android – ConstraintLayout在textview中切断文本

我有一个带有几个视图的ConsTraintLayout,由于某种原因,我的textview在句子末尾被截断. textview受限于左侧和顶部.它是tv_product_description textview.

<android.support.consTraint.ConsTraintLayout
    android:id="@+id/ll_product_holder"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginLeft="16dp"
    android:layout_marginRight="16dp"
    android:layout_marginTop="16dp"
    android:BACkground="@drawable/drawable_border"
    android:orientation="vertical">

    <com.facebook.drawee.view.SimpleDraweeView
        android:id="@+id/iv_product_image"
        android:layout_width="100dp"
        android:layout_height="100dp"
        android:layout_marginBottom="8dp"
        android:layout_marginLeft="9dp"
        android:layout_marginStart="9dp"
        android:layout_marginTop="13dp"
        app:layout_consTraintBottom_toBottomOf="parent"
        app:layout_consTraintLeft_toLeftOf="parent"
        app:layout_consTraintTop_toBottomOf="@+id/price_holder"
        fresco:actualImageScaleType="centerCrop"
        fresco:placeholderImage="@drawable/placeholder2"/>

    <TextView
        android:id="@+id/tv_product_id"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="9dp"
        android:layout_marginStart="9dp"
        android:layout_marginTop="13dp"
        android:text="@{historyItem.productID}"
        app:layout_consTraintLeft_toRightOf="@+id/iv_product_image"
        app:layout_consTraintTop_toBottomOf="@+id/price_holder"/>

    <TextView
        android:id="@+id/tv_product_description"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="9dp"
        android:layout_marginStart="9dp"
        android:ellipsize="end"
        android:maxLines="2"
        android:text="@{historyItem.productDescription}"
        app:layout_consTraintLeft_toRightOf="@+id/iv_product_image"
        app:layout_consTraintTop_toBottomOf="@+id/tv_product_id"/>

</android.support.consTraint.ConsTraintLayout>
