ListView in tabhost layout isn't rendering correctly

Question

I'm developing an application for Android 2.3.3 later. In an Activity I use a tabhost the first tab has a pager for photos, the second a list, The whole layout has a background image. When I test my app in my virtual Machine API lvl 18 there is no problem, when I test it in my device Android 2.3.6, I have a problem. When I scroll the list, its background becomes white and when I stop interacting with it, its background is returned to be the background of the layout.Is this a problem due to Android version? can I do something to fix it? this is the layout file just in case you se something I miss.

<?xml version="1.0" encoding="utf-8"?><TabHost xmlns:android="http://schemas.android.com/apk/res/android"
