I have an activity that contains a fragment and a button outside of that fragment, I need to create an event that, by clicking on the button, replaces this fragment with another one. Here is a piece of code for you to see, the fragment " Fragment_Temas " gives me an error.

    two.setOnClickListener( new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            FragmentManager fragment_manager = getFragmentManager();
            FragmentTransaction transaction = fragment_manager.beginTransaction();
            transaction.replace( R.id.layout_fragment, Fragment_Temas);
            transaction.commit();
        }
    } );

You must instantiate the fragment to be able to replace the other fragment.

Try this:

two.setOnClickListener( new View.OnClickListener() {
   @Override
   public void onClick(View v) {

      Fragment_Temas fragmentTemas = new Fragment_Temas();

      FragmentManager fragment_manager = getFragmentManager();
      FragmentTransaction transaction = fragment_manager.beginTransaction();
      transaction.replace( R.id.layout_fragment, fragmentTemas);
      transaction.commit();
   }
});
