ConstraintLayout ListView RTL有些行不是RTL

Question

在我的ListView上，有些行不是RTL对齐。在滚动、和重绘之后，线条是正确的。

我的项目版面：

<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/clFrontView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:paddingTop="10dp"
    android:paddingBottom="10dp"
    android:paddingLeft="16dp"
    android:paddingRight="16dp">

    <ImageView
        android:id="@+id/ivCircle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/circle"
        tools:ignore="ContentDescription"
        android:layout_marginTop="5dp"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintLeft_toLeftOf="parent" />

    <ImageView
        android:id="@+id/ivReminderType"
        android:layout_width="20dp"
        android:layout_height="20dp"
        android:layout_centerVertical="true"
        android:layout_centerHorizontal="true"
        tools:ignore="ContentDescription"
        app:layout_constraintTop_toTopOf="@id/ivCircle"
        app:layout_constraintBottom_toBottomOf="@id/ivCircle"

        app:layout_constraintLeft_toLeftOf="@id/ivCircle"
        app:layout_constraintRight_toRightOf="@id/ivCircle" />

    <de.hdodenhof.circleimageview.CircleImageView
        android:id="@+id/civContactImage"
        android:layout_width="42dp"
        android:layout_height="42dp"

        android:layout_height="15dp"
        app:layout_constraintEnd_toEndOf="@id/civContactImage"
        app:layout_constraintRight_toRightOf="@id/civContactImage"
        app:layout_constraintBottom_toBottomOf="@id/civContactImage"
        tools:ignore="ContentDescription"/>

    <TextView
        android:id="@+id/tvTextLine"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="center_vertical"
        tools:text="Line of Text"
        android:textSize="18sp"
        android:maxLines="2"
        app:layout_constraintLeft_toRightOf="@id/ivCircle"
        app:layout_constraintStart_toEndOf="@id/ivCircle"
        android:layout_marginLeft="16dp"
        android:layout_marginStart="16dp"/>

    <TextView
        android:id="@+id/tvTextLine2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="center_vertical"
        android:textSize="16sp"
        android:visibility="gone"
        app:layout_constraintStart_toStartOf="@id/tvTextLine"
        app:layout_constraintLeft_toLeftOf="@id/tvTextLine"
        app:layout_constraintTop_toBottomOf="@id/tvTextLine" />

    <TextView
        android:id="@+id/tvTime"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="center_vertical"
        tools:text="Wed, 01.05.2018 10:10"
        android:textColor="#FF909090"
        android:textSize="12sp"
        android:drawablePadding="5dp"
        app:layout_constraintStart_toStartOf="@id/tvTextLine"
        app:layout_constraintLeft_toLeftOf="@id/tvTextLine"
        app:layout_constraintTop_toBottomOf="@id/tvTextLine2" />

    <TextView
        android:id="@+id/tvRepeat"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="center_vertical"
        tools:text="Every 2nd Friday"
        android:textColor="#FF909090"
        android:textSize="12sp"
        android:drawablePadding="5dp"
        app:layout_constraintStart_toStartOf="@id/tvTextLine"
        app:layout_constraintLeft_toLeftOf="@id/tvTextLine"
        app:layout_constraintTop_toBottomOf="@id/tvTime" />

</android.support.constraint.ConstraintLayout>

第一开始--看起来是这样的，第一行不是RTL：

​

在向下滚动并再次向上滚动到顶部之后，这是正确的：

​

build.gradle依赖关系：

implementation 'com.android.support.constraint:constraint-layout:1.1.2'

这些变化可能会奏效：

试试这个也许能解决问题。有一些小的测试更改--您可以根据需要删除它们--首先，我已经将工具:text更改为android:text，以便显示虚拟data.Secondly，两个名为icivCircleSmall和data.Secondly的图像视图--我只为测试目的放置了两个默认图像--所以请更改它。此外，还有一个名为icivCircleSmall的图片视图，我不知道它应该放在哪里，所以我没有编辑为它编写的任何代码。下面是xml的编辑代码。
