Button size changes after first click.

So still on this tutorial here: http://teamtreehouse.com/library/build-an-android-app/basic-android-programming/generating-a-random-number

It ends with him clicking the button and getting numbers 0-2. Everything works perfectly BUT when I click my button for some reason it retracts to the side. It wasn't doing this yesterday when I left it. I woke up to continue my lesson and it was just doing this.

I uploaded a small video of my experience here: http://youtu.be/8XUo6cdpfps

Any help much appreciated!

Code:

<RelativeLayout 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:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".FunFactsActivity" android:background="#ff59c272">

<TextView
    android:text="Did you know?"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textSize="26sp"
    android:id="@+id/didYouKnow"
    android:textColor="#78ffffff"
    android:layout_alignParentTop="true" />

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Ants stretch when they wake up in the morning."
    android:id="@+id/factTextView"
    android:textSize="24sp"
    android:textColor="#ffffffff"
    android:layout_centerVertical="true"
    android:layout_centerHorizontal="true" />

<Button
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="Show Another Fun Fact!"
    android:id="@+id/showFactButton"
    android:background="#ffffffff"
    android:layout_alignParentBottom="true"
    android:layout_alignLeft="@+id/factTextView"
    android:layout_alignStart="@+id/factTextView" />

</RelativeLayout>

Hello Ian,

I am a bit suspicious of these layout settings.

android:layout_alignLeft="@+id/factTextView"
android:layout_alignStart="@+id/factTextView"

Remove those and use the following instead.

android:layout_centerHorizontal="true"

I hope this helps.
