我想从服务器加载数据，为此我使用$this->load->database(); $this->load->dbutil(); // check connection details if( !$this->dbutil->database_exists('myDatabase')) echo 'Not connected to a database, or database not exists'; 。我想要加载帖子（标题，描述，图片等等）以及我希望从此帖子加载评论的数据。

我可以加载标题，描述，图片等等...并显示它。但我不知道如何在活动中显示帖子评论！

ModelResponse（使用getter和setter）： 

Retrofit

模型（使用getter和setter）： 

public class R_CatModelResponse {

    @SerializedName("status")
    public String Cat_status;
    @SerializedName("count")
    public int Cat_count;
    @SerializedName("pages")
    public int Cat_pages;
    @SerializedName("category")
    public Retrofit_ColoniesModel category;
    @SerializedName("posts")
    public List<R_CatModel> Cat_posts;

PostComment（使用getter和setter）： 

public class R_CatModel {

    @SerializedName("id")
    public Integer id;
    @SerializedName("type")
    public String type;
    @SerializedName("slug")
    public String slug;
    @SerializedName("url")
    public String url;
    @SerializedName("status")
    public String status;
    @SerializedName("title")
    public String title;
    @SerializedName("title_plain")
    public String title_plain;
    @SerializedName("content")
    public String content;
    @SerializedName("excerpt")
    public String excerpt;
    @SerializedName("date")
    public String date;
    @SerializedName("modified")
    public String modified;
    @SerializedName("comment_count")
    public int comment_count;
    @SerializedName("comment_status")
    public String comment_status;
    @SerializedName("thumbnail")
    public String thumbnail;
    @SerializedName("thumbnail_images")
    public R_CatThumbnailImages thumbnail_images;
    @SerializedName("categories")
    public List<R_CatCategory> categories;
    @SerializedName("author")
    public R_CatAuthor catAuthor;
    @SerializedName("comments")
    public List<R_PostComment> comments;

适配器代码（用于加载评论）： 

@SerializedName("id")
public int cmID;
@SerializedName("name")
public String cmName;
@SerializedName("url")
public String cmUrl;
@SerializedName("date")
public String cmDate;
@SerializedName("content")
public String cmContent;
@SerializedName("parent")
public int cmParent;

活动代码： 

public class CommentAdapter2 extends RecyclerView.Adapter<CommentAdapter2.ViewHolder> {

    private List<R_PostComment> mDataSet;
    private Context context;

    public CommentAdapter2(Context context, List<R_PostComment> mDataSet) {
        this.mDataSet = mDataSet;
        this.context = context;
    }

    @Override
    public CommentAdapter2.ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
        View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.comment_layout, viewGroup, false);
        return new ViewHolder(view);
    }

    @Override
    public void onBindViewHolder(CommentAdapter2.ViewHolder viewHolder, int position) {

        viewHolder.comment_name.setText( ??? );
        viewHolder.comment_date.setText( ??? );
        viewHolder.comment_content.setText(Html.fromHtml( ??? ));

    }

    @Override
    public int getItemCount() {
        return mDataSet.size();
    }

    public class ViewHolder extends RecyclerView.ViewHolder {

        private TextView comment_name, comment_content, comment_date;

        public ViewHolder(View view) {
            super(view);

            comment_name = (TextView) itemView.findViewById(R.id.comment_userName_text);
            comment_content = (TextView) itemView.findViewById(R.id.comment_comment_text);
            comment_date = (TextView) itemView.findViewById(R.id.comment_date_text);
        }
    }
}

ApiInterface： 

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.post_show_page);

        bindActivity();

        // Initialize
        favDB = new FavHelper(context);

        //Give Data
        Bundle bundle = getIntent().getExtras();

        if (bundle != null) {
            postID = bundle.getInt("postID");
            title = bundle.getString("title");
            image = bundle.getString("image");
            content = bundle.getString("content");
            dateTime = bundle.getString("dateTime");
            author = bundle.getString("author");
            category = bundle.getString("category");
            categoryID = bundle.getString("categoryID");
        }

        mAppBarLayout.addOnOffsetChangedListener(this);
        // Setup comment RecyclerView
        comment_Recyclerview.setLayoutManager(mLayoutManager);
        comment_Recyclerview.setHasFixedSize(true);

        startAlphaAnimation(mTitle, 0, View.INVISIBLE);

