Use of the official pull-down refresh control SwipeRefreshLayout

After reading this blog today, I found that the pull-down and refresh controls work very well. So I want to study how to use them and write a demo. In fact, it is very easy to use, but it is to be able to use this new build I have been updated for a long time, and then I went directly to the official website to download the latest ADT for solution.

The complete name of the control isAndroid. support. v4.widget. SwipeRefreshLayout

Therefore, the complete name must be used in the XML file. In addition, this name is similar to linearlayout and is used as the root node of the entire xml file.

In the java code, you only need to obtain the control and set an onRefreshListener for the control.

PlaceholderFragment Fragment SwipeRefreshLayout srl = "onRefresh" 3000srl. setRefreshing ();}
