ExpandableListView top fading edge always visible

I have an ExpandableListView with the following set as the style

<style name="expendable_list_view">
    <item name="android:background">@color/background</item>
    <item name="android:cacheColorHint">@color/background</item>
</style>

Now, the bottom fading edge behaves normally, 开发者_运维技巧but the top one always fades to black. I have tried setting

android:fadingEdge="none"

and again, only the bottom fading edge is gone.

Any ideas?

Ok, the problem was somewhere else.

The ExpendableListView was loaded into the application using LocalActivityManager and it seems that all the Activities have some sort of transparent-to-black fade on the top. So I have simply changed the theme:

<style name="CustomActivityTheme" parent="@android:style/Theme.NoTitleBar">
    <item name="android:windowFrame">@null</item>
    <item name="android:windowContentOverlay">@null</item>
</style>

So, that solves the problem :) Thanks for all the help!

You need to set the cache color hint to #00000000
