方向变化时对话框片段消失

Question

我有一个显示视图的对话框片段。当我显示视图时，它工作正常。尽管当我从横向/纵向更改其方向时，反之亦然，对话框片段消失了。我尝试了一些建议，尽管没有奏效。

这是Dialog片段的精简版本，我添加了onSaveInstanceState以保存状态，并尝试在onCreateView中对其进行调用。虽然不起作用。 任何帮助解决此问题的建议将不胜感激。 吉姆

public class BalanceOverlay extends DialogFragment implements View.OnClickListener {



public BalanceOverlay() {
    // Empty constructor is required for DialogFragment
    // Make sure not to add arguments to the constructor
    // Use `newInstance` instead as shown below
}

public static BalanceOverlay newInstance(String title) {
    BalanceOverlay frag = new BalanceOverlay();
    Bundle args = new Bundle();
    args.putString("Balance - The Center of the Plate", title);
    frag.setArguments(args);
    return frag;
}
@Override
public void onDestroyView() {
    if (getDialog() != null && getRetainInstance()) {
        getDialog().setDismissMessage(null);
    }
    super.onDestroyView();
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
     bview=  inflater.inflate(R.layout.balance, container);

    //setRetainInstance(true);
    return bview;
}
@Override
public void onSaveInstanceState(Bundle savedInstanceState) {
    super.onSaveInstanceState(savedInstanceState);
    savedInstanceState.putLong("param", value);
}
@Override
public void onViewCreated(final View view, Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    if (savedInstanceState != null){
        value =  savedInstanceState.getLong("param");
    }
