recyclerview.onbindviewholder始終處于位置 0public class NoteAdapter extends RecyclerView.Adapter<NoteAdapter.ViewHolder> {    public static final int UNCOMPLETED = 0;    public static final int COMPLETED = 1;    public static final int HIGHTLIGHT = 2;    public static final int HIGHTLIGHT_COMPETED = 3;    Cursor cursor;    Context context;    public NoteAdapter(Context context, Cursor cursor) {        this.context = context;        this.cursor = cursor;    }    public Cursor getCursor() {        return this.cursor;    }    public void setCursor(Cursor cursor) {        this.cursor = cursor;    }    public Context getContext() {        return context;    }    public void setContext(Context context) {        this.context = context;    }    @Override    public int getItemViewType(int position) {        if (cursor.moveToPosition(position)) {            cursor.move(position);            String content = cursor.getString(cursor.getColumnIndex(DatabaseHandler.KEY_CONTENT));            int completed = cursor.getInt(cursor.getColumnIndex(DatabaseHandler.KEY_COMPLETED));            int hightlight = cursor.getInt(cursor.getColumnIndex(DatabaseHandler.KEY_HIGHTLIGHT));            if (completed == 1) {                if (hightlight == 1) {                    return HIGHTLIGHT_COMPETED;                }                return COMPLETED;            }            if (hightlight == 1 && completed == 0) {                return HIGHTLIGHT;            }            return UNCOMPLETED;        }        return -1;    }該程序不包含任何錯誤。當我運行程序時，它總是只顯示0位置的元素，其余位置不顯示。函數getItemCount正常工作，返回 20 個元素。英語不是我的母語，很抱歉有任何語法錯誤。感謝大家。
