Picasso 加载图片到RelativeLayout之解决方案

  Picasso.with(getActivity()).load(R.drawable.mine_top_bg).into(new Target() {

                            @Override
                            public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
                                if (android.os.Build.VERSION.SDK_INT > 15) {
                                    rl_mine_top.setBackground(new BitmapDrawable(getActivity().getResources(), bitmap));
                                } else {
                                    rl_mine_top.setBackgroundDrawable(new BitmapDrawable(getActivity().getResources(), bitmap));
                                }
                            }

                            @Override
                            public void onBitmapFailed(final Drawable errorDrawable) {
                            }

                            @Override
                            public void onPrepareLoad(final Drawable placeHolderDrawable) {
                            }
                        });
