I am facing the very weird problem,i found the similar kind of problem over the net but none of the solution helps me to get rid of this.
Problem ::
I am having a one fragment which have 3 tabs,(tabs created using fragment tab host).Now every tabs have different fragment.
From first tab,i have set one fragment where i have used view pager and circle page indicator to display the images with dots(circle).
Now when i swipe the image from 1st to 2nd then 3rd and so on,it works fine. But after reaching on image 2nd,when i click on tab2 and again came back to tab1,my images lost.
Your guidance or any help/links will be appreciated..
Many many thanks in advance.
For your understanding here i am posting code below ::
FragmentwithTabHost ::
public class FragmentwithTabHost extends Fragment{
private View rootView;
private FragmentTabHost mTabHost;
private Context mContext;
public FragmentwithTabHost() {
}
public FragmentwithTabHost(Context ctx) {
mContext=getActivity();
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
rootView = inflater.inflate(R.layout.mycardswithtabs, container,
false);
mTabHost = (FragmentTabHost) rootView.findViewById(android.R.id.tabhost);
mTabHost.setup(getActivity(), getChildFragmentManager(), android.R.id.tabcontent);
mTabHost.setBackground(getActivity().getResources().getDrawable(R.drawable.normal));
mTabHost.addTab(
mTabHost.newTabSpec("tab1").setIndicator("tab1", null),
Fragment1.class, null);
mTabHost.addTab(
mTabHost.newTabSpec("tab2").setIndicator("tab2", null),
Fragment2.class, null);
mTabHost.addTab(
mTabHost.newTabSpec("tab3").setIndicator("tab3", null),
Fragment3.class, null);
return rootView;
}
}
