尝试从SQLite数据库填充ListView

Question

I'm trying to populate a list view with data from my database:

protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_visualizar);
        EventoSQLHelper e = new EventoSQLHelper(this);
        e.Open();
        Cursor c = e.getRegistros();
        String resp = "";

        List<String> list = new ArrayList<String>();

        ListView eventos = (ListView) findViewById(R.id.list_eventos);
        TextView tx = new TextView(this);
        for (c.moveToFirst(); !c.isAfterLast(); c.moveToNext()) {
            resp = c.getString(c.getColumnIndex("id"))
                    + c.getString(c.getColumnIndex("descricao"))
                    + c.getString(c.getColumnIndex("dataEvento"));
            list.add(resp);
        }
        ArrayAdapter<String> adpt = new ArrayAdapter<String>(this,android.R.layout.activity_list_item,list);
        eventos.setAdapter(adpt);
        e.close();
    }

But it gave me an error:

I want to list the data and later i want to click on any item, and send a sms to a list of contacts. But i can't even list the data...what am i doing wrong?

java.lang.IllegalStateException: ArrayAdapter requires the resource ID to be a TextView

ArrayAdapter expects a resource that is just a TextView. android.R.layout.activity_list_item is a LinearLayout holding an ImageView and a TextView. Use android.R.layout.simple_list_item_1 instead.
