1.使用方式

Intent intent = new Intent(FriendCircleActivity.this, ImageGralleryPagerActivity.class);
//0，索引，第几张图片

intent.putExtra(ImageGralleryPagerActivity.EXTRA_IMAGE_INDEX, 0);

 ArrayList<String> imgs = new ArrayList<String>();

 imgs.add(“图片URL”);

intent.putStringArrayListExtra("imgs", imgs);

startActivity(intent);

2.展示大图Activity
