Replacing ViewPager with Fragment - Then Navigating Back

由 时光总嘲笑我的痴心妄想 提交于 2019-11-26 19:29:26
问题 I've got an activity which initially hosts a ViewPager, hooked up to a FragmentPagerAdapter. When the user clicks on an item inside the ViewPager's child fragment, I'm using a FragmentTransaction to replace an empty container view with a new Fragment which I want to navigate to. If I use addToBackStack() on the transaction, commit the transaction and then navigate back, I am not returned to the ViewPager's views (the initial layout). If I don't use addToBackStack() on the transaction, commit

问题 I want to have different tabs, where you can swipe through like in the android market. Each tab should use one fragment and use one method for it. This is my FragmentPagerAdapter class: public class SectionsPagerAdapter extends FragmentPagerAdapter { public SectionsPagerAdapter(FragmentManager fm) { super(fm); } @Override public Fragment getItem(int position) { Fragment fragment =null; switch (position) { case 0: fragment = new ConnectionFragment(); break; case 1: fragment = new DataFragment(

问题 What is the difference between FragmentPagerAdapter and FragmentStatePagerAdapter ? About FragmentPagerAdapter Google\'s guide says: This version of the pager is best for use when there are a handful of typically more static fragments to be paged through, such as a set of tabs. The fragment of each page the user visits will be kept in memory, though its view hierarchy may be destroyed when not visible. This can result in using a significant amount of memory since fragment instances can hold
