Answer 1

 Button mButNext = (Button) findViewById(R.id.btn_next);
        mButNext.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                PropertyListFragment plf = PropertyListFragment.newInstance("param1", "param2"); 
getSupportFragmentManager().beginTransaction().replace(R.id.sample_content_fragment, plf, "tag").commit();
            }
        });

You use an Intent to open another Activity.

If your goal is to show the Fragment in it's own Activity then create an intent to start the new Activity, and have the target Activity load your Fragment in onCreate. See Adding a Fragment to an Activity

If your goal is to show the Fragment in the same Activity then read slightly further down in the previous link about programmatically add the fragment to an existing ViewGroup
