expandablelistview - HorizontalScrollView in ExpandableList Android -

am trying implement horizontalscrollview in expandablelist group. group not expanding while clicking. when remove horizontalscrollview works normally.

<?xml version="1.0" encoding="utf-8"?> <relativelayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:background="@drawable/boilerbg" android:layout_marginright="15dip" android:layout_marginleft="15dip" android:gravity="center_vertical" >  <imageview     android:id="@+id/tag_img"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:layout_alignparentright="true"     android:layout_alignparenttop="true"     android:layout_marginright="5dip"     android:src="@drawable/group_down" />  <horizontalscrollview     android:id="@+id/horizontalscrollview1"     android:layout_width="150dip"     android:layout_height="20dip"     android:layout_alignparentleft="true"     android:layout_centervertical="true"     android:cachecolorhint="#00000000"     android:layout_marginleft="15dip"     android:isscrollcontainer="false"     android:descendantfocusability="blocksdescendants"     android:clickable="true"     android:scrollbars="none" >  <textview     android:id="@+id/group_title"     android:layout_width="wrap_content"     android:layout_height="wrap_content"            android:text=""     android:textcolor="#727272"     android:textsize="14dip"     android:textstyle="bold" />  </horizontalscrollview> 

a scrollview can contain 1 object.

replace textview linearlayout (or layout prefer) , let hold textviews.
