I want to add fragments to each corresponding actionbar tab at the same time

UPDATE : I don't understand why when tapping on each tab onTabSelected() doesn't show the correct fragment even though it's been added to the fragmentTransaction android.R.id.content.
I call this method before onTabSelected gets called to make sure fragments are not null.
protected void initTabs() {
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
if(mShowFragment3 == null) {
mShowFragment3 = EpisodeTileFragment.newInstance(getString(R.string.title_section4));
ft.add(android.R.id.content, mShowFragment3);
}
if(mShowFragment2 == null) {
mShowFragment2 = EpisodeTileFragment.newInstance(getString(R.string.title_section3));
ft.add(android.R.id.content, mShowFragment2);
}
}
#Override
public void onTabSelected(ActionBar.Tab tab,
FragmentTransaction ft) {
//this usually works, but if i try to mess with adding the tabs to the
//FragmentTransaction this won't work anymore
if(tab.getPosition() == 1) {
ft.show(mShowFragment2);
}
I have scoured the internet and this may not be possible but I wanted to give this a shot.
I currently have the app working fine, it has 4 tabs and 4 corresponding fragments. When a user opens the app onTabSelected is called and selects the first tab/fragment is added and we're all good.
A user clicks tab2 and the 2nd fragment is added and rendered. When a user clicks the 2nd tab there is an asynctask that gets data and renders this on a fragment. Etc.. this happens on tab 3 and 4 also. When a user clicks a tab the first time I instantiate the fragment and add it to the fragmentTransaction, the next time you click on the tab it's lightning fast because it's already added, and I'm hiding and showing fragments.
The question I have is , is there a way to load up all 4 tabs at the same time, vs. waiting for a user to click on a tab and then have onTabSelected firing and grabbing data etc. Please let me know if there is any questions, the code is working with no errors just not what I want, and I don't know how to instantiate all 4 fragments at the same time.
mSectionsPagerAdapter = new SectionsPagerAdapter(this.getSupportFragmentManager());
mViewPager = (ViewPager) findViewById(R.id.pager);
mViewPager.setAdapter(mSectionsPagerAdapter);
for (int i = 0; i < mSectionsPagerAdapter.getCount(); i++) {
LayoutInflater inflater = LayoutInflater.from(getApplicationContext());
View tabView = inflater.inflate(R.layout.tab_title, null);
TextView titleTV = (TextView) tabView.findViewById(R.id.action_custom_title);
titleTV.setText(mSectionsPagerAdapter.getPageTitle(i));
titleTV.setTypeface(Typeface.createFromAsset(getAssets(), getString(R.string.tab_font)));
titleTV.setSingleLine();
titleTV.setTextSize(13);
Tab t = actionBar.newTab()
.setText(mSectionsPagerAdapter.getPageTitle(i))
.setTabListener(this);
t.setCustomView(tabView);
actionBar.addTab(t);
}
this is for adding the tabs. but need to add the fragments for each tab.

Set the offscreen page limit to your number of tabs, and then your ViewPager will render all the fragments when the parent activity is created.
mViewPager.setOffscreenPageLimit(4);
You should also check out the Class Overview of ViewPager, which has a really good example of using a custom FragmentPagerAdapter called TabsAdapter with a ViewPager (instead of using the ADT generated SectionsPagerAdapter). I added the code from the official Android docs below:
public class ActionBarTabsPager extends Activity {
ViewPager mViewPager;
TabsAdapter mTabsAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mViewPager = new ViewPager(this);
mViewPager.setId(R.id.pager);
setContentView(mViewPager);
final ActionBar bar = getActionBar();
bar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
bar.setDisplayOptions(0, ActionBar.DISPLAY_SHOW_TITLE);
mTabsAdapter = new TabsAdapter(this, mViewPager);
mTabsAdapter.addTab(bar.newTab().setText("Simple"),
CountingFragment.class, null);
mTabsAdapter.addTab(bar.newTab().setText("List"),
FragmentPagerSupport.ArrayListFragment.class, null);
mTabsAdapter.addTab(bar.newTab().setText("Cursor"),
CursorFragment.class, null);
if (savedInstanceState != null) {
bar.setSelectedNavigationItem(savedInstanceState.getInt("tab", 0));
}
}
#Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putInt("tab", getActionBar().getSelectedNavigationIndex());
}
/**
* This is a helper class that implements the management of tabs and all
* details of connecting a ViewPager with associated TabHost. It relies on a
* trick. Normally a tab host has a simple API for supplying a View or
* Intent that each tab will show. This is not sufficient for switching
* between pages. So instead we make the content part of the tab host
* 0dp high (it is not shown) and the TabsAdapter supplies its own dummy
* view to show as the tab content. It listens to changes in tabs, and takes
* care of switch to the correct paged in the ViewPager whenever the selected
* tab changes.

