Recycler view is not scroling

Question

I have a Recycler View inside a Viewpager that is inside a NestedScroll View

My layout is as follows

<CoordinatorLayout>
    <AppBarLayout>
        <CollapsingToolbarLayout>
            <Toolbar>
            </Toolbar>
        </CollapsingToolbarLayout>
    </AppBarLayout>
    <NestedScrollView>
        <ViewPager>
            <RecyclerView>
            </RecyclerView>
        </ViewPager>
    </NestedScrollView>
</CoordinatorLayout>

I have more contents inside the RecyclerView but the view is showing items items till the AppBarLayout is being scrolled.

How to make the recycler view scroll complete list?

Below are the screenshots of the View

Edit: Here is the XML

<android.support.design.widget.AppBarLayout

Answer 1

在setAdapter之前将这一行添加到RecylerView recyclerView.setNestedScrollingEnabled（true）;

Answer 2

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

Add this line in your recycler view xml

android:nestedScrollingEnabled="false"
