默认，AIDL支持对象作参数，但需要该对象实现Parcelable接口，且aidl文件应该是该类在同一包下，需要单独给该类定义一个aidl文件. 定义模型类: EnglishItem.java:
package com.pocketdigi.english.aidl;
import android.os.Parcel;
import android.os.Parcelable;
import com.j256.ormlite.field.DatabaseField;
import com.j256.ormlite.table.DatabaseTable;
import com.pocketdigi.english.utils.Constants;
import com.pocketdigi.english.utils.Des;
@DatabaseTable(tableName = "listenlist")
public class EnglishItem implements Parcelable {
/**
*
*/
private static final long serialVersionUID = -1756522544697525757L;
@DatabaseField(id = true)
private int id;
@DatabaseField
private String title;
@DatabaseField
private String category;
@DatabaseField
private String mp3url;
@DatabaseField
private String lrcurl;
@DatabaseField
private String txturl;
public static final Parcelable.Creator CREATOR = new Parcelable.Creator() {
public EnglishItem createFromParcel(Parcel in) {
return new EnglishItem(in);
}
public EnglishItem[] newArray(int size) {
return new EnglishItem[size];
}
};
private EnglishItem(Parcel in)
{
readFromParcel(in);
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getCategory() {
return category;
}
public void setCategory(String category) {
this.category = category;
}
public String getMp3url() {
return Des.decodeValue(Constants.DES_KEY, mp3url);
}
public void setMp3url(String mp3url) {
this.mp3url = mp3url;
}
public String getLrcurl() {
return Des.decodeValue(Constants.DES_KEY, lrcurl);
}
public void setLrcurl(String lrcurl) {
this.lrcurl = lrcurl;
}
public String getTxturl() {
return Des.decodeValue(Constants.DES_KEY, txturl);
}
public void setTxturl(String txturl) {
this.txturl = txturl;
}
@Override
public int describeContents() {
// TODO Auto-generated method stub
return 0;
}
@Override
public void writeToParcel(Parcel out, int flag) {
// TODO Auto-generated method stub
out.writeInt(id);
out.writeString(title);
out.writeString(category);
out.writeString(mp3url);
out.writeString(lrcurl);
out.writeString(txturl);
}
/**
* 读
* @param in
*/
public void readFromParcel(Parcel in)
{
id=in.readInt();
title=in.readString();
category=in.readString();
category=in.readString();
lrcurl=in.readString();
txturl=in.readString();
}
}
Parcelable.Creator不可少。 同包下定义一个EnglishItem.aidl：
package com.pocketdigi.english.aidl;
parcelable EnglishItem;
最后是调用接口aidl： PlayerAidl.aidl:
package com.pocketdigi.english.aidl;
import com.pocketdigi.english.aidl.EnglishItem;
interface PlayerAidl {
/**
*传入列表
**/
void putList(inout List item);
/**
*播放指定音频
**/
void play(int index);
void pause();
/**
*暂停后恢复播放
**/
void resume();
/**
*删除指定项
**/
void delete(int position);
/**
*停止服务
**/
void stopService();
}
