應用中展示DialogFragment旋轉

Question

後崩潰，當我轉動我的設備而呈現出DialogFragment，我的應用程序崩潰：

這是我DialogFragment：

public class ActionsDialogFragment extends DialogFragment { 

    public interface ActionsDialogListener { 
     void onActionSelected(DialogFragment dialog, int position); 
    } 

    AlertDialog dialog; 
    ActionsDialogListener mListener; 

    @Override 
    public void onAttach(Activity activity) { 
     super.onAttach(activity); 
     try { 
      mListener = (ActionsDialogListener) activity; 
     } catch (ClassCastException e) { 
      throw new ClassCastException(activity.toString() 
        + " must implement ActionsDialogListener"); 
     } 
    } 

    @Override 
    public Dialog onCreateDialog(Bundle savedInstanceState) { 
     AlertDialog.Builder builder = new AlertDialog.Builder(getActivity()); 
     dialog = builder.create(); 
     return dialog; 
    } 

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

     CustomListAdapter cla; 
     cla = new CustomListAdapter(getActivity()); 
     ListView list = (ListView) view.findViewById(R.id.listViewActions); 
     final AlertDialog finalDialog = dialog; 
     list.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
      @Override 
      public void onItemClick(AdapterView<?> parent, View view, int position, long id) { 
       mListener.onActionSelected((DialogFragment) getParentFragment(), position); 
       Log.d(FileListActivity.TAG, "Dismissing dialog"); 
//    ActionsDialogFragment.this.dismiss(); 
       finalDialog.dismiss(); 
      } 
     }); 
     list.setAdapter(cla); 
     dialog.setView(view); 
     return view; 
    } 

    @Override 
    public void onDestroy() { 
     super.onDestroy(); 
     Log.d(FileListActivity.TAG, "ActionDialogFragment onDestroy()"); 
     dismiss(); 
//  dialog.dismiss(); 
    } 

    class CustomListAdapter extends ArrayAdapter<String> { 
    ... 
    } 

} 

錯誤說「無法執行此操作在onSaveInstanceState之後「。但我不知道InstanceState的保存位置。對我來說，可以關閉對話框並在旋轉後重新創建對話框。

任何想法發生了什麼問題？

編輯：

我DialogFragment在這樣的主要活動產生：

void showActionsDialog() { 
    actionsDialog = new ActionsDialogFragment(); 
    actionsDialog.show(getSupportFragmentManager(), "ActionsDialogFragment"); 
} 

編輯2：

以防萬一，這一點很重要。這是我的主要活動的onDestroy()方法：

public void onDestroy() { 
    super.onDestroy(); 
    Log.d(TAG, "FileListActivity onDestroy()"); 
    if (exifReadingDialog != null) { exifReadingDialog.dismiss(); } 
    dataFragment.mRetainedCache = mMemoryCache; 
    dataFragment.setData(mediaFolder); 
} 

編輯3：

一些額外的想法：在這裏計算器很多人說，你應該在一個DialogFragment請使用onCreateDialog或onCreateView。也許這是我的問題。但是，如果我刪除onCreateDialog和dialog變量，解僱不再有效。到目前爲止，我使用此解決方案：Cannot get DialogFragment to dismiss programatically（只是關閉對話框，但拍擊旋轉）

Answer 1

同時，我已經嘗試了很多東西。我將ActionsDialogFragment更改爲this tutorial。

但我認爲真正的錯誤是在我的自定義ListAdapter。我改變了這部分

public @NonNull View getView(int position, View view, @NonNull ViewGroup parent) { 
    LayoutInflater inflater = getLayoutInflater(null); 

到

public @NonNull View getView(int position, View view, @NonNull ViewGroup parent) { 
    LayoutInflater inflater = ((Activity)context).getLayoutInflater(); 

現在我可以解僱DialogFragment簡單​​和應用程序不轉動之後再崩潰。

所以我應該在我的問題中發佈完整的課程。還是要謝謝你的幫助！

Answer 2

我認爲這個問題SI說的onDestroy調用片段事務提交的父活動和onSavedInstance有在此之後不能做被調用並且在onDestroy之前完成。你真的需要解僱onDestroy（）嗎？

Answer 3

由於Alert dialog在您的活動被破壞時正在運行，您會看到「泄漏窗口」異常。當活動被銷燬

你應該解僱對話框試試這個：

@Override 
protected void onDestroy() { 
    try { 
     if (dialog!= null && dialog.isShowing()) { 
      dialog.dismiss(); 
     } 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } 
    super.onDestroy(); 
} 

而且在setOnItemClickListener關閉對話框第一

list.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
     @Override 
     public void onItemClick(AdapterView<?> parent, View view, int position, long id) { 

      if (finalDialog != null && finalDialog.isShowing()) { 
        finalDialog.dismiss(); 
      } 
      mListener.onActionSelected((DialogFragment) getParentFragment(), position); 
      Log.d(FileListActivity.TAG, "Dismissing dialog"); 
    //  ActionsDialogFragment.this.dismiss(); 
     } 
    });
