android - Onclick() in a Parent Fragment does not get called -

i have fragmentpager implementing 3 tabs. inside 1 of tabs need this: if user clicks on button want load fragment inside tab , if user clicks on button b want load fragment b in page.

but i'm stuck @ first phase. when click on button onclick method not called. following steps given in slidenerd.com video #10 fragments.

i have implemented onclickslistener , added onclick method example. toast message not fire.

below code mainactivity , parent fragment (the mentioned tab) , xml.

thanks in advance.

mainactivity.java

i think didn't register fragment view in parent view. please try code. think work!

@override public view oncreateview( layoutinflater inflater, viewgroup container, bundle savedinstancestate) {     //view rootview = inflater.inflate(r.layout.quick_create_property_listing, container,false);     view rootview = inflater.inflate(activity, r.layout.quick_create_property_listing, this);     return rootview; }
