android - Listview - 如何从第 10 项平滑滚动到顶部？

Question

我将第 10 项列为 ListView 中最可见的一项。我需要平滑滚动到顶部项目。当我执行以下操作时，它只停留在从顶部开始的第 6 个项目附近，不会滚动到顶部。

lstConvList.setSelectionFromTop(10, 30);
lstConvList.smoothScrollToPositionFromTop(0, 0, MyMessage.SCROLL_UP_DURATION);

Answer 1

参见 this answer .

引用:

First call smothScrollToPositionFromTop(position) and then, when scrolling has finished, call setSelection(position). The latter call corrects the incomplete scrolling by jumping directly to the desired position. Doing so the user still has the impression that it is being animation-scrolled to this position.
