getResponseCode();

                if (code == 200) {

                    in = conn.getInputStream();

                    BufferedReader reader = null;

                    reader = new BufferedReader(new InputStreamReader(in));

                    StringBuilder response = new StringBuilder();

                    String line;

                    while ((line = reader.readLine()) != null)

                        response.append(line);

                    json = response + "";

                    //----------------------------解析数据---------------------------

                        }

                    });

                }

            } catch (IOException e) {
