PagerSlidingTabStrip：如何在当前标签页在运行时刷新内部片段ListView和停止加载数据的下一个标签 [英] PagerSlidingTabStrip: How refresh inner fragment Listview in current tab at run time and stop the loading data for next tab
问题描述
我被困与内片段insideNavigation抽屉页的滑动片，带viewpager标签使用列表视图的问题，在的这个混帐枢纽例子。
I got stuck into the problem with listview used with inner fragment insideNavigation-drawer-page-sliding-tab-strip viewpager tabs, that given in This git hub example.
我使用的是同一个例子，有一个列表视图不同的ArrayList设置有适配器，所有4个标签。
i am using the same example and All 4 tabs having a list view with different arraylist set to there adapters.
我只用一个片段和标签位置基地我加载不同的列表数据内片段arrayAdapter。另外我有两个按钮，一个是删除，另一种是添加。
I am using only one fragment and bases of tabs position I am loading different list data to inner fragment arrayAdapter. Also I have two buttons one is delete and another one is Add.
我要什么：如果我preSS Add按钮，那么就应该新数据添加到数组列表（基于标签的位置增加新加入到各自的ArrayList），并刷新列表视图的数据。
What I want: If I press the add button then it should add new data to the array list(based on the tab position add the new add to respective arrayList) and refresh the listview data.
在我的code其刷新当前查看选项卡，但在接下来的选项卡的列表视图也令人耳目一新，并采取previous选项卡中的数据。请帮我在这，任何帮助，将AP preciated。
In my code its refreshing the current viewing tab but in next tab listview also refreshing and taking the data of previous tab. Please help me on this, any help would be appreciated.
我有一个类文件这一点。如果我的做法是错误的，请告诉我们正确的做法。
I have single class file for this. If my approach is wrong please let me know correct approach.
