XmlPullParser解析xml数据

解析assets目录下的persons.xml文件；

<?xml version="1.0" encoding="UTF-8"?>  
<persons>  
    <person id="1001">  
        <name> 路人甲</name>  
        <age>25</age>  
    </person>  
    <person id="1002">  
        <name>路人乙</name>  
        <age>26</age>  
    </person>  
</persons>

	private TextView textView;
