Access to getString() in android.support.v4.app.FragmentPagerAdapter?

Question

In a class extending android.support.v4.app.FragmentPagerAdapter, is there any way to get access to the Context.getString(..) method without the extending class being an inner class of an activity or passing in some context from the outside?

Thanks for any hint!

From a fragment use :

 getActivity().getString(...)

From an adapter use :

 getContext().getResources().getString(...)

Yes, you need a context to access the resources.

Note that `getActivity()` will be null until `onActivityCreated()` is invoked. – dmon Jan 01 '13 at 17:42
thanks, but unfortunately I am in a FragmentPagerAdapter, not a Fragment! – stefan.at.kotlin Jan 01 '13 at 17:43
use getContext() so, and if you don't have access to a context, pass it. – Snicolas Jan 01 '13 at 17:45
Yes, just pass the context where you need it. – Snicolas Nov 07 '13 at 17:49

From an Activity, use:

this.getString(R.string.string_name);

From a Fragment, use:

getActivity.getString(R.string.string_name);

From an adapter, use:

getContext().getResources().getString(R.string.string_name);

I had a similar issue. From a drawer layout, I wanted to decide which fragment to use in a method called from a helper class.

So in onCreateView...

String form = getResources().getStringArray(R.array.drawer_array)[i];
        Context context = getActivity().getApplicationContext();

        FragmentHelper fh = new FragmentHelper();
        int myFragment = fh.getCurrentFragment(form,context);

And in public FragmentHelper()...

    public int getCurrentFragment(String form, Context context){
              ...
              context.getResources().getString(R.string.label_item1);
              ...
    }

The trick being to add context in front of getResources(). Otherwise, my stack showed that the fragment was not attached to an activity.

Hope this helps someone.
