我有一个多个复选框，但我只想在活动中保存单个复选框值[关闭]

Question

这是我的代码：

public class ImageAdapter extends BaseAdapter 
   {
      private LayoutInflater mInflater;
      private Context mContext;
      public ImageAdapter(Context context) 
      {
           mContext = context;
      }
      public int getCount() 
      {
           return count;
      }
      public Object getItem(int position) 
      {
           return position;
      }
      public long getItemId(int position) 
      {
           return position;
      }
      public View getView(final int position, View convertView, ViewGroup parent) 
      {
           final ViewHolder holder;
           if (convertView == null) 
           {    
                convertView = LayoutInflater.from(mContext).inflate(R.layout.state_info, null); 

                holder = new ViewHolder();                                      
                holder.textview = (TextView) convertView.findViewById(R.id.thumbImage);                                              
                holder.checkbox = (CheckBox) convertView.findViewById(R.id.itemCheckBox); 

                convertView.setTag(holder);

           } 
           else 
           {    
                holder = (ViewHolder) convertView.getTag();
           }          

           convertView.setTag(holder);

           //holder.checkbox.setId(position);
           holder.textview.setId(position);

           holder.checkbox.setId(position);
           holder.checkbox.setOnClickListener(new OnClickListener() {
               @Override
               public void onClick(View v) 
               {           
                   for (int i = 0; i < count; i++) 
                   {       
                       if (v.getId() == i) 
                       {   
                           thumbnailsselection[i] = true;
                           Log.v("check", ""+position);

                       }   
                       else 
                       {   
                           thumbnailsselection[i] = false;
                       }   
                   }
                   notifyDataSetChanged();
               }
           });

           if (thumbnailsselection[position]) 
           {
               holder.checkbox.setChecked(true);
           } 
           else 
           {
               holder.checkbox.setChecked(false);
           }

           holder.textview.setText(items.get(position).getName());

           holder.checkbox.setChecked(thumbnailsselection[position]);
           holder.id = position;
           return convertView;

      }          

 }

当复选框被选中时，您希望在您的类中实现 on check chnge listener 添加字符串中的值或任何您想要取消选中的位置，只需将其删除 当您返回视图时，您想首先检查值如果匹配，则选中该位置的复选框这可能会对您有所帮助

OnCheckedChangeListener Check_Boxes_Listener = new OnCheckedChangeListener() {

    @Override
    public void onCheckedChanged(CompoundButton buttonView,
            boolean isChecked) {

        CheckBox cb = (CheckBox) buttonView;

        if (cb.isChecked() == true) {

            if (Maximum_Selected_Check_Boxes < 16) {
                Maximum_Selected_Check_Boxes++;
                HashMap<String, String> Index = new HashMap<String, String>();
                Index.put("Index", cb.getTag().toString());
                selectCBs.add(Index);

            }

            else

            if (Maximum_Selected_Check_Boxes >= 16) {

                Toast.makeText(Check_Boxes,
                        "You have selected the Maximum Items",
                        Toast.LENGTH_SHORT).show();
                cb.setChecked(false);

            }

        } else if (cb.isChecked() == false) {
            Maximum_Selected_Check_Boxes--;

            String Uncheck = cb.getTag().toString();

            int j = 0;
            for (int i = 0; i < selectCBs.size(); i++) {
                if (Uncheck.equalsIgnoreCase(selectCBs.get(i).get("Index")
                        .toString())) {
                    j = i;
                    selectCBs.remove(j);
                    try {
                        Array_of_Update_Query.remove(j);
                    } catch (IndexOutOfBoundsException e) {

                    }

                }

            }

        }

    }

};

check.setOnCheckedChangeListener(Check_Boxes_Listener);

这是我正在运行的项目中使用的方法的示例，可能会对您有所帮助
