it give null pointer exception on line

layoutinflater inflater = layoutinflater.from(context);

services_layout xml layout is

 <linearlayout             android:layout_width="match_parent"             android:layout_height="wrap_content">              <textview                 android:id="@+id/txt_intra"                 android:layout_width="wrap_content"                 android:layout_height="match_parent"                 android:layout_marginright="10dp"                 android:textcolor="#383838"                 android:textsize="15sp" />          </linearlayout>           <linearlayout             android:id="@+id/main_layout"             android:layout_width="match_parent"             android:layout_height="wrap_content"             android:orientation="vertical">          </linearlayout> 

nested_list xml layout is
