Hello I am having difficulty changing the visual view of the fragment activity. I created all the tabs but onClick I do not know how to pass the activity into that white space.
so the structure of this is a simple activity named Main which just sets the content view to a maintabholder.xml document that holds the fragment view which connects to a class named MainNav whose content view contains all the tabs at the bottom.
maintabholder.xml:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
>
<include layout="#layout/header" android:layout_alignParentTop="true" android:id="#+id/headerArea"></include>
<fragment
class="my.package.name.MainNav"
android:id="#+id/fragment_tabs"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</LinearLayout>
MainNav.java code snippet:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState)
{
mRoot = inflater.inflate(R.layout.fragment_tabs, null);
mTabHost = (TabHost) mRoot.findViewById(android.R.id.tabhost);
setupTabs();
return mRoot;
}
and R.layout.fragment_tabs:
<?xml version="1.0" encoding="utf-8"?>
<TabHost
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#EFEFEF">
<RelativeLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TabWidget
android:id="#android:id/tabs"
android:layout_alignParentBottom="true"
android:layout_width="fill_parent"
android:background="#drawable/tab_background"
android:gravity="center_horizontal"
android:layout_height="wrap_content" >
</TabWidget>
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<FrameLayout
android:id="#+id/tab_1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<FrameLayout
android:id="#+id/tab_2"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<FrameLayout
android:id="#+id/tab_3"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<FrameLayout
android:id="#+id/tab_4"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<FrameLayout
android:id="#+id/tab_5"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</FrameLayout>
</RelativeLayout>
and Finally the contents of an Activity that I want to load into the Fragment (upon pressing the tab1 button)
public class HomeFragment extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.home);
}
}
That is to help you get the gist of things, but the problem occurs here in MainNav.java:
#Override
public void onTabChanged(String tabId) {
Log.d(TAG, "onTabChanged(): tabId=" + tabId);
if (TAB_HOME.equals(tabId)) {
updateTab(tabId, R.id.tab_1);
mCurrentTab = 0;
return;
}
}
when a tab is clicked, it is registered in the onTabChanged activity, and the updateTab function is called:
private void updateTab(String tabId, int placeholder) {
FragmentManager fm = getFragmentManager();
if (fm.findFragmentByTag(tabId) == null) {
//fm.beginTransaction()
// .replace(placeholder, /*need fragment object here*/ , tabId)
// .commit();
//
}
}
the commented out replace method is looking for an (int, fragment, string) and I guess it should then change the white space for me.
but I don't understand where I get the fragment object from! This phantom object needs to somehow contain my HomeFragment's xml layout and allow me to interact with everything else I've coded for the HomeFragment activity.
My first hunch is that my HomeFragment activity needs to extend FragmentActivity instead
just activity. But this is where I am hitting a wall.
There is very little documentation on the compatibility pack methods, but the documentation for TabActivity says not to use TabActivity anymore, so here I am. Developing for Android 2.2+
Insight appreciated.
You can't put Activities into Fragments, it's jut that simple. You have to convert your Activities that serve the tab-contents into Fragments. It shouldn't be a problem, given that you don't use fragments in those Activities.
So here are 2 rules to follow:
You can't put Activities into Fragments.
You can't put Fragments into Fragments.
I recommend that you keep that bottom fragment on your layout around just to handle the tab-switches in the tab-widget. If a tab switch happens, you report this to the parent Activity, which will load the corresponding Fragment into the are above the tab-fragment. For this to work, you'd have to modify you layout so it has a ViewGroup above the tab-fragment and below the header. You'd dynamically load the fragments with the tab-contents into that ViewGroup.
Here's the layout (maintabholder.xml):
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
>
<include layout="#layout/header" android:layout_alignParentTop="true" android:id="#+id/headerArea"></include>
<FrameLayout android:id="#+id/TabContent"
android:layout_width="fill_parent"
android:layout_height="0dip"
android:layout_weight="1"/>
<fragment
class="my.package.name.MainNav"
android:id="#+id/fragment_tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</LinearLayout>
When a tab-switch happens in your bottom fragment, you tell this to the parent Activity:
...
