I have constructed a TabHost inside my navigation drawer. That means I've created 3 Fragment with xml files each: ExhibitorFragment, TabInternationalFragment, and TabLocalFragment. Now the problem is, I can't see my tabwidget under the Toolbar even though it displays design xml in either two of the fragments.
below is my code for ExhibitorFragment.java:
public class ExhibitorFragment extends Fragment{
public ExhibitorFragment() {
// Required empty public constructor
}
private FragmentTabHost mTabHost;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
mTabHost = new FragmentTabHost(getActivity());
mTabHost.setup(getActivity(), getChildFragmentManager(), R.layout.fragment_exhibitor);
Bundle arg1 = new Bundle();
arg1.putInt("Arg for Frag1", 1);
mTabHost.addTab(mTabHost.newTabSpec("Tab1").setIndicator("Frag Tab1"),
TabInternationalFragment.class, arg1);
Bundle arg2 = new Bundle();
arg2.putInt("Arg for Frag2", 2);
mTabHost.addTab(mTabHost.newTabSpec("Tab2").setIndicator("Frag Tab2"),
TabLocalFragment.class, arg2);
return mTabHost;
}
#Override
public void onDestroyView() {
super.onDestroyView();
mTabHost = null;
}
}
fragment_exhibitor.xml :
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.guitarista.citem.Example">
<TabHost android:id="#android:id/tabhost"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TabWidget
android:id="#android:id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<FrameLayout
android:id="#+id/International"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
<FrameLayout
android:id="#+id/Local"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</FrameLayout>
</LinearLayout>
</TabHost>
</FrameLayout>
The TabInternationalFragment and TabLocalFragment are set to default when created same as their respected xml (fragment_tab_international, fragment_tab_local).
Your Java Code Is correct Try Changing the XML file to this format
<android.support.v4.app.FragmentTabHost
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost"
android:layout_marginTop="55dp"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TabWidget
android:id="#android:id/tabs"
android:layout_width="match_parent"
android:layout_height="45dp"/>
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1" />
</LinearLayout>
</android.support.v4.app.FragmentTabHost>
Usr this code
<TabHost android:id="#android:id/tabhost"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TabWidget
android:id="#android:id/tabs"
android:layout_width="match_parent"

<FrameLayout

android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</FrameLayout>
</LinearLayout>
</TabHost>
</FrameLayout>
FragmentTabHost mTabHost;
mTabHost = (FragmentTabHost) findViewById(android.R.id.tabhost);
mTabHost.setup(this, getSupportFragmentManager(), android.R.id.tabcontent);
mTabHost.addTab(mTabHost.newTabSpec("tab1").setIndicator("tab2"),
tab1.class,null);
mTabHost.addTab(mTabHost.newTabSpec("tab2")
.setIndicator("tab2"), tab2.class, null);
I've followed this tutorial Android Tabs in Fragments. Though this one is likely similar to Pager Sliding tab strip. Take Note that you still need to implement fragment codes for this to work.

I am using a class that extends Fragment and not FragmentActivity and I cannot seem to make horizontal scroll to work. I first used a layout as simple as the first code below and it works perfectly (without the scroll of course). I decided to put a horizontal scroll because when my tab reaches 6, the text is so hard to read and when the text is too long, the complete text is not written. I tried to use the layout of other people that said "This works!". Please refer to the second code below; the third code is my fragment class. Thank you!
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
The layout that other people said "It works"
<android.support.v4.app.FragmentTabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<HorizontalScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fillViewport="true"
android:scrollbars="none" >
<TabWidget
android:id="#android:id/tabs"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom" />
</HorizontalScrollView>
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" />
</LinearLayout>
</android.support.v4.app.FragmentTabHost>
Lastly, my Fragment class. Maybe I'm missing something out?
