Question

使用import base64 def main(dict): binary = get_object_storage_file('data', 'raw.bin') return {'data':base64.base64encode(binary)}和BottomNavigationView实施viewpager。每个导航视图都是第一个片段中的片段（＆＃34; NewsFeedFragment＆＃34;）我想使用{{1}附加一个viewpager。结果正确但片段内容与父tablayout重叠。

Home.xml

tablayout

NewsFragment.xml

toolbar

这是我得到的结果。

Map view is just a view that you want to collapse on scroll replace with your widget


     <com.google.android.gms.maps.MapView
            android:id="@+id/mapView"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:scaleType="centerCrop"
            app:layout_collapseMode="parallax" />

Widget that you want to display after collapse


    <android.support.design.widget.TabLayout
        android:id="@+id/tab_layout"
     app:layout_collapseMode="pin"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="?attr/colorPrimary"
        android:minHeight="?attr/actionBarSize"
        app:tabGravity="fill"
        app:tabMode="fixed"
        app:tabSelectedTextColor="@color/colorAccent"
        app:tabTextColor="#FFF" />


    <android.support.v4.view.ViewPager
        android:id="@+id/pager"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
    </android.support.design.widget.CollapsingToolbarLayout>

</android.support.design.widget.AppBarLayout>

     <android.support.v4.widget.NestedScrollView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:layout_behavior="@string/appbar_scrolling_view_behavior">
