view story

http://stackoverflow.com – I am an Android newbie, and I have a problem regarding ListView. I have many elements inside one row of a ListView, and I want them to be clickable individually and show different activities. This is my ListView- <ListView android:id="@+id/mainContentList" android:layout_width="fill_parent" android:layout_height="wrap_content" android:cacheColorHint="#00000000" android:dividerHeight="15dp" android:divider="#00000000" android:scrollbarStyle="outsideInset" android:paddingRight="10dp" android:paddingLeft="10dp" /> This is the single row of the ListVie (HowTos)
