Android cardview onclick實現

Question

我列出了一張卡片視圖列表，這些視圖序列的時間范圍是從0:00到23:00，間隔為15分鍾，即[0:00，0:15，....，22：45、23：00 ]現在，我想對卡片實施onClick，每當我單擊一張卡片時，卡片中都會有一個復選框，其選中狀態設置為true；當我單擊另一張卡片時，先前單擊的卡片復選框將設置為false，不可見，而新的將包含一個選中的復選框

public class SuggestTimeCardAdapter extends RecyclerView.Adapter<SuggestTimeCardAdapter.ViewHolder> {

    private Context context;

    List<SuggestTimeList> suggestTimeLists;

    public SuggestTimeCardAdapter(List<SuggestTimeList> suggestTimeLists, Context context){
        super();
        this.suggestTimeLists = suggestTimeLists;
        this.context = context;
    }

    @Override
    public SuggestTimeCardAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View v = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.suggest_time_card, parent, false);
        SuggestTimeCardAdapter.ViewHolder viewHolder = new SuggestTimeCardAdapter.ViewHolder(v);
        return viewHolder;
    }

    @Override
    public void onBindViewHolder(final SuggestTimeCardAdapter.ViewHolder holder, int position) {

        SuggestTimeList suggestTimeList =  suggestTimeLists.get(position);

        holder.tvSuggestTime.setText(suggestTimeList.getSuggestTime());

        holder.suggest_time_card_view.setOnClickListener(new View.OnClickListener(){

            @Override
            public void onClick(View v){
                //implement the click
                holder.cbSuggestTime.setVisibility(View.VISIBLE);
                holder.cbSuggestTime.setChecked(true);
            }
        });


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

    class ViewHolder extends RecyclerView.ViewHolder {
        public TextView tvSuggestTime;
        public CheckBox cbSuggestTime;
        public CardView suggest_time_card_view;


        public ViewHolder(View itemView) {
            super(itemView);
            tvSuggestTime = (TextView) itemView.findViewById(R.id.tvSuggestTime);
            cbSuggestTime = (CheckBox) itemView.findViewById(R.id.cbSuggestTime);
            suggest_time_card_view = (CardView) itemView.findViewById(R.id.suggest_time_card_view);


        }
    }
}

現在我遇到的問題是，每當我單擊一張卡（例如0:00）時，都將檢查所有以2:15遞增的卡，以便同時檢查2:15，4:30等。滾動而不單擊任何內容，則選中的卡會突然變為未選中狀態，並且將對隨機卡進行檢查。 我很困惑，有人可以幫忙嗎？

Answer 1

在SuggestTimeList類中，添加一個屬性； isChecked ，像這樣：

class SuggestTimeList
{
   boolean isChecked;
   //// Other attributes and methods...
   public void setChecked(boolean isChecked) {
      this.isChecked = isChecked;
   }

   public boolean isChecked() {
      return isChecked;
   }
}

然后在您的適配器中執行以下操作：

@Override
public void onBindViewHolder(final SuggestTimeCardAdapter.ViewHolder holder, int position) {

    SuggestTimeList suggestTimeList =  suggestTimeLists.get(position);

    holder.tvSuggestTime.setText(suggestTimeList.getSuggestTime());
    if(suggestTimeList.isChecked()) {
            holder.cbSuggestTime.setVisibility(View.VISIBLE);
            holder.cbSuggestTime.setChecked(true);
    }else {
            holder.cbSuggestTime.setChecked(false);
            holder.cbSuggestTime.setVisibility(View.INVISIBLE);
    }  
    holder.suggest_time_card_view.setOnClickListener(new View.OnClickListener(){

        @Override
        public void onClick(View v){
            //implement the click
            holder.cbSuggestTime.setVisibility(View.VISIBLE);
            holder.cbSuggestTime.setChecked(true);
            for(SuggestTimeList s : suggestTimeLists) {
                 s.setChecked(false);
            }
            suggestTimeList.setChecked(true);
            notifyDataSetChanged();

        }
    });


}
