定稿光标错误

我试图关闭数据库光标但后来它说，因为我得到的回报光标已关闭游标对象非法呼叫的...定稿光标错误

Cursor getDB(String date) { 
    int idate = Integer.parseInt(date.substring(0, 2)) * 1000000 
      + Integer.parseInt(date.substring(3, 5)) * 10000 
      + Integer.parseInt(date.substring(6)); 

    ourHelper = new DbHelper(ourContext); 
    ourDatabase = ourHelper.getReadableDatabase(); 

    Cursor cursor = ourDatabase.rawQuery("SELECT * FROM " + DATABASE_TABLE 
      + " WHERE " + KEY_DATE + " = " + idate,// + 
                // " ORDER BY " 
                // + 
                // KEY_NAME 
                // + 
                // " ASC", 
      null); 
    if (cursor != null && cursor.getCount() > 0) 
     return cursor; 

    return null; 
}

&这是我如何使用我的回报我得到

我初始化它们作为

adapter = new MyAdapter1(Day_Book.this, ourCursor, false); 
adapter2 = new MyAdapter2(Day_Book.this, ourCursor2, false); 
case R.id.bShowDB: 
     db = new DB(Day_Book.this); 
     ourCursor = db.getDB(et1.getText().toString()); 
     adapter.changeCursor(ourCursor); 
     adapter2.changeCursor(ourCursor); 
     //ourCursor.close(); 
     db.close(); 
     lv1.setAdapter(adapter); 
     lv2.setAdapter(adapter2); 
     //ourCursor.close(); 
     break;

这是我得到的错误光标..

删除db.close（）;从您的交换机案件。

在onDestroy（）中执行此操作。

哼，你是两个不同的适配器设置相同的游标两次：

adapter.changeCursor(ourCursor); 
adapter2.changeCursor(ourCursor);

也许这就是问题的根源。

不..这不是一个原因，因为我在另一个文件中使用了两个游标..这也显示了同样的错误。 – user1984849

第二点：你有一个db.close。如果关闭数据库也关闭任何打开的光标，我不会感到惊讶。 – SylvainL
