Textview - 最大长度不适用于椭圆

我正在尝试创建一个文本视图，以便如果字符数超过 22，则显示省略号“...”会出现。然而，这不适用于 maxLength。

    <TextView
        android:id="@+id/vh_fragnotifications_postedby"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="12sp"
        android:layout_marginTop="8dp"
        android:text="zz12345678901234567890aaaaaaaa"
        app:layout_constraintTop_toBottomOf="@+id/vh_fragnotifications_body"
        app:layout_constraintLeft_toLeftOf="@+id/vh_fragnotifications_body"
        app:layout_constraintRight_toLeftOf="@+id/vh_fragnotifications_dateposted"
        android:maxLines="1"
        android:ellipsize="end"
        android:maxLength="22"/>

如何在保持最大数字 22 的情况下显示省略号？

这是完整的布局：___________________________________________________

Try this

 <TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textSize="20sp"
    android:layout_marginTop="8dp"
    android:text="zz12345678901234567890aaaaaaaa"
    android:maxLines="1"
    android:ellipsize="end"
    android:maxEms="11"
    />
