我可以不使用xml文件在列表视图中添加一个视图吗？

public class CustomAdapter extends BaseAdapter {
    private List<String> data;
    private Context context;

    public CustomAdapter(List<String> data, Context context) {
        this.data = data;
        this.context = context;
    }

    @Override
    public int getCount() {
        return data.size();
    }

    @Override
    public Object getItem(int position) {
        return data.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // 创建或复用视图
        if (convertView == null) {
            convertView = new TextView(context);
        }

        // 设置视图内容
        String item = (String) getItem(position);
        ((TextView) convertView).setText(item);

        return convertView;
    }
}

// 在Activity或Fragment中使用Adapter
public class MainActivity extends AppCompatActivity {
    private ListView listView;
    private CustomAdapter adapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        listView = findViewById(R.id.listView);

        // 准备数据
        List<String> data = new ArrayList<>();
        data.add("Item 1");
        data.add("Item 2");
        data.add("Item 3");

        // 创建适配器并设置给列表视图
        adapter = new CustomAdapter(data, this);
        listView.setAdapter(adapter);
    }
}
