android 简单的aidl

 1.首先在src目录下建立一个file,命名为IPerson.aidl

package com.example.aidldemo;interface IPerson {    void setAge(int age);    void setName(String name);    String display();}

2.接着要实现这个aidl里面的方法

package com.example.aidldemo;import android.os.RemoteException;public class IPersonImpl extends IPerson.Stub{    //声明两个变量    private int age;    private String name;    @Override    public void setAge(int age) throws RemoteException {        this.age=age;    }    @Override    public void setName(String name) throws RemoteException {        this.name=name;    }    @Override    public String display() throws RemoteException {        return "name="+name+";age="+age;    }}

3.建立一个service

package com.example.aidldemo;import com.example.aidldemo.IPerson.Stub;import android.app.Service;import android.content.Intent;import android.os.IBinder;public class MyRemoteService extends Service {    private Stub iPerson=new IPersonImpl();    @Override    public IBinder onBind(Intent intent) {        // TODO Auto-generated method stub        return iPerson;    }}

4.在activity中启动服务

package com.example.aidldemo;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.view.Menu;public class MainActivity extends Activity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        Intent intent = new Intent();        // 设置Intent Action 属性        intent.setAction("com.example.aidldemo.action.MY_REMOTE_SERVICE");        // 绑定服务        startService(intent);    }    @Override    public boolean onCreateOptionsMenu(Menu menu) {        // Inflate the menu; this adds items to the action bar if it is present.        getMenuInflater().inflate(R.menu.activity_main, menu);        return true;    }}

5.新建一个项目,把上一个项目中的aidl拷贝到项目中
在activity中实现如下:

 

package com.example.aidlclient;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.view.Menu;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.Toast;import com.example.aidldemo.IPerson;public class MainActivity extends Activity {    private IPerson iPerson;    private Button btn;    // 实例化ServiceConnection        private ServiceConnection conn = new ServiceConnection() {            @Override            synchronized public void onServiceConnected(ComponentName name, IBinder service) {                // 获得IPerson接口                iPerson = IPerson.Stub.asInterface(service);                System.out.println("iperson----------:"+iPerson);            }            @Override            public void onServiceDisconnected(ComponentName name) {                iPerson=null;            }        };        @Override        public void onCreate(Bundle savedInstanceState) {            super.onCreate(savedInstanceState);            // 设置当前视图布局            setContentView(R.layout.activity_main);            // 实例化Button            btn = (Button) findViewById(R.id.button1);            //为Button添加单击事件监听器                        // 实例化Intent            Intent intent = new Intent("com.example.aidldemo.action.MY_REMOTE_SERVICE");            // 设置Intent Action 属性            bindService(intent, conn, Service.BIND_AUTO_CREATE);                        btn.setOnClickListener(new OnClickListener() {                @Override                public void onClick(View v) {                                                            try{                        iPerson.setAge(20);                        iPerson.setName("南瓜饼");                        String msg = iPerson.display();                        // 显示方法调用返回值                        Toast.makeText(MainActivity.this, msg, Toast.LENGTH_LONG).show();                    }catch (Exception e) {                        e.printStackTrace();                    }                }            });                    }                @Override        protected void onDestroy()        {            // TODO Auto-generated method stub            unbindService(conn);            super.onDestroy();        }    @Override    public boolean onCreateOptionsMenu(Menu menu) {        // Inflate the menu; this adds items to the action bar if it is present.        getMenuInflater().inflate(R.menu.activity_main, menu);        return true;    }}
