how can i solve

Answer 1

I got a similar problem on using tabHost in fragments, searched a lot and finally found a solution to that.

1) Keep you code in on create view

2) This is the key -> While inflating the layout for tab indicators use as follows

View tabIndicator = LayoutInflater.from(getActivity()).inflate(R.layout.tab_indicator, mTabHost.getTabWidget(), false);

We need to set the parent value in the inflater as mTabHost.getTabWidget()

Setting tab indicator using the above code solved the issue of

          Java : illegal state exception : no tab know for tag null

Update :

mTabHost = (FragmentTabHost) view.findViewById(android.R.id.tabhost);

mTabHost.setup(getActivity(), getChildFragmentManager(), R.id.realtabcontent);

View tabIndicatorToday = LayoutInflater.from(getActivity()).inflate(R.layout.tab_indicator, mTabHost.getTabWidget(), false);
        ((TextView) tabIndicatorToday.findViewById(R.id.tv_tab_txt)).setText(getResources().getString(R.string.text));

mTabHost.addTab(mTabHost.newTabSpec(getResources().getString(R.string.text)).setIndicator(tabIndicatorToday), Fragment.class, null);
