Avoid recreating same view when perform tab switching

Question

Current, I have 2 Fragments, which is switch-able through ActionBar\'s tab.

    getSupportActionBar().setNavigationMode(ActionBar.NAVIG         


        

Answer 1

The following solution works for me. It prevents Fragment's onCreateView to be called when switching tabs.

Activity's onCreate should add all fragments and hide all except the one for the first tab:

ft.add(R.id.fragment_content, secondTabFragment);
ft.hide(secondTabFragment);
ft.add(R.id.fragment_content, firstTabFragment);
ft.show(firstTabFragment);
ft.commit();
currentFragment = firstTabFragment;

Activity's onTabSelected should just hide the current fragment and show the fragment corresponding to the chosen tab.

ft.hide(currentFragment);
ft.show(chosenFragment);
ft.commit();
currentFragment = chosenFragment;

Beware that changing the device orientation will restart your Activity and then recreate your Fragments. You can avoid that by adding this configChanges in your Manifest:
