你sdk版本是多少？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。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.
