Android开发 AIDL使用自定义对象作参数或返回值

http://www.pocketdigi.com/20121129/952.html

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:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122

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<EnglishItem> CREATOR = new Parcelable.Creator<EnglishItem>() { 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：

1 2	package com.pocketdigi.english.aidl; parcelable EnglishItem;

最后是调用接口aidl：
PlayerAidl.aidl:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

package com.pocketdigi.english.aidl;   import com.pocketdigi.english.aidl.EnglishItem;   interface PlayerAidl { /** *传入列表 **/ void putList(inout List<EnglishItem> 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(); }
