Android pull解析xml

待解析的xml 文件:

<?xml version="1.0" encoding="utf-8"?>
<students>
    <student>
        <name sex="man">小明</name>
        <nickName>明明</nickName>
    </student>
    <student>
        <name sex="woman">小红</name>
        <nickName>红红</nickName>
    </student>
    <student>
        <name sex="man">小亮</name>
        <nickName>亮亮</nickName>
    </student>
</students>

student.java:

public class Student {

    private String name;
    private String sex;
    private String nickName;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getSex() {
        return sex;
    }

    public void setSex(String sex) {
        this.sex = sex;
    }

    public String getNickName() {
        return nickName;
    }

    public void setNickName(String nickName) {
        this.nickName = nickName;
    }
}

这里暂时将 student.xml 放在在了assets 文件夹中；
解析代码:

                try {
                    List<Student> students = pullXml("student.xml");
                    Log.d("TAG", "onClick: " + students.size());
                } catch (IOException e) {
                    e.printStackTrace();
                } catch (XmlPullParserException e) {
                    e.printStackTrace();
                }
//.............................................

   /**

    private List<Student> pullXml(String fileName) throws IOException, XmlPullParserException {
        List<Student> list = null;
        Student student = null;
        XmlPullParser parser = Xml.newPullParser();
        InputStream inputStream = getResources().getAssets().open(fileName);
        parser.setInput(inputStream, "utf-8");
        int type = parser.getEventType();
        while (type != XmlPullParser.END_DOCUMENT) {
            switch (type) {

                        student.setNickName(nickName);
                    }
                    break;
                case XmlPullParser.END_TAG:
                    if ("student".equalsIgnoreCase(parser.getName())) {
