我有一个微调的问题下拉列表，然后改变方向。

I have a problem with a spinner drop down list and changing orientations.

在我的活动，我显示一个对话框，在其中我有两个微调。当显示给用户的对话框，用户更改屏幕方向，一切都OK--在我的onPause，我只是简单地关闭对话框。

In my activity, I display a dialog in which I have two spinners. When the dialog is shown to the user and the user changes the screen orientation, everything is OK-- in my onPause, I just simply dismiss the dialog.

如果用户点击微调，一个下拉列表显示用户改变方向之前。但是，我遇到了一个错误，当用户不选择从下拉列表中任何东西，只留下改变方向之前展开的列表中。

If the user taps on the spinner, a drop-down list is shown to user before changing orientation. But I have encountered an error when the user doesn't select anything from the drop-down list, and just leaves the list expanded before changing orientation.

我已经尝试了很多事情来解决这个问题（即 spinner.setSelection（0）在的onSaveInstanceState（） ， 等等。）。我的想法是从code关闭下拉列表中，当用户不选择项目和方向发生变化。

I have tried many things to solve this problem (i.e. spinner.setSelection(0) in onSaveInstanceState(), etc.). My idea is to close the drop-down list from the code when the user doesn't select item and an orientation change occurs.

修改

解决方法：

最后，我找到了原因这*放大器;＃$％的误差。在表现在我的活动我有 机器人：configChanges =方向，当我将其更改为安卓！configChanges =keyboardHidden |定位的问题消失了。

Finally I found what cause this *&#$% error. In manifest in my Activity I have android:configChanges="orientation" , when I change it to android:configChanges="keyboardHidden|orientation" problem is gone !

THX 4帮助！

推荐答案

我有一个idea以prevent方向更改显示时微调对话框，却发现没有可靠的方法要做到这一点。我发现最好的解决办法是，replace微调器有一个按钮。

I had an idea to prevent orientation changes when dialog with spinner is displayed, but found that there is no reliable way to do that. The best solution that I found is to replace spinner with a button.
