FragmentManager is already executing transactions

Posted 2021-06-29 安果移不动

    java.lang.IllegalStateException: FragmentManager is already executing transactions
        at androidx.fragment.app.FragmentManagerImpl.ensureExecReady(FragmentManagerImpl.java:14)
        at androidx.fragment.app.FragmentManagerImpl.execSingleAction(FragmentManagerImpl.java:2)
        at androidx.fragment.app.BackStackRecord.commitNowAllowingStateLoss(BackStackRecord.java:2)

 

原因 由于在Fragment中调用了

 方法导致的 

解决方案替换为 

getChildFragmentManager

即可

        FragmentManager fm = getChildFragmentManager();
        FragmentTransaction fragmentTransaction = fm.beginTransaction();
