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:
123456789101112131415161718192021222324252627282930313233343536373839404142434445464748495051525354555657585960616263646566676869707172737475767778798081828384858687888990919293949596979899100101102103104105106107108109110111112113114115116117118119120121122 | 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：
12 | package com.pocketdigi.english.aidl;parcelable EnglishItem; |
最后是调用接口aidl：
PlayerAidl.aidl:
123456789101112131415161718192021222324252627 | 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();} |
