应该是fragment实例的空指针问题，你把报错信息截图我，然后你可以在saveinstance里判断下底部tab我不是Null，是Null重新new，这个还不是所有手机都会有的，Android手机兼容性老问题

猿猿老师，我把截图发到给您qq了，我的QQ号是以164开头的。这里我也复制一下报错： AndroidRuntime: FATAL EXCEPTION: main Process: com.xhtl.megather, PID: 19365 java.lang.NullPointerException: Attempt to invoke virtual method 'void android.support.v4.app.Fragment.setNextAnim(int)' on a null object reference at android.support.v4.app.BackStackRecord.executeOps(BackStackRecord.java:773) at android.support.v4.app.FragmentManagerImpl.executeOps(FragmentManager.java:2580) at android.support.v4.app.FragmentManagerImpl.executeOpsTogether(FragmentManager.java:2367) at android.support.v4.app.FragmentManagerImpl.removeRedundantOperationsAndExecute(FragmentManager.java:2322)
