ViewPager not showing page content / not refreshing after changing the view

I am using ViewPager / FragmentPagerAdapter in one of my application fragments to display different listviews in each page (see the picture below) :
The problem is that after i change the current view (Fragment) and i reopen it again, the listview isn't rendered (see the picture below) :
The behaviour is random, sometimes the listview are shown when i slide between different tabs/pages.
Here is my fragment code :
public class AstucesFragment extends Fragment implements ActionBar.TabListener {
ActionBar actionBar;
AppSectionsPagerAdapter mAppSectionsPagerAdapter;
ViewPager mViewPager;
public static String[] tabslist = new String[5];
public AstucesFragment() {
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_astuces, container, false);
tabslist[0] = getActivity().getResources().getString(R.string.astuces_quotidien);
tabslist[1] = getActivity().getResources().getString(R.string.astuces_resto);
tabslist[2] = getActivity().getResources().getString(R.string.astuces_loisirs);
tabslist[3] = getActivity().getResources().getString(R.string.astuces_transports);
tabslist[4] = getActivity().getResources().getString(R.string.astuces_tous);
mAppSectionsPagerAdapter = new AppSectionsPagerAdapter(getActivity().getSupportFragmentManager());
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
mViewPager = (ViewPager) view.findViewById(R.id.astuces_pager);
mViewPager.setAdapter(mAppSectionsPagerAdapter);
mViewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {
#Override
public void onPageSelected(int position) {
actionBar.setSelectedNavigationItem(position);
}
});
actionBar.addTab(
actionBar.newTab()

How can i fix this problem ?

If you want your fragments to maintain its state even after changing the tabs,
Try this,
mViewPager.setOffscreenPageLimit(5); //as you have 5 fragments
But this will make the activity to initialize all the fragments at the same time when the activity is invoked.
Another method is to use FragmentStatePagerAdapter instead of FragmentPagerAdapter. Refer,
http://developer.android.com/reference/android/support/v4/app/FragmentStatePagerAdapter.html

You are not comparing strings correctly. When comparing two strings you need to use equals() method instead of == operator. So in onCreateView() in AstucesListFragment replace
if (args.getString(ARG_PAGE_CAT) == getString(R.string.astuces_quotidien)) theme = "Q";
else if (args.getString(ARG_PAGE_CAT) == getString(R.string.astuces_resto)) theme = "R";
else if (args.getString(ARG_PAGE_CAT) == getString(R.string.astuces_loisirs)) theme = "L";
else if (args.getString(ARG_PAGE_CAT) == getString(R.string.astuces_transports)) theme = "T";
else theme = "";
with
if (args.getString(ARG_PAGE_CAT).equals(getString(R.string.astuces_quotidien))) theme = "Q";
else if (args.getString(ARG_PAGE_CAT).equals( getString(R.string.astuces_resto))) theme = "R";
else if (args.getString(ARG_PAGE_CAT).equals( getString(R.string.astuces_loisirs))) theme = "L";
else if (args.getString(ARG_PAGE_CAT).equals( getString(R.string.astuces_transports))) theme = "T";
else theme = "";
This may solve your problem as the results of == operators will be inconsistent as both the strings may or may not point to same object.

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));
}
}
}

I think you already got the answer, that's why you developed this:
https://stackoverflow.com/questions/19000981/actionbarsherlock-swapping-tabs-using-viewpager
Anyways if you still looking for answer, So
I really recommend you to use ActionBarStyleGenerator:
http://jgilfelt.github.io/android-actionbarstylegenerator/
With that tool you can easily theme your graphic elements in your toolbar.

use this for QA:2,3,4
create xml(tab1) in drawble folder
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- When selected, use grey -->
<item android:drawable="#drawable/videos_gray"
android:state_selected="true" />
<!-- When not selected, use white-->
<item android:drawable="#drawable/videos_white" />
and use that in java file
// Create an actionbar
ActionBar actionBar = getActionBar();
// Hide Actionbar Icon
actionBar.setDisplayShowHomeEnabled(false);
// Hide Actionbar Title
actionBar.setDisplayShowTitleEnabled(false);
// Create Actionbar Tabs
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
// Create first Tab
tab = actionBar.newTab().setTabListener(new FragmentTab1());
// Create your own custom icon
tab.setIcon(R.drawable.tab1);
actionBar.addTab(tab);
// Create Second Tab
tab = actionBar.newTab().setTabListener(new FragmentTab2());
// Set Tab Title
tab.setText("Tab2");
actionBar.addTab(tab);
// Create Third Tab
tab = actionBar.newTab().setTabListener(new FragmentTab3());
// Set Tab Title
tab.setText("Tab3");
actionBar.addTab(tab);

