Android 2.2 を対象とする Android 互換性ライブラリを使用しています。配列アダプターで ListFragment を使用すると正常に動作しますが、simpleCursorAdapter を使用するとクラッシュします。ListFragment のコードは次のとおりです。
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 は SqliteHelper を拡張したクラスです。うまくいかない理由がわかりません。以前は listActivity で動作していました。コンストラクターにフラグを追加しました。このフラグメントをインスタンス化すると、デバイスはアプリケーションが中断されたことを通知し、アプリケーションを閉じます。誰かが私が間違っていることを知っていますか?
前もって感謝します。
