i have tried with a lot of answers here like here, here also and here too

as someone pointed to use NestedScrollView instead ScrollView and i tried that too, but with no luck. Any solutions?

Solution

  • I managed to solve a similar vertical scrolling problem in my ViewPager doing the following:

    1. I created a separate layout (content_event) with ViewPager:

      <RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

<android.support.v4.view.ViewPager
    android:id="@+id/viewPagerActivEvent"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:layout_behavior="@string/appbar_scrolling_view_behavior">

</android.support.v4.view.ViewPager>

</RelativeLayout>

    2. And created NestedScrollView enclosing preceding layout with "android:fillViewport" set to true:

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

    <include layout="@layout/content_event" >

</android.support.v4.widget.NestedScrollView>

    Maybe it's not quite right but worked for me:)