ActionBar Tabs are not displayed

I'm implementing ActionBar tabs according to official guide.
I have a fragment that is added to activity. In that fragment I'm creating tabs:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ActionBar actionBar = getActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
actionBar.setDisplayShowTitleEnabled(false);
Tab tab = actionBar.newTab()
.setText("One")
.setTabListener(new TabListener<DemoFragment>(
this, "1", DemoFragment.class));
actionBar.addTab(tab);
tab = actionBar.newTab()
.setText("Two")
.setTabListener(new TabListener<DemoFragment>(
this, "2", DemoFragment.class));
actionBar.addTab(tab);
}
But these tabs are never displayed. Nor content of DemoFragment. Even though at runtime getActionBar().getTabCount() returns correct count of tabs. And I see that DemoFragment is initialized. All I see is ActionBar.
What am I doing wrong?
I'm not using any support libraries as I'm developing for minSdk=14.

Update
IF YOUR NOT USING ANY SUPPORT LIBRARY THIS SHOULD WORK
otherwise you will have to use the getSupportActionBar() and above mentioned dependencies.
Try something more like this:
// Get the Instance of the Action Bar, set Navigation Mode, remove title
ActionBar actionBar = getActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
actionBar.setDisplayShowTitleEnabled(false);
// One tab
actionBar.addTab(actionBar.newTab() .setText("One")
.setTabListener(new TabListener<DemoFragment>(
this, "1", DemoFragment.class)));
// Two tab
actionBar.addTab(actionBar.newTab()
.setText("Two")
.setTabListener(new TabListener<DemoFragment>(
this, "2", DemoFragment.class)));
Edit to Post - Working Code that I have used for a demo
Here is code from a demo Application That i wrote using Android sdk 14 Just like you are.
public class MainActivity extends Activity {
// String Titles
static String [] titles = {"Fragment 1", "Fragment 2"};
static String [] fragmentClasses = {Fragment1.class.getName(), Fragment2.class.getName()};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
SimpleTabListener.SetUpTabNavigation(this, fragmentClasses, titles);
}
And here is the SimpleTabListener Class
public class SimpleTabListener implements TabListener {
Context m_context;
String m_fragmentClassName ;
Fragment m_fragment = null;
public SimpleTabListener(Context context, String tabFragmentClassName)
{
m_context = context;
m_fragmentClassName = tabFragmentClassName;
}
#Override
public void onTabReselected(ActionBar.Tab tab, FragmentTransaction ft)
{
// TODO Auto-generated method stub
}
#Override
public void onTabSelected(ActionBar.Tab tab, FragmentTransaction ft)
{
if(m_fragment == null)
{
m_fragment = Fragment.instantiate(m_context, m_fragmentClassName);
ft.add(android.R.id.content, m_fragment);
}else
{
ft.attach(m_fragment);
}
}
#Override
public void onTabUnselected(ActionBar.Tab tab, FragmentTransaction ft)
{
// TODO Auto-generated method stub
if(m_fragment != null){
// TODO Auto-generated method stub
ft.detach(m_fragment);
}
}
public static void SetUpTabNavigation(Activity activity, String [] classNames, String [] tabTitles){
ActionBar actionBar = activity.getActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
ActionBar.TabListener listener;
for(int i = 0; i < tabTitles.length; i++)
{
listener = new SimpleTabListener(activity, classNames[i]);
actionBar.addTab(actionBar.newTab().setText(tabTitles[i]).setTabListener(listener));
}
}
}

How to use SherlockFragmentActivity with SlidingMenu?

