在开发中不少要用到Activity直接传输对象，下面我们来看看，其实跟java里面差不多
自定义对象的传递：通过intent传递自定义对象的方法有两个
第一是实现Serialization接口；
第二是实现Parcelable接口；
下面来看个例子：
package com.example.bean;
import java.io.Serializable;
public class Bed implements Serializable {
private String name;
private int number;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getNumber() {
return number;
}
public void setNumber(int number) {
this.number = number;
}
@Override
public String toString() {
return "Name：" + getName() + "，Number：" + getNumber();
}
}
package com.example.bean; import android.os.Parcel;
import android.os.Parcelable; public class Patient implements Parcelable { private String name;
private int number; public String getName() {
return name;
} public void setName(String name) {
this.name = name;
} public int getNumber() {
return number;
} public void setNumber(int number) {
this.number = number;
} public static final Parcelable.Creator<Patient> CREATOR = new Parcelable.Creator<Patient>() {
public Patient createFromParcel(Parcel p) {
Patient patient = new Patient();
patient.name = p.readString();
patient.number = p.readInt();
return patient;
} public Patient[] newArray(int size) {
return new Patient[size];
}
}; @Override
public int describeContents() {
return ;
} /**
*
*@desc 注：这里的write方法和createFromParcel里的一一对应，不然createFromParcel都是p.readString()，你怎么知道是哪一个
*
*/
@Override
public void writeToParcel(Parcel p, int flags) {
p.writeString(name);
p.writeInt(number);
} @Override
public String toString() {
return "Name：" + getName() + "，Number：" + getNumber();
} }
TestActivity.java：
StringBuilder sb = new StringBuilder();
sb.append("Serializable Bed对象\n");
Bed bed = (Bed) getIntent().getExtras().get("bed");
sb.append(bed.toString());
sb.append("\n\nList<Serializable Bed>集合\n");
List<Bed> listBed = (List<Bed>) getIntent()
.getSerializableExtra("beds");
for (int i = ; i < listBed.size(); i++) {
sb.append(listBed.get(i).toString() + "；");
}
sb.append("\n\nParcelable Patient对象\n");
Patient patient = getIntent().getParcelableExtra("patient1");
sb.append(patient.toString());
sb.append("\n\nParcelable Patient byte[]\n");
byte[] data = getIntent().getByteArrayExtra("patient2");
if (data != null) {
Parcel in = Parcel.obtain();
in.unmarshall(data, , data.length);
in.setDataPosition();
patient = Patient.CREATOR.createFromParcel(in);
}
sb.append(patient.toString());
sb.append("\n\nString数组\n");
String[] str = getIntent().getStringArrayExtra("patients");
for (int i = ; i < str.length; i++) {
sb.append(str[i]);
}
TextView tv = (TextView) findViewById(R.id.tv);
tv.setText(sb);
