I solved my problem. I had to rearrange my code to get it working. Now the lyout refreshes on on reaching the top of the screen.

<RelativeLayout
    android:id="@+id/rel"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        app:layout_collapseMode="pin"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

    <android.support.v4.widget.SwipeRefreshLayout
        android:id="@+id/swipe_container"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/toolbar">

        <android.support.v7.widget.RecyclerView
            android:id="@+id/recycler"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_below="@id/swipe_container"
            android:scrollbars="vertical" />

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

Use setOnRefreshListener method of SwipeRefreshLayout

upload_swipe_refresh_layout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
        @Override
        public void onRefresh() {

            webServiceCall();
            upload_swipe_refresh_layout.setRefreshing(false);
        }
    });

For keep refreshing

upload_swipe_refresh_layout.post(new Runnable() {
    @Override
    public void run() {
        upload_swipe_refresh_layout.setRefreshing(true);
    }
});
