View inside scrollview doesn't scroll while scrolling recyclerview

Question

i have a recycler view which contains a lot of posts. while i scroll the recyclerview my frame layout doesn't scroll. it is fixed like a navigation bar. I want it to scroll as if it was part of the recyclerview. Here is my layout:

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#ffffff"
    tools:context=".HomePageFragment">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <FrameLayout
            android:id="@+id/status_frame"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"></FrameLayout>

        <androidx.recyclerview.widget.RecyclerView
            android:id="@+id/recycler"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            ></androidx.recyclerview.widget.RecyclerView>

   </LinearLayout>
</ScrollView>

i tried using nestedScrollView but it adds extra empty posts. I dont know why.

My frameLayout is the status part. which is another recyclerview itself.while scrolling the posts the statuspart doesn't scroll.

any screenshots would be helpful – user158 Sep 07 '19 at 16:57 — user158, Sep 07 '19 at 16:57
what you mean by status part? the dead pool circles? – user158 Sep 07 '19 at 17:12 — user158, Sep 07 '19 at 17:12
yes those deadpol circles. they are on top of the post – Qahar Sep 07 '19 at 17:14 — Qahar, Sep 07 '19 at 17:14
Do you want them to scroll vertically with posts? – user158 Sep 07 '19 at 17:15 — user158, Sep 07 '19 at 17:15

In order for status part to scroll with posts in the recyclerview, status part should also be an item in the recyclerview, so you need recyclerview with multiple view types for this case. Plase read: How to create recyclerview with multiple view types.

Just remove the Framelayout it's not necessary, when using recyclerviews with multiple view types.

Minor improvements

Remove the outer scrollview its unnecessary, since recyclerview by default is scrollable.

Edit:

In order for status part to be scrollable horizontally, status part item layout should contain a recyclerview where LinearLayoutManager orientation set to horizontal. Remember to implement the adapter class for the horizontal recyclerview also.

For you to get started with recyclerview with multiple view types, you may look at this tutorial.

You may also use library like Epoxy in this case.

The status part is another recyclerview which scrolls horizontally. while the post part scrolls vertically. is it possible to do using what you suggest? — Qahar, Sep 07 '19 at 17:55
