Did not understand the question, you might consider uploading some images and giving us links to them. Only thing I can tell is that you must avoid using px when indicating any dimensions. This will make your views look different on every device, that you probably don't want.

use dip instead of px and sp.

Your xml will be

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent" 
  android:id="@+id/TheSplashLayout"
  android:layout_gravity="center"
   android:background="@drawable/splashmodified"
  >
    <ImageView 
        android:layout_width="60dip" 
        android:layout_height="60dip" 
        android:id="@+id/SplashImageView"

        android:layout_marginTop="120dip"
        android:layout_marginLeft="55dip"
        android:background="@drawable/a_thumb"
        />


    <Button 
         android:text="SUBMIT" 
         android:id="@+id/submitt"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content" 
         android:layout_marginLeft="75dip"
         android:layout_marginTop="300dip"
        />
</RelativeLayout>