Am using SlidingMenu which uses different types of Fragment/SherlockFragment as menu.
Am in need of SherlockFragmentActivity, as I am using Tabs inside menu.
How to use SherlockFragmentActivity with SlidingMenu?
If it's not possible, is there any other library through which I can have sliding menu & tabs inside sliding menu? Am not sure if it can be achieved using android-menudrawer
Edit : want to achieve the below. ie, Tabs inside Menu
when menu button is clicked, menu Fragment is opened, inside Menufragment I want to add tabs.
   

EDIT:
I wanted to take this design as a challenge and see what is the result:
As I suggested in the comments, I used PagerSlidingTabStrip andViewPager.
I did not include the ActionBarSherlock, but if needed that will be easy to modify: the MainActivity will be required to extend from SherlockFragmentActivity, and the theme #style/Theme.Sherlock.Light added to manifest file, and that is all.
(Just to be sure you got the idea, PagerSlidingTabStrip is the one who creates the tabs at the bottom)
Here are the steps I took to integrate PagerSlidingTabStrip and ViewPager with SlidingMenu:
1 - Import SlidingMenu library into Eclipse workspace
2 - Import PagerSlidingTabStrip library into Eclipse workspace
3 - Add Android Support Library to your project (and copy the same .jar into SlidingMenu and PagerSlidingTabString libraries, otherwise eclipse might complain)
4 - A minimal example of MainActivity:
public class MainActivity extends FragmentActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
SlidingMenu menu = new SlidingMenu(this);
menu.setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN);
menu.setBehindOffset(50);
menu.setFadeDegree(0.35f);
menu.attachToActivity(this, SlidingMenu.SLIDING_CONTENT);
menu.setMenu(R.layout.left_menu);
ViewPager pager = (ViewPager) findViewById(R.id.pager);
pager.setAdapter(new ViewPagerAdapter(getSupportFragmentManager()));
PagerSlidingTabStrip tabs = (PagerSlidingTabStrip) findViewById(R.id.tabs);
tabs.setViewPager(pager);
}
}
5 - The layout of sliding menu, R.layout.left_menu:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/left_menu"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#CCC"
android:orientation="vertical" xmlns:app="http://schemas.android.com/apk/res/org.grec">
<com.astuetz.viewpager.extensions.PagerSlidingTabStrip
android:id="#+id/tabs"
app:shouldExpand="true"
android:layout_width="match_parent"
android:layout_alignParentBottom="true"
android:layout_height="48dip" />
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#id/tabs" />
</RelativeLayout>
6 - The ViewPagerAdapter:
public class ViewPagerAdapter extends FragmentStatePagerAdapter {
private final int PAGES = 3;
private String[] titles={"Tab 1", "Tab 2", "Tab 3"};
public ViewPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
switch (position) {
case 0:
return new TabFragment1();
case 1:
return new TabFragment2();
case 2:
return new TabFragment3();
default:
throw new IllegalArgumentException("The item position should be less or equal to:" + PAGES);
}
}
#Override
public CharSequence getPageTitle(int position) {
return titles[position];
}
#Override
public int getCount() {
return PAGES;
}
}
7 - And an example of fragment, TabFragment1.java (the other 2 are similar):
public class TabFragment1 extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_tab_1, container, false);
}
}
8 - And the layout of the fragment R.layout.fragment_tab_1 which is pretty simple, it contains a single TextView, so I won't include it here.
I hope this example addresses your issue and will help you getting started on the right track.

