Scrolling a ListView changes everything from White to Black [duplicate]

Answer 1

ListView lv = getListView();
setCacheColorHint(0);

Set the cache color hint to zero.

Answer 2

If your ListView is drawn atop a more complex background -- say, a bitmap or gradient -- then you may need to disable the scroll cache entirely. I ended up setting android:scrollingCache="false" on my ListView to resolve this issue.

Answer 3

Android attempts to improve the performance of ListView scrolling by caching layout information. If you have long scrolling lists of data you should also set the the android:cacheColorHint property on the ListView declaration in the Activity’s AXML definition (to the same color value as your custom row layout’s background). Failure to include this hint could result in a ‘flicker’ as the user scrolls through a list with custom row background colors. So give the same color to the listitem's background and android:cacheColorHint.you can refer below code.

In my Adapter layout I gave as

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/ADAPTER_CONTAINER_PRIMARY"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#FAFAEE"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
android:gravity="center">
     .....

And in the List view

<ListView
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:id="@+id/LIST_GRID_LIST_INSTANCES"
            android:focusableInTouchMode="true"     
            android:smoothScrollbar="true"
            android:divider="@drawable/Gray"
            android:dividerHeight="0.05dp"
            android:cacheColorHint="#FAFAEE"
            android:background="@drawable/round"/>

Answer 4

Solution is very simple, you also need to set the cache color hint to black in xml.

android:cacheColorHint="#000000"

Answer 5

The solution is very simple, you also need to set the cache color hint to white: setCacheColorHint(Color.WHITE). You don't need to change the list items' background color.
