Refresh or Update the listadapter from a fragment in android eclipse

I have a MainActivity with some fragments to run when click on side navigation menu. In the side navigation menu there is a item Called Number of SMS that shall be updated as soon as in the other fragment you choose the desired phone number. but the problem is I do not know how to refresh the list adapter from that fragment. I defined a class called allvalues which contains all my global variables. The variable responsible for SMS count is allvalues.NumberOfLocations
here is the code of MainActivity:

and this is the other Fragment which in this fragment, the phone numbers already user, saved are going to be showed in a list which on click of the number, first the number will be selected and then the allvalues.NumberOfLocations should be updated which equals to the number of received messages for the selected number.

but the number in the inside the navigation drawer does not update...
I also tried to call the navigation adapter after the line:
allvalues.NumberOfLocations = i + "";
but it did not work...
please help me...

I'd suggest to create a custom listener in your fragment like this :
public interface FragmentListener {
void refreshData();
}
and declare a variable for this listener in your fragment :
private FragmentListener listener;
and in your onItemClickListener:
listener.refreshData();
now create a method in your fragment to set this listener:
public void setListener(FragmentListener listener) {
this.listener = listener;
}
finally in your activity when you create your fragment :
ChoosePhoneNumber fragment = new Fragment();
fragment.setListener(new FragmentListener() {
public void refreshData() {
//Whatever you want to do.
}
});

I achieved the goal by simply refresh the MainActivity (reload it) again from the ChoosePhoneNumber fragment by adding these two lines at the end of the Fragment:
getActivity().finish();
getActivity().startActivity(getActivity().getIntent());

startActivity in setOnClickListener onClick on fragment

My problem is that does not start my new activity in fragment

Add a ProgressDialog into a NavigationDrawer

My code does a different kinds of things, but nothing exactly like what I want.
Problem -
When the app starts, the home doesn´t show.
When an item is selected, the lateral bar (NavigationDrawer) is not hidden. It is not showing the next fragment until I click outside the lateral bar.
Please help :(

If you have an idea on what is wrong, please help me fix the behavior.

For starters, try this, it should hide the lateral bar when you click on an item:
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
R.drawable.menu01, //nav menu toggle icon
R.string.app_name, // nav drawer open - description for accessibility
R.string.app_name // nav drawer close - description for accessibility
) {
public void onDrawerClosed(View view) {
super.onDrawerClosed(view);
getActionBar().setTitle(mTitle);
// calling onPrepareOptionsMenu() to show action bar icons
invalidateOptionsMenu();
}
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
//getActionBar().setTitle(mDrawerTitle);
// calling onPrepareOptionsMenu() to hide action bar icons
invalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
I'll look more deeply into your problem now.

Sliding Menu, Navigation Drawer with ListFragment

I use a Sliding Menu and Navigation Drawer with Fragments but I need a ListFragment instead of Fragment. When the app starts and I click on the link to open the side with the ListFragment the programm stopped, but I don't know whats the problem.. :/
This is my MainActivity with the Sliding Menu:
package at.example.sliding_menu;

Retrieving the search query from child Fragment in Android?

And this is one of the Child:
import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class Fragment_Locations extends Fragment {

#Override

Bundle savedInstanceState) {

}
The Search in the Menu:
<item
android:id="#+id/action_search"
android:actionViewClass="android.widget.SearchView"
android:icon="#drawable/ic_action_search"
android:showAsAction="always"/>
Now I want to access the search (from the Action-bar which comes from the menu) query (the value that has been written in the search box) from multiple child of this Project and each will perform its own individual action. Now how to get the search query in the child Fragments?

In your Activity:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.action_bar, menu);
searchAction = menu.findItem(R.id.menu_search);
SearchView searchView = (SearchView) searchAction.getActionView();
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
// do your stuff with query
return true;
}
#Override
public boolean onQueryTextChange(String newText) {
// do something if needed
return false;
}
});
return super.onCreateOptionsMenu(menu);
}
You can send a query to your fragments via simple method call from activity.
