Java 为什么XML属性不能在2.2.1和2.3中显示？

请注意，我对JAVA和Android非常陌生，谢谢

我正在读取一个Xml文件：

<question1 question="Que Grupo de los 80 Interpreta este Exito 1" answer="Esto esta la repuesta correcta 01" opt1="opcion1" opt2="opcion2" opt3="opcion2" youtubevideo="ID vide de youtube1" mp3="mp3 file1"/>

我不确定你是否还需要它，但我也遇到了同样的麻烦

解决方案：所有

getAttributeValue（）

内容必须在

START\u标记

case中，因为所有属性都存储在START标记中。它出现在android V2.3中
