In RelativeLayout you are trying to set the background color twice. That won't work.

And in the first call...

    android:background="@android:color/#fff092b0."

should be...

    android:background="#fff092b0"

...or...

 android:background="@color/some_color"

...with...

    <color name="some_color">#fff092b0</color>

...in your colors.xml file.

Notice also you have a period at the end of the hex code. That won't help you either.

Thank You for reply and help.
