I think you need to set load image from Picasso to ImageView inside Tab1Fragment.

And need to make sure Picasso load to ImageView after fragment already run onCreateView to inflate view and ImageView

I made an example

In activity

  PlaceholderFragment placeholderFragment = (PlaceholderFragment) mSectionsPagerAdapter.getItem(0);
  placeholderFragment.setIcon("http://openweathermap.org/img/w/01d.png");

Fragment

public class PlaceholderFragment extends Fragment {
    /**
     * The fragment argument representing the section number for this
     * fragment.
     */
    private static final String ARG_SECTION_NUMBER = "section_number";

    private ImageView imageView;

    public PlaceholderFragment() {
    }

    /**
     * Returns a new instance of this fragment for the given section
     * number.
     */
    public static PlaceholderFragment newInstance(int sectionNumber) {
        PlaceholderFragment fragment = new PlaceholderFragment();
        Bundle args = new Bundle();
        args.putInt(ARG_SECTION_NUMBER, sectionNumber);
        fragment.setArguments(args);
        return fragment;
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_main, container, false);
        TextView textView = (TextView) rootView.findViewById(R.id.section_label);
        textView.setText(getString(R.string.section_format, getArguments().getInt(ARG_SECTION_NUMBER)));
        this.imageView = rootView.findViewById(R.id.imageView);
        return rootView;
    }

    public void setIcon(String url) {
        if (imageView == null) {
            throw new RuntimeException("ImageView null, please make sure this setIcon function run after onCreateView");
        }
        Picasso.get().load(url).into(imageView);
    }
}
