Android之提示错误Can not perform this action after onSaveInstanceState

1 问题

主页面3个Fragment，在第三个Fragment里面开启了Activity之后，然后想跳到第一个Fragment代码如下

/*** 展示Fragment*/private fun showFragment(fragment: Fragment) {if (currentFragment !== fragment) {val transaction: FragmentTransaction = supportFragmentManager.beginTransaction()transaction.hide(currentFragment)currentFragment = fragmentif (!fragment.isAdded) {transaction.add(R.id.mainFrameLayout, fragment).show(fragment).commit()} else {transaction.show(fragment).commit()}}}

然后奔溃错误提示如下

    java.lang.IllegalStateException: Can not perform this action after onSaveInstanceStateat androidx.fragment.app.FragmentManagerImpl.checkStateLoss(FragmentManagerImpl.java:1536)at androidx.fragment.app.FragmentManagerImpl.enqueueAction(FragmentManagerImpl.java:1558)
