I succeeded in make a Tabbed Layout, but I have a concern. tabs appear but disappear just after loading the first fragment. i dont have lot of idea it is due to what. This the code to try to find the error.
The onCreateView of the fragment which on i display the cotaint.
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View v = inflater.inflate(R.layout.fragment_clubs_pages, container, false);

viewPager = (ViewPager) v.findViewById(R.id.pager);
actionBar = getActivity().getActionBar();
mAdapter = new TabsPagerAdapter(getChildFragmentManager());
viewPager.setAdapter(mAdapter);
actionBar.setHomeButtonEnabled(false);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_LIST);

I said that the tabs disappear just after loading the first fragment. so any help please ?

when i run this code,the toast in two different fragments are displayed on one tab. when i swipe to next tab nothing is displayed.
this is is my main tab activity:

viewPager.setCurrentItem(tab.getPosition());
}
#Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
}
}
this is adapter class :
public class TabsPagerAdapter extends FragmentStatePagerAdapter {
Bundle bundle = new Bundle();
public TabsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int index) {
switch (index) {

this is my first fragment :
public class OfferFragment extends Fragment {

// public static final String ARG_OBJECT = "object";
View rootView = inflater.inflate(R.layout.offerfragment, container,

txtview.setText(args.getString("OfferFragment"));
display();
return rootView;
}
private void display() {
// TODO Auto-generated method stub
Toast.makeText(getActivity(), name, Toast.LENGTH_SHORT).show();
}
}
this is my second fragment :
public class DistanceFragment extends Fragment {
private String name;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.distancefragment, container, false);
Bundle args = getArguments();

