Repopulate your listview in onResume() of your activity,so that changes will appear in your listview after you will add new data.

public void onResume(){
        super.onResume();
        populateListview();
}

public void populateListview()
{
    //reset adapter
    listview.setAdapter(adapter);
}

What you need to do in this case is whenever you add the list item you need to set the Adapter again. or you can call the notifyDatasetchanged() method.

Try to do this.Hope this will solve your problem.

public void onPause(){
    super.onPause();
    Intent intent = getIntent();
    finish();
    startActivity(intent);        
}

Or

   //lv is your ListView
   lv.setAdapter(adapter);
   lv.invalidateViews();

after the contact list is updated.
