How to make a LinearLayout scrollable

After I start the activity I am unable to scroll down to see other buttons and options in the xml defined below.

Does anyone know how to make this scrollable?

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

<LinearLayout

 xmlns:android="http://schemas.android.com/apk/res/android"

 android:layout_height="wrap_content"

 android:layout_width="fill_parent"

 android:background="#000044"

 android:isScrollContainer="true"

 android:orientation="vertical">

 <TextView

  android:id="@+id/title"

  android:text="@string/title"

  android:layout_width="wrap_content"

  android:layout_height="wrap_content"

  android:textColor="#ffffff"/>

 <EditText

  android:id="@+id/editTitle"

  android:text=""

  android:layout_width="fill_parent"

  android:layout_height="wrap_content"/>

 <TextView

  android:id="@+id/description"

  android:text="@string/description"

  android:layout_width="wrap_content"

  android:layout_height="wrap_content"

  android:textColor="#ffffff"/>

 <EditText

  android:id="@+id/editDescription"

  android:text=""

  android:layout_width="fill_parent"

  android:layout_height="wrap_content"/>

 <TextView

  android:id="@+id/location"

  android:text="@string/location"

  android:layout_width="wrap_content"

  android:layout_height="wrap_content"

  android:textColor="#ffffff"/>

 <EditText

  android:id="@+id/editLocation"

  android:text=""

  android:layout_width="fill_parent"

  android:layout_height="wrap_content"/>

 <TextView

  android:id="@+id/startTime"

  android:text="@string/startTime"

  android:layout_width="wrap_content"

  android:layout_height="wrap_content"

  android:textColor="#ffffff"/>

 <DatePicker 

  android:id="@+id/DatePicker01" 

  android:layout_width="wrap_content" 

  android:layout_height="wrap_content" />

 <TimePicker 

  android:id="@+id/TimePicker01" 

  android:layout_width="wrap_content" 

  android:layout_height="wrap_content"/>

 <TextView

  android:id="@+id/endTime"

  android:text="@string/endTime"

  android:layout_width="wrap_content"

  android:layout_height="wrap_content"

  android:textColor="#ffffff"/>

 <DatePicker 

  android:id="@+id/DatePicker02" 

  android:layout_width="wrap_content" 

  android:layout_height="wrap_content" />

 <TimePicker 

  android:id="@+id/TimePicker02" 

  android:layout_width="wrap_content" 

  android:layout_height="wrap_content"/>

 <Button

  android:id="@+id/buttonCreate"

  android:text="Create"

  android:layout_width="wrap_content"

  android:layout_height="wrap_content"/>

</LinearLayout>

My class code is

package com.example.blah;



import android.app.Activity;

import android.os.Bundle;



public class example extends Activity {

    /** Called when the activity is first created. */

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

    }

}

The output is http://img265.imageshack.us/img265/7601/linearlayout.jpg
