NestedScrollView + SwipeRefreshLayout + RecyclerView

layout.xml

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

    <android.support.v4.widget.NestedScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical"
            android:focusableInTouchMode="true"> <!-- Prevents scrolling location from being overriden by RecyclerView -->

            <TextView
                android:layout_width="match_parent"
                android:layout_height="200dp"
                android:gravity="center"
                android:text="Contents above RV"/>

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

        </LinearLayout>

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

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

Checklist

• recyclerView.setNestedScrollingEnabled(false) for smooth scrolling/fling
• layoutManager.setAutoMeasureEnabled(true) if RecyclerView does not render items.

Mine seems to take a lotta time to render recyclerView items, and sometimes doesn't render at all.

RecyclerView is not displaying all items

pull-up refresh invalid ....

gjkhgkj

@sam453 Yes, exactly.

Reason:
As NextedScrollView won't let recycle the items of RecyclerView & loads all the items in one shot, pull-up refresh won't work.

Workaround:
We need to manually/listen-to monitor the NestedScrollView's scrolling event & do the load-more-items thing in child's RecyclerView.
i.e., as soon the NestedScrollView scrolls to its last, callback the RecyclerView's adapter & load items.

👍
Cheers !!

Using same layout and scrolling is working but it's not smooth.

i think recyclerview height must be match_parent

i have horizontal and vertical scroll view and got many issues:

<androidx.core.widget.NestedScrollView
        android:id="@+id/scrollView"
        android:layout_width="match_parent"
        android:fillViewport="true"
        android:layout_height="match_parent">

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

            <androidx.recyclerview.widget.RecyclerView
                android:id="@+id/rcStory"
                android:layout_width="match_parent"
                android:layout_height="100dp"
                android:nestedScrollingEnabled="false"
                android:background="@color/red" />

            <com.jcodecraeer.xrecyclerview.XRecyclerView
                android:id="@+id/rcRecent"
                android:layout_width="match_parent"
                android:descendantFocusability="blocksDescendants"
                android:layout_weight="1"
                android:nestedScrollingEnabled="false"
                android:layout_height="match_parent"
                android:background="@color/mainGray" />
        </LinearLayout>
