Android:自定义 ListView 中的 InflateException

在扩展自定义 ListView 行布局时，我遇到了这个异常。

E/AndroidRuntime(1241): android.view.InflateException: Binary XML file line #6: Error inflating class <unknown>

引用下面的代码...

CustomListViewAdapter.java

public View getView(final int position, View convertView, ViewGroup parent) {
    holder = null;
    ListViewRowData rowItems = (ListViewRowData) getItem(position);

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

    if (convertView == null) {
        convertView = inflater.inflate(R.layout.list_row, null); //<- throws inflate exception here

        holder = new ViewHolder();
        holder.dataFields = items.get(position);
        holder.mDeleteCB = (CheckBox) convertView
                .findViewById(R.id.DeleteCB);

        holder.mSeatName = (TextView) convertView.findViewById(R.id.SeatNo);
        holder.mAddDesc = (TextView) convertView
                .findViewById(R.id.CallDesc);
        holder.mCallIcon = (ImageView) convertView
                .findViewById(R.id.PaxCallIV);
        convertView.setTag(holder);
    } else {
        holder = (ViewHolder) convertView.getTag();
    }

    holder.mSeatName.setText(rowItems.getSeatName());
    holder.mAddDesc.setText(rowItems.getAddDesc());

    holder.mCallIcon.setImageDrawable(context.getResources().getDrawable(
            R.drawable.ic_launcher));

    return convertView;
}

list_row.xml

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

    <TextView
        android:id="@+id/SeatNo"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:padding="15dp"
        android:text="Seat"
        android:textSize="@android:attr/textAppearanceMedium"
        android:textStyle="bold" />

    <TextView
        android:id="@+id/CallDesc"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_below="@id/SeatNo"
        android:padding="15dp"
        android:text="Description :"
        android:textSize="@android:attr/textAppearanceMedium" />

    <ImageView
        android:id="@+id/PaxCallIV"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_alignParentTop="true"
        android:padding="10dp"
        android:src="@drawable/ic_launcher" />

    <CheckBox
        android:id="@+id/DeleteCB"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_below="@id/PaxCallIV"
        android:paddingRight="15dp" />

</RelativeLayout>

非常感谢任何形式的帮助或建议。谢谢!

文本外观引用，如 @android:attr/textAppearanceMedium，进入 android:textAppearance 属性，而不是 android:textSize。
