EDIT: I found out that the Activity is saving the instance, but the Fragments saved data is not making it up to the Activity savedInstanceState. I'm saving the current time in the outState, but its not making its way all the way up, as the activity has nothing in its SavedInstanceState for the time and returns 'null' for the time if I print it to the logcat.... I am building an application that has the a countup and countdown timer built in. The basic hosting activity for the timers is a FragmentActivity which hosts a FragementPagerAdapter that inflates two fragments within the code (I do not

问题 I'm trying to make a slidescreen with viewpager and fragments so that I can load different layouts per fragment and give each page different functionality. I followed a tutorial to accomplish this.

Save State and Restore State in FragmentStatePagerAdapter

风格不统一 提交于 2019-12-03 15:01:30

Having mViewPager.setOffscreenPageLimit(4); is not a good option as it has memory issues. I searched a

I have a fragment that contains a ViewPager . This ViewPager is backed by a PagerAdapter that uses a Cursor . The cursor is managed by LoaderCallbacks . I'm using the v4 support libraries here.

I know that ViewPager has a setCurrentItem() method, but the data may not yet be loaded when the ViewPager is created. What I need is to listen to the adapter for data set changes, and if that is the first such change, then call setCurrentItem() on ViewPager . However the PagerAdapter
