我怎样才能保持整个屏幕重新定位一个GridView控件（它充满了搜索结果）的滚动位置？

How can I maintain the scroll position of a GridView (it's filled with search results) throughout a screen reorientation?

我在GridView一个片段里，当我旋转屏幕就跳回到列表的顶部。

I have the GridView inside a Fragment, and when I rotate the screen it jumps back up to the top of the list.

要使它变得更加棘手，在横向模式下我的GridView有3列。在纵向模式下，它有2列。

To make it even more tricky, in landscape mode my GridView has 3 columns.. in portrait mode it has 2 columns.

我似乎无法找出如何保持片段的GridView控件滚动到附近的任何地方，它应该是屏幕的方向改变时。

I can't seem to figure out how to keep the fragment's GridView scrolled to anywhere near where it should be when the screen orientation changes.

推荐答案

您可以试试这个：

首先，你必须通过调用来获取GridView控件的当前滚动位置：

Initially you have to get the current scrolling position of the GridView by calling:

int index = gridview.getFirstVisiblePosition();

然后你要保存这个值，而取向的变化和GridView控件再次创建时，你有你的GridView控件移动到该索引。

Then you have to save this value while orientation changes and when the GridView is created again you have to move your gridview to this index.

我想这可能是工作：

gridview.smoothScrollToPosition(int index)

希望这有助于！
