Android Material Design Divider Color

Question

Following color UI application of Material design i want to use an divider for the white theme. Guide told me that divider have 12% of white color, but how i can define 12% of white color divider in xml layout file?

Answer 1

12% refers to the alpha channel. The max alpa is 255, and 12% of 255 is 31. Hex of 31 is 1F. So the color is #1FFFFFFF

Answer 2

You can also use the official color which is also used in the Settings app:

<View android:id="@+id/tile_divider"       android:layout_width="match_parent"       android:layout_height="1dp"       android:background="?android:attr/dividerVertical" /> 

The important line is:

android:background="?android:attr/dividerVertical"
