java - 尝试从 sqlite 数据库填充 listview

Question

我正在尝试使用数据库中的数据填充 ListView :

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();
    }

但它给了我一个错误:

我想列出数据，然后我想单击任何项​​目，并向联系人列表发送短信。但我什至无法列出数据...我做错了什么？

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

ArrayAdapter 需要一个只是 TextView 的资源。 android.R.layout.activity_list_item 是一个包含 ImageView 和 TextView 的 LinearLayout。请改用 android.R.layout.simple_list_item_1。
