            android:layout_height="fill_parent"
            android:orientation="horizontal"
            android:background="#2a2a2a"
         >
            <GridView 
                    android:id="@+id/grid_view"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:columnWidth="150dp"
                    android:numColumns="auto_fit"
                    android:horizontalSpacing="10dp"
                    android:verticalSpacing="10dp"
                    android:stretchMode="columnWidth"
                    android:gravity="center"></GridView>
            <Button 
                    android:id="@+id/button1" 
                    android:layout_width="wrap_content" 
                    android:layout_height="50dp" 
                    android:text="@string/cam_string" />

    </LinearLayout>

Change the orientation of your LinearLayout to vertical. I suspect you're not seeing the Button because the GridView takes up all horizontal space, then the LinearLayout adds the Button in a place off the screen that's not visible. You also may want to change the layout_height of the GridView to "0dip" and give it the `android:layout_weight=1' attribute so that it will fill all space except that taken up by the Button.