Ans for Q.1 :
You can make a new layout and set its Height at desired "dp" and change the background of that layout to Red color (use resource for that - preferably define a color using color code OR bring in image with Red background). This does not involve using fragments.
Ans for Q.5:
If you use my option as above, use RelatieLayout for Title bar. Then position the button you want at the rightmost side.(Use gravity or manually drag or android:layout_alignParentRight="true" - whichever way you want)
Can't say anything about other questions. Hope this helps

ListFragments inside ViewPager

I'm writing my first fragment-based app and running into some heavy problems which i couldn't solve with the API or Stackoverflow.
I am using a viewPager to swipe between two lists. Each list has a header button to create a new list element (similar to the native android alarm app). The button returns currently an error message for debugging.
The problem is:
FragmentList A returns the debug message for FragmentList B
FragmentList B returns no debug message
... // The main class
public class DemoApp extends FragmentActivity implements ActionBar.TabListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// Set up the action bar.
final ActionBar actionBar = getActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
PageAdapter mPageAdapter = new PageAdapter(getSupportFragmentManager());
mViewPager = (ViewPager) findViewById(R.id.pager);
mViewPager.setAdapter(mPageAdapter);
mViewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {
#Override
public void onPageSelected(int position) {
actionBar.setSelectedNavigationItem(position);
}
});
for (int i = 0; i < mPageAdapter.getCount(); i++) {
actionBar.addTab(actionBar.newTab().setText(mPageAdapter.getPageTitle(i)).setTabListener(this));
}
}
...
My custom PageAdapter will create two list framgent objects:
public class PageAdapter extends FragmentStatePagerAdapter {
private final int NUMBER_PAGES = 2;
public PageAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
if (position == 0) {
return new FoodListFragment();
} else if (position == 1){
return new LocationListFragment();
} else {
throw new IllegalArgumentException("Invalid page position: " + position);
}
}
#Override
public int getCount() {
return NUMBER_PAGES;
}
...
}
FoodListFragment snipped (The other list looks similar except the debug output) :
public class FoodListFragment extends ListFragment implements LoaderCallbacks<Cursor> {
/*
* (non-Javadoc)
*
* #see android.support.v4.app.Fragment#onActivityCreated(android.os.Bundle)
*/
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
// add a list header with the button to create a new list item
View v = getActivity().getLayoutInflater().inflate(R.layout.list_header, null);
getListView().addHeaderView(v);
...
setListAdapter(getSomeAdapter());
// get the list header button
ImageButton createItem = (ImageButton) getActivity().findViewById(R.id.create_new_entry);
createItem.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.e(LOG_TAG, "onclick FoodListFragment");
}
});
}
main.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/wrapper"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<android.support.v4.view.ViewPager
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/pager"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
tools:context=".DemoApp" />
</LinearLayout>

I've found the bug. In each list i was calling the same header view and same header button. The onClick method could not be clearly assigned

(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" />
</LinearLayout>
here is the code for MainActivity.java I'll post relevant code only so you'll have to manage it
public class MainActivity extends FragmentActivity implements
DialogInterface.OnDismissListener, TabDataResponder {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

}
}

}
}
#Override
public void onDismiss(DialogInterface dialog) {

}
//This interface must be call from fragment class
//# the time of event you want to show detail
// pass the class name in the type argument using class.getName() method
#Override
public void loadData(String type, int index) {
DetailFragment viewer = (DetailFragment) getSupportFragmentManager()
.findFragmentById(R.id.fragment_details);
if (mDualPane) {
if (viewer == null || viewer.getShownIndex() != index
|| viewer.getTypeFragment() != type) {
DetailFragment df = DetailFragment.newInstance(index, type);
getSupportFragmentManager()
.beginTransaction()
.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.
