问题描述
我正在做一个项目.我有一个布局，在view的顶部是view，在底部的是Scrollview.最初，布局将如下所示.
I am working a project. I have a a layout with a view at top and a Scrollview at the bottom of the view. Initially the layout will look like this.
向上滚动底部布局后.视图应平滑地更改下面的view.而且，如果我向下滚动，视图应该回到其先前的布局.
After I scroll up the bottom layout. The view should smoothly change the the below view. And if I scroll down the view should come back to its previous layout.
如您所见，textviews的位置和大小有所变化.我该如何实现?
As you can see there is a change in the position and size of the textviews. How can I achieve this ?
这是布局:

推荐答案
如João所述，使用折叠工具栏，您的代码应像这样并从此处
Using a Collapse Tool Bar as João said, your code should be like thisand getting my answer as base from here
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clipToPadding="false">
<android.support.design.widget.AppBarLayout
android:id="@+id/app_bar_layout"
android:layout_width="match_parent"
android:layout_height="210dp"
android:background="@color/WHITE">
<android.support.design.widget.CollapsingToolbarLayout
android:id="@+id/collapsing_toolbar_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:collapsedTitleTextAppearance="@style/TextAppearance.AppCompat.Widget.ActionBar.Title.Inverse"
app:expandedTitleMarginStart="72dp"
app:expandedTitleTextAppearance="@style/TextAppearance.AppCompat.Widget.ActionBar.Title.Inverse"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<Your Content>
<android.support.v7.widget.Toolbar
android:id="@+id/app_bar"
android:layout_width="match_parent"
android:layout_height="40dp"
app:layout_collapseMode="pin" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<include
layout="@layout/homescreen_scrollview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@id/layout_header_profile"
android:layout_marginTop="15dp" />
在<Your Content>上是您应该放置字符串的地方.抱歉，我无能为力了.您的科迪有点凌乱，真的很难理解.
On <Your Content> is the place where you should put your string.Sorry that I can't help more. Your Cody is a little messy and really hard to understand.
也许，如果您进行编辑，则仅保留重要的代码会有所帮助.
Maybe if you edit leaving only the important codes will help.
但是此库可以为您提供帮助.
But maybe this library can help you.
