How can I get the application context in that situation?

I'm newbie at Android Development, I have been learning this about 4 months.

I'm trying to get my application context to use an library called picasso. I built a costume adapter to load images to my imageview.

But I'm having some issues getting the application context, I tried to use getBaseContext, getActivity(), and I created a variable to get the context, but it didn't work.

I'm building my app using fragments, my code:

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_one, container, false);

        final ArrayList alEvents = new ArrayList<String>();

        eventsAdapter = new costumeadapter(getActivity(), alEvents,
                R.layout.list, new String[] { ITEM_NAME, ITEM_EVENT },
                new int[] { R.id.name, R.id.current_event });

        lvEvents.setAdapter(eventsAdapter);

...

}

My costume adapter:

public class costumeadapter extends SimpleAdapter {

    Context context;

    public costumeadapter(FragmentActivity fragmentActivity,
            List<? extends Map<String, ?>> data, int resource, String[] from,
            int[] to) {
        super(fragmentActivity, data, resource, from, to);
        // TODO Auto-generated constructor stub
    }

    public View getView(final int position, final View convertView,
            final ViewGroup parent) {
        View v = super.getView(position, convertView, parent);
        ImageView bg_image = (ImageView) v.findViewById(R.id.bg_image);


        Picasso.with(context)
                .load("http://pplware.sapo.pt/wp-content/uploads/2015/06/Wallpaper_10.jpg")
                .into(bg_image);

        return v;

    }

}

Can you guys give me any solution? Thanks.

You can transmit Activity to fragment. At the fragment class, override onActivityCreated to get Activity which is contained fragment. Then getting context from this activity

You should have include how you have tried to get the context that is not working for you but I think this will work

public View getView(final int position, final View convertView,
        final ViewGroup parent) {
    View v = super.getView(position, convertView, parent);
    ImageView bg_image = (ImageView) v.findViewById(R.id.bg_image);


    context = parent.getContext();
    Picasso.with(context)
            .load("http://pplware.sapo.pt/wp-content/uploads/2015/06/Wallpaper_10.jpg")
            .into(bg_image);

    return v;

}

Use convertView.getContext() or v.getContext() to get Context for passing to Picasso.with method as:

Picasso.with(convertView.getContext())
       .load("<IMAGE_URL>")
       .into(bg_image);

In your adapter, declare:

final Context localContext;

and after:

 public costumeadapter(FragmentActivity fragmentActivity,
            List<? extends Map<String, ?>> data, int resource, String[] from,
            int[] to) {
        super(fragmentActivity, data, resource, from, to);
        this.localContext = fragmentActivity;
    }

in localContext variable you will have a context.
