尝试使用MotionLayoutwith RecyclerView,

向上滚动时,应用程序因错误而崩溃:

android.content.res.Resources$NotFoundException:找不到资源 ID #0xffffffff

片段布局代码是

<android.support.constraint.motion.MotionLayout
    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"
    app:layoutDescription="@xml/collapsing_config_order_details"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    ...

<android.support.v7.widget.CardView
        android:id="@+id/cardView"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginTop="8dp"
        app:layout_constraintEnd_toEndOf="@+id/tv_delivery_type"
        app:layout_constraintStart_toStartOf="@+id/imageView15"
        app:layout_constraintTop_toBottomOf="@+id/view4">

     ...

</android.support.v7.widget.CardView>

<android.support.v7.widget.RecyclerView
        android:id="@+id/rv_list"
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:layout_marginBottom="8dp"
        android:layout_marginTop="8dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="@+id/cardView"
        app:layout_constraintStart_toStartOf="@+id/cardView"
        app:layout_constraintTop_toBottomOf="@+id/cardView" />

</android.support.constraint.motion.MotionLayout>

和 layoutDescription 代码是:

<MotionScene xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <Transition
        app:constraintSetEnd="@id/collapsed"
        app:constraintSetStart="@id/expanded">

        <OnSwipe
            app:dragDirection="dragUp"
            app:touchAnchorSide="top"
            app:moveWhenScrollAtTop="@+id/rv_list" />

    </Transition>

    <ConstraintSet android:id="@+id/expanded"
            android:id="@+id/cardView"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_marginTop="8dp"
            app:layout_constraintEnd_toEndOf="@+id/tv_delivery_type"
            app:layout_constraintStart_toStartOf="@+id/imageView15"
            app:layout_constraintTop_toBottomOf="@+id/view4" />
    </ConstraintSet>

    <ConstraintSet android:id="@+id/collapsed">
    <Constraint
            android:id="@+id/cardView"
            android:layout_width="0dp"
            android:layout_height="1dp"
            android:layout_marginTop="8dp"
            app:layout_constraintEnd_toEndOf="@+id/tv_delivery_type"
            app:layout_constraintStart_toStartOf="@+id/imageView15"
            app:layout_constraintTop_toBottomOf="@+id/view4" />
    </ConstraintSet>

</MotionScene>

app:moveWhenScrollAtTop="@+id/rv_list"

app:moveWhenScrollAtTop 的值应该是布尔值。

添加android:nestedScrollingEnabled="false"到您的recyclerView

为我工作。

每个都ConstraintSet应该有Constraint自己,你需要指定尽可能多Constraint的场景来改变场景,比如如果你想通过一个交互来移动 A 和 B,你需要在一个交互中指定它们ConstraintSet

另外,我不确定您要实现什么,但我认为您需要编写如下代码

<OnSwipe
        app:dragDirection="dragUp"
        app:touchAnchorId="@id/rv_list"
        app:touchAnchorSide="top" />

这意味着您的目标rv_list是触发操作。

改变

<ConstraintSet android:id="@+id/expanded"
            android:id="@+id/cardView"

<ConstraintSet android:id="@+id/expanded" >
<Constraint android:id="@+id/cardView"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginTop="8dp"
        app:layout_constraintEnd_toEndOf="@+id/tv_delivery_type"
        app:layout_constraintStart_toStartOf="@+id/imageView15"
        app:layout_constraintTop_toBottomOf="@+id/view4" />
</ConstraintSet>
