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);
}
});
