RPC的简单实例
先新建一个aidl文件
IPerson.aidl
package comhoperun.aidl;
interface IPerson{
void setName(String name);
void setAge(int age);
String display();
}
再新建对应的java文件
IPersonImpl.java
package com.hoprun.activity;
import android.os.IBinder;
import android.os.RemoteException;
import comhoperun.aidl.IPerson;
public class IPersonImpl extends IPerson.Stub {
String name;
int age;
@Override
public IBinder asBinder() {
return null;
}
@Override
public void setName(String name) throws RemoteException {
this.name = name;
}
@Override
public void setAge(int age) throws RemoteException {
this.age = age;
}
@Override
public String display() throws RemoteException {
// TODO Auto-generated method stub
return "name : " + name + " age : " + age;
}
}
RpcService.java
package com.hoprun.activity;
import comhoperun.aidl.IPerson.Stub;
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
public class RpcService extends Service {
//把实现类赋值给Stup,接口的静态内部类
Stub person = new IPersonImpl();
@Override
public IBinder onBind(Intent intent) {
//RPC:远程进程访问,在IPerson类中有定义
return person;
}
}
RPCServiceActivity.java
package com.hoprun.activity;
import android.app.Activity;
import android.app.Service;
import android.content.ComponentName;
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 comhoperun.aidl.IPerson;
public class RPCServiceActivity extends Activity {
/** Called when the activity is first created. */
public static final String SERVICE_STR = "com.hoperun.service";
Button button_service;
IPerson iperson;
//绑定service时,调用的ServiceConnection
ServiceConnection conn = new ServiceConnection(){
@Override
public void onServiceConnected(ComponentName name, IBinder service) {
//获得接口IPerson
iperson = IPerson.Stub.asInterface(service);
if(iperson != null){
try {
//RPC方法调用
iperson.setName("zhangsan");
iperson.setAge(23);
String msg = iperson.display();
Toast.makeText(RPCServiceActivity.this, msg, Toast.LENGTH_SHORT).show();
} catch (RemoteException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
@Override
public void onServiceDisconnected(ComponentName name) {
// TODO Auto-generated method stub
}
};
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//定义按钮
button_service = (Button) findViewById(R.id.button_service);
button_service.setText("aidl绑定Service");
//绑定监听器
button_service.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent();
intent.setAction(SERVICE_STR);
//绑定service
bindService(intent, conn, Service.BIND_AUTO_CREATE);
}
});
}
}
