解决方法GridView.scrollTo（）？ [英] workarounds for GridView.scrollTo()?

问题描述

正如这里，Android的GridView.scrollTo（）不工作。该解决方案中提到的方法， setSelectedPosition ，似乎并没有在的 GridView的

As mentioned here, Android's GridView.scrollTo() doesn't work. The method the solution mentioned, setSelectedPosition, doesn't seem to exist in GridView

smoothScrollToPosition 没有工作，但我真的不想动画。

smoothScrollToPosition does work, but I really don't want the animation.

有关背景下，我有一个的CursorAdapter -backed 的GridView ，我想以重置，即滚动到顶部，当我改变光标。

For context, I have a CursorAdapter-backed GridView, and I want the view to "reset", i.e. scroll to the top, when I change the cursor.

推荐答案

我一直在使用 setSelection（INT位置）对于这一点，它似乎工作得精细。要滚动到顶部，只需要用0的位置。

I've been using setSelection(int position) for this, and it seems to be working just fine. To scroll to the top, just use 0 for position.

从文档：

如果在触摸模式中，项目不会被选择，但它仍然会被适当地定位。

If in touch mode, the item will not be selected but it will still be positioned appropriately.

编辑： 后加code setSelection 作为一个Runnable：

Added code to post setSelection as a Runnable:

albumsView.post(new Runnable() {
    @Override
    public void run() {
        albumsView.setSelection(0);
    }
});
