(1)例如你有一个文件musicController.aidl,内容如下，其中Mp3InfoBean为你自己创建的类，这是要导入这个类的方法如下。

musicController.aidl

package com.lau.music.aidl;import com.lau.music.aidl.srvCallBack;import com.lau.music.aidl.Mp3InfoBean;interface musicController {    boolean playNext(in Mp3InfoBean mp3);    boolean playPre(in Mp3InfoBean mp3);    void pause();    boolean start(in Mp3InfoBean mp3);    void play();    double getMp3Length();    double getMp3CurrPos();    void setProgress(int prog);    boolean isPlaying();    void registCallBack(srvCallBack cb);    }

（2）第一步，首先创建一个文件Mp3InfoBean.aidl，代码如下

Mp3InfoBean.aidl

package com.lau.music.aidl;parcelable Mp3InfoBean;

同时需要把他们放在同一个包名下面，如下所示。

（3）同时，Mp3InfoBean.java需要实现Parcelable接口，这样就需要重写方法，同时需要定义成员变量CREATOR，如下所示，要注意函数writeToParcel中writeString的顺序得跟你读出来的顺序是一致的。

@Overridepublic int describeContents() {    return 0;}   @Overridepublic void writeToParcel(Parcel dest, int flags) {    dest.writeString(name);    dest.writeString(path);}

public static final Parcelable.Creator<Mp3InfoBean> CREATOR = new Parcelable.Creator<Mp3InfoBean>() {    @Override    public Mp3InfoBean createFromParcel(Parcel source) {        return new Mp3InfoBean(source);    }    @Override    public Mp3InfoBean[] newArray(int size) {        return new Mp3InfoBean[size];    }     };public Mp3InfoBean(Parcel source) {    name = source.readString();    path = source.readString();}

Mp3InfoBean.java

public class Mp3InfoBean implements Parcelable{    private String name;    private String path;    public static final Parcelable.Creator<Mp3InfoBean> CREATOR = new Parcelable.Creator<Mp3InfoBean>()    {        @Override        public Mp3InfoBean createFromParcel(Parcel source) {            return new Mp3InfoBean(source);        }        @Override        public Mp3InfoBean[] newArray(int size) {            return new Mp3InfoBean[size];        }            };        public Mp3InfoBean() {    }        public Mp3InfoBean(String n, String p) {        this.name = n;        this.path = p;    }        public Mp3InfoBean(Mp3InfoBean in) {        this.name = in.name;        this.path = in.path;    }    public String getName() {        return name;    }        public void setName(String name) {        this.name = name;    }        public String getPath() {        return path;    }        public void setPath(String path) {        this.path = path;    }    @Override    public int describeContents() {        return 0;    }        public Mp3InfoBean(Parcel source) {        name = source.readString();        path = source.readString();    }    @Override    public void writeToParcel(Parcel dest, int flags) {        dest.writeString(name);        dest.writeString(path);    }}

（4）如果在你自己创建的类里面包含着另一个自己创建的类的List，如下,其中LrcSentenceBean为自定义类，这个时候，要这样处理。

public class LrcBean implements Parcelable {        private String lrcName = null;    private String lrcPath = null;    private List<LrcSentenceBean> lrcContent = null;...}

    public LrcBean(Parcel source) {        lrcName = source.readString();        lrcPath = source.readString();        source.readList(lrcContent, null);    }        @Override    public int describeContents() {        return 0;    }    @Override    public void writeToParcel(Parcel dest, int flags) {        dest.writeString(lrcName);        dest.writeString(lrcPath);        dest.writeList(lrcContent);    }
