You need to change below line:
From
spinner=(Spinner)container.findViewById(R.id.spinner1);
To
spinner=(Spinner)rootView.findViewById(R.id.spinner1);
Reason: You need to bind your UI widgets with your fragment view not with Viewgroup.

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

Errors in Navigation Drawer Activity

I'm trying to create a navigation drawer for Android. I've followed these pages (this and this) but now I'm stuck.
Here's my code, based on the planet navigation drawer:

}
}
}
I get different errors depending on the changes I make.
Like it is right now, I get
java.lang.NullPointerException: Attempt to invoke virtual method 'void android.app.ActionBar.setTitle(java.lang.CharSequence)' on a null object reference
ActionBarActivity is deprecated so I'm not going to use it but if I change Activity to AppCompatActivity, I get
java.lang.IllegalArgumentException: AppCompat does not support the current theme features
What am I doing wrong? Which is better to use: Activity, ActionBarActivity or AppCompatActivity? Thanks in advance

Thanks to Raghunandan I managed to fix this: I changed the Activity to AppCompatActivity and replaced getActionBar for getSupportActionBar. I don't have any more NPE

Problem: my compiler was not showing that these android:attr/* are not supported in API level 10. I found a solution.
To support lower versions, instead of removing the following three parameters,
android:textAppearance="?android:attr/textAppearanceListItemSmall"
android:background="?android:attr/activatedBackgroundIndicator"
android:minHeight="?android:attr/listPreferredItemHeightSmall"
You can actually replace them with equivalent values/resources.
The equivalent values can be obtained from https://github.com/android/platform_frameworks_base/blob/master/core/res/res/values/themes.xml
Now,
a) android:textAppearance="#android:style/TextAppearance.Medium"
b) Download a selector from https://github.com/habzy/Test0011_DialerPad/blob/master/res/drawable/list_item_activated_background.xml
In the above project browse the resources in hdpi,mdpi etc and get files named list_activated_holo.9.png
Finally
android:background="#drawable/activated_background_holo_dark"
c) From the equivalent values obtained , we know that listPreferredItemHeightSmall is 48dip
android:minHeight="48dip"
