Question

I’ve followed this tutorial but when I try to run the application I get Unfortunately HelloListView has stopped
The IDE gives no warnings or errors.

My HelloViewListActivity.java looks like this:

public class HelloListViewActivity extends ListActivity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        String[] countries = getResources().getStringArray(R.array.countries_array);
        setListAdapter(new ArrayAdapter<String>(this, R.layout.list_item, countries));

        ListView lv = getListView();
        lv.setTextFilterEnabled(true);

        lv.setOnItemClickListener(new OnItemClickListener() {
            public void onItemClick(AdapterView<?> parent, View view,
                    int position, long id) {
                // When clicked, show a toast with the TextView text
                Toast.makeText(getApplicationContext(),
                        ((TextView) view).getText(), Toast.LENGTH_SHORT).show();
            }
        });
    }
}

My strings.xml and list_item.xml are both identical to the tutorial.

What is it that I am doing wrong?

Answer 1

You have to add setContentView(R.layout.yourlayout) after the super.onCreate(savedInstanceState);

the R.layout.yourlayout should look like this ( in folder res/layout ) :

<?xml version="1.0" encoding="utf-8"?>
<ListView 
  android:id="@android:id/list"
  android:layout_width="fill_parent"
  android:layout_height="wrap_content" />