(YourActivity)getActivity().switchToTab(tabId);
...
And in the YourActivity:
...
public void switchToTab(int tabId){
switch(tabId){
...
case 2:
getSupportFragmentManager().beginTransaction().replace(R.id.TabContent, TabContentFragment2.newInstance(), "someTag").commit().
break;
...
}
}
Something like that.

I am trying to make an activity containing two fragments.The first one has 3 nested fragments which I will use as a tabs and the second one only contains buttons. I don't want to add the buttons fragment into other fragments because I don't want it to reload. Right now i don't have any errors but my buttons fragment doesn't show up. Here are my fragments and my activity.
my main activity:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().requestFeature(Window.FEATURE_ACTION_BAR);
setContentView(R.layout.activity_main);
Fragment statistics = new StatisticsFragment();
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.add(R.id.fragment_statistics, statistics).commit();
Fragment buttons = new MainPageButtonsFragment();
FragmentTransaction buttonsTransaction = getSupportFragmentManager().beginTransaction();
buttonsTransaction.add(R.id.main_page_buttons_fragment,buttons).commit();
his layout
<RelativeLayout android:orientation="vertical" >
<FrameLayout
android:id="#+id/fragment_statistics"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<FrameLayout
android:id="#+id/main_page_buttons_fragment"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="#id/fragment_statistics"/>
I wont write my buttons fragment because it is not necessary I will only say its root tag is FrameLayout.
my statistics fragment (the one with tabs)
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
Fragment currentDayFragment = new CurrentDayFragment();
FragmentTransaction transaction1 = getChildFragmentManager().beginTransaction();
transaction1.add(R.id.current_day_fragment, currentDayFragment).commit();
Fragment configurationInfoFragment = new ConfigurationInfoFragment();
FragmentTransaction transaction2 = getChildFragmentManager().beginTransaction();
transaction2.add(R.id.configuration_info_fragment, configurationInfoFragment).commit();
Fragment expensesInfoFragment = new ExpensesInfoFragment();
FragmentTransaction transaction3 = getChildFragmentManager().beginTransaction();
transaction3.add(R.id.expenses_info_fragment, expensesInfoFragment).commit();
LayoutInflater lf = getActivity().getLayoutInflater();
View statisticsView = lf.inflate(R.layout.fragment_statistics, container, false);
return statisticsView;
}
his layout:
<FrameLayout >
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:id="#id/current_day_fragment"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<FrameLayout
android:id="#id/configuration_info_fragment"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<FrameLayout
android:id="#id/expenses_info_fragment"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</android.support.v4.view.ViewPager>
the nested fragments just have root tag FrameLayout and couple of TextViews in it. The result is just an activity with 3 tabs and no buttons fragment.
I am new to android programming and I am completely lost in this. Help Please!
Try using giving custom height like this....
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<FrameLayout
android:id="#+id/fragment_statistics"
android:layout_width="fill_parent"
android:layout_height="250dp"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
<FrameLayout
android:id="#+id/main_page_buttons_fragment"
android:layout_width="fill_parent"
android:layout_height="250dp"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentBottom="true" />
</RelativeLayout>
Relative layout does not have android:orientation param
I thing first fragment cover second one
Change relative layout with LinearLayout
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:id="#+id/fragment_statistics"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<FrameLayout
android:id="#+id/main_page_buttons_fragment"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="#id/fragment_statistics"/>
</LinearLayout>
I am trying to create a set of vertical tabs within an android project, I have been looking at a number of tutorials and posts on SO but cannot seem to piece it all together.
