Android TwoWayView SetAdapter不允许设置适配器（HorizontalListView）

我试着用它。我的xml包含

<org.lucasr.twowayview.TwoWayView 
     xmlns:android="http://schemas.android.com/apk/res/android"
     xmlns:tools="http://schemas.android.com/tools"
     android:id="@+id/rewardListView"
     style="@style/TwoWayView"
     android:layout_marginTop="20dp"
     android:layout_width="fill_parent"
     android:layout_height="fill_parent"
     android:drawSelectorOnTop="false"
     tools:context=".RewardActivity" />

我发现TwoWayView中的setAdapter（android.widget.ListAdapter）无法转换为RewardListViewAdapter“”出现此错误

我们将非常感谢您的帮助

mRewardListView = (TwoWayView) findViewById(R.id.rewardListView);
adaptor = new RewardListViewAdaptor(mRewardList, this); 
mRewardListView.setAdapter(adaptor);
