Question

现在我正在从tmdb APi获取电影。

我想从他们的终端获得评论。 http://docs.themoviedb.apiary.io/#reference/movies/movieidreviews/get?console=1

现在我正在从Maintrctivity中将Retrofit的电影转到我的recycleview。我有三个模型类和接口。

我不知道如何为审核列表创建适配器。在我创建Adapter之后，我需要在我的DetailsActivity中调用它有人可以帮帮我吗？

我收到错误： public int getItemCount（）

这是我的项目github：https://github.com/adnxy/MyMovieApp

这是我的模型类，我不会在这里写getter和setter：

public class Reviews {
    @SerializedName("id_review")
    private int id;
    @SerializedName("author_review")
    private String author;
    @SerializedName("content_review")
    private String content;
    @SerializedName("url_review")
    private String url;

审查结果模型类如下：

public class ReviewResult {

private List<Reviews> reviewResults;

public List<Reviews> getReviewResults() {

    return reviewResults;
}

ReviewWraper没有getter和setter吼叫：

public class ReviewWraper {

@SerializedName("id")
private int id;
@SerializedName("page")
private int page;
@SerializedName("results")
private List<Reviews> results;

Bellow是我的AdapterClass。这就是我想要做的，但它不起作用。我收到错误： public int getItemCount（）

public class ReviewAdapter {


private List<Reviews> rReviewList;
private LayoutInflater rInflater;
private Context rContext;

public ReviewAdapter(Context context, List<Reviews> rReviewList) {
    this.rContext = context;
    this.rReviewList = rReviewList;
    this.rInflater = LayoutInflater.from(context);
}

public MovieDetailActivity.MovieViewHolder onCreateViewHolder(ViewGroup parent, final int viewType) {

    View view = rInflater.inflate(R.layout.row_review, parent, false);




public void onBindViewHolder(MovieDetailActivity.MovieViewHolder holder, int position) {

            Reviews reviews = rReviewList.get(position);
            Picasso.with(rContext)
                    .load(reviews.getUrl())
                    .resize(342, 0)
                    .into(holder.imageView);
        }




        @Override
        public int getItemCount() {
            return (rReviewList == null) ? 0 : rReviewList.size();
        }

        public void setReviewList (List<Reviews> reviewsList) {
            this.rReviewList = new ArrayList<>();
            this.rReviewList.addAll(reviewsList);

            notifyDataSetChanged();

        }

        private void notifyDataSetChanged() {

        }

}

在ReviewAdapter课程中：

public class ReviewAdapter extends RecyclerView.Adapter<MainActivity.MovieViewHolder> {

private List<Reviews> rReviewList;
private LayoutInflater rInflater;
private Context rContext;

public ReviewAdapter(Context context, List<Reviews> rReviewList) {
    this.rReviewList = rReviewList;
    this.rContext = context;
    this.rInflater = LayoutInflater.from(context);
}

public MainActivity.MovieViewHolder onCreateViewHolder(ViewGroup parent, final int viewType) {
    // create a new view
    View view = rInflater.inflate(R.layout.row_review, parent, false);
    return new MainActivity.MovieViewHolder(view);
}

@Override
public void onBindViewHolder(MainActivity.MovieViewHolder holder, int position) {
    Reviews reviews = rReviewList.get(position);
    Picasso.with(rContext)
            .load(reviews.getUrl())
            .resize(342, 0)
            .into(holder.imageView);
    holder.itemView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            //Perform click
        }
    });
}


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

//To update data
public void setReviewList(List<Reviews> reviewsList) {
    this.rReviewList = new ArrayList<>();
    this.rReviewList.addAll(reviewsList);
    notifyDataSetChanged();
}

}

需要为我从Api获取的List创建适配器
