Scrollview didn't work even If i use android:fillViewport="true"

        android:layout_height="match_parent"
        android:orientation="vertical">
    //Horizontal Recyclerview items
    <RecyclerView
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
    </RecyclerView>
    //vertical Recyclerview items
        <RecyclerView
            android:layout_width="match_parent"
            android:layout_height="match_parent"></RecyclerView>
    </LinearLayout>

</ScrollView>

Solution 1

You should use NestedScrollView instead. However you may need to write your own LayoutManager. Check out this SO Answer for more details

Solution 2

1. You need to use a custom layout manager to use recyclerview inside a scrollview.

2. You can remove the scrollview and make a header item in the vertical recyclerview which contain the horizontal recyclerview.

Also you should not use a recyclerview inside a scrollview. So think the second approach will be better.

Also you can can use Snap-RecyclerView-Utils. It has a linear layout manager for recyclerview inside a scroll view and an adapter which can help you make a header containing you horizontal recyclerview.

Solution 3

ScrollView can only have one child.
Remove your RelativeLayout and try again.

Apart from that android:layout_height in ScrollView should be set to wrap_content

Additionally I'm not quite sure, if it works, since in the Docs it is stated that

You should never use a ScrollView with a ListView, because ListView takes care of its own vertical scrolling. Most importantly, doing this defeats all of the important optimizations in ListView for dealing with large lists, since it effectively forces the ListView to display its entire list of items to fill up the infinite container supplied by ScrollView.

Maybe a NestedScrollView works since it is for

NestedScrollView is just like ScrollView, but it supports acting as both a nested scrolling parent and child on both new and old versions of Android. Nested scrolling is enabled by default.
