Question

我有像这样的字符串数组。

<resources>
    <string-array name="names">
        <item>foo/item>
        <item>bar</item>
        <item>moo</item>
    </string-array>
    <string-array name="majors">
        <item>E.P</item>
        <item>M.P</item>
        <item>E.P</item>
    </string-array>
    <integer-array name="years">
        <item>1968</item>
        <item>1993</item>
        <item>1995</item>
    </integer-array>
</resources>

RealmObject的Student类。

public class Student extends RealmObject {

    @PrimaryKey
    private int id;
    private String name;
    private String major;
    private Short year;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

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

    public String getMajor() {
        return major;
    }

    public void setMajor(String major) {
        this.major = major;
    }

    public Short getYear() {
        return year;
    }

    public void setYear(Short year) {
        this.year = year;
    }
}

我想循环遍历每个字符串数组，并将每个名称，专业和年份放入领域对象（学生）.realm.commitTransaction（）将数据插入到一个对象。我想将数据作为三个学生插入到领域数据库我怎么能这样做？

试试这段代码，

String[] names = getResources().getStringArray(R.array.names);
        String[] majors = getResources().getStringArray(R.array.majors);
        String[] years = getResources().getStringArray(R.array.years);
        realm.executeTransaction(new Realm.Transaction() {
            @Override
            public void execute(Realm realm) {
               for(int i=0; i<names.size; i++) {
                   String name = names[i];
                   String major = majors[i];
                   String year = years[i];
                   short yearValue = Short.valueOf(year);

                   Student student = new Student();
                   student.setId(i);
                   student.setName(name);
                   student.setYear(yearValue);

                   realm.insertOrUpdate(student);
             }
        });

如何循环遍历字符串数组并添加到领域数据库？
