Remove shadow from top and bottom of ListView in android?

I’m assuming you’re talking about the fading edges. To disable them:

android:fadingEdge="none"

or

listView.setVerticalFadingEdgeEnabled(false);

UPDATE

As Pim Reijersen pointed out in the comments, android:fadingEdge is deprecated and will be ignored as of API level 14. Please use:

android:fadingEdgeLength="0dp"
