In the activation of my application there is a list of events consisting of tasks. Tasks are separated by a separator, represented as a RelativeLayout.

<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="wrap_content"> <TextView android:layout_width="match_parent" android:layout_height="27dp" android:text="Separator" android:gravity="center_horizontal|center_vertical" android:paddingLeft="16dp" android:textSize="16sp" android:id="@+id/tvSeparatorName"/> </RelativeLayout>

I implemented a change of themes in the application. There was a difficulty in changing the color of the separator - in the light theme there should be one shade, in the dark one another.

  <color name="backgroundSeparatorLight">#e4f062</color> <color name="backgroundSeparator">#e16d07</color> <resources> <style name="AppThemeLight" parent="Theme.AppCompat.Light.NoActionBar"> <item name="colorPrimary">@color/primaryLight</item> <item name="colorPrimaryDark">@color/primaryDarkLight</item> <item name="colorAccent">@color/accentLight</item> <item name="background">@color/backgroundSeparatorLight</item> </style> <style name="AppTheme" parent="Theme.AppCompat.NoActionBar"> <item name="colorPrimary">@color/primary</item> <item name="colorPrimaryDark">@color/primaryDark</item> <item name="colorAccent">@color/accent</item> <item name="background">@color/backgroundSeparator</item> </style> </resources>

How to set the separator background correctly? I would be grateful for the help.

    It is necessary in the attr file to set your custom attribute, which will be responsible for the color. For example, the attribute will be as follows:

     <attr name="separator_color" format="color"/>

    Then you specify the value of this attribute in your topics:

     <resources> <style name="AppThemeLight" parent="Theme.AppCompat.Light.NoActionBar"> <item name="colorPrimary">@color/primaryLight</item> <item name="colorPrimaryDark">@color/primaryDarkLight</item> <item name="colorAccent">@color/accentLight</item> <item name="separator_color">@color/backgroundSeparatorLight</item> </style> <style name="AppTheme" parent="Theme.AppCompat.NoActionBar"> <item name="colorPrimary">@color/primary</item> <item name="colorPrimaryDark">@color/primaryDark</item> <item name="colorAccent">@color/accent</item> <item name="separator_color">@color/backgroundSeparator</item> </style> </resources>

    Now you can set the desired color depending on the topic. The important point is to indicate where to use this color. Example:

     <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="wrap_content"> <TextView android:layout_width="match_parent" android:layout_height="27dp" android:text="Separator" android:gravity="center_horizontal|center_vertical" android:paddingLeft="16dp" android:textSize="16sp" android:textColor="?separator_color" android:id="@+id/tvSeparatorName"/> </RelativeLayout>

    where the android: textColor = "? separator_color" attribute is substituted from your theme.
