so im trying to set up a setOnClickListener for my ListView but its causing a crash in my program for some reason when i try.. im quite new to programming so when it comes to troubleshooting i cant really do anything sadly :( my code is below so any ideas on what could be wrong would be extremely helpful

public class HomePageActivity extends Activity {
    //ListView that holds the items
    ListView lstTest;

    //Array Adapter that holds the ArrayList and displays the items on the ListView
    AlertsAdapter arrayAdapter;

    //List that hosts the items
    ArrayList<Alerts> alrts = null;

    /** Called when the activity is first created. */
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.homepage);

        //Initialize the ListView
        lstTest = (ListView)findViewById(R.id.lstText);

        //Initialize the ArrayList
        alrts = new ArrayList<Alerts>();

        //Initialize the array adapter
        arrayAdapter = new AlertsAdapter(HomePageActivity.this, R.layout.listitems,alrts);

        //Set the above adapter as the adapter of choice for our list
        lstTest.setAdapter(arrayAdapter);

        lstTest.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                Intent intent = new Intent(
                HomePageActivity.this,
                PromotionActivity.class
                );
                startActivity(intent);
            }
        });

        //... ... ...

    }
}

i saw that it said i probably want setOnItemClickListener which is originally what i had it coded as but that it wouldnt work since eclipse told me my code was wrong with it

+1  A: 

You need to use setOnItemClickListener()

and then new android.widget.AdapterView.OnItemClickListener()

not new View.OnItemClickListener()
