move from fragment to another activity in android code example

Example 1: go to activity android

//going to another activity while ending the 
//previous one so that users cannot go back
btListe = (ImageButton)findViewById(R.id.Button_Liste);
    btListe.setOnClickListener(new OnClickListener()
    {    public void onClick(View v)
        {
            intent = new Intent(main.this, ListViewImage.class);
            startActivity(intent);
            finish();
        }
    });

Example 2: change fragment in android studio

// put the following code in onClickListner
// public void onClickListner(View view){
Navigation.findNavController(view).navigate(R.id.action_fromFragment_toFragment);
// action_fromFragment_toFragment is the id of transformatino, look in fragment map.
// }
