如何在NestedScrollView中使用RecyclerView

Question

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>

Answer 1

just enable nestedscrolling that will enable smooth scrollview.

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

Answer 2

在recyclerView中使用它

app:layout_behavior="@string/appbar_scrolling_view_behavior"

Answer 3

<LinearLayout
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">

    <FrameLayout
        android:id="@+id/review_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
       <ScrollView
          android:layout_width="fill_parent"
          android:layout_height="fill_parent"
          android:layout_weight="1" >
    <LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">
        <RecyclerView
            android:id="@+id/recycler_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent"/>
            </LinearLayout>
            </ScrollView>
        <include
            android:id="@+id/empty_view"
            layout="@layout/review_empty_view"
            android:visibility="gone" />
    </FrameLayout>
</LinearLayout>

</LinearLayout>

Try this...

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

Answer 5

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

Answer 6

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);

Answer 7

只需将“不可滚动”布局放在嵌套滚动视图之外

Answer 8

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);
