Android listview in scrollview, listview scroll when scrollview scrolled specific position

Question

I need Scroll Listview inside Scrollview.

Scrollview has two child view, Relative layout and Listview

And listview is using naver's PullToRefresh library .

I want two function

• When scroll-up, scroll about half of Relative layout, pass thru touch event to listview.
• When scroll-down, if listview showing first item, realative layout will showing fully. else relative layout must be fixed scroll only listview. And if user had over scroll, pull-to-refresh must be work.

I have example screenshot

    android:id="@+id/main_doc_scroll"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:scrollbars="none"
    android:fillViewport="true">
    <LinearLayout
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
        <include
            layout="@layout/main_page_top_scroll_items"
            android:layout_height="wrap_content"
            android:layout_width="match_parent"/>
        <com.handmark.pulltorefresh.library.PullToRefreshListView
            xmlns:ptr="http://schemas.android.com/apk/res-auto"
            android:id="@+id/main_doc_list"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"

solved.

I give up to use scroll view.

I using onScrollListener on Listview, change menu's marginTop realtime.
