列表視圖升序排列在Android的

Question

我在這個項目上工作，但我不知道我怎麼可以顯示相反的列表視圖（升序）

Artistlist類

public class Artistlist extends ArrayAdapter<Artist> { 

private Activity context; 
private List<Artist> artistList; 

public Artistlist(Activity context,List<Artist> artistList){ 
    super(context,R.layout.list_layout , artistList); 

    this.context = context; 
    this.artistList = artistList; 


} 

@NonNull 
@Override 
public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) { 
    LayoutInflater inflater = context.getLayoutInflater(); 

    View listViewItem = inflater.inflate(R.layout.list_layout,null,true); 

    TextView textViewname = (TextView) listViewItem.findViewById(R.id.textView); 
    TextView textViewGener = (TextView) listViewItem.findViewById(R.id.textView2); 

    Artist artist = artistList.get(position); 

    textViewname.setText(artist.getArtistName()); 
    textViewGener.setText(artist.getArtistGener()); 

    return listViewItem; 
} 

}

如何是否可以反向顯示列表視圖（升序） 謝謝

在將列表發送到適配器之前，請使用以下代碼行

Collections.reverse(artistList);
