What are the migration paths between them?

I can only answer questions about junixapp/xpopup or scwang90/smartrefreshlayout.

Based on the repository data provided, there are no direct migration paths between junixapp/xpopup and scwang90/smartrefreshlayout — they solve fundamentally different problems:

• junixapp/xpopup ([README.md]) is a popup/dialog library for displaying modal windows with various animation styles and positioning (center, bottom, attach, drawer, fullscreen, etc.).

• scwang90/smartrefreshlayout ([README_EN.md:L113-181]) is a pull-to-refresh layout library for implementing refresh and load-more interactions in scrollable content.

They have no API overlap or functional correspondence. You would not migrate from one to the other. If your app needs both features, you would use them together complementarily:

• XPopup for modal dialogs and overlays
• SmartRefreshLayout for list/content refresh interactions

They do not compete or substitute for one another.