public class AlarmTab extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
FragmentTabHost tabHost;
tabHost = new FragmentTabHost(getActivity());
tabHost.setup(getActivity(), getChildFragmentManager(), R.layout.alarm_tab);
for(int i=0; i<SmashDeviceData.get_instance().devices.size(); i++) {
Bundle bundle = new Bundle();
bundle.putInt("Arg for Frag" + i, 1);
tabHost.addTab(tabHost.newTabSpec("Tab"+i).setIndicator(SmashDeviceData.get_instance().devices.get(i).deviceName), AlarmActivity.class, bundle);
}
return tabHost;
}
public static Fragment newInstance() {
Fragment fragment = new AlarmTab();
return fragment;
}
}
try the below
for xml
<android.support.v4.app.FragmentTabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:orientation="vertical" >
<HorizontalScrollView
android:id="#+id/horizontalScrollView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#color/tabsColor"
android:scrollbars="none" >
<TabWidget
android:id="#android:id/tabs"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#color/tabsColor"
android:gravity="center_horizontal" />
</HorizontalScrollView>
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</LinearLayout>
</android.support.v4.app.FragmentTabHost>
for your fragment
public class HomeFragment extends Fragment {
private FragmentTabHost mTabHost;
TabWidget widget;
HorizontalScrollView hs;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_home, container,
false);
initView(rootView);
return rootView;
}
private void initView(View rootView) {
mTabHost = (FragmentTabHost) rootView
.findViewById(android.R.id.tabhost);
widget = (TabWidget) rootView.findViewById(android.R.id.tabs);
hs = (HorizontalScrollView) rootView
.findViewById(R.id.horizontalScrollView);
mTabHost.setup(getActivity(), getChildFragmentManager(),
android.R.id.tabcontent);
}
}
I've already implemented FragmentTabHost, but my Fragments are going outside the tabhost.
Here is my Activity:
public class MainActivity extends ActionBarActivity {
private FragmentTabHost mTabHost;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mTabHost = (FragmentTabHost) findViewById(android.R.id.tabhost);
mTabHost.setup(this, getSupportFragmentManager(),android.R.id.tabhost);
mTabHost.addTab(mTabHost.newTabSpec("simple").setIndicator("Simple"),
PlaceholderFragment.class,null);
mTabHost.addTab(mTabHost.newTabSpec("contacts")
.setIndicator("Contacts"), PlaceholderFragment2.class, null);
}
}
And here is my fragment:
public class PlaceholderFragment2 extends Fragment {
public PlaceholderFragment2() {
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_main2, container, false);
return rootView;
}
}
activity_main.xml
<android.support.v4.app.FragmentTabHost
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/container"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
tools:context=".MainActivity"
/>
</android.support.v4.app.FragmentTabHost>
And fragment_main.xml
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView android:text="#string/hello_world" android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/imageView"
android:src="#drawable/ic_launcher"
android:layout_alignParentTop="true"
android:layout_alignParentStart="true"
android:layout_marginTop="159dp" />
</FrameLayout>
The problem is that the fragment goes outside it's tab.
Here's the photo
Change your activity_main.xml to
<android.support.v4.app.FragmentTabHost
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TabWidget
android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"/>
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1" />
</LinearLayout>
</android.support.v4.app.FragmentTabHost>
and your activity's onCreate to
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mTabHost = (FragmentTabHost) findViewById(android.R.id.tabhost);
mTabHost.setup(this, getSupportFragmentManager(), android.R.id.tabcontent);
mTabHost.addTab(mTabHost.newTabSpec("simple").setIndicator("Simple"),
PlaceholderFragment.class,null);
mTabHost.addTab(mTabHost.newTabSpec("contacts")
.setIndicator("Contacts"), PlaceholderFragment2.class, null);
}
Although I strongly suggestion not using a tabhost at all. I would instead go for something in the lines of this solution.
im trying to set up a FragmentTabHost with 3 tabs. The problem im having is the content of each tab is actually being displayed in the tab tittle as well. Why is this happening? The layout for tab1 has a textview that says "Tab1" this is being displayed in the tab and not the content area. also if i change the background it changes the background of the tabs not the content area.
xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<android.support.v4.app.FragmentTabHost
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<FrameLayout
android:id="#+id/realtabcontent"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
</android.support.v4.app.FragmentTabHost>
</LinearLayout>
MAIN Fragment:
public class NewFragment _Frag extends Fragment{
private FragmentTabHost mTabHost;
Intent intent;
boolean created = false;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
//return super.onCreateView(inflater, container, savedInstanceState);
if(container==null)
{
return null;
}
View v = inflater.inflate(R.layout.mylayout, container, false);
mTabHost = (FragmentTabHost)v.findViewById(android.R.id.tabhost);
mTabHost.setup(getActivity(), getChildFragmentManager(), R.id.realtabcontent);
mTabHost.addTab(mTabHost.newTabSpec("fragmentb").setIndicator("Tab1"),
myclass1.class, null);
mTabHost.addTab(mTabHost.newTabSpec("fragmentc").setIndicator("Tab2"),
myclass2.class, null);
mTabHost.addTab(mTabHost.newTabSpec("fragmentd").setIndicator("Tab3"),
myclass3.class, null);
return v;
}
First, lets assume your XML name is my_xml.xml.
So make following changes in the my_xml.xml first(Change the ID)
<android.support.v4.app.FragmentTabHost
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/my_tabhost"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
and then following changes in the java file.
mTabHost = (FragmentTabHost)v.findViewById(R.id.my_tabhost);
mTabHost.setup(getActivity(), getChildFragmentManager(), R.layout.my_xml);
you missed these two :
<TabWidget
android:id="#android:id/tabs"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0"/>
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_weight="0"/>
so add them in your Linearlayout above framelayout
actually you do not need any changes because your code is exactly like demo see below:
https://chromium.googlesource.com/android_tools/+/18728e9dd5dd66d4f5edf1b792e77e2b544a1cb0/sdk/extras/android/support/samples/Support4Demos/src/com/example/android/supportv4/app/FragmentTabs.java

I have the following class in java. My purpose is to design a tabhost and have an activity start when the first tab is displayed. Also i want to have a different activity start when another tab is clicked.
I have implemented the onTabChanged method but it doesn't seem to work. Can you help me?
Here is my class:
public class Tabs extends Activity implements OnTabChangeListener{
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.tabs);
TabHost th = (TabHost) findViewById(R.id.tabhost);
th.setup();
TabSpec profile = th.newTabSpec("tag1");
profile.setContent(R.id.tab1);
profile.setIndicator("", getResources().getDrawable(R.drawable.profile_tab));
TabSpec matches = th.newTabSpec("tag2");
matches.setContent(R.id.tab2);
matches.setIndicator("", getResources().getDrawable(R.drawable.matches_tab));
TabSpec friends = th.newTabSpec("tag3");
friends.setContent(R.id.tab3);
friends.setIndicator("", getResources().getDrawable(R.drawable.friends_tab));
th.addTab(profile);
th.addTab(matches);
th.addTab(friends);
}
#Override
public void onTabChanged(String arg0) {
// TODO Auto-generated method stub
}
}
This is my tabs.xml layout file:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TabHost
android:id="#+id/tabhost"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TabWidget
android:id="#android:id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</TabWidget>
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:id="#+id/tab1"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<include layout="#layout/activity_main"/>
</LinearLayout>
<LinearLayout
android:id="#+id/tab2"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<include layout="#layout/matches_page"/>
</LinearLayout>
<LinearLayout
android:id="#+id/tab3"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</LinearLayout>
</FrameLayout>
</LinearLayout>
</TabHost>
</LinearLayout>
you miss th.setOnTabChangeListener(this);
You have to inform TabHost which implementation of the OnTabChangeListener interface has to call
The graphical layout for a simple android.support.v4.app.FragmentTabHost never renders in either Eclipse or Android Studio.
The Console error I get is consistently:
Exception raised during rendering: No tab known for tag null
I'm using the most basic XML file:
<android.support.v4.app.FragmentTabHost
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TabWidget
android:id="#android:id/tabs"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0"/>
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_weight="0"/>
<FrameLayout
android:id="#+id/realtabcontent"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"/>
</LinearLayout>
</android.support.v4.app.FragmentTabHost>
but the same error occurs.
I just wanted to add more views above or below the tab widget and frame layout.