1) Add SherlockActionBar library to SlidingMenu
2) Change SlidingFragmentActivity extends FragmentActivity to SlidingFragmentActivity extends SherlockFragmentActivity
3) Then add SlidingMenu library to your project and your project should use MyProjectActivity extends SlidingFragmentActivity
You can use SherlockActionBar to create sliding menu with tabs inside
Here sample code to create Tab with view pager
For sliding, you can look at their documentation
public static class TabsAdapter extends FragmentPagerAdapter implements ActionBar.TabListener, ViewPager.OnPageChangeListener {
private final Context mContext;
private final ActionBar mActionBar;
private final ViewPager mViewPager;
private final ArrayList<TabInfo> mTabs = new ArrayList<TabInfo>();
static final class TabInfo {
private final Class<?> clss;
private final Bundle args;
TabInfo(Class<?> _class, Bundle _args) {
clss = _class;
args = _args;
}
}
public TabsAdapter(SherlockFragmentActivity activity, ViewPager pager) {
super(activity.getSupportFragmentManager());
mContext = activity;
mActionBar = activity.getSupportActionBar();
mViewPager = pager;
mViewPager.setAdapter(this);
mViewPager.setOnPageChangeListener(this);
}
public void addTab(ActionBar.Tab tab, Class<?> clss, Bundle args) {
TabInfo info = new TabInfo(clss, args);
tab.setTag(info);
tab.setTabListener(this);
mTabs.add(info);
mActionBar.addTab(tab);
notifyDataSetChanged();
}
#Override
public int getCount() {
return mTabs.size();
}
#Override
public Fragment getItem(int position) {
TabInfo info = mTabs.get(position);
return Fragment.instantiate(mContext, info.clss.getName(), info.args);
}
#Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
}
#Override
public void onPageSelected(int position) {
mActionBar.setSelectedNavigationItem(position);
}
#Override
public void onPageScrollStateChanged(int state) {
}
public void onTabSelected(Tab tab, FragmentTransaction ft) {
Object tag = tab.getTag();
for (int i = 0; i < mTabs.size(); i++) {
if (mTabs.get(i) == tag) {
mViewPager.setCurrentItem(i);
}
}
}
#Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
}
#Override
public void onTabReselected(Tab tab, FragmentTransaction ft) {
}
}
mViewPager = new ViewPager(this);
mViewPager.setId(R.id.pager);
setContentView(mViewPager);
ab.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
mTabsAdapter = new TabsAdapter(this, mViewPager);
mTabsAdapter.addTab(ab.newTab().setText("tab1"), FirstFragment.class, null);
mTabsAdapter.addTab(ab.newTab().setText("tab2"), SecondFragment.class, null);
mTabsAdapter.addTab(ab.newTab().setText("tab3"), ThirdFragment.class, null);

As what you have said the SlidingMenu uses fragments and you want to to have Tabs inside a Menu. For me, using Tabs inside a Menu needs nested fragments which means that you can't use SherlockFragmentActivity since it is like the Main Activity. You can't contain an Activity inside a fragment.
I have not implemented this kind of approach but maybe you can try implementing TabListener inside a fragment.
I am using this code for my activity not the fragment,
class MainActivity extends SherlockFragmentActivity implements ActionBar.TabListener
{
}
maybe you can have,
class FragmentA extends SherlockFragment implements TabListener{
#Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
// TODO Auto-generated method stub
}
#Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
// TODO Auto-generated method stub
}
#Override
public void onTabReselected(Tab tab, FragmentTransaction ft) {
// TODO Auto-generated method stub
}
}

