I have ExpandableListView with one group and one child.
When I expand group the child looks as I want. See:
good child

But when I tap on child and move my finger to up of the screen (it is no matter how far – 10 px or 50 px) and remove my finger I see this white backgroud:
bad child

How can I avoid this behavior?

EDITED 1:
I tried one more time and discovered that background changed even if I still pressing on screen. It happens where my finger is above the group view.

EDITED 2: 

<ExpandableListView
        android:id="@+id/list_filters"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:groupIndicator="@null" 
        android:divider="@null"/>

    That would appear to be the cache color hint… If you set it to transparent I believe your issue will be solved.

    You can do that in code with yourlistView.setCacheColorHint(0) or in the XML with android:cacheColorHint="#00000000".
