안드로이드 앱 만들기 list view 에 checkbox 넣어보기

앱을 만들다 보면 listview 혹인 recyclelistview 등을 사용할 일이 있다.  그런데, 그 안에 있는 item 으로 checkbox, button 등을 넣어 화면을 구성해 보면 (focus 가 도달하는 것들) listview 의 item click 이 제어되지 않고 그 안에 있는 checkbox나 button 등이 클릭 되는 현상을 보인다.

 이럴 떄 어떻게 하면 listview 의 item 으로 제어를 옮길 수 있는 것인가에 대한 고민이 생긴다.

구글신에게 물어보고 찾아보는 방법이 있기는 하지만, 그럴 시간이면 간단하게...

 

        <CheckBox
            android:id="@+id/ckSendSeqNo"
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="8"
            android:focusable="false"
            android:clickable="false" />

 

checkbox 나 button 에게 focus가 가지 못하게 false 처리를 해 주는 것이다. click 도 못하게 false 을 해 준다.

그리고 listview 의 setOnItemClickListener 을 이용해서 

데이터 값을 조정해 주고 adapter 에서 checkbox 의 값을 설정해 주는 방식으로 처리를 해본다.

        binding.listSendMessage.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                int iCnt = 0 ;
                for(int i=0; i < beans.size() ;  i++) {
                    if (beans.get(i).isSelectedMsg()) iCnt++;
                }
                if (iCnt > 0) {
                    beans.get(position).setSelectedMsg(false);
                    adapter.notifyDataSetChanged(beans);
                    Toast.makeText(getContext(), iCnt +"개 이상 선택할 수 없습니다.", Toast.LENGTH_SHORT).show();
                    return;
                }
                beans.get(position).setSelectedMsg(!beans.get(position).isSelectedMsg());
                adapter.notifyDataSetChanged(beans);
            }
        });

beans.get(position).setSelectedMsg(false); 이렇게 false 로 하던지 아니면 true 로 설정을 한 다음...

import java.util.ArrayList;

public class MsgSendAdapter extends BaseAdapter {

    DataitemBinding binding ;
    ArrayList<MsgTargetBean> msgTargetBeans ;
    LayoutInflater inflater;
    Context context ;
    int nListCnt ;

    public MsgSendAdapter(ArrayList<MsgTargetBean> odata, Context context) {
        this.msgTargetBeans = odata ;
        this.context = context ;
        this.inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }

    @Override
    public int getCount() {
        return msgTargetBeans.size();
    }

    @Override
    public Object getItem(int position) {
        return msgTargetBeans.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    public void notifyDataSetChanged(ArrayList<MsgTargetBean> odata) {
        this.msgTargetBeans = odata ;
        nListCnt = msgTargetBeans.size();
        this.notifyDataSetChanged();
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        binding = DataitemBinding.inflate(inflater);
        CustomViewHolder holder ;
        if (convertView == null) {
            convertView = binding.getRoot() ;
            holder = new CustomViewHolder();
            holder.ckSendSeqNo = binding.ckSendSeqNo ;
            holder.txtSendMessage = binding.txtSendMessage ;
            holder.txtReceivedPhoneNum = binding.txtReceivedPhoneNum ;
            holder.txtSendTy = binding.txtSendTy ;
            convertView.setTag(holder);
        } else {
            holder = (CustomViewHolder) convertView.getTag();
        }

        holder.ckSendSeqNo.setChecked(msgTargetBeans.get(position).getSelectSend());
        holder.ckSendSeqNo.setText(msgTargetBeans.get(position).getSendSeqNo());
        holder.txtSendMessage.setText(msgTargetBeans.get(position).getSendMessage());
        holder.txtReceivedPhoneNum.setText(msgTargetBeans.get(position).getReceivePhoneNum());
        if ("Y".equals(msgTargetBeans.get(position).getSendTy())) {
            holder.txtSendTy.setText("전송완료");
            holder.txtSendTy.setBackgroundColor(context.getColor(R.color.softBlue));
            holder.txtSendTy.setTextColor(context.getColor(R.color.white));
        } else {
            holder.txtSendTy.setText("");
            holder.txtSendTy.setBackgroundColor(context.getColor(R.color.white));
            holder.txtSendTy.setTextColor(context.getColor(R.color.white));
        }
        return convertView;
    }

    public class CustomViewHolder {
        CheckBox ckSendSeqNo ;
        TextView txtSendTy ;
        TextView txtSendMessage ;
        TextView txtReceivedPhoneNum ;
    }
}

holder.ckSendSeqNo.setChecked(msgTargetBeans.get(position).getSelectSend()); 처럼 실행해 주면 그것으로 끝.
