how to make a scroll view to scroll over another layout with the layout behind staying intact but behind scroll content

Question

如何使滚动视图滚动到另一个布局上，而后面的布局保持不变，但在滚动内容后面我的要求是应用程序的标题将保持固定，而如果其中的内容足够大可以滚动，则它下面的布局将滚动，请提供给我或建议任何解决此问题的方法

Answer 1

Try this:

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/black"
    android:orientation="vertical">

    <ScrollView
        android:id="@+id/scrollView1"
        android:layout_width="wrap_content"
        android:layout_height="100dp"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_marginTop="100dp">

        <LinearLayout
            android:layout_width="269dp"
            android:layout_height="match_parent"
            android:orientation="vertical">

           <!-- any no. of views here -->
        </Linearlayout>
    <ScrollView>
</Linearlayout>

Add this code to onCreate():

scrollView.getViewTreeObserver().addOnScrollChangedListener(new OnScrollChangedListener() {

                @Override
                public void onScrollChanged() {
                    Layout.setY(Layout.getY() + scrollView.getScrollY() - Layout.getY());


                }
            });

Every time the view is scrolls, the layout will move the opposite value. Which looks like it's not moving at all. Make sure all your views are inside the ScrollView.
