附加到底部的AdView不让我查看回收视图中的最后一项

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:ads="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <androidx.recyclerview.widget.RecyclerView
        android:id="@+id/recyclerView"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <com.google.android.gms.ads.AdView
        android:id="@+id/adView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        ads:adSize="BANNER"
        ads:adUnitId="your_ad_unit_id" />

</RelativeLayout>

RecyclerView recyclerView = findViewById(R.id.recyclerView);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
recyclerView.setHasFixedSize(true);
recyclerView.setAdapter(adapter);

// 设置RecyclerView的高度
int adViewHeight = adView.getMeasuredHeight(); // 获取AdView的高度
int recyclerViewHeight = recyclerView.getMeasuredHeight(); // 获取RecyclerView的高度
int newRecyclerViewHeight = recyclerViewHeight - adViewHeight; // 减去AdView的高度
recyclerView.getLayoutParams().height = newRecyclerViewHeight; // 设置新的RecyclerView高度

recyclerView.scrollToPosition(adapter.getItemCount() - 1);
