片段在片段對話框充氣拋出錯誤「片段沒有創建視圖」

Question

用戶點擊這帶來了其膨脹這樣的片段的片段對話的按鈕：

AlertDialog.Builder builder = new AlertDialog.Builder(getActivity()); 

     View view = getActivity().getLayoutInflater().inflate(
       R.layout.monday_fragment, null); 
     builder.setView(view).setTitle("Homework Due Monday") 
       .setNegativeButton("Dismiss", null); 

     AlertDialog dialog = builder.create(); 
     dialog.show(); 

這裏是佈局的XML指定（monday_fragment.xml）其中所述片段的引用被充氣在於：

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:id="@+id/container" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    tools:context=".MainActivity" 
    > 

    <fragment 
     android:id="@+id/monday_fragment" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:name="com.bernard.beaconportal.activities.schedule.daydialogfragments.MondayFragment" 
     android:layout_centerHorizontal="true"/> 

</RelativeLayout> 

在片段對話框中的片段然後在膨脹其OnCreateView自己的佈局：

@Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
      Bundle savedInstanceState) { 

     swipe = inflater.inflate(R.layout.day_homework_fragment, container, 
       false); 

     lView = (ListView) swipe.findViewById(R.id.listView1); 

     progress = (ProgressBar) swipe.findViewById(R.id.progress); 

     lView.setVisibility(View.GONE); 

     return swipe; 

    } 

這裏是在該片段中誇大了「day_homework_fragment.xml」佈局：

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical" 
    android:layout_gravity="center" 
    android:background="@color/light_background"> 

    <ProgressBar 
     android:id="@+id/progress" 
     android:layout_width="wrap_content" 
     android:layout_height="match_parent" 
     android:layout_gravity="center" /> 

    <ListView 
     android:id="@+id/listView1" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_alignParentBottom="true" 
     android:layout_alignParentLeft="true" 
     android:layout_alignParentRight="true" 
     android:layout_alignParentTop="true" 
     android:background="#ffffff" 
     android:divider="@null" 
     android:dividerHeight="0dp" 
     > 
    </ListView> 

      <TextView 
      android:id="@+id/emptyView" 
      android:layout_width="match_parent" 
      android:layout_height="match_parent" 
      android:text="As of now, no homework due this day" 
      android:padding="30dp" 
      android:textSize="16sp"/> 

</LinearLayout> 

這裏是它引發錯誤的日誌，我都試過這個post這post，我也沒有解決了這個問題。

編輯：我只是意識到，這隻在我從eclipse移動到Android Studio後纔開始發生。也許這跟它有關係？可能所有的片段引用都搞砸了？

Answer 1

我覺得這個代碼是犯罪嫌疑人：

View view = getActivity().getLayoutInflater().inflate(
      R.layout.monday_fragment, null); 

的inflate，第一個參數是XML文件名，而不是片段ID。也許你想要xml R.layout.day_homework_fragment來代替。

我知道這些ID很混亂。只有像findViewById（）這樣的方法指向一個UI ID。

Answer 2

你的日誌點到第10行是指這裏的XML聲明是一個問題，因爲碎片在第10行說的事實：

android:name="com.bernard.beaconportal.activities.schedule.daydialogfragments.MondayFragment" 

我會仔細這裏檢查此引用，看看它是否指向正確的地方，你已經保存了片段的Java類。

此外，檢查你的MondayFragment類，你正在擴展正確的片段類。換句話說，如果您使用支持庫，則需要擴展支持庫Fragment類而不是普通的Fragment類。

如果一切都失敗了，你總是可以以編程方式添加一個片段：http://developer.android.com/training/basics/fragments/fragment-ui.html

編輯：我看到你用下面的代碼目前膨脹你的XML：

View view = getActivity().getLayoutInflater().inflate(
       R.layout.monday_fragment, null); 

既然你無論如何都會在片段內膨脹它，你能不能只說：

View view = inflater.inflate(R.layout.monday_fragment, null, 
       false); 

Answer 3

兩件事情：

1. 檢查com.bernard.beaconportal.activities.schedule.daydialogfragments.MondayFragment是正確的軟件包名稱（路徑）

2. 在你monday_fragment.xml重命名android:id="@+id/monday_fragment"到android:id="@+id/monday_fragment1"。

