So stellen Sie den ausgewählten Kontakt in der Listenansicht ein?

Question

hallo alle ich nahm Kontakt in einem Listview Hier setzen will, ist mein Code:

TextView contactsDisplay; 
    Button pickContacts,Btn_sms,Btn_call; 
    final int CONTACT_PICK_REQUEST = 1000; 
ListView lst; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
Btn_sms=(Button) findViewById(R.id.for_sms); 
Btn_call=(Button)findViewById(R.id.for_call); 
     contactsDisplay = (TextView) findViewById(R.id.txt_selected_contacts); 
     pickContacts = (Button) findViewById(R.id.btn_pick_contacts); 
lst =(ListView)findViewById(R.id.list); 
     pickContacts.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 

       Intent intentContactPick = new Intent(MainActivity.this,ContactsPickerActivity.class); 
       MainActivity.this.startActivityForResult(intentContactPick,CONTACT_PICK_REQUEST); 
      } 
     }); 
    } 

    @Override 
    public void onActivityResult(int requestCode,int resultCode,Intent data){ 
     super.onActivityResult(requestCode, resultCode, data); 

     if(requestCode == CONTACT_PICK_REQUEST && resultCode == RESULT_OK){ 

      ArrayList<Contact> selectedContacts = data.getParcelableArrayListExtra("SelectedContacts"); 

      String display=""; 
      for(int i=0;i<selectedContacts.size();i++){ 

       display += (i+1)+". "+selectedContacts.get(i).toString()+"\n"; 

      } 
      contactsDisplay.setText("Selected Contacts : \n\n"+display); 
     } 
    } 

Ich habe das mit einem TextView (ContactsDisplay), aber jetzt möchte ich mit Listview (lst) zu tun
