Does anyone know why the scroll does not work ? I trying to make my page scrollable and can swipe to another tab. It allows me to swipe but not scrollable. I'm use most of the answer in Stack Overflow but none of them is worked in my case.

You have to add child views to linearLayout.

try something like this:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#FFFFFF"
android:orientation="vertical"
tools:context="com.example.samplestackoademo.MainActivity" >

<ScrollView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:background="#FFFFFF"
    android:fillViewport="true"
    android:orientation="vertical" >

    <AbsoluteLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical" >

        <TextView
