android 旋转手机的时候,如何忽略onCreate再次被系统调用？

实现一个程序，主要是不想在手机横竖屏的时候重新onCreate,所以在配置文件中增加了配置选项：

1. android:configChanges="orientation|keyboardHidden"

可是跟踪发现，在屏幕旋转的时候还会继续调用onCreate,大家有遇到这样的问题吗？

从sdk 3.2+，当手机屏幕发现旋转，新增加一个screenSize，这个值也会跟着发生改变。所以要不想重绘界面，需要把screenSize这项也要加入到配置文件中。

1. android:configChanges="orientation|keyboardHidden|screenSize"

Android Developer描述如下：
Caution: Beginning with Android 3.2 (API level 13), the "screen size" also changes when the device switches between portrait and landscape orientation. Thus, if you want to prevent runtime restarts due to orientation change when developing for API level 13 or higher (as declared by the minSdkVersion and targetSdkVersion attributes), you must include the "screenSize" value in addition to the "orientation" value.
