第一步:创建一个远程服务,如我的RemoteService.java  (记得在文件清单中声明service)

package com.itheima.remoteservice;

import android.app.Service;
import android.content.Intent;
import android.os.Binder;
import android.os.IBinder;

public class RemoteService extends Service {

	@Override
	public IBinder onBind(Intent intent) {
		// TODO Auto-generated method stub
		return null;
	}

	public void banzheng(){
		System.out.println("李局帮你来办证");
	}
}



其中public void banzheng()是我将要对其进行访问的方法,那么接下来如何访问呢?


第二步:在服务里边创建一个内部类,让其继承Binder,这样我们就可以new一个内部类对象,让其通过public IBinder onBind()方法将其返回给调用服务者;

与此同时,在内部类中,构造我们自己的方法,然后在方法内调用服务中的方法public void banzheng(),改造之后的结果如下图所示:

package com.itheima.remoteservice;

import android.app.Service;
import android.content.Intent;
import android.os.Binder;
import android.os.IBinder;

public class RemoteService extends Service {

	@Override
	public IBinder onBind(Intent intent) {
		// TODO Auto-generated method stub
		return new furong();
	}
	
	class furong extends Binder{

		public void qianXian() {
			// TODO Auto-generated method stub
			banzheng();
		}
	}
	
	public void banzheng(){
		System.out.println("李局帮你来办证");
	}
}




第三步:把内部类里边的方法抽象出来

我们之后,若我们直接这样把中间对象IBinder传递过去,尽管是能传递过去,

但是在服务调用者那边,还是没法把其强转过来,因为创建服务和启动服务是在两个应用里边;

所以仍需要对其进行进一步改造,也就是:创建一个接口,把内部类里边的方法抽象出来放在我们新定义的接口里边,

然后让内部类实现这个接口;如我的接口及服务中的内部类如下:

服务中的内部类:

package com.itheima.remoteservice;

import android.app.Service;
import android.content.Intent;
import android.os.Binder;
import android.os.IBinder;

public class RemoteService extends Service {

	@Override
	public IBinder onBind(Intent intent) {
		// TODO Auto-generated method stub
		return new furong();
	}
	
	class furong extends Binder implements PublicBusiness{

		public void qianXian() {
			// TODO Auto-generated method stub
			banzheng();
		}
	}
	
	public void banzheng(){
		System.out.println("李局帮你来办证");
	}
}




另外新定义一个接口:

package com.itheima.remoteservice;

public interface PublicBusiness {
	void qianXian();
}




第四步:找到接口文件的目录,然后将接口的后缀名修改为 .aidl   然后刷新工程,不然看不到修改之后的效果

修改之前的效果:

hive远程模式可以连接idea吗 使用aidl完成远程service方法调用_android

修改之后的效果:

hive远程模式可以连接idea吗 使用aidl完成远程service方法调用_android_02

修改之后,我们看到,很多地方都出现了错误,别急,我们按照错误提示慢慢修改:

先将接口的权限修饰符public去掉,呈现的效果如下:

package com.itheima.remoteservice;

interface PublicBusiness {
	void qianXian();
}



与此同时,我们看到,左侧工程的gen包下自动生成了PublicBusiness.java

hive远程模式可以连接idea吗 使用aidl完成远程service方法调用_android_03

进入gen包下的PublicBusiness.java的类中,我们可以看到如下一行:

hive远程模式可以连接idea吗 使用aidl完成远程service方法调用_内部类_04


第五步:修改RemoteService.java文件,这个文件就是我们的服务

通过第四步,我们得知,Stub既继承了Binder又实现了PublicBusiness接口,这样很容易,让我们想到,我们的内部类的实现

class furong extends Binder implements PublicBusiness

因此,我们让furong内部类直接去继承Stub,其实际效果如下:

package com.itheima.remoteservice;

import com.itheima.remoteservice.PublicBusiness.Stub;