I created a new project with a fragment so I have a main.xml and a fragment_main.xml, a main activity class and a mainfragment class.
main.xml
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:id="#+id/fragment"
android:name="com.example.android.MainScreenActivityFragment"
tools:layout="#layout/fragment_main" android:layout_width="match_parent"
android:layout_height="match_parent" />
fragment_main.xml
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout android:orientation="horizontal"
android:layout_width="fill_parent" android:layout_height="fill_parent">
<FrameLayout android:layout_width="0dip"
android:layout_height="fill_parent" android:layout_weight="0.2">
<TabWidget android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:visibility="gone"/>
<LinearLayout
android:id="#+id/tab_btn_container"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<Button android:layout_height="0dip"
android:layout_width="fill_parent"
android:layout_weight="1.0"
android:background="#color/sunshine_blue"
android:id="#+id/patient_tab_btn"
android:onClick="tabHandler"/>
<Button android:layout_height="0dip"
android:layout_width="fill_parent"
android:layout_weight="1.0"
android:background="#color/sunshine_blue"
android:id="#+id/relations_tab_btn"
android:onClick="tabHandler"/>
<Button android:layout_height="0dip"
android:layout_width="fill_parent"
android:layout_weight="1.0"
android:background="#color/sunshine_blue"
android:id="#+id/providers_tab_btn"
android:onClick="tabHandler"/>
</LinearLayout>
</FrameLayout>
<FrameLayout android:id="#android:id/tabcontent"
android:layout_width="0dip"
android:layout_height="fill_parent" android:layout_weight="0.8"/>
</LinearLayout>
The main activity doesnt do anything other than the defaults and I havent added to it as I thought I should use a fragment as the google sunshine app uses a fragment for the main screen.
main fragment class
private FragmentTabHost mTabHost;
Button patientButton, relationsButton, providersButton;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_main, container, false);
mTabHost = new FragmentTabHost(getActivity());
mTabHost.setup(getActivity(), getChildFragmentManager(), R.id.tab_btn_container);
patientButton = (Button)rootView.findViewById(R.id.patient_tab_btn);
relationsButton = (Button)rootView.findViewById(R.id.relations_tab_btn);
providersButton = (Button)rootView.findViewById(R.id.providers_tab_btn);
return rootView;
}
public void tabHandler(View target){
Log.d(LOG_TAG, "Calling tabHandler() method");
patientButton.setSelected(false);
relationsButton.setSelected(false);
providersButton.setSelected(false);
if(target.getId() == R.id.patient_tab_btn){
//mTabHost.setCurrentTab(0);
patientButton.setSelected(true);
} else if(target.getId() == R.id.relations_tab_btn){
//mTabHost.setCurrentTab(1);
relationsButton.setSelected(true);
} else if(target.getId() == R.id.providers_tab_btn){
//mTabHost.setCurrentTab(2);
providersButton.setSelected(true);
}
}
So I have added the tabHandler button and the xml is inflated inside the fragment main class but I get an error pressing any of the tab buttons:
java.lang.IllegalStateException: Could not find method tabHandler(View) in a parent or ancestor Context for android:onClick attribute
I am also not sure how I would update the tabcontent pane as all the examples seem to use an Activity and have the activity class extend from TabActivity but using a fragment my class already extends Fragment.
How do I get this to work with a fragment which contains the tabs?
The method that you've specified in android:onClick (tabHandler) should be located in the Activity, not the Fragment. This SO answer has more information: https://stackoverflow.com/a/4153842/3214339
I'm working on an android project and my fragment are not working...
I'm trying to have this kind of UI ->
http://developer.android.com/training/basics/fragments/fragment-ui.html
However my second fragment doesn't replace or hide the first one, it's simply going under it!
