From your previous post, I'm assuming you're using this library (https://github.com/umano/AndroidSlidingUpPanel).
This library requires that you have 2 children views. The first one being the main layout and the second one the actual sliding view. Now, your sliding view is just a placeholder, so you can place anything you want in there. If you want to add a ViewPager, this is how you can do it.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<SlidingUpPanelLayout
android:layout_width="match_parent"
android:layout_height="match_parent" >
<!-- Top Panel -->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent" >
</LinearLayout>
<!-- Sliding Panel -->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<android.support.v4.view.ViewPager
android:layout_width="match_parent"
android:layout_height="match_parent" >
</android.support.v4.view.ViewPager>
</LinearLayout>
</SlidingUpPanelLayout>
</RelativeLayout>
What we have here is the main layout of our Activity (RelativeLayout) and we're adding the SlidingPanelLayout
to it. Inside this Layout, we've defined our main layout to be a LinearLayout (Top Panel) and a second LinearLayout (Sliding Panel) which is the actual sliding view. Now, all we need to do is add a ViewPager to this sliding panel.
