自定义ArrayAdapter中的不可达语句

public class CustomAdapter extends ArrayAdapter<String> {
    private Context mContext;
    private List<String> mData;

    public CustomAdapter(Context context, List<String> data) {
        super(context, 0, data);
        mContext = context;
        mData = data;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        if (convertView == null) {
            convertView = LayoutInflater.from(mContext).inflate(R.layout.list_item, parent, false);
        }

        // 设置列表项的文本
        TextView textView = convertView.findViewById(R.id.text_view);
        textView.setText(mData.get(position));

        // 不可达语句
        if (position == 0) {
            // 这段代码永远不会被执行到
            // ...
        }

        return convertView;
    }
}
