1. 确保已经获取了读取外部存储器权限。

2. 创建一个类来包含音频文件的相关信息。

public class AudioModel {
    private String title;
    private String artist;
    private String duration;
    private String path;

    public AudioModel(String title, String artist, String duration, String path) {
        this.title = title;
        this.artist = artist;
        this.duration = duration;
        this.path = path;
    }

    public String getTitle() {
        return title;
    }

    public String getArtist() {
        return artist;
    }

    public String getDuration() {
        return duration;
    }

    public String getPath() {
        return path;
    }
}

3. 创建一个适配器类来展示列表。

public class AudioListAdapter extends RecyclerView.Adapter {
    private Context context;
    private List audioList;
    private OnItemClickListener onItemClickListener;

    public AudioListAdapter(Context context, List audioList) {
        this.context = context;
        this.audioList = audioList;
    }

    public interface OnItemClickListener {
        void onItemClick(AudioModel audioModel);
    }

    public void setOnItemClickListener(OnItemClickListener listener) {
        this.onItemClickListener = listener;
    }

    @NonNull
    @Override
    public AudioItemViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(context).inflate(R.layout.item_audio, parent, false);
        return new AudioItemViewHolder(view);
    }

    @Override
    public void onBindViewHolder(@NonNull AudioItemViewHolder holder, int position) {
        final AudioModel audio = audioList.get(position);
        holder.title.setText(audio.getTitle());
        holder.artist.setText(audio.getArtist());
        holder.duration.setText(audio.getDuration());
        holder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (onItemClickListener != null) {
                    onItemClickListener.onItemClick(audio);
                }
            }
        });
    }

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

    static class AudioItemViewHolder extends RecyclerView.ViewHolder {
        TextView title;
        TextView artist;
        TextView
