StaleDataException与对话框

我想显示一个列表视图与名称从我的数据库中的对话框，但我不断收到StaleDataException。我知道这通常意味着我试图从一个封闭的游标的数据，但直到我得到的所有数据，所以我不明白为什么我收到此StaleDataException与对话框

d = new Dialog(this); 
d.setContentView(R.layout.dialog_layout); 
d.setTitle("Select Bowler"); 

ListView lv = (ListView)d.findViewById(R.id.dialog_list); 
Cursor c = getContentResolver().query(
    BowlersDB.CONTENT_URI, 
    new String[] { 
     BowlersDB.ID, BowlersDB.FIRST_NAME, BowlersDB.LAST_NAME 
    }, 
    null, 
    null, 
    BowlersDB.LAST_NAME + " COLLATE LOCALIZED ASC" 
); 

if (c.moveToFirst() && c != null) { 
    SimpleCursorAdapter adapter = new SimpleCursorAdapter(
     this, 
     R.layout.names_listview, 
     c, 
     new String[] { 
      BowlersDB.FIRST_NAME, BowlersDB.LAST_NAME 
     }, 
     new int[] { 
      R.id.bListTextView, R.id.bListTextView2 
     }, 
     0 
    ); 
    lv.setAdapter(adapter); 
    lv.setOnItemClickListener(new OnItemClickListener() { 

     @Override 
     public void onItemClick(AdapterView<?> arg0, View v, int position, long id) { 
      bowlerClickedID = id; 
      updateName(id); 
     } 
    }); 
    d.show(); 
} 
c.close();

错误

    Attempting to access a closed CursorWindow.

光标没有关闭

编辑：如果我注释掉c.close()行它工作正常，但我不能让光标打开，但我该怎么办？

在CursorAdapter不再需要之前，您无法关闭游标。所以，你可以在的onDestroy关闭它（）方法：

@Override 
public void onDestroy() { 
super.onDestroy(); 

ListView lv = (ListView) d.findViewById(R.id.dialog_list); 
((CursorAdapter) lv.getAdapter()).getCursor().close(); 
database.close(); 
}