        // Set Data into views
        if (title != null) {
            postShow_title.setText(title);
            postShow_title2.setText(title);
            title_sliding.setText(getResources().getString(R.string.comment_title) + " " + title);
        }
        loadPostProgressDialog.createAndShow(this);
        if (image != null) {
            Glide.with(this)
                    .load(image)
                    .placeholder(R.drawable.post_image)
                    .listener(new RequestListener<String, GlideDrawable>() {
                        @Override
                        public boolean onException(Exception e, String model, Target<GlideDrawable> target, boolean isFirstResource) {
                            return false;
                        }

                        @Override
                        public boolean onResourceReady(GlideDrawable resource, String model, Target<GlideDrawable> target,
                                                       boolean isFromMemoryCache, boolean isFirstResource) {
                            loadPostProgressDialog.dissmis();
                            return false;
                        }

            WebSettings settings = post_content_web.getSettings();
            settings.setDefaultTextEncodingName("utf-8");

            post_content_web.loadData(content, "text/html; charset=utf-8", "utf-8");
        }
        if (dateTime != null) {
            postShow_dateTime.setText(dateTime);

        }
        if (category != null) {

        }

        post_cover.setOnClickListener(new View.OnClickListener() {
            @Override

                                .putExtra("imageCover", image));

                    }

        Retrofit_ApiInterface apiInterface = Retrofit_ApiClient.getClient().create(Retrofit_ApiInterface.class);

        call.enqueue( ??? )

            @Override

JSON链接： [链接] [1]，@GET("?json=get_category_posts") Call<R_CatModelResponse> getCatResponse(@Query("id") Integer id); （id= ?链接结束）我发送 categoryID 以查看此类别讯息！

如何在此帖子中显示帖子的评论？  谢谢所有＆lt; 3

在你的活动课上。当你这样做时：

call.enqueue()

让我们假设你正确地恢复了身体，因为你说你可以加载标题，描述和图像。

所以你可能有类似的东西：

R_CatModelResponse catModelResponse;
call.enqueue(new CallBack<R_CatModelResponse>()
{
        @Override
        public void onResponse(Call<R_CatModelResponse> call, Response<R_CatModelResponse> response)
        {
            catModelResponse = response.body();
        }
}

... 

List<R_CatModel> catPosts = catModelResponse.getCat_posts();
//For whatever index of the posts you're interested in. Take 0 for example:
List<R_PostComment> comments = catPosts.get(0).getCatPosts();

您可以使用“R_CatModel”的getter获取List，然后使用R_CatModel的getter来检索R_PostComment的List。当您获得List注释对象时，将其传递到RecycerView的适配器（CommentAdapter2）。所以你的活动内容如下：

CommentAdapter2 adapter = new CommentAdapter2(this, comments);
comment_Recyclerview.set(adapter);

请注意，由于Retrofit的入队呼叫是异步的，因此您应该在呼叫成功后进行RecyclerView的设置。

试试这段代码：

private void bindData() {
    // Setup Connect
    Retrofit_ApiInterface apiInterface = Retrofit_ApiClient.getClient().create(Retrofit_ApiInterface.class);
    Call<R_PostModelResponse> call = apiInterface.getPostResponse(postID);
    final ProgressDialog progressDialog = new ProgressDialog(context);
    progressDialog.show();
    Log.d("PostID", "Post : " + postID);

    call.enqueue(new Callback<R_PostModelResponse>() {
        @Override
        public void onResponse(Call<R_PostModelResponse> call, Response<R_PostModelResponse> response) {

            if (response.body() != null) {

                models.addAll(response.body().getPost().getComments());
                Log.e("testComment", "" + response.body().getPost().getComment_count());
                mAdaper.notifyDataSetChanged();

                comment_Recyclerview.setAdapter(mAdaper);

                progressDialog.dismiss();

            } else {
                progressDialog.dismiss();
            }
        }

        @Override
        public void onFailure(Call<R_PostModelResponse> call, Throwable t) {
            Toast.makeText(PostShow_page.this, "Failed", Toast.LENGTH_SHORT).show();
            progressDialog.dismiss();
        }
    });
}
