[Android] AIDL示例

1. 定义实体

package ai.serv;

import android.os.Parcel;
import android.os.Parcelable;

public class Person implements Parcelable {
    private String name;
    private int age;
    private String telNumber;
    
    
    @Override
    public int describeContents() {
        return 0;
    }

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeString(name);
        dest.writeString(telNumber);
        dest.writeInt(age);
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String getTelNumber() {
        return telNumber;
    }

    public void setTelNumber(String telNumber) {
        this.telNumber = telNumber;
    }

    public static final Parcelable.Creator<Person> CREATOR = new Parcelable.Creator<Person>() {

        @Override
        public Person createFromParcel(Parcel source) {
            return new Person();
        }

        @Override
        public Person[] newArray(int size) {
            return new Person[size];
        }
    };
}

package ai.serv;

parcelable Person;

2. 定义接口

package ai.serv; 

import ai.serv.Person; 

interface IAIDLServer { 
        void savePersonInfo(in Person person); 
        List<Person> getAllPerson(); 
}

3. Service端接口实现

    ArrayList<Person> persons = new ArrayList<Person>(10);
    
    final IAIDLServer.Stub mBinder = new IAIDLServer.Stub() {
        
        @Override
        public void savePersonInfo(Person person) throws RemoteException {
            if (person != null) {
                persons.add(person);
            }
        }
        
        @Override
        public List<Person> getAllPerson() throws RemoteException {
            return persons;
        }
    };
    
    @Override
    public IBinder onBind(Intent intent) {
        return mBinder;
    }

4. 客户端实现

IAIDLServer mServer = null;
    
    ServiceConnection connection = new ServiceConnection() {
        
        @Override
        public void onServiceDisconnected(ComponentName name) {
            if (mServer != null) {
                mServer = null;
            }
            Toast.makeText(AIDLClentA.this, "Disconnected", Toast.LENGTH_SHORT).show();
        }
        
        @Override
        public void onServiceConnected(ComponentName name, IBinder service) {
            mServer = IAIDLServer.Stub.asInterface(service);
            Toast.makeText(AIDLClentA.this, "Connected", Toast.LENGTH_SHORT).show();
        }
    };

5. 客户端连接、断开

bindService(new Intent(IAIDLServer.class.getName()), connection, BIND_AUTO_CREATE);

unbindService(connection);
