aidl 传递对象

1. 第一：实现Parcelable接口 
   
2. 第二：定义一个Parcelable.Creator类型的CREATOR对象 
   
3. 第三：要提供一个Booka.aidl文件，其中内容为parcelable Booka，定义了之后，在其他aidl文件中引用Booka时便不会提示出错了。 
4. Booka.java
5. public class Booka implements Parcelable {
   
   
   private String bookName;
   private int bookPrice;
   
   
   
   
   public String getBookName() {
   return bookName;
   }
   
   
   public void setBookName(String bookName) {
   this.bookName = bookName;
   }
   
   
   public int getBookPrice() {
   return bookPrice;
   }
   
   
   public void setBookPrice(int bookPrice) {
   this.bookPrice = bookPrice;
   }
   
   
   public int describeContents() {
   return 0;
   }
   
   
   public void writeToParcel(Parcel parcel, int flags) {
   parcel.writeString(bookName);
   parcel.writeInt(bookPrice);
   }
   
   
   public static final Parcelable.Creator<Booka> CREATOR = new Creator<Booka>() {
   public Booka createFromParcel(Parcel source) {
   Booka a=new Booka();
   a.setBookName(source.readString());
   a.setBookPrice(source.readInt());
   return a;
   }
   
   
   public Booka[] newArray(int size) {
   return new Booka[size];
   }
   };
   
   
   }
   
6. import 导入相应的包;
   
7. Booka.aidl     parcelable Booka;
8. Ibooka
9. interface Ibooka{
   Booka getBook();
   }
   
10. 服务端代码
11. public class RemoteService extends Service {
    
    
    private final static String TAG = "RemoteService";
    
    
    @Override
    public IBinder onBind(Intent intent) {
    Log.i(TAG, "执行了OnBind");
    return new MyBinder();
    }
    
    
    private class MyBinder extends aaaa.Stub {
    
    
    @Override
    public Booka getBook() throws RemoteException {
    Booka a = new Booka();
    a.setBookName("金瓶梅");
    a.setBookPrice(125);
    
    
    return a;
    }
    
    
    }
    }
    
12. 客户端代码
13. private class MyServiceConnection implements ServiceConnection {
    
    
    @Override
    public void onServiceConnected(ComponentName name, IBinder service) {
    // TODO Auto-generated method stub
    aaaa asInterface = aaaa.Stub.asInterface(service);
    if (asInterface == null) {
    return;
    }
    try {
14.                                 //获取另一个程序的Booka对象
    Booka allInfo = asInterface.getBook();
15. 
    } catch (RemoteException e) {
    e.printStackTrace();
    }
    }
    
    
    @Override
    public void onServiceDisconnected(ComponentName name) {
    // TODO Auto-generated method stub
    
    
    }
    
    
    }
    
    
    MyServiceConnection connection = new MyServiceConnection();
    
16. Intent intent = new Intent(“隐士意图的action”);
    bindService(intent, connection, Context.BIND_AUTO_CREATE);
    
17.
