I have tried using FragmentTabHost. all went well, and has managed to show the tab well. but my fragment not showing layout of that class. I've tried using the TextView, but still did not appear.
please help me.
My FragmentActivity
public class ViewDetailAnak extends FragmentActivity{
private static String idanak;
private FragmentTabHost tabHost;
private static final String TRANS_SPEC = "";
private static final String US_SPEC = "";
private static final String TABU_SPEC = "";
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fro_single_item_anak);
tabHost = (FragmentTabHost)findViewById(android.R.id.tabhost);
tabHost.setup(this, getSupportFragmentManager(),android.R.id.tabcontent);
tabHost.addTab(
tabHost.newTabSpec(TRANS_SPEC)
.setIndicator(TRANS_SPEC, getResources().getDrawable(R.drawable.icon_trans)),
FROVDATransaksi.class, null);
tabHost.addTab(
tabHost.newTabSpec(US_SPEC)
.setIndicator(US_SPEC, getResources().getDrawable(R.drawable.icon_us)),
FROVDAUangsaku.class, null);
tabHost.addTab(
tabHost.newTabSpec(TABU_SPEC)
.setIndicator(TABU_SPEC, getResources().getDrawable(R.drawable.icon_tab)),
FROVDATabungan.class, null);
}
One of 3 fragment
public static class FROVDAUangsaku extends Fragment {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fro_vda_uangsaku, container, false);

The error states clearly. Inside history_list_details_fragment.xml there is no Toolbar. Try to add it.
Or more probably the Toolbar is in you Activity layout, so init it inside Activity.

My fragment
public class Frag_Menu extends Fragment {
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.frag_menu, container, false);
return view;
}
public void onActivityCreated(Bundle savedInstanceState) {

if(null!=layout)
layout.removeView(layout);
};
public static android.support.v4.app.Fragment newInstance(String string) {
return null;
}
}
You can use getActivity().findViewById() to get your Button from the fragment class in onActivityCreated().
View button = getActivity().findViewById(R.id.butBack);
if (button != null && button.getParent() != null) {
((ViewGroup)button.getParent()).removeView(button);
}
I detect the WIFI connect , when WIFI connect is break.
It will show the framelayout on the top of all widgets.
public class MjpegPlayerFragment extends Fragment {
public static FrameLayout reconnect_layout;
private class GetTimeStamp extends AsyncTask<URL, Integer, String> {
protected void onPostExecute(String result) {
Activity activity = getActivity() ;
if (activity != null) {
reconnect_fragment();
}
super.onPostExecute(result) ;
}
}
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.preview_player, container, false) ;
reconnect_layout = (FrameLayout) getActivity().findViewById(R.id.reconnect_layout);
return view ;
}
public static void reconnect_fragment() {
reconnect_layout.setVisibility(View.VISIBLE);
}

When it call the reconnect_fragment(); it show the java.lang.NullPointerException at reconnect_layout.setVisibility(View.VISIBLE);
Does there has any wrong ?
How to solve this problem ?
As you said in your comment framelayout is in fragment layout
So Change to
reconnect_layout = (FrameLayout) view.findViewById(R.id.reconnect_layout);
If it is in activity xml you use getActivity().findViewById
replace
reconnect_layout = (FrameLayout) getActivity().findViewById(R.id.reconnect_layout);
with
reconnect_layout = (FrameLayout) view.findViewById(R.id.reconnect_layout);

and using this code to work with tab host in my fragment class
public class HostFragment extends Fragment {
private FragmentTabHost mTabHost;
public HostFragment() {
// Empty constructor required for fragment subclasses
}
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_host_layout,
container, false);
setHasOptionsMenu(true);
TabHost mTabHost = (TabHost) rootView.findViewById(R.id.tabhost);
mTabHost.setup( );
TabSpec photospec = mTabHost.newTabSpec("Search");
photospec.setIndicator("Search",
getResources().getDrawable(R.drawable.action_search));
Intent searchIntent = new Intent(getActivity(),
HostViewIntroduce.class);
photospec.setContent(searchIntent);
TabSpec songspec = mTabHost.newTabSpec("Favorites");
songspec.setIndicator("Favorites",
getResources().getDrawable(R.drawable.action_search));
Intent favoriteIntent = new Intent(getActivity(),
HostViewTips.class);
songspec.setContent(favoriteIntent);
mTabHost.addTab(songspec);
mTabHost.addTab(photospec);
return rootView;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// TODO Auto-generated method stub
return super.onOptionsItemSelected(item);
}
}
and it throw nullpointer exception

You need to use FragmentTabHost's custom addTab() which will also take your Fragment class as parameter.
Replace
TabSpec photospec = mTabHost.newTabSpec("Search");
photospec.setIndicator("Search",
getResources().getDrawable(R.drawable.action_search));
Intent searchIntent = new Intent(getActivity(),
HostViewIntroduce.class);
photospec.setContent(searchIntent);
TabSpec songspec = mTabHost.newTabSpec("Favorites");
songspec.setIndicator("Favorites",
getResources().getDrawable(R.drawable.action_search));
Intent favoriteIntent = new Intent(getActivity(),
HostViewTips.class);
songspec.setContent(favoriteIntent);
with
TabHost.TabSpec photospec = mTabHost.newTabSpec("Search");
photospec.setIndicator("Search",
getResources().getDrawable(R.drawable.action_search));
photospec.setIndicator(rootView);
mTabHost.addTab(photospec, HostViewIntroduce.class, null);
TabSpec songspec = mTabHost.newTabSpec("Favorites");
songspec.setIndicator("Favorites",
getResources().getDrawable(R.drawable.action_search));
songspec.setIndicator(rootView);
mTabHost.addTab(songspec, HostViewTips.class, null);
i am using fragment in my application.there are 5 tabs.in 1 tab i need to inflate a list view on a button click.given below is my code for that tab.

LinearLayout theLayout;
Store store;
#SuppressWarnings("static-access")
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
if (container == null) {
}
theLayout = (LinearLayout) inflater.inflate(
R.layout.tab_store_locator_layout, container, false);
phoneLocationButton = (RelativeLayout) theLayout.findViewById(R.id.phone_location_button);

store.setState("california");
phoneLocationButton.setOnClickListener(this);

storeFlipper.addView(storeList);
StoreAdapter adapter = new StoreAdapter(getActivity(), R.layout.store_list_item);