display();
return rootView;
}
private void display() {
// TODO Auto-generated method stub
Toast.makeText(getActivity(), name, Toast.LENGTH_SHORT).show();
}
}
any suggestions are appreciated. am stuck with this.
This is because next fragment is created by pager
before showing toast check if that fragment is visible or not
if(fragmentName.this.isVisible())
{
// do your stuff here
}
Write onResume() in every fragment class.
#Override
public void setUserVisibleHint(boolean isVisibleToUser) {
super.setUserVisibleHint(isVisibleToUser);
if (isVisibleToUser) {
//Display Toast message here
}
}
I have an ActionBar that contains 11 tabs and 1 fragment. I also have a ViewPager to display the fragment(s). When a tab is clicked it creates the same fragment. The tabs display dates so they change everyday. What I need is to send the text of the tab (ie. .getTabText()) to the fragment, this will change the content of the fragment. I am having so much trouble trying to figure out how to do this. Here is all my code:
public class MainActivity extends FragmentActivity implements
ActionBar.TabListener {
private ViewPager viewPager;
private TabsPagerAdapter mAdapter;
private ActionBar actionBar;
private ArrayList<TopRatedFragment> myFragmentList = new ArrayList<TopRatedFragment>();
// Tab titles
String[] tabs = {this.getCurrentDate(-5).toString(),this.getCurrentDate(-4).toString(),this.getCurrentDate(-3).toString(), this.getCurrentDate(-2).toString(),this.getCurrentDate(-1).toString(),
this.getCurrentDate(0).toString(),
this.getCurrentDate(1).toString(), this.getCurrentDate(2).toString(), this.getCurrentDate(3).toString(), this.getCurrentDate(4).toString(), this.getCurrentDate(5).toString(),};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
for (String tab_name : tabs) {
TopRatedFragment fm = new TopRatedFragment();
fm.getTabs(tab_name);
myFragmentList.add(fm);
}
viewPager = (ViewPager) findViewById(R.id.pager);
actionBar = getActionBar();
mAdapter = new TabsPagerAdapter(getSupportFragmentManager(), myFragmentList);
viewPager.setAdapter(mAdapter);
actionBar.setHomeButtonEnabled(false);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
// Adding Tabs
for (String tab_name : tabs) {
actionBar.addTab(actionBar.newTab().setText(tab_name)
.setTabListener(this));
}
actionBar.setSelectedNavigationItem(5);
/**
* on swiping the viewpager make respective tab selected
* */
viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
#Override
public void onPageSelected(int position) {
// on changing the page
// make respected tab selected
actionBar.setSelectedNavigationItem(position);
}
#Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
}
#Override
public void onPageScrollStateChanged(int arg0) {
}
});
}
public String getTab(Tab tab) {
return tab.getText().toString();
}
#Override
public void onTabReselected(Tab tab, FragmentTransaction ft) {
}
#Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
viewPager.setCurrentItem(tab.getPosition());
}
#Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
}
public String getCurrentDate(int offset) {
String calAsString;
DateFormat formatter = new SimpleDateFormat("MM/dd");
Calendar cal = Calendar.getInstance();
cal.add(Calendar.DATE, offset);
calAsString = formatter.format(cal.getTime());
return calAsString;
}
}
Here is my FragmentPagerAdapter:
public class TabsPagerAdapter extends FragmentPagerAdapter {
ArrayList<TopRatedFragment> myList;
public TabsPagerAdapter(FragmentManager fm, ArrayList<TopRatedFragment> myList) {
super(fm);
this.myList = myList;
}
#Override
public Fragment getItem(int index) {
return myList.get(index);
}
#Override
public int getCount() {
// get item count - equal to number of tabs
return myList.size();
}
And here is my simple fragment (for now):
public class TopRatedFragment extends Fragment {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
public void getTabs(String tabs) {
Log.e("TRF", tabs);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_top_rated, container, false);
return rootView;
}
}
Create a static newInstance method to create fragment and bundle the args for the fragment. Pull the args in the fragment.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
for (String tab_name : tabs) {
TopRatedFragment fm = new TopRatedFragment.newInstance(tab_name);
fm.getTabs(tab_name);
myFragmentList.add(fm);
}
public class TopRatedFragment extends Fragment {
public static Fragment newInstance(String position) {
TopRatedFragment f = new TopRatedFragment();
// Supply num input as an argument.
Bundle args = new Bundle();
args.putString("num", position);
f.setArguments(args);
return f;
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
Bundle b = getArguments();
if (b!=null){
String someText = b.containsKey("num")?b.getString("num"):null;
}
I'll explain the structure of my app :
Activity --> Fragment A (Inside that fragment (A) i have 3 Fragments (B, C, D) (viewpager)) --> Inside the first fragment(B) it contains a listview. Every item from that list launches a fragment E.
So i'm facing an issue here.
When i first launch my application Everything looks fine.
But when Fragment E get's visible to the screen the tabs gets all weird and be like :
Yeap! they got duplicated.
When i click on the listview, i commit the transition between the 2 fragments from a callback in the Activity :
transaction = getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.content_frame, PF);
transaction.addToBackStack(null);
transaction.commit();
When i want to go back to the previous fragment:
getFragmentManager().popBackStack();
Is the previous fragment getting recreated? And what can i do to solve it?
UPDATE --CODES:
Activity :
public class MainActivity extends FragmentActivity implements
IslamToolsFragment.OnToolsSelectedListener {
FragmentTransaction transaction;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (findViewById(R.id.content_frame) != null) {
if (savedInstanceState != null) {
return;
}
PagerActivity firstFragment = new PagerActivity();
getSupportFragmentManager().beginTransaction()
.add(R.id.content_frame, firstFragment).commit();
}
}
#Override
public void OnToolSelected(int position) {
// TODO Auto-generated method stub
switch (position) {
case 0:
PrayerFragment PF = new PrayerFragment();
transaction = getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.content_frame, PF);
transaction.addToBackStack(null);
transaction.commit();
break;
case 1:
QiblaFragment QF = new QiblaFragment();
transaction = getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.content_frame, QF);
transaction.addToBackStack(null);
transaction.commit();
break;
}
}
Fragment A (Which contains 3 fragments):
public class PagerActivity extends Fragment implements ActionBar.TabListener {

mAppSectionsPagerAdapter = new AppSectionsPagerAdapter(

mPager.setAdapter(mAppSectionsPagerAdapter);
int icons[] = { R.drawable.ic_action_storage,
R.drawable.ic_action_overflow, R.drawable.ic_action_person };
mPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {
#Override
public void onPageSelected(int position) {
actionBar.setSelectedNavigationItem(position);
}
});
for (int i = 0; i < mAppSectionsPagerAdapter.getCount(); i++) {

