在ViewHolder中为classrecyclerView项目折叠设置onclick

public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
    private boolean isExpanded;
    private TextView titleTextView;
    private TextView detailsTextView;

    public ViewHolder(View itemView) {
        super(itemView);
        titleTextView = itemView.findViewById(R.id.titleTextView);
        detailsTextView = itemView.findViewById(R.id.detailsTextView);
        itemView.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        if (isExpanded) {
            // 折叠项目
            isExpanded = false;
            detailsTextView.setVisibility(View.GONE);
        } else {
            // 展开项目
            isExpanded = true;
            detailsTextView.setVisibility(View.VISIBLE);
        }
    }
}