   請參見下面的代碼：

   <Fragment 
       android:id="@+id/monday_fragment1" 
       android:layout_width="match_parent" 
       android:layout_height="wrap_content" 
       android:name="com.bernard.beaconportal.activities.schedule.daydialogfragments.MondayFragment" 
       android:layout_centerHorizontal="true"/> 
   

Answer 4

我相信你有調試包com.bernard.beaconportal.activities.schedule.daydialogfragments.MondayFragment本身。遷移到Android Studio後，UI參考可能無效。一種簡單的調試方法是在OnCreateView()中刪除代碼。

如果您將包導入爲jar文件，那麼這是一個不同的案例/問題。

Answer 5

你不能把片段放在標準AlertDialog內。您必須創建一個DialogFragment實現來將片段添加到對話框中。原因很簡單，因爲標準片段會嘗試將自己附加到相應活動的根窗口，而當根窗口上有單獨的窗口時，情況並非如此。 AlertDialog不能包含DialogFragment或甚至Fragment。嘗試將您的AlertDialog代碼更改爲DialogFragment實施。

Answer 6

爲什麼不使用對話框片段而不使用Alertdialog？它對於在活動範圍內調用某個爭議非常重要。對話框片段將具有所有生命週期方法，並且將有助於創建任何後續片段。

Answer 7

通過xml綁定片段通常會帶來負面的微妙後果。動態地做這件事。

改變你的monday_fragment。XML這樣的：

<?xml version="1.0" encoding="utf-8"?> 
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:id="@+id/container" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    > 

</FrameLayout> 

並更改該塊的代碼：

AlertDialog.Builder builder = new AlertDialog.Builder(getActivity()); 

View view = getActivity().getLayoutInflater().inflate(
     R.layout.monday_fragment, null); 

builder.setView(view).setTitle("Homework Due Monday") 
     .setNegativeButton("Dismiss", null); 

MondayFragment mondayFragment = new MondayFragment(); 
getFragmentManager().beginTransaction() 
        .replace(R.id.container, mondayFragment) 
        .commit(); 

AlertDialog dialog = builder.create(); 
dialog.show(); 

編輯：如果失敗，嘗試改變

getFragmentManager().beginTransaction() 
     .replace(R.id.container, mondayFragment) 
     .commit(); 

爲

getParentFragment().getChildFragmentManager().beginTransaction() 
      .replace(R.id.container, mondayFragment) 
      .commit(); 

---

編輯讓我們嘗試DialogFragment

請創建類DayHomeworkDialogFragment：

public class DayHomeworkDialogFragment extends DialogFragment { 

    public DayHomeworkDialogFragment() { 
    } 

    @Override 
    public Dialog onCreateDialog(Bundle savedInstanceState) { 


     LayoutInflater inflater = LayoutInflater.from(getActivity()); 
     View swipe = inflater.inflate(R.layout.day_homework_fragment, null); 

     lView = (ListView) swipe.findViewById(R.id.listView1); 
     progress = (ProgressBar) swipe.findViewById(R.id.progress); 
     lView.setVisibility(View.GONE); 



     AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(getActivity()) 
       .setView(swipe) 
       .setTitle("Homework Due Monday") 
       .setPositiveButton("Add", new DialogInterface.OnClickListener() { 
        @Override 
        public void onClick(DialogInterface dialog, int which) { 

        } 
       }) 
       .setNegativeButton("Dismiss", 
         new DialogInterface.OnClickListener() { 
          public void onClick(DialogInterface dialog, int whichButton) { 
           dialog.dismiss(); 
          } 
         } 
       ); 

     return alertDialogBuilder.create(); 
    } 
} 

，而不是這個

AlertDialog.Builder builder = new AlertDialog.Builder(getActivity()); 

     View view = getActivity().getLayoutInflater().inflate(
       R.layout.monday_fragment, null); 
     builder.setView(view).setTitle("Homework Due Monday") 
       .setNegativeButton("Dismiss", null); 

     AlertDialog dialog = builder.create(); 
     dialog.show(); 

使用，這一點：

FragmentManager fragmentManager = getFragmentManager(); 
DayHomeworkDialogFragment dayHomeworkDialogFragment = new DayHomeworkDialogFragment(); 
dayHomeworkDialogFragment.show(fragmentManager, "my_day_homework_fragment"); 

如果失敗，嘗試使用getCh ildFragmentManager（）而不是getFragmentManager（）
