Android : How to get values from the selected item in a list view?

This is my code so far. This is working but it only shows the very first value I have in the listView , not the selecting item by the user. Please halp me with this. This is really important.

        unitListView.setChoiceMode(AbsListView.CHOICE_MODE_SINGLE);

          unitListView.setOnItemClickListener(new   AdapterView.OnItemClickListener() {
              public void onItemClick(AdapterView<?> parent, View view,
                                int position, long id) {

                  // selected item
                 TextView t1 = (TextView) findViewById(R.id.lblLUnitName);

                 String name=t1.getText().toString();

          //    String a= (String) unitListView.getItemAtPosition(position);

                       // touchpressed=position;
                    Toast.makeText(getApplicationContext(), "Selected Item :" +name, Toast.LENGTH_SHORT).show();

        }
    });
