我的应用中有一个包含 3 个 fragment 的 Activity 。当按下第一个按钮时，会在 Activity 中调用一个方法，该方法会执行一些不相关的操作，然后调用 finish()。

这会在 fragment 上触发 onPause()，它会做更多不相关的事情，然后调用 super.onPause()。

应用程序然后加载它出现的旧 Activity(逻辑上遵循 View 堆栈)，并在 Fragment 上调用 onDestroyView() 时突然崩溃并出现以下异常:

尝试从主 Fragment 中删除 MapFragment 时似乎会发生该错误。我知道你不应该在 fragment 中包含 fragment ，但是代码在过去有效，无论如何也没有办法解决它。

@Override
public void onDestroyView() {
    SupportMapFragment f = (SupportMapFragment) activity.getSupportFragmentManager().findFragmentById(R.id.fragment_map);
    if (f != null) {
        activity.getSupportFragmentManager().beginTransaction().remove(f).commit();
    }
    super.onDestroyView();
}

我已经在 SO 上四处寻找解决方案(最值得注意的是 getting exception "IllegalStateException: Can not perform this action after onSaveInstanceState" )，但它们都不适用于我当前的问题。

最佳答案

以下代码对我有用。放在调用mapfragment的fragment中

@Override
public void onDestroy() {

    SupportMapFragment f = (SupportMapFragment) getActivity().getSupportFragmentManager().findFragmentById(R.id.mapView);
    if (f.isResumed()){ 
        getFragmentManager().beginTransaction().remove(f).commit();
    }

    super.onDestroy();
}

关于Android - 完成后无法销毁 Activity ，由 IllegalStateException : Can not perform this action after onSaveInstanceState 引起，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/17701079/
