Solution

You can define custom clickListener class and create it's instance in fragment and set listener instance there. Now you can write code in that class. Hope it will help you.

public class MyCustomListener implements OnClickListener{

     @override
     public void onClick(View v){

     // you stuff
     }  
}

then in your fragment call this

MyCustomListener listener=new MyCustomListener();
btn.setOnClickListener(listener);
