Android: ListView Flicker effect. Any hints on how to get rid of this?

For some reason, whenever I scroll through my list of items, the background inside my listview disappears and reappears giving rise to a "flicker" effect which I don't really want. I've tried the suggestion at: How to make a ListView transparent in Android? but it doesn't work for some reason. Any suggestions?

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/screenLayout"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/background"
    >
        <TextView
        开发者_如何学JAVA    android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:background="@color/title_background"
            android:text="@string/whatsnew_title"
            >
        </TextView>
        <ListView
            android:id="@android:id/list"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            >
        </ListView>     
</LinearLayout>

Did you include android:cacheColorHint="#00000000"? It's the most important part of the proposed fix. I've just tried your code (obviously not an exact reproduction, as you're using references to project-specific resources) with it, and it seems to work.

This post on the Android Developers blog should be of your interest.

This can also be achieved from Java (code) side: listView.setCacheColorHint(Color.TRANSPARENT);

Check your theme.xml for <item name="android:windowBackground">@null</item>. If you have it - remove it. I think one of the popular resources gives this line as example (that's how I got mine).
