问题 I am implementing tabs using FragmentTabHost of v4 support library. My first tab contains the list of items.When I click on list item it should move to tab 2.

问题 I'm using tabHost in my application but in one of the views (corresponding to one of the tabs) I have a button that have to take me to another activity and then another layout. The question is: how do I get this new layout can continue to have access to the tabs? or better say, How do I load this new layout inside the FrameLayout ?.

问题 I am working with the support library ActionBar because I'm using an older minimum SDK. In the activity, I am using FragmentTabHost because I have 3 tabs. The ActionBar also has a SearchView, so when a search is made, the 3rd tab is switched out with the results of the search. I am able to get intput from the SearchView, but I am unable to switch out the 3rd tab when I have a search result.

问题 Can anyone point me to an example or show me how to create a simple Tabbed Dialog in Android where the contents of each tab are Fragments ? All the examples/tutorials I have found are about Fragments and Tabs, but nothing specific to DialogFragments . The documentation for FragmentTabHost shows how to create tabs within normal fragments using getChildFragmentManager() .

问题 I am having an issue getting the view to change on a tabhost - when I select a tab the content stays blank. From what I can tell, onCreateView is not being called on the child Fragments . onMenuCreate runs fine because the menu changes like it is supposed to. public class PatientTabFragment extends Fragment { private FragmentTabHost mTabHost; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { mTabHost = new FragmentTabHost(getActivity

Do I uses getChildFragmentManager() to do this? How do I do so?
