如何修复IllegalStateException:旋转后显示Dialogfragment时活动已被破坏 [英] How to fix IllegalStateException: Activity has been destroyed when showing Dialogfragment after rotation
本文介绍了如何修复IllegalStateException:旋转后显示Dialogfragment时活动已被破坏的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个DialogFragment，它只发出Volley请求并将数据填充到RecyclerView中.我正在通过片段启动(通过单击TextView链接)此对话框.首次启动对话框时，它将启动并执行应做的事情，没有任何障碍.
I have a DialogFragment that nothing but make a Volley request and populate the data to a RecyclerView. I am launching (via a click on TextView link) this dialog from a fragment. When the dialog is launched for the first time, it launches and does what it's supposed to do, no hitch.
然后，我旋转屏幕，再次启动对话框，然后呜呼！出现"IllegalStateException:活动已被破坏"的消息.
Then I rotate the screen, launch the dialog again, and whoosh! I am greeted with "IllegalStateException: Activity has been destroyed".
关于此错误的一件奇怪的事情是，我还在 DetailsFragment 内的适配器类的onBindViewHolder中启动了相同的DialogFragment，即使我将屏幕旋转了十次，该对话框也不会出现故障.
One weird thing about this error is that I am also launching this same DialogFragment in the onBindViewHolder of an adapter class inside DetailsFragment and even if I rotate the screen ten times, the same dialog opens glitchlessly.
这是堆栈跟踪，

try {
tagCatFragment.show(getChildFragmentManager(), "TagCatFragment");
} catch (IllegalStateException e) {
e.printStackTrace();
}
}
});
}
}
}
尝试过的解决方案:
我尝试了流行的 Marcus Forsell Stahre解决方案.
我在 DetailsFragment
@Override
public void onDetach() {
super.onDetach();
try {
Field childFragmentManager = Fragment.class.getDeclaredField("mChildFragmentManager");
childFragmentManager.setAccessible(true);
childFragmentManager.set(this, null);
} catch (NoSuchFieldException e) {
throw new RuntimeException(e);
} catch (IllegalAccessException e) {
throw new RuntimeException(e);
}
}
但这没用.
推荐答案
尝试将DialogFragment修改为此
Try modifying your DialogFragment to this
//allows the DialogFragment to automatically recreate itself upon rotation
@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
}
// reinitialize the listener if need be still in DialogFragment
@Override
public void onAttach(Activity activity) {
super.onAttach(activity);
Log.v(TAG, "onAttach");
try {
if (activity != null)
mTagCatPostClickedListener = (OnTagCatPostClickedListener) activity;
} catch (ClassCastException e) {
throw new ClassCastException(activity.toString()
+ " must implement OnTagCatPostClickedListener");
}
}
并最小化在DetailsFragment中创建的DialogFragment实例的数量
and minimize the number of DialogFragment instances created in the DetailsFragment
protected static TagCatFragment tagCatFragment;
private void parseJson(JSONObject jsonObject) {
//your json stuff here
if (tagCatFragment == null)
tagCatFragment = TagCatFragment.newInstance("xxx", "yyyy",
"Author");
button.setOnClickListener(
new OnClickListener() {
@Override
public void onClick(View arg0) {
try {
tagCatFragment.show(getChildFragmentManager(),
"TagCatFragment");
} catch (IllegalStateException e) {
e.printStackTrace();
}
}
});
}
不确定将mFragment实例保存在何处.
但是，您可能希望将数据持久保存在 onDestroy 方法.让我知道事情的后续.
Not sure where your saving the mFragment instance.
However you might want to persist your data in the DialogFragment's on onDestroy method. Let me know how it goes.
