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.
