                    android:textColor="#999999"
                    android:textSize="12sp" />

        </RelativeLayout>

</RelativeLayout>

Try with `android:background="#E6E8E3"`. You can select color from [color picker](http://www.colorpicker.com/E6E8E3) and get the hex of it easily. — MysticMagicϡ, Sep 02 '14 at 05:57

Set the background color to #AARRGGBB where AA is the alpha channel. For example you could use #00000000 for the color or the short method: #ARGB so that would be #0000 Using the shorthand notation the values are each just used twice where #264C would be the same as #226644CC ...http://developer.android.com/reference/android/graphics/Color.html
