1.新建IMyAidlInterface.aidl、Person.aidl文件
// IMyAidlInterface.aidl
package demo.com.aidldemo;
import demo.com.aidldemo.Person;
interface IMyAidlInterface {
/**
* Demonstrates some basic types that you can use as parameters
* and return values in AIDL.
*/
String getString(String string);
List<Person> getPersonList();
}
// Person.aidl
package demo.com.aidldemo;
parcelable Person;
2.服务端 MyService.java
package demo.com.aidldemo;
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.os.RemoteException;
import android.os.SystemClock;
import java.util.ArrayList;
import java.util.List;
public class MyService extends Service {
public MyService() {
}
@Override
public IBinder onBind(Intent intent) {
return mBinder;
}
IMyAidlInterface.Stub mBinder;
{
mBinder = new IMyAidlInterface.Stub() {
@Override
public String getString(String string) throws RemoteException {
return string;
}
@Override
public List<Person> getPersonList() throws RemoteException {
Person p = new Person("p1",10,1l,90);
Person p2 = new Person("p2",12,2l,92);
List<Person> list = new ArrayList<>();
list.add(p);
list.add(p2);
return list;
}
};
}
}
3.IPC传输的对象类Person.java
package demo.com.aidldemo;
import android.os.Parcel;
import android.os.Parcelable;
public class Person implements Parcelable {
private String name;
private int age;
private long workingDay;
private double money;
public Person(String name, int age, long workingDay, double money) {
this.name = name;
this.age = age;
this.workingDay = workingDay;
this.money = money;
}
protected Person(Parcel in) {
name = in.readString();
age = in.readInt();
workingDay = in.readLong();
money = in.readDouble();
}
public static final Creator<Person> CREATOR = new Creator<Person>() {
@Override
public Person createFromParcel(Parcel in) {
return new Person(in);
}
@Override
public Person[] newArray(int size) {
return new Person[size];
}
};
@Override
public int describeContents() {
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(name);
dest.writeInt(age);
dest.writeLong(workingDay);
dest.writeDouble(money);
}
@Override
public String toString() {
return "Person{" +
"name='" + name + '\'' +
", age=" + age +
", workingDay=" + workingDay +
", money=" + money +
'}';
}
}
4.清单文件配置，让服务端启动在其他进程
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="demo.com.aidldemo">
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service
android:process=":remote"
android:name=".MyService"
android:enabled="true"
android:exported="true">
<intent-filter>
<action android:name="demo.com.aidldemo.MyService" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</service>
</application>
</manifest>
5.客户端调用
package demo.com.aidldemo;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.content.ServiceConnection;
import android.os.IBinder;
import android.os.RemoteException;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
private IMyAidlInterface myAidlInterface;
TextView textView,textView2;
Button button, button2;
private ServiceConnection mServiceConnection = new ServiceConnection() {
@Override
public void onServiceConnected(ComponentName name, IBinder service) {
myAidlInterface = IMyAidlInterface.Stub.asInterface(service);
}
@Override
public void onServiceDisconnected(ComponentName name) {
}
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//使用意图对象绑定开启服务
Intent intent = new Intent();
//在5.0及以上版本必须要加上这个
intent.setPackage("demo.com.aidldemo");
intent.setAction("demo.com.aidldemo.MyService");//这个是上面service的action
bindService(intent, mServiceConnection, Context.BIND_AUTO_CREATE);
textView = findViewById(R.id.textView);
textView2 = findViewById(R.id.textView2);
button= findViewById(R.id.button);
button2= findViewById(R.id.button2);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
try {
if(myAidlInterface != null) {
textView.setText(myAidlInterface.getString("Hello AIDL"));
}
} catch (RemoteException e) {
e.printStackTrace();
}
}
});
button2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
try {
if(myAidlInterface != null) {
textView2.setText(myAidlInterface.getPersonList().toString());
}
} catch (RemoteException e) {
e.printStackTrace();
}
}
});
}
@Override
protected void onDestroy() {
super.onDestroy();
if (mServiceConnection != null){
unbindService(mServiceConnection);
}
}
}
6.布局文件
