Answer 1

you can use something like that

        Picasso.with(mContext).load(currentEventData.mImageSrc).into(new Target() {
            @Override
            public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
                 mParentLayout.setBackground(new BitmapDrawable(getResources(),bitmap);
            }

            @Override
            public void onBitmapFailed(Drawable errorDrawable) {

            }

            @Override
            public void onPrepareLoad(Drawable placeHolderDrawable) {

            }
        });
