ScrollView-Large number of items in single page.

What if you have to fit a large story in a page or fit 20-30 buttons, check-boxes in a page? Use a ScrollView to fit it there.

What we will do?
-> We will prepare an application with a page with lot of items and which scrolls down.

What we will need?

Adding ScrollView in activity_main.xml along with existing items.
Others remain same.

Step 1 : Create a new Project. Click on File->New_>Android Application Project.

Step 2 : Give a specific name to your Project and also a package name(optional).Here I prefer it to be ScrollDemo. Then click Next... till Finish and click finish.

Step 3 : In the activity_main.xml (res->layout folder), drag the ScrollView from the Palette as shown below. Then add different elements of your choice inside it.

activity_main.xml

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="240dp"
    android:orientation="vertical"
    tools:context=".MainActivity" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="252dp"\
        android:layout_alignParentLeft="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentTop="true"
        android:text="Android is a mobile operating system (OS) based on the Linux kernel and currently developed by Google.

"
        android:textAppearance="?android:attr/textAppearanceMedium" />

    <TextView
        android:id="@+id/textView2"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="Android is the most widely used mobile OS and, as of 2013, the highest selling OS overall.

        android:textAppearance="?android:attr/textAppearanceMedium" />

    <Button
        android:id="@+id/button1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
