如何在2个片段之间传递JSON数据?

我正在按如下方式检索我的JSON:  myResponse.java:

  public List<Repo> getData() {
        return data;
    }

    public void setData(List<Repo> data) {
        this.data = data;
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (!(o instanceof MyResponse)) return false;

        MyResponse that = (MyResponse) o;

        return data != null ? data.equals(that.data) : that.data == null;

    }

    @Override
    public int hashCode() {
        int result = statusCode.hashCode();
        result = 31 * result + message.hashCode();
        result = 31 * result + (data != null ? data.hashCode() : 0);
        return result;
    }

    public static class Repo {


        @Expose
        @SerializedName("title")
        private String title;



        public String getTitle() {
            return title;
        }

        public void setTitle(String title) {
            this.title = title;
        }

        public String getDescription() {
            return description;
        }

        public void setDescription(String description) {
            this.description = description;
        }

        @Override
        public boolean equals(Object o) {
            if (this == o) return true;
            if (!(o instanceof Repo)) return false;

            Repo repo = (Repo) o;

            if (!id.equals(repo.id)) return false;
            if (!title.equals(repo.title)) return false;
            return description.equals(repo.description);

        }

        @Override
        public int hashCode() {
            int result = id.hashCode();
            result = 31 * result + title.hashCode();
            return result;
        }
    }

现在在我的片段1适配器中:

 itemView.setOnClickListener(v -> {
                AppCompatActivity activity = (AppCompatActivity) itemView.getContext();
                activity.getSupportFragmentManager()
                        .beginTransaction()
                        .disallowAddToBackStack()
                        .setCustomAnimations(R.anim.slide_left, R.anim.slide_right)
                        .add(R.id.root_view, Fragment2.newInstance(), Fragment2.TAG)
                        .commit();

这是我的fragment2新实例:

 public static Fragment2 newInstance() {
        Bundle args = new Bundle();
        Fragment2 fragment = new Fragment2();
        fragment.setArguments(args);
        return fragment;
    }

有没有办法将我从JSON检索的属性标题和描述从片段1传递到片段2? 我想在fragment2文本视图中显示这些属性,但不确定哪种方法最好。尝试过在线查看,但到目前为止还没有运气。有什么想法吗?

在创建新的Player John = new Player(); System.out.println(John); 时,您希望通过Fragment传递数据。

Bundle

然后在您的public static Fragment2 newInstance(Repo repo) { Fragment2 fragment = new Fragment2(); Bundle args = new Bundle(); args.putString("title", repo.getTitle()); args.putString("description", repo.getDescription()); fragment.setArguments(args); return fragment; } 中,您可以再次获取它们。
