网上大部分人都说是因为同一个页面（Activity），不同的View使用了相同的ID，导致在恢复时，findViewById，强制转换SaveState类型错误，可是我对比了半天整个工程中就一个SlidingTabLayout（继承HorizontalScrollView）使用了android:id="@+id/slidingTabLayout"，应该不是网友说的这种情况，但是我也不知道为什么传的AbsSavedState$1给HorizontalScrollView，无奈去翻源码：

@OverrideprotectedvoidonRestoreInstanceState(Parcelablestate){if(mContext.getApplicationInfo().targetSdkVersion<=Build.VERSION_CODES.JELLY_BEAN_MR2){//SomeoldappsreusedIDsinwaystheyshouldn'thave.//Don'tbreakthem,buttheydon'tgetscrollstaterestoration.super.onRestoreInstanceState(state);return;}SavedStatess=(SavedState)state;super.onRestoreInstanceState(ss.getSuperState());mSavedState=ss;requestLayout();}

大概意思就是在Android API 18（4.2.2和4.4.2之间的一个版本）以前，不会保存ScrollView的滚动条位置，这个对我影响也不是很大，规避这个问题我能想到有如下两种：

将AndroidMainifest.xml中android:targetSdkVersion降为18以下（如果需要记录这个状态，可以在onSaveInstanceState中记录位置，onRestoreInstanceState中恢复就可以了）；

不让View保存状态：

android:saveEnabled="false"|setSaveEnabled(false)|不要给view设置id
