Figure 1 left: Main Program; middle: Pull down to refresh latest; Right: Pull up to load more

The code is tedious and will not be posted ~ For specific code, please download the Demo after this article.

Note:

• The custom control PullListView and its listening PullListViewListener. PullListView inherits the ListView and OnScrollListener, enabling the upper and lower pull ListView to refresh and load more;
• The custom Status Control StatusView inherits LinearLayout and adds the top and bottom of the PullListView. When the PullListView is pulled up and down, the corresponding status information is displayed;
• Status enumeration RefreshStatus indicates the type of status information.
