Strange White color at top and bottom of layout

Question

I am using a custom title bar and a LinearLayout inside a ScrollView below it. I see this strange white color while I scroll above or below. Images attached. Normal view

Strange White color as soon as white background scrolls towards the custom title bar. Image below.

How do I get rid of this white color, it also shows at the bottom of the layout. FYI, I am using Theme.Light.

Update: I get the same effect even at the bottom of the layout and it is more pronounced when the color in the foreground is white.

I had this same problem and it was driving me nuts. It's because the theme has a "dropshadow" by default, create a style and set it as the theme:

Style:

  <style name="ThemeNoDropshadow" parent="@android:style/Theme.Light">
    <item name="android:windowContentOverlay">@null</item>
  </style>

App manifest:

  <application android:theme="@style/ThemeNoDropshadow" ...>

Hmmm I guess I didn't get your problem then. – dmon May 20 '11 at 16:41
Somehow it does not fix it. No idea what could be wrong and this is driving me nuts too :) – PravinCG May 20 '11 at 16:53
Oh I see what it is now, isn't that just the scroll indicator? – dmon May 20 '11 at 19:18
Any idea how to remove the scroll indicator? – PravinCG May 21 '11 at 16:27
I wouldn't, given that's actually serving a purpose (in general), in action, the user should be used to seeing it. – dmon May 22 '11 at 02:41
not a super purpose; the scrollbar which pops up is a better indication of scrolling :) – ataulm May 23 '11 at 09:42
Well, in newer versions, once the scrollbar disappears you can "tell" at a glance if there are more items above or below, or I guess that was their intention. – dmon May 23 '11 at 14:27

I think I found the actual solution while looking into something else (serendipity!). Anyway, add this property in your view layout definition:

android:fadingEdge="none"

It's the cacheColorHint, assign it transparent if you want to get rid of it, as a property of the ListView.

Annoyed me too, and I never have it.

android:cacheColorHint="#0000"

The answer is correct for listView though what I am using is not a listview. It is a layout under scrollview and scrollview does not have this property. – PravinCG May 24 '11 at 15:14
