Answer 1

hinzufügen Pause unter startActivity (i);

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
     @Override 
     public void onItemClick(AdapterView<?> parent, View view, int position, long id) { 
      switch (position){ 
       case 0: 
        Intent i = new Intent(getActivity(),dia1.class); 
        startActivity(i); 
       break; 

      } 
     } 
    });