EditText field displaying data on different tabs

I'm having some pretty strange issues with my app. I have an EditText element, lets call it display, in a reused fragment for each tab. Every time I launch the app I see the following initial behaviour when I click a button that sends text to the output display. I do not use the system keyboard, only my buttons send to the display.
The best way to think of this is like a web browser with tabs, you can edit the URL in each tab independently, and the buttons, that live below in the other two sections, supply the input. It's not a web browser, but the analogy works.
Don't click on anything -> Text drawn in B tab
Click on B -> Text drawn in C tab
Click on C -> Text drawn in C tab
Click on B -> Click on C -> App Crashes
I might be running into a fencepost error but I'm not sure. I can get text to draw in A's output but only after a click or two.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.container);
midPager = (ViewPager) findViewById(R.id.function_container);
topPager = (ViewPager) findViewById(R.id.top_container);
midPagerAdapter = new midPageAdapter(getFragmentManager());
midPager.setAdapter(midPagerAdapter);
final ActionBar actionBar = getActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
actionBar.setDisplayOptions(0, ActionBar.DISPLAY_SHOW_TITLE);
TabsAdapter topTabsAdapter = new TabsAdapter(this,topPager);
topTabsAdapter.addTab(actionBar.newTab().setText("1"),
TopFragment.class, null);
topTabsAdapter.addTab(actionBar.newTab().setText("2"),
TopFragment.class, null);
topTabsAdapter.addTab(actionBar.newTab().setText("3"),
TopFragment.class, null);
if (savedInstanceState != null) {
actionBar.setSelectedNavigationItem(savedInstanceState.getInt("tab",0));
}
}
And in my function that manages the tabs this is what I have:
public static class TabsAdapter extends FragmentPagerAdapter
implements ActionBar.TabListener, ViewPager.OnPageChangeListener {
private final Context mContext;
private final ActionBar mActionBar;
private final ViewPager mViewPager;
private final ArrayList<TabInfo> mTabs = new ArrayList<TabInfo>();
static final class TabInfo {
private final Class<?> clss;
private final Bundle args;
TabInfo(Class<?> _class, Bundle _args) {
clss = _class;
args = _args;
}
}
public TabsAdapter(Activity activity, ViewPager pager) {
super(activity.getFragmentManager());
mContext = activity;
mActionBar = activity.getActionBar();
mViewPager = pager;
mViewPager.setAdapter(this);
mViewPager.setOnPageChangeListener(this);
}
public void addTab(ActionBar.Tab tab, Class<?> clss, Bundle args) {
TabInfo info = new TabInfo(clss, args);
tab.setTag(info);
tab.setTabListener(this);
mTabs.add(info);
mActionBar.addTab(tab);
notifyDataSetChanged();
}
#Override
public int getCount() {
return mTabs.size();
}
#Override
public Fragment getItem(int position) {
TabInfo info = mTabs.get(position);
return Fragment.instantiate(mContext, info.clss.getName(), info.args);
}
#Override
public void onPageScrolled(int position, float positionOffset,
int positionOffsetPixels) {
}
#Override
public void onPageSelected(int position) {
mActionBar.setSelectedNavigationItem(position);
}
#Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
Object tag = tab.getTag();
for (int i = 0; i < mTabs.size(); i++)
{
if (mTabs.get(i) == tag)
{
setActiveMap(i);
mViewPager.setCurrentItem(i);
}
}
}
}
In my reusable fragment I have this for my OnCreate function.
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.top_fragment, container, false);
Foobar active = Container.getActiveMap();
active.editLine = (EditText) v.findViewById(R.id.display);
active.editLine.setCursorVisible(false);
active.editLine.addTextChangedListener((TextWatcher) this);
((EditText) v.findViewById(R.id.display)).setOnClickListener(this);
return v;
}
One question that would help me debug this is how can I debug EditText within a reused fragment in tabs? What data does an EditText widget use to distinguish itself from tab to tab? I've tried various .tostring()'s of functions without success.
The more ideal solution is a simple error you spot in this code. Thanks for your help.
We could have 3 separate fragments but they all are of the same configuration however that seems unnecessarily ugly.

(ActionBar) Tabs + Pager + detail Fragments inside ViewPager container

For ActionBarSherlock I would like to have (Action Bar) Tabs + Pager. I use Fragments inside that pager container. I already got the examples of http://actionbarsherlock.com/ working, but I can't manage to get a details fragment inside that pager container when I would click on let's say a listitem in the first fragment.
Is it impossible to have something like this:
Activity with Tabs and pager container
Fragment A inside pager container under Tab1
Click on something in Fragment A and show Fragment B in same pager container under Tab1.
Fragment A is then not visible, only Fragment B is visible, but also all the Tabs.
At the moment I think only a new activity (which would hold Fragment B inside it) can be started after clicking something in Fragment A.

