Android BinderService 过程

步骤：建立服务器端服务，暴露接口

1.BinderService

13 import android.os.Binder;
14 import android.os.IBinder;
15
16 public class BinderService extends Service {

35
36         return mBinder;
37
38     }

41 }

2.客户端

 1 package cn.boxai.binderservice;

 3 import cn.boxai.binderservice.BinderService.MyBinder;
 4 import android.os.Bundle;
 5 import android.os.IBinder;
 6 import android.app.Activity;
 7 import android.content.ComponentName;
 8 import android.content.Intent;
 9 import android.content.ServiceConnection;
10 import android.util.Log;
11 import android.view.Menu;
12 import android.view.View;
13 import android.view.View.OnClickListener;
14 import android.widget.Button;
15 import android.widget.Toast;
16
17 public class BinderServiceActivity extends Activity {
18  Button mBinderServiceButton;
19     @Override
20     protected void onCreate(Bundle savedInstanceState) {
21         super.onCreate(savedInstanceState);
22         setContentView(R.layout.activity_main);
23         mBinderServiceButton=(Button) findViewById(R.id.btn_BinderService);
24         mBinderServiceButton.setOnClickListener(new  OnClickListener()
25         {
26
27             @Override
28             public void onClick(View v)
29             {
30             // step 5:call interface from server
31             //bindService     parameter=>_intent
32                 Intent _intent=new  Intent(BinderServiceActivity.this,BinderService.class);
33                 bindService(_intent, conn, BinderService.BIND_AUTO_CREATE);
34             }
35         });
36
37     }
38     //step 6:bindService     parameter=>conn
39 private ServiceConnection conn=new ServiceConnection()
40 {
41
42     @Override
43     public void onServiceDisconnected(ComponentName name) {
44
45         // TODO Auto-generated method stub
46
47     }
48
49     @Override
50     public void onServiceConnected(ComponentName name, IBinder service) {
51
52         //step 7:receive server method
53         String bindername=((MyBinder)service).helloWorld("LD");
54         Toast.makeText(BinderServiceActivity.this, bindername, 3000).show();
55         Log.i("BinderService", "BinderService==>"+bindername);

　　　　　　((MyBinder)service).getService().helloservice();//绑定其他服务
56     }
57 };
58
59
60
61
62 }

取消绑定

客户端

   Button mUnBinderServiceButton;

    //取消绑定
        mUnBinderServiceButton=(Button) findViewById(R.id.btn_UnBinderService);
        mUnBinderServiceButton.setOnClickListener(new  OnClickListener()
        {

            @Override
            public void onClick(View v)
            {
             unbindService(conn);

            }
        });

服务端端

    @Override
    public boolean onUnbind(Intent intent) {

        // TODO Auto-generated method stub
        return super.onUnbind(intent);

    }
