My solution like this. Defined a view extends ImageView called ToggleExpandableMenuButton,There is an interface in it. public interface ToggleListener { void toggle(); } Override the method performClick(){ if (listener != null) { listener.toggle(); } }

And set a ToggleListener on your ToggleExpandableMenuBotton in your adapter. If I don't talk it clear ,download the attachment and change the suffix to '.java' or leave ur email here.
