Smooth scroll textview

Question

How can I make a smooth scroll of a textview in my application? This is a example of a main.xml similar to mine:

<?xml version="1.0" encoding="utf-8"?>
<RadioGroup xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

<TextView
    android:id="@+id/textView5"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:layout_marginTop="10dp"
    android:text="ANDROID APPLICATION INFO"
    android:textAppearance="?android:attr/textAppearanceLarge"
    android:textColor="#FF8000"
    tools:ignore="HardcodedText" />

<RadioButton
    android:id="@+id/radio_english"
    android:layout_width="201dp"
    android:layout_height="55dp"
    android:onClick="onRadioButtonClicked"
    android:text="English"
    tools:ignore="HardcodedText" />

<RadioButton
    android:id="@+id/radio_it"
    android:layout_width="200dp"
    android:layout_height="55dp"
    android:onClick="onRadioButtonClicked"
    android:text="Ita"
    tools:ignore="HardcodedText" />

<TextView
    android:id="@+id/AndroidInfo"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="Android Info.:"
    tools:ignore="HardcodedText" />

<TextView
    android:id="@+id/Ainfo"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    tools:ignore="SelectableText"
    android:text="blablablablabla blablablabla blablablablabla blablablabla `blablablablabla blablablabla blablablablabla blablablabla blablablablabla blablablabla" />`

</RadioGroup>

The Ainfo textview is that I want to make scrollable. But with a smooth scroll. I tried different ways but everything I tried was result a not smooth scroll. Any tips to di it? Don't take consider to the functionally because is an example.. Just want to understand how make the scroll smooth.

You want something like this?

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
tools:context=".MainActivity$DummySectionFragment" xmlns:app="http://schemas.android.com/apk/res/com.threesixtydgreen">

<ScrollView
    android:id="@+id/horizontalScrollView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_alignParentTop="true"
    android:scrollbars="none" >

        <TextView
            android:id="@+id/textView1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="blablablablabla blablablabla blablablablabla blablablabla `blablablablabla blablablabla blablablablabla blablablabla blablablablabla blablablabla"
            android:textAppearance="?android:attr/textAppearanceLarge" />


</ScrollView>
