錯誤：內容必須有一個ListView的id屬性android.R.id.list

Question

使用SherlockListFragment，我找不到我的錯誤在哪裏。我已經閱讀了關於這個主題的幾個Q/A，但沒有一個解決方案似乎糾正了我的問題。任何幫助將不勝感激。謝謝。

public class BuyFragTab extends SherlockListFragment { 

ArrayList<Bookinfo> bookArray; 
ListView bookLV; 
MyCustomAdapter adapter = null; 

//defines the Arraylist Bookinfo record layout 
//public class Bookinfo { 
public String titles[] = new String[]{"Bk 1", "Bk 2", "Bk 3", "Bk 4", "Bk 5", "Bk 6", "Bk 7", "Bk 8"}; 
public String authors[] = new String[]{"Tom", "Dick", "Harry", "Jack", "James", "Skip", "Jim", "June"}; 
public String status[] = new String[]{"Open", "Open", "Open", "Open", "Closed", "Closed", "Closed", "Closed"}; 
public static ArrayList<String> bkRecs; 

Context context; 


@Override 
public void onActivityCreated(Bundle savedInstanceState){ 

    System.out.println("onActivityCreated executed"); 

    bookArray = new ArrayList<Bookinfo>(); 
    for (int i=0; i<8; i++) { 
     Bookinfo bkRecs = new Bookinfo(titles[i], authors[i], status[i]); 
     bookArray.add(bkRecs); 
     System.out.println("bookArray =" + titles[i]); 
    } 

    //adapter = new MyCustomAdapter(getActivity(), android.R.id.list, bookArray); 
    adapter = new MyCustomAdapter(getActivity(), R.layout.buy_tbfrag, bookArray); 
    //adapter = new MyCustomAdapter(); 
    //ArrayAdapter<Bookinfo> adapter = new ArrayAdapter<Bookinfo>(getActivity().getBaseContext(), 
    //  R.layout.buy_tbfrag_list, bookArray); 
    bookLV.setAdapter(adapter); 
    super.onActivityCreated(savedInstanceState); 
} 


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

    View view = inflater.inflate(R.layout.buy_tbfrag_list, container, false); 

    //bookLV = (ListView)view.findViewById(R.id.list); 
    //bookLV = getListView(); 
    bookLV = (ListView)view.findViewById(android.R.id.list); 

    return view; 
} 
}

Answer 1

更換

adapter = new MyCustomAdapter(getActivity(), R.layout.buy_tbfrag, bookArray); 

與

adapter = new MyCustomAdapter(getActivity(), R.layout.list, bookArray); 

Answer 2

當你extending ListActivity那麼就沒有必要對它進行初始化，因爲如果您使用與@android一種觀點：在你的佈局ID /空ID，ListActivity會自動顯示該查看ListView是否爲空，否則將其隱藏。

setListAdapter(adapter);

相反

bookLV.setAdapter(adapter);

，然後清理項目並運行它！

Answer 3

變化

android:id="@+id/authorName" 

到

android:id="@android:id/authorName"
