尝试将MotionLayout
与RecyclerView
一起使用,
向上滚动时,应用崩溃并出现错误:
android.content.res.Resources $ NotFoundException:无法找到 资源ID#0xffffffff
片段布局代码为
<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代码为:
<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>

将android:nestedScrollingEnabled="false"
添加到您的recyclerView
为我工作。
答案 1 :(得分:0)
更改
<ConstraintSet android:id="@+id/expanded"
android:id="@+id/cardView"
到
<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>
答案 2 :(得分:0)
每个ConstraintSet
都应自己拥有Constraint
,并且您需要指定任意数量的Constraint
来更改场景,例如,如果您要同时移动A和B互动,您需要在一个ConstraintSet
此外,我不确定您要实现的目标,但是我认为您需要编写如下代码
<OnSwipe
app:dragDirection="dragUp"
app:touchAnchorId="@id/rv_list"
app:touchAnchorSide="top" />
这意味着您以rv_list
为目标来触发操作。

app:moveWhenScrollAtTop="@+id/rv_list"
app的标配:moveWhenScrollAtTop应该为布尔值。
