AIDL是 Android Interface definition language的缩写，是android内部进程通信接口的描述语言，通过它我们可以进行进程间的通信。
AIDL使用步骤
使用AIDL一般是在两个应用的通信中使用。一个作为服务端提供接口，一个作为客户端调用接口。
使用步骤
1.在服务端定义自定义类型 注意需要实现Parcelable 接口：

| public class Car implements Parcelable {
public Car() {
}
private int prise;
public int getPrise() {
return prise;
}
public void setPrise(int prise) {
this.prise = prise;
}
protected Car(Parcel in) {
this.prise=in.readInt();//这两个方法一定要重写，不然传递的数据为空
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeInt(this.prise);//这两个方法一定要重写，不然传递的数据为空
}
@Override
public int describeContents() {
return 0;
}
public static final Creator<Car> CREATOR = new Creator<Car>() {
@Override
public Car createFromParcel(Parcel in) {
return new Car(in);
}
@Override
public Car[] newArray(int size) {
return new Car[size];
}
};
}
|
2.在服务端定义Car.aidl
1
2
| package com.orange.aidl;
parcelable Car;
|
创建时会提示接口名字要唯一，所以我先创建一个其他名字的，在修改名字为car
3.在服务端定义IMyAidlInterface

| import com.orange.aidl.Car;
interface IMyAidlInterface {
/**
* Demonstrates some basic types that you can use as parameters
* and return values in AIDL.
*/
int getCarPrise(in Car car);
void setCar(in Car car);
void basicTypes(int anInt, long aLong, boolean aBoolean, float aFloat,
double aDouble, String aString);
}
|
4.在服务端创建并定义Service，同时在AndroidManifest中定义Service
1
2
| android:name=".MyService"
android:exported="true"></service>

| public class MyService extends Service {
public MyService() {
}
@Override
public IBinder onBind(Intent intent) {
return iBinder;
}
Car carl;
private IBinder iBinder= new IMyAidlInterface.Stub()
{
@Override
public int getCarPrise(Car car) throws RemoteException {
if(carl!=null){
return carl.getPrise();
}else{
return 0;
}
}
@Override
public void setCar(Car car) throws RemoteException {
carl=car;
}
@Override
public void basicTypes(int anInt, long aLong, boolean aBoolean, float aFloat, double aDouble, String aString) throws RemoteException {
}
};
}
|
5.在客户端中重复前三步，其中名字都要一样
6.在客户端中绑定服务端的服务
1

| private void bindService(){
Intent intent=new Intent();
intent.setComponent(new ComponentName("com.orange.aidl","com.orange.aidl.MyService"));
bindService(intent,connection, Context.BIND_AUTO_CREATE);
}
|
7.在绑定服务后调用服务端的接口

| private ServiceConnection connection=new ServiceConnection() {
@Override
public void onServiceConnected(ComponentName name, IBinder service) {
TextView textView= (TextView) findViewById(R.id.tv);
iMyAidlInterface=IMyAidlInterface.Stub.asInterface(service);
Car car=new Car();
car.setPrise(1245633);
try {
iMyAidlInterface.setCar(car);
int prise= iMyAidlInterface.getCarPrise(car);
textView.setText(prise+"");
} catch (RemoteException e) {
e.printStackTrace();
}
}
@Override
public void onServiceDisconnected(ComponentName name) {
iMyAidlInterface = null;
}
};
