I have a LinearLayout view that I am trying to add a divider to so that it looks exactly the same as the default ListView control. I am trying to replicate the edit contact within the default Android (Nexus S 2.3.3) Contacts app and I believe a LinearLayout would be best for performance.
I am using the code to replicate the divider as shown below:
<View android:id="@+id/Separator" android:layout_width="fill_parent" android:layout_height="?android:attr/dividerHeight" android:background="?android:attr/divider"/>
How can I access the default divider color or drawable and also the divider height? I would like this to match the ListViews I have setup, so using the Android system attributes would be best I think. The above code crashes as shown below so I assume I can’t access those attributes or am going about this incorrectly.

This is how it’s done in Android source code
<View android:id="@+id/Separator" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="?android:attr/listDivider" />
The source of Magician Knowledge must be https://developer.android.com/reference/android/R.attr.html
public static final int listDivider:
The drawable for the list
divider. Must be a reference to another resource, in the form
“@[+][package:]type:name” or to a theme attribute in the form
So all I have to do type in that site search bar – “drawable for the list divider” or just “divider”
