请在这里 – dipali

发表您的适配器代码，你在一个时间显示六个项目？ – muratgu

这是循环view..you需要维护 –

尝试这种方式。这个工作对我来说

public class CustomAdapter extends BaseAdapter { 
    private final LayoutInflater inflater; 
    private final Context context; 
    private List<ModelPooja> listData; 

    public CustomAdapter(Context mainActivity, List<ModelPooja> listData) { 
     context = mainActivity; 
     this.listData = listData; 
     inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    } 

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

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

    @Override 
    public long getItemId(int position) { 
     return 0; 
    } 

    @Override 
    public View getView(final int position, View convertView, ViewGroup parent) { 
     final ViewHolder holder; 

     if (convertView == null) { 
      holder = new ViewHolder(); 
      convertView = inflater.inflate(R.layout.list_item_poojaselection, null); 
      holder.tv = (TextView) convertView.findViewById(R.id.list_item_poojaname); 
      holder.checks = (CheckBox) convertView.findViewById(R.id.list_item_poojacheck); 
      convertView.setTag(holder); 
     }else { 
      holder = (ViewHolder) convertView.getTag(); 
     } 
     holder.checks.setOnCheckedChangeListener(null); 
     holder.checks.setFocusable(false); 

     if (listData.get(position).isselected) { 
      holder.checks.setChecked(true); 
     } else { 
      holder.checks.setChecked(false); 
     } 

     holder.checks.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { 
      @Override 
      public void onCheckedChanged(CompoundButton cb, boolean b) { 

       if (checkMaxLimit()) { 

        if (listData.get(position).isselected && b) { 
         holder.checks.setChecked(false); 
         listData.get(position).isselected = false; 

        } else { 
         holder.checks.setChecked(false); 
         listData.get(position).isselected = false; 
         Toast.makeText(context, "Max limit reached", Toast.LENGTH_SHORT).show(); 
        } 
       } else { 
        if (b) { 
         listData.get(position).isselected = true; 
        } else { 
         listData.get(position).isselected = false; 
        } 
       } 
      } 
     }); 

     holder.tv.setText(listData.get(position).getPOOJA_LISTING_NAME()); 
     return convertView; 
    } 

    public boolean checkMaxLimit() { 
     int countermax = 0; 
     for(ModelPooja item : listData){ 
      if(item.isselected){ 
       countermax++; 
      } 
     } 
     return countermax >= 5; 
    } 

    public class ViewHolder { 
     TextView tv; 
     public CheckBox checks; 
    } 
}

对于Recyclerview尝试这种方式