Here is my solution for the (Tabs + Fragment + ViewPager) it is works for me as i wanted,
hope that works for you as well
here is the xml file
<LinearLayout
android:id="#+id/linearLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="0dip"
android:layout_height="match_parent"
android:layout_weight="5" />
<FrameLayout
android:id="#+id/fragment_details"
android:layout_width="0px"
android:layout_height="match_parent"
android:layout_weight="4.3" />

.replace(R.id.fragment_details, df)
.setTransition(
FragmentTransaction.TRANSIT_FRAGMENT_FADE)
.commit();
map.put(type.trim(), index);
}
} else {
Intent intent = new Intent();
intent.setClass(MainActivity.this, DetailActivity.class);
intent.putExtra("index", index);
intent.putExtra("type", type);
startActivity(intent);
}
}
}
and here is how i deal with detail fragment not very efficient but kind of working
public class DetailFragment extends Fragment{
public static DetailFragment newInstance(int index, String TYPE_FRAGMENT) {
DetailFragment f = new DetailFragment();
// Supply index input as an argument.
Bundle args = new Bundle();
args.putInt("index", index);
args.putString("type", TYPE_FRAGMENT);
f.setArguments(args);
return f;
}
public int getShownIndex() {
return getArguments().getInt("index", 0);
}
public String getTypeFragment(){
String a = getArguments().getString("type");
return a;
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
//template is blank layout
View view = inflater.inflate(R.layout.template, container, false);
if(getTypeFragment().equals(ArtistFragment.TYPE_FRAGMENT)){
view = null;
view = inflater.inflate(R.layout.artist_details, container, false);
//....
}
else if(getTypeFragment().equals(AlbumFragment.TYPE_FRAGMENT)){
//do's for album fragment
}
else if(getTypeFragment().equals(SongFragment.TYPE_FRAGMENT)){
//do's for song fragment
}
return view;
}
}
do not save the state of tab in their individual fragment it will conflict, we are already doing it here

EDIT:
Cheered too soon. Now the details_container is not a viewpager and I cannot use it to 'swipe tabs'.
Found it! Just had to define two FrameLayouts, with in the first one the ViewPager and in the second the details fragments can be 'loaded'. This is done by adding fragments dynamically and replace them.
First the two FrameLayouts:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fadingEdge="none" >
<FrameLayout
android:id="#+id/main_container"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</FrameLayout>
<FrameLayout
android:id="#+id/details_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
Then replace a fragment dynamically:
// Create new fragment and transaction
Fragment detailsFragment = new ExampleFragment();
FragmentTransaction transaction = getFragmentManager().beginTransaction();
// Replace whatever is in the fragment container view with this fragment
// and add the transaction to the back stack
transaction.replace(R.id.details_container, detailsFragment);
transaction.addToBackStack(null);
// Commit the transaction
transaction.commit();
Very simple and I don't understand why it took me hours to figure this out..

