问题 In my application I am using the following means to render/generate the views to a view pager. Yes it works fine and as expected.

Then, within on create, I changed my constructor: mTabsAdapter = new TabsAdapter(this.getSupportFragmentManager(), this, mViewPager); From there, in my subclass, I changed the code to reflect this: public TabsAdapter(FragmentManager fm, Activity activity, ViewPager pager) { super(fm)

问题 So, I have this ScrollView with one child - a LinearLayout that has two children: a TextView and a ViewPager . ViewPager contains layout with many elements, that's why i need the ability to scroll vertically. Only pages in ViewPager may be scrolled horizontally (that is: I'd like to swipe horizontally only within the ViewPager ).

That means that when the user swipes between views and have seen all views inside a viewpager, then show a save button. I want to show the save button on every view when they have seen all views hereby after. The trouble I am having is how to set up the logic.
