ExpandableListView's inside a ScrollView won't scroll

Question

So i got this really annoying issue. I have got ExpandableListView's inside a ScrollView inside a RelativeLayout and when the ExpandableListView's are open(Expand) it's like the ScrollView won't work and i can't scroll to get to my lower View's.

XML:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"

    android:layout_below="@id/your_name_edit_text_id"
    />
</RelativeLayout>
</ScrollView>
</RelativeLayout>

Also in this layout i got a warning on the opening ScrollView - This ScrollView layout or its RelativeLayout parent is useless

I can upload pictures if youd like. Please if anyone can help it will be very appreciated. Thanks.

因此，据我研究的问题（并且研究了很多），在ExpandableListView处于打开状态时，无法滚动View's 。
