Answer 1

Use android:fillViewport="true" in your Scrollview .

<ScrollView
    android:id="@+id/scrollView1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#fff"
    android:fillViewport="true" >

Try like this.

Answer 2

Actually it is the scrollView which is not getting full height and for that you should add the

android:fillViewport="true"

in your scrollview. You can just checkout my answer here

Android TableLayout inside ScrollView

and just try out this xml ,I have checked it on my machine:--

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/scrollView1"
android:layout_width="match_parent"

android:fillViewport="true" >
