Strange White color at top and bottom of layout

I am using a custom title bar and a LinearL开发者_如何学运维ayout inside a ScrollView below it. I see this strange white color while I scroll above or below. Images attached.

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" ...>

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"

HTH
