android - 在recyclerview滚动上隐藏一个小部件会留下空白

Question

我在屏幕顶部放置了一个自定义日历视图，当我尝试基于 recyclerview 滚动隐藏该小部件时，该小部件会留下一个空屏幕，如下图所示

上面的calendarView留下了这样的空白

这是我的 fragment.xml 的代码

    <?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    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"
    android:background="@drawable/gradient_background"
    android:orientation="vertical"
    tools:context=".employer.AttendedFragment">

        <com.shrikanthravi.collapsiblecalendarview.widget.CollapsibleCalendar
            android:id="@+id/calendar_view"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:buttonLeft_drawableTintColor="@android:color/white"
            app:buttonRight_drawableTintColor="@android:color/white"
            app:expandIconColor="@color/itemColorDefault"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent"
            app:layout_scrollFlags="scroll|enterAlways"
            app:primaryColor="@color/colorPrimary"
            app:selectedItem_background="@drawable/circle_white_solid_background"
            app:selectedItem_textColor="@color/colorPrimary"
            app:textColor="@android:color/white"
            app:todayItem_background="@drawable/circle_white_stroke_background"
            app:todayItem_textColor="@android:color/white">

        </com.shrikanthravi.collapsiblecalendarview.widget.CollapsibleCalendar>

    <android.support.v7.widget.RecyclerView
        android:id="@+id/attendance_recyclerview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"
        android:clipToPadding="false">

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

</LinearLayout>

这就是我隐藏视图的方式

 @Override
            public void onHide() {
                mCalendarView.animate().translationY(-mCalendarView.getHeight()).setInterpolator(new AccelerateInterpolator(2));
            }

            @Override
            public void onShow() {
                mCalendarView.animate().translationY(0).setInterpolator(new DecelerateInterpolator(2));
            }

请让我知道如何在滚动 recyclerView 时删除该空白区域

添加动画侦听器，在您的动画完成后将日历视图的可见性设置为 GONE。
