RecyclerView调用notifyDataSetChanged()不起作用

1.由于线性布局LinearLayout 包裹的RecyclerView 使用了android:layout_weight="1" 属性  这时候notifyDataSetChanged  onBindViewHolder失效 ，RecyclerView外再包FrameLayout      android:layout_weight="1" 属性 用在FrameLayout上

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/white"
    android:orientation="vertical">

    <com.xag.factory.operation.v4v2.wigdet.view.TopBarView
        android:id="@+id/top_bar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_constraintTop_toTopOf="parent"
        app:topbar_bg="@color/white"
        app:topbar_title_text="一键检测" />

    <View
        android:layout_width="match_parent"
        android:layout_height="0.5dp"
        android:background="@color/basecompat_divider" />


    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_marginTop="@dimen/dp_10"
        android:layout_weight="1">

        <androidx.recyclerview.widget.RecyclerView
            android:id="@+id/rv_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_marginStart="@dimen/dp_12"
            android:layout_marginEnd="@dimen/dp_12"
            android:background="@drawable/operation_shape_white_round_outline"
            android:minHeight="168dp"
            android:padding="@dimen/dp_12" />

    </FrameLayout>

    <TextView
        android:id="@+id/btn_start_detection"
        android:layout_width="match_parent"
        android:layout_height="@dimen/dp_46"
        android:layout_marginStart="@dimen/dp_12"
        android:layout_marginTop="@dimen/dp_10"
        android:layout_marginEnd="@dimen/dp_12"
        android:layout_marginBottom="@dimen/dp_12"
        android:background="@drawable/button_border_press_8dp"
        android:gravity="center"
        android:text="开始一键检测"
        android:textColor="@color/basecompat_green" />


</LinearLayout>
