    此方法主要是通过实体类,进行赋值取值来判断 是否选中取消CheckBox

    在实体类中定义isChoosed (初始值false 未选中)

    public class ShopGoodsSelectBean {
    private int shopId;
    private int position;
    private boolean isChoosed;
    
    public ShopGoodsSelectBean(int shopId, int position) {
        this.shopId = shopId;
        this.position = position;
    }
    
    public int getShopId() {
        return shopId;
    }
    
    public void setShopId(int shopId) {
        this.shopId = shopId;
    }
    
    public int getPosition() {
        return position;
    }
    
    public void setPosition(int position) {
        this.position = position;
    }}
    

    在获取的数据类中添加一个是否选中状态,在onBindViewHolder 中进行赋值判断

         //  赋值之前取消CheckBox监听
         checkBox.setOnCheckedChangeListener(null);
       
           checkBox.setChecked(data.isChecked);
      
           checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
               @Override
               public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                 data.isChecked =isChecked;
               }
           });
