修改

我目前发现它只能在Fregment中使用，但在Activity中正常工作。

问题已修复。

我可以改变

android:configChanges="orientation|screenSize"

每个<Activity

都有

android:configChanges="orientation|keyboardHidden|screenSize"

Answer 1

将此添加到您的清单

<activity android:name=".MainActivity"  
    android:configChanges="keyboardHidden|orientation|screenSize" >

当我将屏幕景观移动到potrate时，我的应用程序崩溃了
