        android:layout_height="wrap_content"
    />

</LinearLayout>

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        // Creating an array adapter to host the list view items
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, countries);

        // Get the reference of listview from the main layout
        ListView listView = (ListView) findViewById(R.id.listview);
        listView.setAdapter(adapter);

        // This statement enables text filtering in the listview
