Answer 2

单独的上下滑动数据混乱那个解决了、现在的问题是第一次从数据库里查数据、然后判断checkbox是选中还是不选中、checkbox有个默认状态（打钩或者不打钩）、然后上下滑动的时候是从缓存里面取数据判断、但是会和从数据里查的数据相互覆盖、

Answer 3

这个方法是上下滑动保存当前position checkbox选中和不选中的、即为缓存数据 
 private void setOnCheck(ViewHolder viewHolder, final int position) {
        viewHolder.defence_off.setOnCheckedChangeListener(new OnCheckedChangeListener() {
            // 记录撤防checkbox选中和不选中状态
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                if (isChecked) {
                    mOffState.put((Integer) buttonView.getTag(), position);
                } else {
                    mOffState.remove((Integer) buttonView.getTag());
                }
            }
        });
        viewHolder.defence_on.setOnCheckedChangeListener(new OnCheckedChangeListener() {
            // 记录布防checkbox选中和不选中状态
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                if (isChecked) {
                    mOnState.put((Integer) buttonView.getTag(), position);
                } else {
                    mOnState.remove((Integer) buttonView.getTag());
                }
            }
        });
    }