import android.app.Service;
import android.content.Intent;
import android.os.Binder;
import android.os.IBinder;

public class RemoteService extends Service {

	@Override
	public IBinder onBind(Intent intent) {
		// TODO Auto-generated method stub
		return new furong();
	}
	
	class furong extends Stub{

		public void qianXian() {
			// TODO Auto-generated method stub
			banzheng();
		}
	}
	
	public void banzheng(){
		System.out.println("李局帮你来办证");
	}
}



hive远程模式可以连接idea吗 使用aidl完成远程service方法调用_android_05



第六步:创建启动服务的调用者

我们知道,我们的服务虽然构建好,但是,需要有人来启动,所以,我们这步的任务就是创建一个服务调用者,如:

package com.itheima.runremote;


import android.os.Bundle;
import android.os.IBinder;
import android.os.RemoteException;
import android.app.Activity;
import android.content.ComponentName;
import android.content.Intent;
import android.content.ServiceConnection;
import android.view.Menu;
import android.view.View;

public class MainActivity extends Activity {

	private MyserviceConn conn;

	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		conn = new MyserviceConn();
	}

	public void click3(View v){
		//绑定远程服务
		Intent intent = new Intent();
		intent.setAction("com.itheima.remote");
		bindService(intent, conn, BIND_AUTO_CREATE);
	}

	public void click4(View v){
		//解绑远程服务
		unbindService(conn);
	}
	class MyserviceConn implements ServiceConnection{

		@Override
		public void onServiceConnected(ComponentName name, IBinder service) {
			
			
		}

		@Override
		public void onServiceDisconnected(ComponentName name) {
			// TODO Auto-generated method stub
			
		}
		
	}
	
}



注:在这里,我是通过点击按钮来让触发器绑定和解绑的;


第七步:访问服务里边的方法

先在调用服务的工程里边创建一个工程,需同服务里边的包名一样

然后将RemoteService.aidl文件拷贝到创建的这个包名下,如:

hive远程模式可以连接idea吗 使用aidl完成远程service方法调用_android_06

最后就是在public void onServiceConnected()方法里,把Ibinder中间人对象强转成publicbusiness

然后调用publicbusiness里边的方法qianXian(),这样就达到了访问服务里边banzheng()方法的目的;

启动远程服务的示例如下:

package com.itheima.runremote;

import com.itheima.remoteservice.PublicBusiness;
import com.itheima.remoteservice.PublicBusiness.Stub;

import android.os.Bundle;
import android.os.IBinder;
import android.os.RemoteException;
import android.app.Activity;
import android.content.ComponentName;
import android.content.Intent;
import android.content.ServiceConnection;
import android.view.Menu;
import android.view.View;

public class MainActivity extends Activity {

	private MyserviceConn conn;

	PublicBusiness pb;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		conn = new MyserviceConn();
	}

	public void click(View v){
		//启动远程服务
		Intent intent = new Intent();
		intent.setAction("com.itheima.remote");
		startService(intent);
	}
	public void click2(View v){
		//停止远程服务
		Intent intent = new Intent();
		intent.setAction("com.itheima.remote");
		stopService(intent);
	}
	
	public void click3(View v){
		Intent intent = new Intent();
		intent.setAction("com.itheima.remote");
		bindService(intent, conn, BIND_AUTO_CREATE);
	}

	public void click4(View v){
		unbindService(conn);
	}
	class MyserviceConn implements ServiceConnection{

		@Override
		public void onServiceConnected(ComponentName name, IBinder service) {
			//把Ibinder中间人对象强转成publicbusiness
			pb = Stub.asInterface(service);
		}

		@Override
		public void onServiceDisconnected(ComponentName name) {
			// TODO Auto-generated method stub
			
		}
		
	}
	
	public void click5(View v){
		try {
			pb.qianXian();
		} catch (RemoteException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
}

		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.main, menu);
		return true;
	}
