Is it possible to create a ViewPager with the following scenario?
I want to have a ViewPager with 5 fragments. These 5 fragments are bound to a ViewPagerIndicator. (already got this)
Now I want to create an extra fragment at the start before all other fragments and that the ViewPagerIndicator is not selecting anything when this fragment is the current item.
Does anyone know if this is possible?

I have a Fragment with TabLayout, and selecting by current tab it shows the selected month info, not hiding tabs bar and don't using for that many fragments, just updating the view. And now i need swipe tabs by finger sliding. I've searched and watch many examples which using ViewPager and many Fragments to describe each tab.
So how can i do this using only one fragment not other fragments?
I build an application which has tabs in it, and using ViewPager to swipe between the tabs.
Is it possible that one tab will show firstFragment, and then when pressing a Button will show firstFragment and secondFragment?
Of coarse you can. When you bind ViewPager to TabLayout you use adapter, which extends FragmentPagerAdapter, that adapter stores list of all fragments and layout texts. Just replace fragment in it and invalidate result.
But, this should by done from Activity, which has ViewPager and TabLayout.
Define interface in your first program, implement it in Activity and replace fragment on button click.
once again, I am following this tutorial: androidhive - tab layout with swipe able views . All 3 fragment tabs are loaded with different information and logic and layouts. I would like to refresh each fragment when their tabs have been clicked as it auto loads the fragments from start as it uses the view pager. Is there any simplest way out that I could load only a/1 fragment using view pager? Or to reload the fragments? Thanks for your help!
Try to add this to your viewpager:
MY_VIEWPAGER.setOffscreenPageLimit(0);
Check out the documentation.
Pages beyond this limit will be recreated from the adapter when needed.
The limit of 0 will cause a recreation of the fragment when you open a tab.
I have a custom ViewPager in which I have 4 fragments, each fragment has different listviews, and its on the start screen of the application. The listview's are taking time to load as soon as the application starts. I'm not pulling any data into the listview, its just the implementation. Implemented OnPageChangeListener to change the listview as I swipe through the fragments
Why does this happen?
changed the implementation, instead of fragments I used PagerAdapter.
I'm developing an app, which consist of:
1. main activity, which has action bar, list fragment and some buttons at bottom
2. when you click on some item, another activity is launched - some buttons at top and webview under it.
I have everything working, but now I have to implement swiping between items from list, and I cant figure out how to swipe between activities. I though of changing items into fragments but then I have no idea, how layout should be worked out. I've read blog about viewpager, but as I understood, you can swipe only between 5 tabs with it, and I have 20+ items in listfragment. any ideas? thanks
create one Activity with ViewPager as it's main control. change items into fragments and add them to the ViewPager via FragmentAdapter
You can go ahead and user viewpager. there is no arbitrary limit to the number of pages.
It would be the quickest solution for you and seems to cover what you are doing.
