Android Holo Selected List Item Color

Question

Can someone tell me the corresponding color code of a selected list item in Holo? Also, what are the colors to generate a long press list item transition in Holo? I know the Holo colors are defined in colors.xml but I'm unsure which ones are used for the selection and long press list item transition. Thanks in advance.

Answer 1

If you have a look at Android's platform framework base, especially the themes.xml file, you will find the answer to your question:

https://github.com/android/platform_frameworks_base/blob/master/core/res/res/values/themes.xml

This file defines, amongst others, the following two Holo themes and its corresponding items:

Theme.Holo:

<style name="Theme.Holo">
    ...
    <item name="colorPressedHighlight">@color/holo_blue_light</item>
    <item name="colorLongPressedHighlight">@color/holo_blue_bright</item>
    ...
</style>

Theme.Holo.Light:

<style name="Theme.Holo.Light" parent="Theme.Light">
    ...
    <item name="colorPressedHighlight">@color/holo_blue_light</item>
    <item name="colorLongPressedHighlight">@color/holo_blue_bright</item>
    ...
</style>

I think these are the two colours you are looking for.
The colours are translated into the following hex codes:

<!-- A light Holo shade of blue -->
<color name="holo_blue_light">#ff33b5e5</color>

<!-- A really bright Holo shade of blue -->
<color name="holo_blue_bright">#ff00ddff</color>

You could try this :
