Android 之简单 AIDL 客户端和服务端 附源码

AIDL 的全称是 Android Interface Definition Language(即 Android 接口定义语言)

在同一个app中

/ * * * * 首先在main 文件下定义 aidl 文件

// IMyAidlInterface.aidl
package com.test.service;

// Declare any non-default types here with import statements

interface IMyAidlInterface {
    /**
     * Demonstrates some basic types that you can use as parameters
     * and return values in AIDL.
     */
    void basicTypes(int anInt, long aLong, boolean aBoolean, float aFloat,
            double aDouble, String aString);
            int add(int a,int b);
            int minus(int a,int b );
}

/ * * * * 在service 中，先运行一下 等待生成 则可以调用接口了
点击 Build -> Make Project，然后等待构建完成。

public class TestService extends Service {
    private static final String TAG = TestService.class.getSimpleName();

    @Override
    public IBinder onBind(Intent intent) {
        return mBinder;
    }


    private final IMyAidlInterface.Stub mBinder = new IMyAidlInterface.Stub() {
        @Override
        public void basicTypes(int anInt, long aLong, boolean aBoolean, float aFloat, double aDouble, String aString) throws RemoteException {

        }

        @Override
        public int add(int a, int b) throws RemoteException {
            return a+b;
        }

        @Override
        public int minus(int a, int b) throws RemoteException {
            return a-b;
        }
    };

}

/ * * * * 在客户端调用

public class MainActivity extends Activity {
    public static final String TAG = MainActivity.class.getSimpleName();
    public static final int MEG_SUM = 0x1100;
    private IMyAidlInterface.Stub mBinder;
   private Handler mHandler = new Handler(){

       @Override
       public void handleMessage(Message msg) {
           super.handleMessage(msg);
           switch (msg.what) {
               case MEG_SUM:
                   Toast.makeText(MainActivity.this, "接收到service消息==>" + msg.arg1, Toast.LENGTH_SHORT).show();
           }

       }
   };

    ServiceConnection connection = new ServiceConnection() {
        @Override
        public void onServiceConnected(ComponentName name, IBinder service) {
            mBinder = (IMyAidlInterface.Stub) service;

            try {
                msg = mBinder.add(3, 3);
            } catch (RemoteException e) {
                e.printStackTrace();
            }
            Toast.makeText(MainActivity.this, "Activity发送消息", Toast.LENGTH_SHORT).show();

            Message message = Message.obtain();
            message.what = MEG_SUM;
            message.arg1 = msg;
            mHandler.sendMessage(message);
        }
        @Override
        public void onServiceDisconnected(ComponentName name) {
        }
    };
    private int msg;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Intent intent = new Intent(this, TestService.class);
        bindService(intent, connection, Context.BIND_AUTO_CREATE);


    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        unbindService(connection);
    }

}

在不同一个app中

/ * * * * * * Client * * * * * * *Service
相同的位置相同的地方 用相同的所有

/ * * * * * Service

public class TestService extends Service {
    private static final String TAG = TestService.class.getSimpleName();
    private IMyAIDL iMyAIDL;

    @Override
    public IBinder onBind(Intent intent) {
        return iMyAIDL;
    }

    @Override
    public void onCreate() {
        super.onCreate();
        iMyAIDL = new IMyAIDL();
    }



  public  class  IMyAIDL  extends IMyAidlInterface.Stub{

      @Override
      public void basicTypes(int anInt, long aLong, boolean aBoolean, float aFloat, double aDouble, String aString) throws RemoteException {

      }

      @Override
      public int add(int a, int b) throws RemoteException {
          return a+b;
      }

      @Override
      public int minus(int a, int b) throws RemoteException {
          return a-b;
      }
  }

}
