Android使用SAX解析XML(2)

school类包含了一个major列表，可以增加该列表的元素，以及返回该列表，还实现了Parcelable.Creator接口。

package com.hzhi.my_sax;import java.util.ArrayList;import android.os.Parcel;
import android.os.Parcelable;public class school implements Parcelable{public static final String tag_name = "School";public String name;
public String code;
public ArrayList<major> majors;public static final Parcelable.Creator<school> CREATOR =
new Parcelable.Creator<school>(){@Override
public school createFromParcel(Parcel in) {
// TODO Auto-generated method stub
return new school(in);
}@Override
public school[] newArray(int size) {
// TODO Auto-generated method stub
return new school[size];
}};@Override
public int describeContents() {
// TODO Auto-generated method stub
return 0;
}@Override
public void writeToParcel(Parcel arg0, int arg1) {
// TODO Auto-generated method stub}// 实现Parcelable接口
public school(Parcel in){this.name = in.readString();
this.code = in.readString();}// 构造函数
public school(String name, String code){this.name = name;
this.code = code;
this.majors = new ArrayList<major>();}// 增加专业
public void add_major(major m){this.majors.add(m);}// 返回专业
public ArrayList<major> get_majors(){
return this.majors;
}// 重写toString
public String toString() {
// TODO Auto-generated method stub
return (getName());
}public String getName() {if(this.name == null) {
return ("(Default)");
}return (this.name);}}

major类包含了一个clas列表，可以增加该列表的元素，以及返回该列表，也实现了Parcelable.Creator接口。

package com.hzhi.my_sax;import java.util.ArrayList;
import android.os.Parcel;
import android.os.Parcelable;public class major implements Parcelable{public static final String tag_name = "Major";public String name;
public String code;
public ArrayList<clas> clases;public static final Parcelable.Creator<major> CREATOR =
new Parcelable.Creator<major>(){@Override
public major createFromParcel(Parcel in) {
// TODO Auto-generated method stub
return new major(in);
}@Override
public major[] newArray(int size) {
// TODO Auto-generated method stub
return new major[size];
}};@Override
public int describeContents() {
// TODO Auto-generated method stub
return 0;
}@Override
public void writeToParcel(Parcel dest, int flags) {// TODO Auto-generated method stub
dest.writeString(this.name);
dest.writeString(this.code);}// 实现Parcelable接口
public major (Parcel in){this.name = in.readString();
this.code = in.readString();}// 构造函数
public major(String name, String code){this.name = name;
this.code = code;
this.clases = new ArrayList<clas>();}public String getCode() {
return (this.code);
}public void add_clas(clas c) {
this.clases.add(c);
}public ArrayList<clas> get_clases() {
return this.clases;
}// 重写toString
public String toString() {
// TODO Auto-generated method stub
return (getName());
}public String getName() {if(this.name == null) {
return ("(Default)");
}return (this.name);}}

clas类就不用包含列表了，但还是需要实现Parcelable.Creator接口。

package com.hzhi.my_sax;import android.os.Parcel;
import android.os.Parcelable;public class clas implements Parcelable {public static final String tag_name = "Class";public String name;
public String code;public static final Parcelable.Creator<clas> CREATOR =
new Parcelable.Creator<clas>(){@Override
public clas createFromParcel(Parcel in) {
// TODO Auto-generated method stub
return new clas(in);
}@Override
public clas[] newArray(int size) {
// TODO Auto-generated method stub
return new clas[size];
}};@Override
public int describeContents() {
// TODO Auto-generated method stub
return 0;
}@Override
public void writeToParcel(Parcel dest, int flags) {// TODO Auto-generated method stub
dest.writeString(this.name);
dest.writeString(this.code);}public clas(Parcel in){this.name = in.readString();
this.code = in.readString();}public clas (final String name, final String code){this.name = name;
this.code = code;}// 重写toString
public String toString() {
// TODO Auto-generated method stub
return (getName());
}public String getName() {if(this.name == null) {
return ("(Default)");
}return (this.name);}}
