FragmentActivityから前後にナビゲーションを操作しているときに例外を受け取り、 ListView にカスタム ローダーからロードされたデータ (ローカルの sqlite データベースからロードされています) が含まれており、その処理方法がわかりません...
スタックトレースは次のとおりです。

mCartCursorAdapter.swapCursor(null);
このコード フラグメントの行で例外が発生します(CartFragmentActivity.java:412):
public void onLoaderReset(Loader<Cursor> loader) {
switch (loader.getId()) {
case LOADER_CART_LIST_ID:
mCartListCursorAdapter.swapCursor(null);
break;
case LOADER_CART_CONTENTS_ID:
mCartCursorAdapter.swapCursor(null);
break;
}
}
この例外を削除するには、ここで何ができますか?
