Retrieve position of clicked ListViewItem

I have a listview with items in it. Depending on which ListViewItem has been clicked I'd like to open an Activity and pass data to it. But how do I get the position of which ListViewItem has been clicked?

This is my code

public class tutorialActivity extends Activity{

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.tutorial);
        registerClickCallBack();
        ListView listView = (ListView) findViewById(R.id.tutorialList);

        String tutorialTitle1 = getResources().getString(R.string.tutorial1_title);
        String tutorialTitle2 = getResources().getString(R.string.tutorial2_title);
        String tutorialTitle3 = getResources().getString(R.string.tutorial3_title);
        String tutorialTitle4 = getResources().getString(R.string.tutorial4_title);
        String tutorialTitle5 = getResources().getString(R.string.tutorial5_title);
        String tutorialTitle6 = getResources().getString(R.string.tutorial6_title);
        String tutorialTitle7 = getResources().getString(R.string.tutorial7_title);
        String tutorialTitle8 = getResources().getString(R.string.tutorial8_title);
        String tutorialTitle9 = getResources().getString(R.string.tutorial9_title);
        String tutorialTitle10 = getResources().getString(R.string.tutorial10_title);
        String tutorialTitle11 = getResources().getString(R.string.tutorial11_title);
        String tutorialTitle12 = getResources().getString(R.string.tutorial12_title);
        String tutorialTitle13 = getResources().getString(R.string.tutorial13_title);
        String tutorialTitle14 = getResources().getString(R.string.tutorial14_title);

        String[] values = new String[] { tutorialTitle1, tutorialTitle2, tutorialTitle3, tutorialTitle4, tutorialTitle5, tutorialTitle6, tutorialTitle7, tutorialTitle8, tutorialTitle9, tutorialTitle10, tutorialTitle11, tutorialTitle12, tutorialTitle13, tutorialTitle14};

        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, android.R.id.text1, values);
        listView.setAdapter(adapter);
    }

    private void registerClickCallBack() {
        ListView list = (ListView) findViewById(R.id.tutorialList);
        list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View viewClicked,int position, long id) {
            //How do I retrieve this position that has been clicked?
        }
    });
}
}

Use getCheckedItemPosition() to determine the position of the selected item, assuming you have choiceMode:single.

http://developer.android.com/reference/android/widget/AbsListView.html#getCheckedItemPosition()

To simply get the position of the item that has been clicked in the onClick method, well that is right there for you already.

private void registerClickCallBack() {
        ListView list = (ListView) findViewById(R.id.tutorialList);
        list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View viewClicked,int position, long id) {
            //How do I retrieve this position that has been clicked?
            int thePositionThatWasClicked = position;
        }
    });

Easy one. Reference here : http://developer.android.com/reference/android/widget/AdapterView.html#getSelectedItemPosition() 

getSelectedItemPosition()

Declare values outside of onCreate

String[] values;

then just assign a value to it:

values = new String[] { tutorialTitle1, ... };

and then in onItemClick get string using values[position];

And start activity depending on that string.

Use String selectedItem = (String) list.getSelectedItem(); to get selected String. Position of clicked item you have from method public void onItemClick(AdapterView parent, View viewClicked,int position, long id)

Not sure what you are asking for, in the callback method you have position.
