我有一个电池适配器，用于我所有的listViews。不同类型的清单由参数TableType确定。设置标签不一致
TableTypes 1和2也使用外部库，允许用于保存和删除的滑出功能。由于这个库OnClickListeners在列表视图类的结果将不会为TableType 1和2
工作因此我已经在细胞适配器本身（该onClickListener对于标签的“小区”的部分）添加OnClickListener。单元适配器比使用接口参数来调用必要的方法。
这里的不一致是TableType 1正确无误地执行。 TableType 2不是但是作为标签返回它上面的项目的位置。
I.E.如果TableType 2有4项，第2项将带有标签1，第3项将有标签2.我不知道为什么会这样，因为代码是相同的TableType 1和2之间
