为什么我的自定义ListView没有显示所有的小部件?

我正在编写一个带有自定义Listview的约会应用程序。ListView由

• 视图,其颜色表示优先级
• 复选框,用于选择项目。
• DateText,显示约会的日期
• MonthText,显示约会的月份
• TimeText,显示约会的时间
• 标题,用于存储约会摘要

listView中的每一行都应该如下所示:

但只有两个小部件可见:DateText和MonthText。其余的则不然。为什么会这样?

我的 XML 和 getView() 方法如下:

    <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"

        android:layout_alignParentLeft="true" />

    <CheckBox

获取视图()

public View getView(int position, View convertView, ViewGroup parent) {

                    // List views that go off the screen are recycled.

                    View recycledView = convertView;

                    if (recycledView == null) {
                        /*
                         * If there is no view to recycle (e.g. when the listview is
                         * first created) we must inflate the view from the xml file
                         * using Layout Inflater.
                         */

                        LayoutInflater inflater = (LayoutInflater) context
                                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

                        recycledView = inflater.inflate(R.layout.row, null);
                    }

                    /*
                     * We now have a view to work with. We will now fill in the contents
                     * of this list view item.

                    Appointment current = items.get(position);
                    if (current != null) {

                        Log.e("crap",current.toString());

                        View priorityIndicator = (View) recycledView.findViewById(R.id.priorityView);
