@Override
        public void onClick(View v) {
            ArrayList<BaseMedia> iMedias = new ArrayList<>();
            BaseMedia media = (BaseMedia) v.getTag();
            iMedias.add(media);
            onFinish(iMedias);
        }
the most easy to implement {@link PickerContract.View} to show medias with google's Bottom Sheet </br>
for simplest purpose, it only support SINGLE_IMG and VIDEO Mode.
for MULTI_IMG mode, use {@link BoxingViewFragment} instead.
