在slideUppanellayout中运行viewpager的问题

Question

在将Viewpager包含在滑动面板中时遇到麻烦

    <com.sothree.slidinguppanel.SlidingUpPanelLayout
    xmlns:sothree="http://schemas.android.com/apk/res-auto"
    android:id="@+id/sliding_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="bottom"
    sothree:umanoPanelHeight="68dp"
    sothree:umanoShadowHeight="4dp">
    <include
        layout="@layout/slidet"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <include
        layout="@layout/activity_overlay_secondary"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

幻灯片布局在其中包含视图寻呼机，如下所示-

  <android.support.design.widget.TabLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:tabGravity="fill"
    app:tabMode="fixed"
    android:id="@+id/tabMode"
    app:tabIndicatorColor="@color/tabindicatorcolor"
    android:background="@color/trans"
    app:tabTextColor="@color/tabletextcolor"/>
<android.support.v4.view.ViewPager
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/viewpager">
</android.support.v4.view.ViewPager>

单独滑动效果很好，但是在滑动面板中却什么也没显示