I still did not find a possibility to have a Pager container where fragments should be loaded in and also keep the (ActionBar) Tabs. I have however found a really dirty solution to acomplish this, with starting intens (Main Activity with the Tabs) and finishing the previous ones when the backbutton doesn't need it anymore.
I adapted the code from ABS: Support Demos - Tabs and Pager. But again it's really dirty:
LoaderCursorSupport.CursorLoaderListFragment under Tab2
#Override public void onListItemClick(ListView l, View v, int position, long id) {
Intent intent = new Intent();
intent.setClass(getActivity(), ActionBarTabsPager.class);
intent.putExtra("index", position);
intent.putExtra("fragment", "details");
intent.putExtra("tab", 1);
ActionBarTabsPager.mPreviousActivity = getActivity();
startActivity(intent);
ActionBarTabsPager (Main Activity with Tabs)
public class ActionBarTabsPager extends FragmentActivity {
ViewPager mViewPager;
TabsAdapter mTabsAdapter;
static Activity mPreviousActivity;
static Activity mActivity;
static int mTabPosition = -1;
static Boolean mTabRefreshed = false;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.actionbar_tabs_pager);
getSupportActionBar().setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
ActionBar.Tab tab1 = getSupportActionBar().newTab().setText("Tab 1");
ActionBar.Tab tab2 = getSupportActionBar().newTab().setText("Tab 2");
ActionBar.Tab tab3 = getSupportActionBar().newTab().setText("Tab 3");
ActionBar.Tab tab4 = getSupportActionBar().newTab().setText("Tab 4");
String fragment = "";
try {
Bundle bundle = this.getIntent().getExtras();
fragment = bundle.getString("fragment");
mTabPosition = bundle.getInt("tab");
} catch (Exception ex) {
}
mViewPager = (ViewPager) findViewById(R.id.pager);
mTabsAdapter = new TabsAdapter(this, getSupportActionBar(), mViewPager);
mTabsAdapter.addTab(tab1, FragmentStackSupport.CountingFragment.class);
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.ECLAIR) {
mTabsAdapter.addTab(tab2, FragmentStackSupport.CountingFragment.class);
mTabsAdapter.addTab(tab3, FragmentStackSupport.CountingFragment.class);
mTabsAdapter.addTab(tab4, FragmentStackSupport.CountingFragment.class);
} else {
if (!fragment.contains("details")) {
mTabsAdapter.addTab(tab2, LoaderCursorSupport.CursorLoaderListFragment.class);
} else {
mTabsAdapter.addTab(tab2, ExampleFragment.class);
}
mTabsAdapter.addTab(tab3, LoaderCustomSupport.AppListFragment.class);
mTabsAdapter.addTab(tab4, LoaderThrottleSupport.ThrottledLoaderListFragment.class);
}
if (savedInstanceState != null) {
getSupportActionBar().setSelectedNavigationItem(savedInstanceState.getInt("index"));
}
if (mTabPosition > -1) {
mTabsAdapter.setPrimaryItem(mTabPosition);
mActivity = this;
}
}
Inside this Class there's a TabsAdapter
public static class TabsAdapter extends FragmentPagerAdapter implements ViewPager.OnPageChangeListener, ActionBar.TabListener {
private final Context mContext;
private final ActionBar mActionBar;
private final ViewPager mViewPager;
private final ArrayList<String> mTabs = new ArrayList<String>();
#Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
if (mTabPosition > -1 && mTabRefreshed) {
int tabPosition = tab.getPosition();
if (mTabPosition != tabPosition) {
if (mPreviousActivity != null) {
mPreviousActivity.finish();
mTabRefreshed = false;
mPreviousActivity = null;
mTabPosition = -1;
Intent intent = new Intent();
intent.setClass(mContext, ActionBarTabsPager.class);
intent.putExtra("fragment", "home");
intent.putExtra("tab", tabPosition);
mActivity.startActivity(intent);
mActivity.finish();
}
}
}
mViewPager.setCurrentItem(tab.getPosition());
}
Can this be done simpler? Or should I just give up on having Tabs together with fragment history? This was done before Android 3.0 with ActivityGroups and Activities, but it seems this can't be done with fragments.

I found the other good example of the same implementation in hear... https://github.com/UweTrottmann/SeriesGuide
In this example under package com.battlelancer.seriesguide.ui
you can find UpcomingRecentActivity.java, and UpcomingFragment.java
and layout upcoming_multipan.xml
this example works for me...
I got one problem while adding different content for detail-fragment the different tabs, it gives me class-cast-exception
so i implemented a common detalFragment class and created separate layout in onCreateView method
but the only one problem i found is layout is not changing on tab switched, may be need to do it by implementing some listener
I'll tell you when i found the answer.
