1. recyclerview之中的item重复,也就是说一直调用 onCreateViewHolder ,不停地创建 item
原因尚未知,
笨拙的做法:重复的item,直接隐藏控件
2. recyclerview中item只显示一项
1.
<androidx.viewpager2.widget.ViewPager2
android:id="@+id/viewPager_book"
android:layout_width="match_parent"
android:layout_height="wrap_content" // 设置此处
/>
2. item布局中根布局也设置成android:layout_height="wrap_content"
