I have this layout:

 <android.support.v4.widget.NestedScrollView
    android:id="@+id/scrollview"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:id="@+id/content"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

            <--There is some layouts here-->
            <RecyclerView
                android:id="@+id/recycler_view"
                android:layout_width="match_parent"
                android:layout_height="match_parent"/>
    </LinearLayout>

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

It works well. I can scroll RecyclerView smoothly without scrolling parent view.

Now I have to put the RecyclerView inside a FrameLayout like this:

 <android.support.v4.widget.NestedScrollView
    android:id="@+id/scrollview"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:id="@+id/content"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">
 <--There is some layouts here-->
        <FrameLayout
            android:id="@+id/review_layout"
            android:layout_width="match_parent"
            android:layout_height="wrap_content">

            <RecyclerView
                android:id="@+id/recycler_view"
                android:layout_width="match_parent"
                android:layout_height="match_parent"/>

            <include
                android:id="@+id/empty_view"
                layout="@layout/review_empty_view"
                android:visibility="gone" />
        </FrameLayout>
    </LinearLayout>

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

Now I cannot scroll the RecyclerView smoothly. All I want is: scroll RecyclerView smoothly without scrolling parent view. What should I do?

EDIT: Here is my review_empty layout:

    <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="center"
    android:orientation="horizontal"
    android:padding="16dp">

    <ImageView
        android:layout_width="80dp"
        android:layout_height="80dp"
        android:src="@drawable/shopping_review_empty" />

    <android.support.v4.widget.Space
        android:layout_width="32dp"
        android:layout_height="0dp" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/shopping_no_review_message" />
</LinearLayout>

  • add this line recyclerView.setNestedScrollingEnabled(false); – Akash Jun 09 '17 at 09:21
  • @Akash I added. It helps to scroll the `RecyclerView` smoothly. But it scrolls my parent view too. I don't want the parent view to be scrolled – TOP Jun 09 '17 at 09:23
  • What you want to achieve using FrameLayout? – Akash Jun 09 '17 at 09:24
  • I want to add a new view called "empty view" on top of `RecyclerView`. So I added both of them to a `FrameLayout` – TOP Jun 09 '17 at 09:25
  • @TOP can you explain me for what purpose u use FrameLayout? – ND1010_ Jun 09 '17 at 09:26

  • @TOP did you mean by like any TextView or View? – ND1010_ Jun 09 '17 at 09:28
  • @ND1010_ You can see my second layout above. I included a "empty_view". It will be shown on top of `RecyclerView` in case there is no data – TOP Jun 09 '17 at 09:38
  • @TOP are load images in shopping_review_empty ImageView ? – ND1010_ Jun 09 '17 at 11:05

just enable nestedscrolling that will enable smooth scrollview. 

RecyclerView v = (RecyclerView) findViewById(...);
v.setNestedScrollingEnabled(false);

I am suggesting you to do like this. When you get Empty Data then just set Recycler View Visibility as Gone and set Empty View Visibility as Visible.

Here is Code : 

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/white"
android:fitsSystemWindows="true">

<android.support.design.widget.AppBarLayout
    android:id="@+id/appbar"
    android:layout_width="match_parent"
    android:layout_height="400dp"
    android:background="@color/bg"
    android:fitsSystemWindows="true"
    android:theme="@style/AppTheme.AppBarOverlay">

    <android.support.design.widget.CollapsingToolbarLayout
        android:id="@+id/collapsingToolbar"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fitsSystemWindows="true"
        app:contentScrim="?attr/colorPrimary"
        app:layout_scrollFlags="scroll|exitUntilCollapsed">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:gravity="center"
            android:orientation="vertical"
            app:layout_collapseMode="parallax">

            <FrameLayout

  • I have to use `NestedScrollView`. Because in Landscape screen, there is not enough space for the `RecyclerView`. There are some other layout before `RecyclerView` (I do not show them in above code). So I need the `NestedScrollView` to allow users to scroll screen to see full `RecyclerView` – TOP Jun 09 '17 at 09:33
  • Yes you can do this using NestedScrollView too.Just Add this line if you are using NestedScrollView. recyclerView.setNestedScrollingEnabled(false); – Akash Jun 09 '17 at 09:34
  • I added. It helps to scroll the `RecyclerView` smoothly. But it scrolls my parent view too. I don't want to scroll the parent view while scrolling `RecyclerView` – TOP Jun 09 '17 at 09:41
  • No. Parent view means the whole `LinearLayout` inside the `NestedScrollView`. It is the view with id = "content" in above layout – TOP Jun 09 '17 at 09:45
  • Inside any View in NestedScroll is Scrolling. have you put any Image to your Linear Layout? – Akash Jun 09 '17 at 09:47
  • Please see my updated questions. I added some comments in the layout code. You can see: there are some layouts before the `FrameLayout` – TOP Jun 09 '17 at 09:51
  • so you don't want that commented layout will be scroll? – Akash Jun 09 '17 at 09:52
  • Yes. I only want to scroll my `RecyclerView` smoothly without scrolling other views. – TOP Jun 09 '17 at 09:55

That may be a chance you loading images(static) in to ImageView can be slow your recyclerView.

Or Big size of image.

Try to run application on mobile have good size of RAM

Add fillViewport is true in NestedScrollView in xml file as below:

<android.support.v4.widget.NestedScrollView
            android:id="@+id/nestedScrollView"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:fillViewport="true"
            android:scrollbars="none">

And In your activity setNested scrolling false as below code

recycler_view.setNestedScrollingEnabled(false);

Just put your "not scrollable" layout outside the nested scroll view

All you have to do is use below line in your activity class:

ViewCompat.setNestedScrollingEnabled(recycler_view, false);

its compatible for lower versions also. and if you want to give compatible to API >21 only then use;

  recycler_view.setNestedScrollingEnabled(false);
