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 ex

Answer 1

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.

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);

From a fragment use :

 getActivity().getString(...)

From an adapter use :

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

Yes, you need a context to access the resources.
