1.定义数据传输对象
Person.aidl文件：
Person.java文件中：
（1）实现parcelable接口
（2）提供一个名为CREATOR的static final属性
package com.liujun.aidl;
import android.os.Parcel;
import android.os.Parcelable;
public class Person implements Parcelable{
private String name;
private int sex;
public Person(){
}
public Person(Parcel source){
readFromParcel(source);
}
//必须提供一个名为CREATOR的static final属性 该属性需要实现android.os.Parcelable.Creator<T>接口
public static final Parcelable.Creator<Person> CREATOR =new Parcelable.Creator<Person>() {
@Override
public Person createFromParcel(Parcel source) {
return new Person(source);
}
@Override
public Person[] newArray(int size) {
return new Person[size];
}
};
@Override
public int describeContents() {
return 0;
}
//注意读取变量和写入变量的顺序应该一致 不然得不到正确的结果
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(name);
dest.writeInt(sex);
}
//注意读取变量和写入变量的顺序应该一致 不然得不到正确的结果
public void readFromParcel(Parcel source) {
name = source.readString();
sex = source.readInt();
}
//////////////////////////////////////////////////////////////////
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getSex() {
return sex;
}
public void setSex(int sex) {
this.sex = sex;
}
}
2.定义远程服务接口和服务组件
IGreetService.aidl文件：
package com.liujun.aidl;
import com.liujun.aidl.Person;
interface IGreetService{
String greet(in Person person);
}
AIDLService.java文件：
package com.liujun.service;
import com.liujun.aidl.IGreetService;
import com.liujun.aidl.Person;
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.os.RemoteException;
import android.util.Log;
public class AIDLService extends Service {
private static final String TAG = "liujun";
@Override
public void onCreate() {
Log.i(TAG, "onCreate() called");
super.onCreate();
}
@Override
public IBinder onBind(Intent arg0) {
Log.i(TAG, "onBind() called");
return stub;
}
//服务接口实例对象
IGreetService.Stub stub=new IGreetService.Stub() {
@Override
public String greet(Person person) throws RemoteException {
Log.i(TAG, "greet(Person person) called");
return ServiceMethod(person);
}
};
@Override
public boolean onUnbind(Intent intent) {
Log.i(TAG, "onUnbind() called");
return true;
}
@Override
public void onDestroy() {
super.onDestroy();
Log.i(TAG, "onDestroy() called");
}
/////////////////-----------------------------------
/**
* 服务组件方法
* @param person
* @return
*/
public String ServiceMethod(Person person){
String greeting = "hello, " + person.getName();
switch (person.getSex()) {
case 0:
greeting = greeting + ", you‘re handsome."; 工程代码
break;
case 1:
greeting = greeting + ", you‘re beautiful.";
break;
}
return greeting;
}
}
注册服务：
<!-- 配置服务组件 -->
<service android:name="com.liujun.service.AIDLService">
<intent-filter>
<action android:name="android.intent.action.AIDLService" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</service>
3.客户端程序复制服务端程序数据传输对象和接口文件
4.绑定远程服务，调用远程服务方法，传输复杂对象
package com.liujun.parcelableclient;
import android.app.Activity;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.content.ServiceConnection;
import android.os.Bundle;
import android.os.IBinder;
import android.os.RemoteException;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;
import com.example.parcelableclient.R;
import com.liujun.aidl.IGreetService;
import com.liujun.aidl.Person;
public class MainActivity extends Activity {
//控件
private Button bindBtn;
private Button greetBtn;
private Button unbindBtn;
private boolean mBound=false;//是否绑定远程服务
//远程服务接口对象
private IGreetService iService;
//获取远程服务接口对象
private ServiceConnection conn=new ServiceConnection() {
@Override
public void onServiceConnected(ComponentName name, IBinder service) {
iService=IGreetService.Stub.asInterface(service);
mBound=true;
}
@Override
public void onServiceDisconnected(ComponentName name) {
mBound=false;
iService=null;
}
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
bindBtn=(Button) this.findViewById(R.id.bindBtn);
greetBtn=(Button) this.findViewById(R.id.greetBtn);
unbindBtn=(Button) this.findViewById(R.id.unbandBtn);
//注册点击监听器
MyListener listener=new MyListener();
bindBtn.setOnClickListener(listener);
greetBtn.setOnClickListener(listener);
unbindBtn.setOnClickListener(listener);
}
/**
* 事件处理器
* @author asus
*
*/
private class MyListener implements OnClickListener{
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.bindBtn:
//绑定远程服务
Intent intent = new Intent("android.intent.action.AIDLService");
bindService(intent, conn, Context.BIND_AUTO_CREATE);
//设置按钮状态
bindBtn.setEnabled(false);
greetBtn.setEnabled(true);
unbindBtn.setEnabled(true);
break;
case R.id.greetBtn:
try {
Person person = new Person();
person.setName("liujun");
person.setSex(0);
String retVal = iService.greet(person);
Toast.makeText(MainActivity.this, retVal, Toast.LENGTH_SHORT).show();
} catch (RemoteException e) {
Toast.makeText(MainActivity.this, "error", Toast.LENGTH_SHORT).show();
}
break;
case R.id.unbandBtn:
unbindService(conn);
bindBtn.setEnabled(true);
greetBtn.setEnabled(false);
unbindBtn.setEnabled(false);
break;
}
}
}
@Override
protected void onDestroy() {
super.onDestroy();
if (mBound) {
unbindService(conn);
iService=null;
}
}
