Scrolling on ListView makes background black

To avoid this problem, set "android:cacheColorHint="@android:color/transparent" on your ListView. E.g.:

<ListView android:id="@+id/main_list_view"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:cacheColorHint="@android:color/transparent"
    />
