Pulltorefreshlistview mainly uses:

1. Locate the drop-down refresh control by using the Findviewbyid () method

2. Set the adapter, then use the Setadapter () method to bind the adapter and data list

3. Using the onrefreshlistener<listview> () listener, rewrite the listener's Onrefresh () method,

4. Set the listener using the Setonrefreshlistener () method.

The 5.onRefresh () method implements asynchronous processing through handler.
