我正在使用针对Android 2.2的Android兼容性库。如果我使用ListFragment与数组适配器，它工作正常，但如果我使用simpleCursorAdapter，它会崩溃。这是我的ListFragment代码：
public class Fragment1 extends ListFragment {
private SQLiteDatabase db;
private Cursor c;
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
DbManager dbm = new DbManager (getActivity(), "mainDb", null, 3);
db = dbm.getWritableDatabase();
c = db.rawQuery("SELECT * FROM navegacion", null);
c.moveToFirst();
ListAdapter adapter = new SimpleCursorAdapter( getActivity().getApplicationContext(), R.layout.list_item, c, new String[]{"texto"}, new int []{R.id.mainListText}, CursorAdapter.FLAG_REGISTER_CONTENT_OBSERVER);
setListAdapter(adapter);
}
}
DbManager是一个扩展SqliteHelper的类。我不明白为什么它不起作用。它曾经与listActivity一起使用。我甚至将标志添加到构造函数中。当我实例化这个片段时，设备会说应用程序已被中断并关闭它。有人知道我做错了吗？
先谢谢你。

答案 0 :(得分：3)
使用ArrayAdapter但不使用SimpleCursorAdapter的原因是因为SimpleCursorAdapter extends CursorAdapter，CursorAdapter 无法正常工作不包含名为_id的列。 _id列中的值应该是绑定到ListView的值。
此错误与兼容性库无关。
