tabs in viewpager not responding in a sequence android

In my android app I am using a tab swipe view having 4 tabs first tab displays data on the UI and is calling a WS via AsyncTask, data returned by the WS is populating a pojo and this pojo is passed to other tab(fragments)
The problem I face is Tabs are not executed in a sequence when I click on first tab, first and 2 tab are executing before calling WS due to this strange behaviour I cant get data in my second tab

One solution:
In your activity, run WS with Asynctask, and then call the fragments that need data to update view
class yourActivity {
#Override
public void onCreate(Bundle savedInstanceState) {
... ...
//set up your tabs with fragments
... ...
//WS: Your asynctask requesting data from server
(new AsyncTask<... ...>() {
... ...
#Override
protected void onPostExecute(dataSet) {
//here you have got your data set from server then inform tabs to update
YourFragment frag = (YourFragment)getSupportFragmentManager().findFragmentById(R.id.your_fragment);
frag.updateView(dataSet);
}
}).execute();
}
}
In each tab/fragment that needs shared data set, define a method to update view with the data set
class YourFragment extebds Fragment{
... ...
public void updateView(dataSet)
{
//update this fragment view with dataSet
//and stop your waiting dialog
}
}
Hope this solution works for you.

Android - Swiping without Tabs

NoteActivity Code:
public class NoteActivity extends FragmentActivity implements ActionBar.TabListener
{
private ViewPager viewPager;
private TabsPagerAdapter mAdapter;
private ActionBar actionBar;
// Tab titles
private String[] tabs = {"Note", "Note Info"};
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_note);
viewPager = (ViewPager) findViewById(R.id.pager);
actionBar = getActionBar();
mAdapter = new TabsPagerAdapter(getSupportFragmentManager());
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));
}
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 onTabSelected(Tab tab, FragmentTransaction ft) {
// TODO Auto-generated method stub
viewPager.setCurrentItem(tab.getPosition());
}
#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
}
}
TabsPageAdapter.Java
public class TabsPagerAdapter extends FragmentPagerAdapter
{
public TabsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int index) {
switch (index)
{
case 0:
return new NoteFragment();
case 1:
return new NoteInfoFragment();
}
return null;
}
#Override
public int getCount()
{
// get item count - equal to number of tabs
return 2;
}
}
So basically, I used an example of Tabs View and got the Tabs working and it looks like this:
What would I have to do to make it just swipeable without the Tabs showing. An example is like Snapchat. It definitely uses the Swipe view control but the tabs are hidden. Can someone please show me how to get this done?

Since you already have a ViewPager in your code, all you have to do is remove the code that creates the ActionBar tabs (under the comment // Adding tabs), as well as the code that synchronizes the tab selection with the current page (start with the ViewPager.OnPageChangeListener and the ActionBar.TabListener callbacks and see if anything breaks).

i had add add 3 tab Now the problem is that when i set some data in tab1 view and move to tab2 the reselect tab1 the data on tab1 is as it is but when i move to tab3 to tab1 then tab1 data is clear. so cany anyof you have idea to solve this?

At the moment your code appears to be partly action bar tabs and partly ordinary fragments.
If you are trying to use action bar tabs then you need a tab listener. In onTabSelected you should add/replace and in onTabUnselected you should remove.
Please see http://developer.android.com/guide/topics/ui/actionbar.html
section "adding navigation tabs" for a good example.

Tab and fragments no support intents

Hi I have a problem with tab+fragment, here frist I have the class which will create the tab:
public class TestSwipeABActivity extends FragmentActivity {
FragmentTransaction transaction;
static ViewPager mViewPager;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Fragment tabOneFragment = new TabOne();
Fragment tabTwoFragment = new TabTwo();
PagerAdapter mPagerAdapter = new PagerAdapter(getSupportFragmentManager());
mPagerAdapter.addFragment(tabOneFragment);
mPagerAdapter.addFragment(tabTwoFragment);
//transaction = getSupportFragmentManager().beginTransaction();
mViewPager = (ViewPager) findViewById(R.id.pager);
mViewPager.setAdapter(mPagerAdapter);
mViewPager.setOffscreenPageLimit(2);
mViewPager.setCurrentItem(0);
mViewPager.setOnPageChangeListener(
new ViewPager.SimpleOnPageChangeListener() {
#Override
public void onPageSelected(int position) {
// When swiping between pages, select the
// corresponding tab.
getActionBar().setSelectedNavigationItem(position);
}
});
ActionBar ab = getActionBar();
ab.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
Tab tab1 = ab.newTab().setText("Tab One").setTabListener(new TabListener<TabOne>(
this, "tabone", TabOne.class));
Tab tab2 = ab.newTab().setText("Tab Two").setTabListener(new TabListener<TabTwo>(
this, "tabtwo", TabTwo.class));
ab.addTab(tab1);
ab.addTab(tab2);
}
public static class TabListener<T extends Fragment> implements ActionBar.TabListener {
private Fragment mFragment;
private final Activity mActivity;
private final String mTag;
private final Class<T> mClass;
/** Constructor used each time a new tab is created.
* #param activity The host Activity, used to instantiate the fragment
* #param tag The identifier tag for the fragment
* #param clz The fragment's Class, used to instantiate the fragment
*/
public TabListener(Activity activity, String tag, Class<T> clz) {
mActivity = activity;
mTag = tag;
mClass = clz;
}
/* The following are each of the ActionBar.TabListener callbacks */
public void onTabSelected(Tab tab, FragmentTransaction ft) {
// Check if the fragment is already initialized
if (mFragment == null) {
// If not, instantiate and add it to the activity
mFragment = Fragment.instantiate(mActivity, mClass.getName());
ft.add(android.R.id.content, mFragment, mTag);
} else {
// If it exists, simply attach it in order to show it
ft.attach(mFragment);
}
}
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
if (mFragment != null) {
// Detach the fragment, because another one is being attached
ft.detach(mFragment);
}
}
public void onTabReselected(Tab tab, FragmentTransaction ft) {
// User selected the already selected tab. Usually do nothing.
}
public void onTabReselected(Tab arg0,
android.app.FragmentTransaction arg1)
{
// TODO Auto-generated method stub
}
public void onTabSelected(Tab arg0, android.app.FragmentTransaction arg1)
{
// TODO Auto-generated method stub
mViewPager.setCurrentItem(arg0.getPosition());
}
public void onTabUnselected(Tab arg0,
android.app.FragmentTransaction arg1)
{
// TODO Auto-generated method stub
}
}
public class PagerAdapter extends FragmentPagerAdapter {
private final ArrayList<Fragment> mFragments = new ArrayList<Fragment>();
public PagerAdapter(FragmentManager manager) {
super(manager);
}
public void addFragment(Fragment fragment) {
mFragments.add(fragment);
notifyDataSetChanged();
}
#Override
public int getCount() {
return mFragments.size();
}
#Override
public Fragment getItem(int position) {
return mFragments.get(position);
}
}
}
And then here is the fragment for each tab, for example the two one:
public class TabTwo extends Fragment
{
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
View view = inflater.inflate(R.layout.tabtwo, container, false);
Button Activity1= (Button) view.findViewById(R.id.button1);
Activity1.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent intent = new Intent().setClass(this,ABActivity.class);
startActivity(intent);
}
});
return view;
}
}
The error was: The method setClass(Context, Class<?>) in the type Intent is not applicable for the arguments (new View.OnClickListener(){},
Class<ABActivity>)
I try out changing the context to TabTwo.this, tabtwo.getcontext.this, but nothing, eclipse says to change .setclassName but doesnt work.
If you could help... THANKS!!!

