您没有初始化topratedmoviejson[]topratedmoviejson；这就是您在以下位置获得npe的原因

java.lang.NullPointerException: storage == null at java.util.Arrays$ArrayList.(Arrays.java:38) at java.util.Arrays.asList(Arrays.java:155) at com.example.romi.parcelablecreatortest.MainActivityFragment.onCreate(MainActivityFragment.java:74)

在MainActivityFragment中更新

 public void jsonParser(String json) {

        final String LOG_TAG = MainActivityFragment.class.getSimpleName();

        // The variables that we want from the json file
        final String title = "original_title"; // JSONObject
        final String posterPath = "poster_path"; // JSONObject
        final String synopsis = "overview"; // JSONObject
        final String userRating = "popularity"; // JSONObject
        final String releaseDate = "release_date"; // JSONObject

        // Parsing the json file
        try {
            JSONArray jsonArray = new JSONArray(json);
            // for is used to cycle through the json array.
            topRatedMovieJson= new TopRatedMovieJson[jsonArray.length()];
            for (int i = 0; i < jsonArray.length(); i++) {
                JSONObject jsonObject = jsonArray.getJSONObject(i); // getJSONObject(i) will take onw of the json array with i=0 as its first index
                topRatedMovieJson[i] = new TopRatedMovieJson(
                        jsonObject.getString(title),
                        jsonObject.getString(posterPath),
                        jsonObject.getString(synopsis),
                        jsonObject.getString(userRating),
                        jsonObject.getString(releaseDate)
                );
            }
        } catch (JSONException e) {
            e.printStackTrace();
        }
    }
