如何设置两个适配器插入一个列表？

问题描述

我在android系统工作。我创建一个音乐应用程序。在这个应用程序，我想展示的艺术家的歌曲和名称的标题到列表中。
    这是我的code： -

I am working in android. I am creating a music application. in this application i want to show title of song and name of artist into list. this is my code :-

 String[] title_of_song={"title1","title2","title3","title4","title5"};
 String[] artist_of_song={"artist1","artist2","artist3","artist4","artist5"};
 ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.row_button, R.id.TextView_songName, title_of_song);


 ArrayAdapter<String> adapter1 = new ArrayAdapter<String>(this, R.layout.row_button, R.id.TextView_byArtist, artist_of_song);

 list.setAdapter(adapter);
 list.setAdapter(adapter1); //**this is creating error**

这是创建问题名单无法setAdapter两次。所以请告诉我解决它，所以我可以将 setAdapter 作为歌曲及歌手名称的两个称号。

感谢您提前。

推荐答案

我不知道什么是你想要的目的。无论你的适配器具有相同的codeS。为什么不创建一个具有两个适配器的值的单个适配器。

I do not know what are you trying to achieve. both your adapters have identical codes. why not create a single adapter that has values of both adapters.

刚才看到您的编辑问题

创建定制适配器和膨胀具有两个textviews的布局。 - 一个用于艺术家和一个用于歌曲

create a custom adapter and inflate a layout which has two textviews - one for artist and one for the song.

class TaskAdapter extends ArrayAdapter{

    ArrayList artist, song;
    public TaskAdapter(ArrayList songs, ArrayList artist){
           this.artist = artist;
           this.song = songs;
    }


    public TaskAdapter(Context context, int textViewResourceId ) {
        super(context, textViewResourceId);

    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {

        View v = convertView;
        ViewHolder holder;
        if(v == null) {
            LayoutInflater li = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            v = li.inflate(R.layout.custom_list, null);
            holder = new ViewHolder();
            holder.taskId = (TextView)v.findViewById(R.id....);
            holder.taskDesc = (TextView)v.findViewById(R.id....);

            v.setTag(holder);
        }
        else{
            holder = (ViewHolder)v.getTag();
        }

        holder.tArtist.setText(artist.get(position));

        holder.tSong.setText(song.get(position));


        return v;
    }

}
static class ViewHolder {
    TextView tArtist;
    TextView tSong;

}
