ViewPager

• Scrollable
• Set image on tab bar
• MainActivity

Refreshable ListView

• Add headers
• Add footers (in this case, showing a ProgressBar) to load more items when it reaches the end.

Note: Requesting split data from your server many times, and scroll to download next group of data to fill in ListView.
Request fewer items at a time so that users don't download the whole data, they just download what the see.
And it's friendly if you need to show data with different pages.
Using Universal-Image-Loader, Fresco, and others libraries to load images.

• Pull to refresh with SwipeRefreshLayout
• RefreshableListFragment

Refreshable GridView (Use RecyclerView instead of GridView)

• Using focusCrop scales images to focus point instead of the center so that you won't crop someone's face. Click to see more about FocusCrop.
