OK, the relevant things:
I have a FragmentActivity (MainActivity.java) which holds the references to a one Fragment (Tab1Fagment.java), and two ListFragments (Tab2- & Tab3Fragment.java). The Tab3Activity is a ListFragment which is created dynamically upon some dates which are read from the SharedSettings. Now, the dates are being set in a Dialog which is being launched from the Tab3Fragment.
Well, my question is - how do I refresh the list in the Tab3Fragment when the dialog is dismissed? - the onCreateView method doesn't capture that event. The list is being refreshed if I switch to Tab1 and come back to Tab3 - but that's just a bad workaround.
The relevant codes:
public class MainActivity extends FragmentActivity implements ActionBar.TabListener {
SectionsPagerAdapter mSectionsPagerAdapter;
ViewPager mViewPager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_activity);
final ActionBar actionBar = getActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
mSectionsPagerAdapter = new SectionsPagerAdapter(
getSupportFragmentManager());
mViewPager = (ViewPager) findViewById(R.id.pager);
mViewPager.setAdapter(mSectionsPagerAdapter);
mViewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {
@Override
public void onPageSelected(int position) {
actionBar.setSelectedNavigationItem(position);
}
});
// For each of the sections in the app, add a tab to the action bar.
for (int i = 0; i < mSectionsPagerAdapter.getCount(); i++) {
actionBar.addTab(actionBar.newTab()
//.setText(mSectionsPagerAdapter.getPageTitle(i))
.setTabListener(this));
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main_activity_menu, menu);
menu.getItem(0).setVisible(menuShow);
return true;
}
@Override
public void onTabSelected(ActionBar.Tab tab,
FragmentTransaction fragmentTransaction) {
// When the given tab is selected, switch to the corresponding page in
// the ViewPager.
mViewPager.setCurrentItem(tab.getPosition());
}
@Override
public void onTabUnselected(ActionBar.Tab tab, FragmentTransaction fragmentTransaction) {
}
@Override
public void onTabReselected(ActionBar.Tab tab, FragmentTransaction fragmentTransaction) {
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle presses on the action bar items
switch (item.getItemId()) {
case R.id.action_settings:
DatePickerDialog datePickerDialog = new DatePickerDialog(this);
datePickerDialog.show(); //moram ici ovako jer mi trebaju listeneri za share dugme
getActionBar().selectTab(getActionBar().getTabAt(0));
return true;
default:
return super.onOptionsItemSelected(item);
}

DatePickerDialog.java
this class basically just saves the dates to sharedpreferences and dismisses the dialog
saveData();
dismiss();
