67 
68     android:gravity="center_vertical" />

这样的话在第一行的separator之后会有thumbnailItem (在左边) 以及 checkbox（在右边）最后有descriptionItem 但是上面的代码还是存在一点小问题

1.thumbnail没有出现

这是因为thumbnail 的第二个textview的属性设置有问题导致拉长到铺满整个页面，把description挤出去了

2.checkbox 没有到理想的最右边

这里需要用到alignParentRight 所以相应修改relativeLayout

下面是修正后的版本
