Question

I have no idea why, but randomly the “arrow” doesn’t show up on my list renderers/items (see pic). Does anybody know why? I’m not touching it with code. hierarchyviewer suggests the height is 1 when this happens. However even explicitly setting the height to 20dp it still happens. This also happens when I change the orientation of the phone. Disabling “convertView” and always creating a new one does not help. Any ideas?

Using a transparent color of 00000000 breaks imageviews from rendering in a listview. Changing it to 00FFFFFF fixes it!

Colors:

<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="themeColor">#FF8312</color>
<color name="primary_background">#C9C7C1</color>

<color name="primary_text_light">#FFFFFF</color>
<color name="primary_text_dark">#4F4F4C</color>



<color name="white">#FFFFFF</color>
<color name="transparent">#00FFFFFF</color>
<!--     <color name="transparent">#00000000</color> -->

</resources>

Styles:

<style name="AlarmList" parent="@android:style/Widget.ListView">
<!--        <item name="android:listSelector">@drawable/list_selector_background</item> -->
    <item name="android:divider">@color/transparent</item>
    <item name="android:dividerHeight">10dp</item>
    <item name="android:cacheColorHint">@color/primary_background</item>
    <item name="android:background">@color/transparent</item>
</style>
