Why is my button becoming smaller when i click on it!!

This sounds pretty awesome! (and probably really annoying)

Does it continually get smaller and smaller with every click? Or just smaller once and then stays that size?

My guess would be that your button xml attributes of: android:layout_width="match_parent" android:layout_height="wrap_content" are being changed. Basically if when you load the app the button has a large parent and then when you click the button, you change the parent (maybe because the parent is the textview above, I just finished the first android project). The second text is smaller than the first text and thus your button resizes based on the text size above it...

But that's just a guess! Please copy and paste your code in so we can better help :)

Does your button xml code look like this? (Note if you're not done then some attributes like background & textColor probably wont be the same but you can replacing your button xml with this, it shouldnt break anything AS LONG AS YOUR android:id IS THE SAME!) I'd check to make sure the layout_width and layout_height are the same as:

<Button
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="Show Another Fun Fact"
        android:id="@+id/showFactButton"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        android:background="@android:color/white"
        android:textColor="#ff51b46d"
        android:clickable="true" />
