Why isn't my FunFacts android app full screen?

Here is my dimens.xml:

<resources>
    <!-- Default screen margins, per the Android Design guidelines. -->
    <dimen name="activity_horizontal_margin">0dp</dimen>
    <dimen name="activity_vertical_margin">0dp</dimen>
</resources>

Here is the activity_fun_facts.xml:

<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="50dp"
    android:paddingRight="50dp"
    android:paddingTop="50dp"
    android:paddingBottom="50dp"
    tools:context=".FunFactsActivity"
    android:background="#ff5cca6b">

    <TextView
        android:text="Did you know?"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="24sp"
        android:textColor="#80ffffff"
        android:layout_alignParentTop="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="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:layout_centerVertical="true"
        android:layout_centerHorizontal="true"
        android:textSize="24sp"
        android:textColor="@android:color/white" />

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Show another Fun Fact"
        android:id="@+id/ShowFactButton"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        android:singleLine="false"
        android:textSize="18sp"
        android:background="@android:color/white" />

</RelativeLayout>

Here is the screenshot:

Update:

Here is the styles.xml file:

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="android:Theme.Holo.Light.Dialog.NoActionBar">
        <!-- Customize your theme here. -->
    </style>

</resources>

I think you should delete

Mainactivity.xml 
android:paddingLeft="50dp"
android:paddingRight="50dp"
android:paddingTop="50dp"
android:paddingBottom="50dp"

that code in your activity_fun_facts.xml

Hope that help.

But that was in the video (https://teamtreehouse.com/library/build-a-simple-android-app-new/creating-the-screen-layout/setting-padding)

Go to android Manifestfile file and added that

Manifest.xml 
<supports-screens
    android:smallScreens="true"
    android:normalScreens="true"
    android:largeScreens="true"
    android:anyDensity="true" />

and try to run the app. If that doesn't work I think its a emulator problem. You can make a new emulator with Ben Deitch in this workshop http://teamtreehouse.com/library/getting-started-with-the-android-emulator

And run your app in your new emulator.

Try that- Go to dimens.xml and change this

dimens.xml 
<dimen name="activity_horizontal_margin">0dp</dimen>
<dimen name="activity_vertical_margin">0dp</dimen>

to

dimens.xml 
<dimen name="activity_horizontal_margin">16dp</dimen>
<dimen name="activity_vertical_margin">16dp</dimen>

Let me have a look - just loading the Emulator, so I'll get back to you in about a week. ;-)

Is there a Theme issue here? I've not got a complete version of this app, unfortunately so I can't compare what you have with anything here.

What does the top of your fun_facts_activity file look like? I can't see that you've created a RelativeLayout. I can't see the id for it. Can you post the first few lines of code, please?

Fullscreen stuff is often defined in the theme - perhaps the later SDKs handle this differently than when the course was written.

Steve Hunter : Updated the code. Actually it was there, but the code wasn't formatted properly. Do you want me to add something else too??

I'm not sure what the issue is, to be honest - it would be helpful to have a git repository so I can replicate the issue at this end.

One thing, and I genuinely don't know if this makes any difference at all - it probably won't - but shouldn't the RelativeLayout have a line like android:id="@+id/realtiveLayout". I guess that would only matter if the ID was referred to somehwere.

Sorry I can't be much help on this one! It is a strange issue.

Steve.
