Android ScrollView检测滚动动画的结束/完成

Question

My problem is simple: I would like to detect when ScrollView ended a scroll animation.

• We do not have access to the Scroller object of the ScrollView.
• ScrollView.onScrollChanged is not called when it's parameters t and oldt are the same (at the end of the scroll)

The only working solution I can find is the one below, it is checking every 100 ms to see if the scroll ended, that sounds horrible to me. https://stackoverflow.com/a/10198865/1310343

Is there a more elegant solution?

Answer 1

Try extending the ScrollView class and override the onScrollChanged method. That should work. With the 'getMaxScrollAmount' method you should be able to find if the scrolling is done.
