For triggering a method on click of a button in fragment, there are number of ways to achieve this. Try this.

If (getActivity() instanceof MainActivity){
     //Getting instance of your activity
     MainActivity instance = ((MainActivity)getActivity());
     //Using the instance calling the method in your activity
     instance.methodName();
}

Use the above code in your fragment on button click.

Another way is using Interface, calling its abstract methods in fragment and overriding it MainActivity; on button click those methods will be called.

Or you can also try using RxEventBus. You can publish it in the fragment and listen in the MainActivity.

Hope this resolves your issue.