This is how I declare my first fragment in the main activity:
setContentView(R.layout.finallayout);
Bundle bundle = new Bundle();
bundle.putStringArrayList("urllist", URLlist);
// set Fragmentclass Arguments
MainFragment main = new MainFragment();
main.setArguments(bundle);
getFragmentManager().beginTransaction().add(R.id.scrollcontentcontainer, main,"list").commit();
In the onCreateView of this one, I'm adding some content:
mainview = inflater.inflate(R.layout.finallayout, container, false);
scollviewgroup= (ViewGroup) container.findViewById(R.id.scrollcontentcontainer);
//mainview.setOnClickListener(this);
for (int i = 0; i < json.size(); i++) {
lineartab.add(inflater.inflate(R.layout.relativeaqi, scollviewgroup, false));
createMainLayout(this.json.get(i), i, lineartab.get(i), scollviewgroup, inflater);
}
and that's the way I declare the second one:
Fragment contentFragment = new CoreFragment();
FragmentManager fm = getActivity().getFragmentManager();
FragmentTransaction fragmentTransaction = fm.beginTransaction();
// fragmentTransaction.add(contentFragment, "core");
fragmentTransaction.replace(R.id.scrollcontentcontainer, contentFragment);
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
On the onCreateView, I'm inflating with a layout contained in a other layout file:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
//container.removeAllViews();
//IF I USE THIS ONE I HAVE THE EXPECTED RESULT, HOWEVER I M NOT SURE THATS THE BEST WAY TO DO IT SINCE ITS REMOVING THE CONTENT INCLUDED IN THE OTHER FRAGMENT
View view = inflater.inflate(R.layout.placecore, container, false);
return view;
}
Trying to use add instead of replace, or using hide doesn't work.
I want my two fragments to use the same layout template, but with an unique instance of it for each fragment, I don't know if it's possible or not. I tried to use a different layout file for the second one but then I had always an error saying No view found for id...
Anyone know how to fix that? thanks
xml files:

Following Michael's comment, using the support library ('android.support.v4.app.Fragment') fixed my problem.
I am stuck, I dont get how to implement a ListView that is inside a Fragment, I am trying to make a chat gui.
Is it possible to do something like this or am I totaly out in the wind?
Thanks for help! Regards a newbie! ^^
Here is the Fragment code:
public static class ChatFragment extends Fragment {
public ChatFragment() {
// Empty constructor required for fragment subclasses
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_chat, container, false);
/*FragmentManager fm = getActivity().getFragmentManager();
DataListFragment list = new DataListFragment();
fm.beginTransaction().add(R.id.list_message_History, list).commit();
*/
getActivity().setTitle(R.string.chat);
return rootView;
}
}
But as u see I dont udnerstand how to connect it all. I have med a customized ListFragment that uses a ArrayAdapter to handle the data.
Here is my layout file:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#id/android:list"
android:orientation="horizontal">
<ListView android:id="#android:id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:drawSelectorOnTop="false"/>
</LinearLayout>
<LinearLayout 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"
android:orientation="horizontal">
<EditText android:id="#+id/edit_message"
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:hint="#string/edit_message" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/button_send" />
</LinearLayout>
</LinearLayout>
You don't have to add another Fragment inside your ChatFragment to just have a ListView. Get a reference for the ListView out of your layout like this:
ListView list = (ListView)rootView.findViewById(R.id.list);
Now set the adapter and the Array/List to it and you're done.
And don't make a Fragment transaction inside a Fragment. Use your Activity and the DrawerLayout for this job.
No need of ChatFragment
Make you activity a FragmentActivity and directly inflate the layout(R.layout.fragment_chat) with the ListFragment in that Activity.
class MainActivity extends FragmentActivity {
onCreate(Bundle extra) {
...
setContentView(R.layout.fragment_chat);
...
}
}
Check this example for using ListFragments.
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;
import android.support.v4.app.FragmentTabHost;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

// R.layout.fragment_tabs_pager contains the layout as specified in your question

for (String subItem : itemsToBeDisplayed) {
// Give along the name - you can use this to hand over an ID for example
Bundle b = new Bundle();
b.putString("TAB_ITEM_NAME", subItem);
// Add a tab to the tabHost
mTabHost.addTab(mTabHost.newTabSpec(subItem).setIndicator(subItem), YourContentFragment.class, b);
}
return rootView;
}
}

// Do something with that string
}
}
}
}
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 {

# 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!
