OnClick 用于片段中的 2/3 回收器视图（其本身托管/放置在另一个片段上）不起作用

Question

我在一个片段中有三个回收器视图（它本身托管/放置在另一个片段上），第二个和第三个片段的 onClick 不起作用（第一个工作得很好），我尝试了一切......在这里是我的代码：

第二个 Recycler View 适配器类： 最近的歌曲适配器.java

    package com.myapp.beatify;
    
    import android.view.LayoutInflater;
    import android.view.View;
    import android.view.ViewGroup;
    import android.widget.ImageView;
    import android.widget.TextView;
    
    import androidx.annotation.NonNull;
    import androidx.recyclerview.widget.RecyclerView;
    
    import com.bumptech.glide.Glide;
    
    import java.util.List;
    
    public class RecentSongsAdapter extends RecyclerView.Adapter<RecentSongsAdapter.MyViewHolder> {
        private List<CreateSong> mRecentSongList;
        private OnItemClickListener mListener;
    
        public interface OnItemClickListener {
            void onItemClick(int position);
        }
    
        public void setOnItemClickListener(OnItemClickListener listener) {
            mListener = listener;
        }
    
        public RecentSongsAdapter(List<CreateSong> mRecentSongList) {
            this.mRecentSongList = mRecentSongList;
        }
    
        @NonNull
        @Override
        public MyViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
            View view;
            view = LayoutInflater.from(parent.getContext()).inflate(R.layout.create_recent_songs, parent, false);
            MyViewHolder myViewHolder = new MyViewHolder(view, mListener);
            return myViewHolder;
        }
    
        @Override
        public void onBindViewHolder(@NonNull MyViewHolder holder, int position) {
            Glide.with(holder.imageView.getContext()).load(mRecentSongList.get(position).getImgURL()).into(holder.imageView);
            holder.textView.setText(mRecentSongList.get(position).getTxt());
        }
    
        @Override
        public int getItemCount() {
            return mRecentSongList.size();
        }
    
        public static class MyViewHolder extends RecyclerView.ViewHolder {
            public ImageView imageView;
            public TextView textView;
    
            public MyViewHolder(@NonNull View itemView, final OnItemClickListener listener) {
                super(itemView);
                this.imageView = itemView.findViewById(R.id.recent_img);
                this.textView = itemView.findViewById(R.id.recent_txt);
    
                itemView.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
                        if (listener != null) {
                            int position = getAdapterPosition();
    
                            if (position == RecyclerView.NO_POSITION) {
                                listener.onItemClick(position);
                            }
                        }
                    }
                });
            }
        }
    
    }

    private OnItemClickListener mListener;

    public interface OnItemClickListener {
        void onItemClick(int position);
    }

    public void setOnItemClickListener(OnItemClickListener listener) {
        mListener = listener;
    }

    public OurPicksAdapter(List<CreateSong> mSongList) {
        this.mOurPicksList = mSongList;
    }

    @NonNull

        View view;
        view = LayoutInflater.from(parent.getContext()).inflate(R.layout.create_our_picks, parent, false);

    public static class MyViewHolder extends RecyclerView.ViewHolder {
        public ImageView imageView;
        public TextView textView;

        public MyViewHolder(@NonNull View itemView, final OnItemClickListener listener) {
            super(itemView);
            this.imageView = itemView.findViewById(R.id.our_img);
            this.textView = itemView.findViewById(R.id.our_txt);

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

                    if (listener != null) {
                        int position = getAdapterPosition();

                        if (position == RecyclerView.NO_POSITION) {
                            listener.onItemClick(position);
                        }
                    }

Answer 1

我看了一下https://www.codepile.net/pile/rG8PR0GW，也许您应该将oAdapter.setOnItemClickListener 调用移到ourRecyclerView.setAdapter 之前。

像这样：

    private void createUserRecentRecyclerView() {
        recentRecyclerView = view.findViewById(R.id.user_recent_RV);
        recentRecyclerView.setHasFixedSize(true);

        rAdapter = new RecentSongsAdapter(recentList);
        rAdapter.setOnItemClickListener(
                new RecentSongsAdapter.OnItemClickListener() {
                    @Override
                    public void onItemClick(int position) {
                        Log.e("Info", "Connected");
                        Toast.makeText(getActivity(), "" + position, Toast.LENGTH_SHORT).show();
                    }
                });

        recentRecyclerView.setLayoutManager(new LinearLayoutManager(getActivity(), LinearLayoutManager.HORIZONTAL, false));
        recentRecyclerView.setAdapter(rAdapter);
    }
