have you tried like below?

@Override
    protected void onCreate(Bundle savedInstanceState){
    setContentView(R.layout.activity_main);

    // find all view id here

    textview.setVisiblity(View.GONE);
    seekBar.setVisiblity(View.GONE);

    mySwitch.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            // do something, the isChecked will be
            // true if the switch is in the On position
            if(isChecked){
              textview.setVisiblity(View.VISIBLE);
              seekBar.setVisiblity(View.VISIBLE);
            }else{
              textview.setVisiblity(View.GONE);
              seekBar.setVisiblity(View.GONE);
            }
        }
    });
    }