I don't care so much about seeing the tab content; I just want to see the rest of my layout - but the problem is that NO OTHER VIEWS are rendered when a android.support.v4.app.FragmentTabHost resides in the layout.
I've read and tried to resolve the issue from the answer to this post:
Android: Tabs at the bottom with FragmentTabHost
but I don't think that that is my problem; I'm not looking to put a TabWidget on the bottom.
Every other one of my XML files opens perfectly.
The same problem occurs in Android Studio:
I had the same rendering problem as well as compilation error. I fixed the problem by finding that I was not passing Fragment when i was creating Addtab. You must pass atleast one fragment on mTabHost.addTab. Below is the working code.
private FragmentTabHost mTabHost;
mTabHost = (FragmentTabHost)findViewById(android.R.id.tabhost);
mTabHost.setup(HomeActivity.this, getSupportFragmentManager(), android.R.id.tabcontent);
mTabHost.addTab(mTabHost.newTabSpec("home").setIndicator("Home"), HomeFragment.class, null);
mTabHost.addTab(mTabHost.newTabSpec("mysheets").setIndicator("MySheets"));
mTabHost.addTab(mTabHost.newTabSpec("bookmarks").setIndicator("Bookmarks"));
Not sure about the error you've got (sorry, I'm really busy right now so can't spend more time checking) but in general it seems that the FragmentTabHost from the support libs doesn't care about the xml at all. See my previous answer to another question:
FragmentTabHost with horizontal scroll
From Layout i am getting the same Error..so,I resolve that Problem by Code only...It's working fine..Please try this code
import android.os.Bundle;
import android.support.v4.app.Fragment;

}
If U need to put fragmented tabs at bottom of screen ...
#fallow undermentioned --
Make your xml file like this ..
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<!-- <RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"> android:layout_alignParentTop="true" -->
<FrameLayout
android:id="#+id/realtabcontent"
android:layout_width="match_parent"
android:layout_height="0dip"
android:layout_weight="1" />
<android.support.v4.app.FragmentTabHost
android:id="#android:id/tabhost"
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="0dip"
android:layout_height="0dip"
android:layout_weight="0" />
</android.support.v4.app.FragmentTabHost>
</LinearLayout>
Now if your concern is opening several fragments with in single fragmented tabs ...
#follow steps ::
Create a container fragment. This container fragment will be default for all of your's tabs content.
For every tab content replace fragment U need with this container.
For ex:- Just like you replace your bed with different bed sheets .. :)
Your container fragment class that will be used differently in different tabs ... "LearnContainerFragment.java "
public class LearnContainerFragment extends BaseContainerFragment {
private boolean mIsViewInited;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
Log.e("test", "tab 1 oncreateview");
return inflater.inflate(R.layout.container_fragment, null);
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
Log.e("test", "tab 1 container on activity created");
if (!mIsViewInited) {
mIsViewInited = true;
initView();
}
}
private void initView() {
Log.e("test", "tab 1 init view");
replaceFragment(new Learn(), false);
}
}
LearnContainerFragment.java --- > it's xml file container_fragment.xml
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/container_framelayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
# How to use Conatiner..
For every fragment U need will be replaced with id of this container fragment.
#last your BaseContainerFragment.java class --
public class BaseContainerFragment extends Fragment {
public void replaceFragment(Fragment fragment, boolean addToBackStack) {
FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
if (addToBackStack) {
transaction.addToBackStack(null);
}
transaction.replace(R.id.container_framelayout, fragment);
transaction.commit();
getChildFragmentManager().executePendingTransactions();
}
public boolean popFragment() {
Log.e("test", "pop fragment: " + getChildFragmentManager().getBackStackEntryCount());
boolean isPop = false;
if (getChildFragmentManager().getBackStackEntryCount() > 0) {
isPop = true;
getChildFragmentManager().popBackStack();
}
return isPop;
}
}
Hope it helps.....
Cheers!
not sure.... but shouldn't your layout have a tabhost tag in it above the tabwidget's linear layout?
<TabHost
android:id="#+id/tabhost"
