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?
        }
    });
}
}

Solution

  • 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.
