我用 viewPager2 在我的应用程序中 custom adapter 在布局上我用我的 viewpager2 在 linearLayout . 我设置了 height 以及 width 我的 viewpager2 至 matchParent ，我还将其设置为 matchParent 在java代码中，并设置 attachToRoot 至 false ，但当我使用应用程序时仍会出现此错误。我怎样才能解决这个问题？
这是我的布局：

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <View
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1" />

    <androidx.viewpager2.widget.ViewPager2
        android:id="@+id/vp_home"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="0.7"
        android:clipToPadding="false"
        android:paddingStart="20dp"
        android:paddingEnd="20dp"/>

    <View
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1" />

</LinearLayout>

这是我的viewpager2代码：

mAdapter = new adapter_vp2_home(getActivity(), ls);

    vp_home.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
    vp_home.setOrientation(ViewPager2.ORIENTATION_HORIZONTAL);

    vp_home.setAdapter(mAdapter);

这是日志：
