二、使用方法：

public class PicassoActivityFragment extends Fragment implements View.OnClickListener {

    @InjectView(R.id.btn_down)
    protected Button btnDown;
    @InjectView(R.id.iv_down)
    protected ImageView ivDown;

    public PicassoActivityFragment() {
    }

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

        btnDown.setOnClickListener(this);
        return view;
    }


    @Override
    public void onClick(View view) {
        if (view == btnDown){
            RequestCreator creator = Picasso.with(getActivity()).load("http://cdn.duitang.com/uploads/blog/201310/05/20131005152937_GGAmZ.thumb.600_0.jpeg");
            //fit让图片自动适应
            creator.rotate(50).fit().into(ivDown);
        }
    }
}
