When using the CoordinatorLayout my ScrollView has an incorrect size
Solution 1
The standard ScrollView is only meant to be used as a parent. You need to change the ScrollView to a android.support.v4.widget.NestedScrollView
.
An example can be seen in the reference documentation for AppBarLayout
.
Solution 2
NestedScrollView is just like ScrollView, but it supports acting as both a nested scrolling parent and child on both new and old versions of Android. Nested scrolling is enabled by default.
You can use a NestedScrollView within a parent ScrollView. NestedScrollView is used when there is a need for a scrolling view inside another scrolling view. This is where it is useful, when the system needs to decide which view to scroll.
Here is an example of NestedScrollView with CoordinatorLayout:
<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.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
<!-- Your scrolling content -->
</android.support.v4.widget.NestedScrollView>
<android.support.design.widget.AppBarLayout
android:layout_height="wrap_content"
android:layout_width="match_parent">
<android.support.v7.widget.Toolbar
...
app:layout_scrollFlags="scroll|enterAlways"/>
<android.support.design.widget.TabLayout
...
app:layout_scrollFlags="scroll|enterAlways"/>
</android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>

I'm using a ScrollView in a layout, and am attempting to use the new
CoordinatorLayout
from the design support library.My layout file looks like this:
<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"> <ScrollView android:layout_width="match_parent" android:layout_height="match_parent" app:layout_behavior="@string/appbar_scrolling_view_behavior"> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical"> ... </LinearLayout> </ScrollView> <android.support.design.widget.AppBarLayout android:layout_width="match_parent" android:layout_height="wrap_content"> <android.support.v7.widget.Toolbar ... /> </android.support.design.widget.AppBarLayout> </android.support.design.widget.CoordinatorLayout>
When testing this the scrollview only occupies part of the screen. What went wrong?
