Questions:

In the new gmail application (4.5) the refresh is done by “Pull-to-Refresh” action in the Actionbar:

Where can I find more information about that “Pull-to-Refresh”?

How to&Answers:

Chris Banes (the same guy that implemented the best pull to refresh component for android) also implemented the GMail like Pull To Refresh.

You can find it here: https://github.com/chrisbanes/ActionBar-PullToRefresh

Note that this project is still under development so the current API may change.

Update:

Both ActionBar-PullToRefresh and Android-PullToRefresh are deprecated. Standart way to implement a pull to refresh is using SwipeRefreshLayout of v4 support library.

Here is the required steps:

  • Create a root or sub layout with SwipeRefreshLayout and put a scrollable item in it.

    <android.support.v4.widget.SwipeRefreshLayout
        ...>
    
    <ListView
        .... />
    
    </android.support.v4.widget.SwipeRefreshLayout>
    
  • Add a refresh listener

    SwipeRefreshLayout srl = ...;
    srl.setOnRefreshListener(
        new SwipeRefreshLayout.OnRefreshListener() {
            @Override
            public void onRefresh() {
                ...
            }
        });
