RecyclerView clickListener不工作

Question

我已经使用最佳实践实现了recyclerView点击监听器，但它仍然不起作用。回收视图正在使用改造从互联网上加载数据，应该带用户到文章发布的站点，以下是我的代码：

注意:我的RecyclerView是卡视图的RecyclerView

RecyclerView适配器

    public class NewsArticleAdapter extends RecyclerView.Adapter<NewsArticleAdapter.Viewholder> {
    private ArrayList<Article> newsArticles = new ArrayList<>();
    private Context context;
    private OnArticleListener onArticleListener;

    public NewsArticleAdapter(List<Article> newsArticles, Context context, OnArticleListener onArticleListener) {
        this.newsArticles = (ArrayList<Article>) newsArticles;
        this.context = context;
        this.onArticleListener = onArticleListener;
    }

    @NonNull
    @Override
    public Viewholder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.news_list_item, parent, false);
        Viewholder viewholder = new Viewholder(view, onArticleListener);
        return viewholder;
    }

    @Override
    public void onBindViewHolder(@NonNull Viewholder holder, int position) {
        Article currentArticle = newsArticles.get(position);

        holder.newsHeadline.setText(currentArticle.getTitle());
        Glide.with(context)
                .load(currentArticle.getUrlToImage())
                .placeholder(R.drawable.ic_launcher_foreground)
                .into(holder.newsImage);
        holder.newsContent.setText(currentArticle.getContent());
//        holder.publishedTime.setText(UTCtoLocalDateConverter(currentArticle.getPublishedAt()));


    }

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

    public class Viewholder extends RecyclerView.ViewHolder implements View.OnClickListener {
        OnArticleListener onArticleClickedListner;
        TextView newsHeadline;
        TextView newsContent;
        //       TextView publishedTime;
        ImageView newsImage;
        ConstraintLayout parentLayout;

        public Viewholder(@NonNull View itemView, OnArticleListener onArticleListener) {
            super(itemView);
            newsHeadline = itemView.findViewById(R.id.news_headline_textView);
            newsContent = itemView.findViewById(R.id.news_content_textView);
//            publishedTime = itemView.findViewById(R.id.published_time_textView);
            newsImage = itemView.findViewById(R.id.news_image_view);
            parentLayout = itemView.findViewById(R.id.list_item_parent_layout);
            onArticleClickedListner = onArticleListener;
            itemView.setOnClickListener(this);
        }

        @Override
        public void onClick(View view) {
            Log.d("RecyclerViewAdapter", "item position clicked: " + getAdapterPosition());
            onArticleClickedListner.onArticleClicked(getAdapterPosition());
        }
    }

    /*RecyclerView onItemClickListenerInterface*/
    public interface OnArticleListener {
        void onArticleClicked(int position);

    }

}

MainActivity (房屋RecyclerView)

public class MainActivity extends AppCompatActivity implements NewsArticleAdapter.OnArticleListener {
private RecyclerView newsRecyclerView;
private NewsArticleAdapter newsAdapter;
private NewsAPI NewsAPI;
private ArrayList<Article> newsArticles;



@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    newsRecyclerView = findViewById(R.id.newsRecyclerView);
    newsAdapter = new NewsArticleAdapter(new ArrayList<Article>(), this, this);
    RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(this);
    newsRecyclerView.setLayoutManager(layoutManager);
    newsRecyclerView.setAdapter(newsAdapter);


    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(RetrofitClient.BASE_URL)
            .addConverterFactory(GsonConverterFactory.create())
            .build();

    NewsAPI = retrofit.create(NewsAPI.class);

    Call<Example> call = NewsAPI.getRootJSONObject();

    call.enqueue(new Callback<Example>() {
        @Override
        public void onResponse(Call<Example> call, Response<Example> response) {
            if (response.isSuccessful()) {
                newsArticles = (ArrayList<Article>) response.body().getArticles();
                refreshAdapterWithNewsArticles(newsArticles);
            } else {
                Log.d("MainActivity", "Error in on Response " + String.valueOf(response.code()));
            }
        }

        @Override
        public void onFailure(Call<Example> call, Throwable t) {
            Toast.makeText(MainActivity.this, "Error retrieving News Articles :(", Toast.LENGTH_SHORT).show();
        }
    });


}
/*
 *Method used to generate list of data using recyclerView with costom adapter
 *  */
private void refreshAdapterWithNewsArticles(List<Article> body) {
    newsAdapter = null;
    newsAdapter = new NewsArticleAdapter(body, this, MainActivity.this);
    newsRecyclerView.setAdapter(newsAdapter);

}

@Override
public void onArticleClicked(int position) {
    Log.d("MainActivity", "onArticleClicked Was called in MainACtivity");
    Article currentArticle = newsArticles.get(position);
    Uri articleUri = Uri.parse(currentArticle.getUrl());
    Intent intent = new Intent(Intent.ACTION_VIEW, articleUri);
    startActivity(intent);
}

}

受this answer从Jacob Tabak提供的代码的启发，在onCreate方法下的mainActivity中。

recyclerView.addOnItemTouchListener(new RecyclerItemClickListener(MainActivity.this, recyclerView, new RecyclerItemClickListener.OnItemClickListener() {
        @Override
        public void onItemClick(View view, int position) {
            //whatever you want to do with position
        }

        @Override
        public void onLongItemClick(View view, int position) {
            //whatever you want to do with position
        }
    }));

并创建一个新的类名为RecyclerItemClickListener并粘贴到

public class RecyclerItemClickListener implements RecyclerView.OnItemTouchListener {
GestureDetector mGestureDetector;
private OnItemClickListener mListener;

public RecyclerItemClickListener(Context context, final RecyclerView recyclerView, OnItemClickListener listener) {
    mListener = listener;
    mGestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {
        @Override
        public boolean onSingleTapUp(MotionEvent e) {
            return true;
        }

        @Override
        public void onLongPress(MotionEvent e) {
            View child = recyclerView.findChildViewUnder(e.getX(), e.getY());
            if (child != null && mListener != null) {
                mListener.onLongItemClick(child, recyclerView.getChildAdapterPosition(child));
            }
        }
    });
}

@Override
public boolean onInterceptTouchEvent(RecyclerView view, MotionEvent e) {
    View childView = view.findChildViewUnder(e.getX(), e.getY());
    if (childView != null && mListener != null && mGestureDetector.onTouchEvent(e)) {
        mListener.onItemClick(childView, view.getChildAdapterPosition(childView));
        return true;
    }
    return false;
}

@Override
public void onTouchEvent(RecyclerView view, MotionEvent motionEvent) {
}

@Override
public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {
}

public interface OnItemClickListener {
    public void onItemClick(View view, int position);

    public void onLongItemClick(View view, int position);
}}

这是一个定制的RecyclerItemClickListener。

Answer 2

为什么不试试onBindViewHolder()方法中的侦听器呢？

holder.your_layout_item.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            onArticleClickedListner.onArticleClicked(position);
        }
    });

如果你有任何混淆，我可以解释得更清楚。如果你解决了它，你就能接受答案。