Try this
Intent intent = new Intent(getActivity(),ABActivity.class);
startActivity(intent );

HI I just have a solution:
public void onClick(View view) {
Activity activity = getActivity();
Intent intent = new Intent().setClass(activity, ABActivity.class);
startActivity(intent);
}
Explanation: "Another difference is that a Fragment is not a subclass of Context. This means that a Fragment can not be launched as a component inside your app and therefore always has to live inside of an Activity. This also means that whenever you need a Context inside of a Fragment, you need to get access to the parent Activity. You can do this by using the getActivity() method as we have done in the Fragment button's OnClickListener callback. You need to watch out because getActivity() can return null depending on where the Fragment is in the Activity's lifecycle. So, you should also include a check to see if the Activity is null before you use it."

listviewselection in a listfragment in a tab

I have the following problem. I have an app with a viewpager and two tabs. The two tabs are two listfragments. Now I want that if the user selects an item in the first tab, that the 5th item is selected in the second tab. (the second tab is the translation of text from the first item). My problem is that when i select an item in the first tab, and now switch to the second tab, there is nothing selected.
When I click something in the first tab I call a function in the Parent activity which calls a function in the second fragment which should select the 5th Item.
This is the code of the Fragment activity:
public class Dailyquran extends FragmentActivity implements ActionBar.TabListener {
SectionsPagerAdapter mSectionsPagerAdapter;
ViewPager mViewPager;
public ArrayList<Tweet> tweets = new ArrayList<Tweet>();
public ArrayList<Tweet> tweets2 = new ArrayList<Tweet>();
//private static ArrayList<String> roomList;
public String a;
public static int laenge_inhalt;
public static int selected;
public static String sure_media;
public static String vers_media;

//int tabwahl=0;

inflater.inflate(R.menu.activity_dailyquran, menu);
playMenu = menu.findItem(R.id.menu_play);
return true;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setTitle("Daily Quran");
setContentView(R.layout.activity_dailyquran);
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
// Set up the action bar.
final ActionBar actionBar = getActionBar();
// set the app icon as an action to go home
actionBar.setDisplayHomeAsUpEnabled(true);
//enable tabs in actionbar
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
// Set up the ViewPager with the sections adapter.
mViewPager = (ViewPager) findViewById(R.id.pager);
mViewPager.setAdapter(mSectionsPagerAdapter);
// When swiping between different sections, select the corresponding tab.
// We can also use ActionBar.Tab#select() to do this if we have a reference to the
// Tab.
mViewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {
#Override
public void onPageSelected(int position) {
actionBar.setSelectedNavigationItem(position);
}
});
for (int i = 0; i < mSectionsPagerAdapter.getCount(); i++) {
// Create a tab with text corresponding to the page title defined by the adapter.
// Also specify this Activity object, which implements the TabListener interface, as the
// listener for when this tab is selected.
actionBar.addTab(
actionBar.newTab()
.setText(mSectionsPagerAdapter.getPageTitle(i))
.setTabListener(this));
}
main();
}

AND THIS IS THE RELEVANT CODE OF THE SECOND FRAGMENT, I can see the string "Hallo" is in the console, so the function is really called, but i the Item isnt selected.
public void change_selected()
{
System.out.println("Hallo");
ListView list=getListView();
list.setSelection(4);
}

Its working now when i add this code in the function on_changed in the parent activity:
TransliterationFragment fragment_meaning = (TransliterationFragment) getSupportFragmentManager().findFragmentByTag("android:switcher:"+R.id.pager+":1");
fragment_meaning.change_selected(); // do what updates are required
