I use this. Maybe it will help you. Can you please tell me what you wrote in rounded_bottom_shape?
<Buttonandroid:id="@+id/calculate_button"android:layout_width="fill_parent"android:layout_height="wrap_content"android:text="Calculate"android:background="#454545"android:padding="5dp"style="@style/CalcResultStyle"></Button>
