Android SAX 解析 XML

下面是效果图，代码中有详细解释，

 res/raw/person.xml

<?xml version="1.0" encoding="UTF-8"?>  <persons>      <person id="001">          <name>张三</name>          <age>22</age>      </person>            <person id="002">          <name>李四</name>          <age>23</age>      </person>            <person id="003">          <name>王五</name>          <age>24</age>      </person>  </persons>
