Code:

<?xml version="1.0" encoding="utf-8"?>

You have to let your ScrollView occupy all of the screen space by changing its height to match_parent , then all content that is inside

match_parent : The View should take up the same space as your Parent View   (View Parent). In any dimension (height and / or width)

fill_parent : Same match_parent function, but was used in   android 2.1, when the update was made for 2.3, was discontinued in   use of match_parent.

wrap_content : The View should occupy only the space you need (height   and / or width) to display your information in the layout.

The attributes of ScrollView would look like this, occupying all space vertically, as well as horizontally:

android:layout_width="wrap_content"
android:layout_height="match_parent"
