Question

I’m trying to make an app which displays a listview, and when you click on a specific item in that list, it will display a toast with specific information.

So far example, I got this code from this site:

public class MyListActivity extends ListActivity {
public void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    String[] values = new String[] { "Android", "iPhone", "WindowsMobile",
            "Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X",
            "Linux", "OS/2" };
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
            android.R.layout.simple_list_item_1, values);
    setListAdapter(adapter);
}

@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
    String item = (String) getListAdapter().getItem(position);
    Toast.makeText(this, item + " selected", Toast.LENGTH_LONG);
}

So how would I modify the code, for example, to display a toast containing information about Android when one clicks “android” in the list? And of course, then a different toast containing different info will be displayed when one clicks on “iPhone” etc.

Thanks for any help you can give 🙂

Answer 1

make String[] values a class variable .

toast.show() is missing .

Toast.makeText(this, values[position] + " selected", Toast.LENGTH_LONG).show();

Updating

public class MyListActivity extends ListActivity 
{

    private String[] values ;

    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
         values = new String[] { "Android", "iPhone", "WindowsMobile",
                "Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X",
                "Linux", "OS/2" };
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_1, values);
        setListAdapter(adapter);
    }

    @Override
    protected void onListItemClick(ListView l, View v, int position, long id) {

        Toast.makeText(this, values[position]+ " selected", Toast.LENGTH_LONG);
    }
