Activity传递一个或者多个对象

Activity传递一个或者多个对象

博客分类：
android_activity



Activity之间传递对象,或者通过Bundle传递对象的两种方式。

1:Serializable方式

传递一个对象

2:Parcelable方式

传递一个对象、传递多个对象(ArrayList<Object>)

方式一:Serializable

传递类:



Java代码


public class CustomeClass implements Serializable{

/**
*
*/
private static final long serialVersionUID = -7060210544600464481L;
private String name;
private String id;
private int age;
private String sex;

public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}

}

发送部分:



Java代码


CustomeClass cc = new CustomeClass();
cc.setAge(21);
cc.setId("123456");
cc.setName("mingkg21");
cc.setSex("男");

Intent intent = new Intent(this, PersonInfo.class);
intent.putExtra("PERSON_INFO", cc);
startActivity(intent);



接收部分:



Java代码


Intent intent = getIntent();
CustomeClass cc = CustomeClass)intent.getSerializableExtra("PERSON_INFO");
setTextView(R.id.id, cc.getId());
setTextView(R.id.name, cc.getName());
setTextView(R.id.sex, cc.getSex());
setTextView(R.id.age, String.valueOf(cc.getAge()));

方式二:Parcelable

传递类:



Java代码


public class CustomeParcelable implements Parcelable {

private String name;
private String id;
private int age;
private String sex;

public String getName() {
return name;
}

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

public String getId() {
return id;
}

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

public int getAge() {
return age;
}

public void setAge(int age) {
this.age = age;
}

public String getSex() {
return sex;
}

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

public static final Parcelable.Creator<CustomeParcelable> CREATOR = new Creator<CustomeParcelable>(){

public CustomeParcelable createFromParcel(Parcel source) {
// TODO Auto-generated method stub
CustomeParcelable cus = new CustomeParcelable();
cus.name = source.readString();
cus.id = source.readString();
cus.age = source.readInt();
cus.sex = source.readString();
return cus;
}

public CustomeParcelable[] newArray(int size) {
// TODO Auto-generated method stub
return new CustomeParcelable[size];
}

};

public int describeContents() {
// TODO Auto-generated method stub
return 0;
}

public void writeToParcel(Parcel dest, int flags) {
// TODO Auto-generated method stub
dest.writeString(name);
dest.writeString(id);
dest.writeInt(age);
dest.writeString(sex);
}

}

发送部分:



Java代码


CustomeParcelable cc = new CustomeParcelable();
cc.setAge(21);
cc.setId("123456");
cc.setName("mingkg21");
cc.setSex("男");

Intent intent = new Intent(this, PersonInfo.class);
intent.putExtra("PERSON_INFO", cc);
startActivity(intent);

接受部分:



Java代码


Intent intent = getIntent();
CustomeParcelable cc = intent.getParcelableExtra("PERSON_INFO");
setTextView(R.id.id, cc.getId());
setTextView(R.id.name, cc.getName());
setTextView(R.id.sex, cc.getSex());
setTextView(R.id.age, String.valueOf(cc.getAge()));

以上为Parcelable传递一个对象,若要实现传递多个对象,

传递部分:

Java代码


Bundle bundle = new Bundle();
bundle.putParcelableArrayList("mP3TagForNetDTOs",mP3TagForNetDTOs);
msg.setData(bundle);
endDocNotice.sendMessage(msg);

接受部分:

Java代码


Bundle bundle = msg.getData();
mP3TagForNetDTOs = bundle.getParcelableArrayList("mP3TagForNetDTOs");
