How to use RecyclerView inside NestedScrollView?

Question

How to use RecyclerView inside NestedScrollView? RecyclerView content is not visible after setting adapter.

UPDATE layout code updated.

<android.support.v4.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">

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

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:padding="@dimen/keyline_1">

    </RelativeLayout>

    <View
        android:id="@+id/separator"
        android:layout_width="match_parent"
        android:layout_height="1dp"
        android:background="#e5e5e5" />

    <android.support.v7.widget.RecyclerView
        android:id="@+id/conversation"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

</LinearLayout>

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

Answer 1

I have Viewpager and RecyclerView inside the NestedScrollView. After adding below lines

recyclerView.setNestedScrollingEnabled(false);
recyclerView.setHasFixedSize(false);

I solved slow scroll and scroll lag issue.

Answer 2

Try to use this library - https://github.com/serso/android-linear-layout-manager.

LayoutManager of the library makes RecyclerView wraps its contents. In this case RecyclerView will be "as big as inner views", so it will not have a scrollbars and user will use scrolling abilities of NestedScrollView. Therefore, it will not be ambiguous like "scrollable inside scrollable".

Answer 3

You can't use a recycler view within a nested scroll view. It's not intended to contain further scrollable views but it's because it's a child of a scrolling layout itself that you need the nested scrolling view. I had the same issue but in the end I moved my textview to be a headerview within the recyclerview, made the recyclerview a direct child of the coordinator layout and deleted the nested scroll view. Then all my problems were gone.

RecyclerView with NestedScrollView

    <android.support.v7.widget.RecyclerView
    android:id="@+id/rv"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior" />

Answer 5

Simply adding recyclerView.setNestedScrollingEnabled(false); before setAdapter itself worked for me. I didn't add app:layout_behavior="@string/appbar_scrolling_view_behavior" anywhere & didn't set any custom layout manager

<android.support.v4.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/white"
        android:orientation="vertical">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginLeft="15dp"
            android:layout_marginRight="15dp"
            android:orientation="vertical">

            <TextView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:textColor="@color/white"
                android:text="Some Text..."
                android:padding="15dp" />

        </LinearLayout>

        <LinearLayout
            android:orientation="vertical"
            android:padding="15dp"
            android:layout_marginTop="10dp"
            android:layout_width="match_parent"
            android:layout_height="wrap_content">

            <TextView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:text="Quick Links"
                android:textColor="@color/black"
                android:textStyle="bold"
                android:textAllCaps="true"
                android:paddingLeft="20dp"
                android:drawableLeft="@drawable/ic_trending_up_black_24dp"
                android:drawablePadding="10dp"
                android:layout_marginBottom="10dp"
                android:textSize="16sp"/>

            <View
                android:layout_width="fill_parent"
                android:layout_height="1dp"
                android:background="#efefef"/>

            <android.support.v7.widget.RecyclerView xmlns:android="http://schemas.android.com/apk/res/android"
                android:id="@+id/recyclerview"
                android:layout_width="match_parent"
                android:layout_height="match_parent" />
        </LinearLayout>

    </LinearLayout>

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

You can use android:fillViewport="true" to make NestedScrollView measure the RecyclerView. The RecyclerView will fill the remaining height. so if you want to scroll the NestScrollView, you can set the RecyclerView's minHeight.
