NewsChannelAdapter里的动画错位

[xjf1128]

activity_news_channel里RecyclerView应该由FrameLayout包含：

<include layout="@layout/toolbar" />

<FrameLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recycler_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:clipChildren="false"
        android:clipToPadding="false"
        android:padding="8dp" />
</FrameLayout>
