I have a ListView backed by customized ArrayAdapter where each item
has 2 LinearLayouts - one I call head, and the other one - body. The
body is hidden (gone) until user clicks on the row at which time it
slides out. The second click (on the head) will hide the body. However
if user clicks on the body it brings another activity. All of this
works just fine, here comes the problem:
When user presses on body I want a visual indication of the action
just the same way as regular list item will flicker an orange
background when pressed. I'm not getting this by default since (my
theory) the onPress event is intercepted by body's view and not
processed by the list item.
The first thing I tried was to execute body.setBackground('#ff00ff')
(never mind the color) in onPress event. That didn't work since (I
suspect) there's no repainting after the call. Then I dig a little bit
more and decided to use <selector/>-based background. I defined
body_background.xml in drawable folder and assigned that to the body's
background property.
There I noticed that background will only change if the even is
processed by the list. For example if I set <item
android:state_selected="true" android:drawable="@drawable/selected"/>
then when I press on the head - the background of both elements (head
and body) will change, however when I press on body - nothing.
So to summarize my question - how do I change background of the child
element in the list item if I assign custom onClick handler to it? Any
hints will be greatly appreciated
