notifyDataSetChanged用于多个复选框 [英] notifyDataSetChanged for multiple checkboxes

问题描述

code>在一个活动中显示SelectAll复选框，在适配器中显示所有复选框。
如果i 选中SelectAll ，则在适配器中选中所有复选框，如果取消选中，则取消选中所有复选框。

In attached image, SelectAll checkbox is present with in an activity, and all checkboxes within adapter. If i checked SelectAll then all checkboxes are checked in adapter and if I unchecked then all are unchecked. Its happening nicely.

但我想如果我选中SelectAll ，之后如果i uncheked 一个或多个复选框，然后 SelectAll复选框应取消选中。
如果没有勾选SelectAll如果我手动检查适配器中的所有复选框，然后 SelectAll复选框应该自动选中。

But I want if I checked SelectAll and after that if i uncheked one or more checkbox in tha adapter then the SelectAll checkbox should unchecked. and if without check to SelectAll If i manually check all the checkboxes in adapter then SelectAll checkbox should checked automatically.

我如何做。
