To display a scrollable magazine article on the screen, you might use a that includes a separate TextView
for the article heading, another for the article subheading, and a third TextView
for the scrolling article text (see the figure below), set within a ScrollView
. The only part of the screen that would scroll would be the ScrollView
with the article text.
For example, if you want the subheading of an article to scroll along with the article even if they are separate TextView
elements, add a LinearLayout
to the ScrollView
as a single child View
as shown in the figure below, and then move the TextView
subheading and article elements into the LinearLayout
. The user scrolls the entire LinearLayout
which includes the subheading and the article.
When adding a LinearLayout
inside a ScrollView
, use match_parent
for the LinearLayout
android:layout_width
attribute to match the width of the parent ScrollView
, and use wrap_content
for the LinearLayout
android:layout_height
attribute to make it only large enough to enclose its contents.
Since ScrollView
only supports vertical scrolling, you must set the LinearLayout
orientation attribute to vertical (android:orientation="vertical"
), so that the entire LinearLayout
will scroll vertically. For example, the following XML layout scrolls the article
TextView
along with the article_subheading
TextView
:
A ScrollView
can contain only one child View
; however, that View
can be a that contains several View
elements, such as . You can nest a ViewGroup
such as LinearLayout
within the ScrollView
, thereby scrolling everything that is inside the LinearLayout
.