Thanks! is it something related to the savedinstancestate?
Your code design is a little bit wrong, fragments are actually pieces of activities, it does not make sense to me to create a fragment with more fragments inside in this situations, what you should do is create an activity for the viewpager and put into that activity your 3 fragments.
I have a similar app and this is how i handle the navigation between tabs:
pager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
#Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
}
#Override
public void onPageSelected(int position) {
actionBar.setSelectedNavigationItem(position);
}
#Override
public void onPageScrollStateChanged(int state) {
}
The above code changes the item selected of the action bar BUT does not change the view below the view pager tabs, you need to implement the following to do this:
#Override
public void onTabSelected(ActionBar.Tab tab, FragmentTransaction fragmentTransaction) {
pager.setCurrentItem(tab.getPosition());
}
#Override
public void onTabUnselected(ActionBar.Tab tab, FragmentTransaction fragmentTransaction) {
}
#Override
public void onTabReselected(ActionBar.Tab tab, FragmentTransaction fragmentTransaction) {
}
Currently I have made 3 tabs. On each tab (fragment) there is a thread to fetch content and display it with a listview through an ArrayAdapter.
Now when you scroll through the tabs the thread gets executed again and again (not necessary).
Is there a way to stop this ? Or do I need to write the content to external storage for faster access ?
Also sometimes I see the same data on different tabs , how to avoid this ?
Thanks in advance
This is some code that I use inside my fragment which that is called multiple times when swiping :
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView;
rootView = inflater.inflate(R.layout.leadlist, container, false);
profielen = new ArrayList<Profile>();
new getLeaderboards().execute(url);
lv = (ListView) rootView.findViewById(android.R.id.list);
lbadapter = new LeaderBoardAdapter(this.getActivity(), R.layout.item_layout, profielen);
return rootView;
}
public static class getLeaderboards extends AsyncTask<String, Void, JsonObject> {
#Override
protected JsonObject doInBackground(String... urls) {
JsonObject x = parseURL.GetJSON(urls[0]);
return x;
}
#Override
protected void onPostExecute(JsonObject obj) {
Gson gson = new Gson();
System.out.println(obj.toString());
JsonArray arr = obj.get("rows").getAsJsonArray();
for (int i=0;i<10;i++) {
Profile pat = gson.fromJson( arr.get(i) , Profile.class);
profielen.add(pat);
}
lv.setAdapter(lbadapter);
}
}
My FragmentActivity :
public class LeaderboardsActivity extends FragmentActivity implements
ActionBar.TabListener {
private ViewPager viewPager;
private TabsPagerAdapter mAdapter;
private ActionBar actionBar;
private String[] tabs = { "Tab1", "Tab2", "Tab3" };
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().requestFeature(Window.FEATURE_ACTION_BAR);
setContentView(R.layout.leaderboard);
Intent i = getIntent();
String region = i.getStringExtra("region");
viewPager = (ViewPager) findViewById(R.id.pager);
actionBar = getActionBar();
getActionBar().setDisplayShowTitleEnabled(false);
getActionBar().setDisplayShowHomeEnabled(false);
mAdapter = new TabsPagerAdapter(getSupportFragmentManager(),region);
viewPager.setAdapter(mAdapter);
actionBar.setHomeButtonEnabled(false);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
for (String tab_name : tabs) {
actionBar.addTab(actionBar.newTab().setText(tab_name)
.setTabListener(this));
}
viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
#Override
public void onPageSelected(int position) {
actionBar.setSelectedNavigationItem(position);
}
#Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
}
#Override
public void onPageScrollStateChanged(int arg0) {
}
});
}
#Override
public void onTabReselected(Tab tab, FragmentTransaction ft) {

#Override

viewPager.setCurrentItem(tab.getPosition());
}
#Override
