android - ConstraintLayout - 将小部件连接到障碍问题

Question

我遇到了一个奇怪的问题:layout.xml

<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">

    <TextView
        android:id="@+id/textView4"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="wwwwwwwwwwwwwwwwwww" />

    <TextView
        android:id="@+id/textView5"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="wedwdwqefwerfwe"
        tools:layout_editor_absoluteX="0dp"
        tools:layout_editor_absoluteY="51dp" />

    <androidx.constraintlayout.widget.Barrier
        android:id="@+id/barrier"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:barrierDirection="end"
        app:constraint_referenced_ids="textView5,textView4"
        tools:layout_editor_absoluteX="411dp" />

    <Button
        android:id="@+id/button2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button"
        tools:layout_editor_absoluteX="275dp"
        tools:layout_editor_absoluteY="155dp" />
</androidx.constraintlayout.widget.ConstraintLayout>

我正在尝试将一个小部件连接到我的屏障。问题是，当我尝试将我的小部件的 END 与 barrier 连接时，没有连接(我做不到，我拖放没有成功).这是我尝试连接的图像，但这是不可能的。

your quetion is still unclear but as I understand you are not able to connect view with barrier right?
