问题是，在方向改变后，DialogFragment目标不在片段管理器中;所以重写onDestroyView（）并将setRetainInstance（true）设置为Dialogfragment并没有解决它!!
来自MyFragment.java的代码
public class MyFragment extends ListFragment {
//...
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode != Activity.RESULT_OK)
return;
if (requestCode == REQUEST_TO_DIALOG_FRAGMENT) {
//...
}
}
private void show_my_dialog_fragment(int index) {
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.addToBackStack(null);
DialogFragment fragment = MyDialogFragment.newInstance(index);
fragment.setTargetFragment(this, REQUEST_TO_DIALOG_FRAGMENT);
fragment.show(ft, null);
}
}
这来自MyDialogFragment.java
MyDialogFragment extends DialogFragment {
//...
private void sendResult(int resultCode) {
if (getTargetFragment() == null)
return;
getTargetFragment().onActivityResult(getTargetRequestCode(), resultCode, null);
}
}

答案 0 :(得分：0)
这取决于您使用的Android版本。在较低版本中没有childfragment manager。要解决这个问题，您可以在主片段的onpause（）（在oriantion更改之前调用）中删除此对话框，并在onresume（）中替换它（称为postoriantion已更改）
