Android - Make a custom view selectable in a ListView -

so have listview, presenting custom views (each image + text). want views have different appearance when user selects them. (with overlay, try make work background)

if inflate row android.resource.layout.testlistitem, works, cell shows selected state when click.

however, try similar effect custom layout, , can't work. missing ?

i have view layout :

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@drawable/rowbackground">  ... (textview , image) 

and rowbackground.xml:

<?xml version="1.0" encoding="utf-8"?>  <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_selected="true" android:drawable="@drawable/bg_a" /> <item android:state_checked="true" android:drawable="@drawable/bg_b" /> <item android:state_pressed="true" android:drawable="@drawable/bg_c" /> <item android:state_selected="false" android:state_checked="false" android:state_pressed="false" android:drawable="@drawable/bg_d"/> </selector> 

but 2 work "default" , "pressed" states. not "selected" one. (i tried checked, see in samples)

how can make custom-layout view selectable ?

ok actually, handle "selected" state in listview, have use activated selector (android:state_activated), like:

<item android:state_activated="true" android:drawable="@drawable/ic_dep" /> 

of course doesn't seem documented anywhere. why, it's straightforward ? android
