Android 12下配置ellipsize=middle的TextView用Subtitle1样式时长文件名后缀截断

在Android 12系统上可复现长文件名显示异常问题：竖屏场景下，当需要将文件名单行展示、且配置android:ellipsize="middle"属性时，为TextView设置android:textAppearance="?attr/textAppearanceSubtitle1"会导致文件名扩展名显示不全。

对应布局代码 #

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".FirstFragment">

    <TextView
        android:id="@+id/first_line_text"

        android:layout_marginStart="10dp"
        android:layout_marginEnd="10dp"
        android:ellipsize="middle"
        android:maxLines="1"
        app:layout_constraintWidth="true"
        android:text="RF_20210819NZ Herald - Breaking news, latest news, business, sport and entertainment - NZ Herald.url"
