Pull to refresh like gmail new (4.5) application

Question

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"?

Answer 1

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() {
              ...
          }
      });
