Listselector For Group Header And Child Layout In Expandablelistview Not Working Android

I am using ExpandableListview that displays data dynamically from server. I used selector for Group Header and Child Layout, but I can't notice any selector that reflects. Pls help

Solution 1:

Your selector is missing the default selector put the default color like below, instead of adding the selector in the ExpandableList try adding it as a background for the rootView of your Parent and Child layouts.

<selector xmlns:android="http://schemas.android.com/apk/res/android"
   android:exitFadeDuration="@android:integer/config_mediumAnimTime">

   <item android:drawable="@android:color/holo_blue_bright" android:state_pressed="true"/>
   <item android:drawable="@android:color/holo_blue_light" android:state_selected="true"/>
   <item android:drawable="@android:color/holo_blue_dark" android:state_activated="true"/>
   <item android:drawable="@android:color/transparent" />
  </selector>
