使用AIDL调用服务中的方法

AIDL:android interface define language(接口定义语言)

作用：方便远程调用其他服务中的方法

注意：安卓四大组件都要在清单文件注册

aidl创建图：

interface InterfaceAidl {
   void interfacePay();
}

public class MyService extends Service {

    class MyBinder extends InterfaceAidl.Stub {
        @Override
        public void interfacePay() throws RemoteException {
            pay();
        }
    }

    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        MyBinder binder = new MyBinder();
        return binder;
    }

    private void pay() {
        Log.i("service","支付成功");
    }
}

public class MainActivity extends AppCompatActivity {
    private Intent intent;
    private MyServiceConnection myServiceConnection;
    private InterfaceAidl interfaceAidl;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        intent = new Intent(this,MyService.class);
        myServiceConnection = new MyServiceConnection();
    }

    public void bind(View view){
        bindService(intent, myServiceConnection, BIND_AUTO_CREATE);
    }

    public void pay(View view){
        try {
            interfaceAidl.interfacePay();
        } catch (RemoteException e) {
            e.printStackTrace();
        }
    }

    class MyServiceConnection implements ServiceConnection{
        @Override
        public void onServiceConnected(ComponentName name, IBinder service) {
            interfaceAidl = InterfaceAidl.Stub.asInterface(service);
        }

        @Override
        public void onServiceDisconnected(ComponentName name) {

        }
    }

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

远程调用服务

interface InterfaceAidl {
   void interfacePay();
}

<service android:name=".MyService">
            <intent-filter>
                <action android:name="aidl_interface.pay"></action>
            </intent-filter>
        </service>

public class MainActivity extends AppCompatActivity {

    private Intent intent;
    private InterfaceAidl interfaceAidl;
    private MyServiceConnection myServiceConnection;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        intent = new Intent();
        myServiceConnection = new MyServiceConnection();
        intent.setAction("aidl_interface.pay");
        intent.setPackage("com.example.administrator.aidlservice");
    }

    public void bind(View view){
        bindService(intent,myServiceConnection,BIND_AUTO_CREATE);
    }

    public void pay(View view){
        try {
            interfaceAidl.interfacePay();
        } catch (RemoteException e) {
            e.printStackTrace();
        }
    }

    class MyServiceConnection implements ServiceConnection{

        @Override
        public void onServiceConnected(ComponentName name, IBinder service) {
            interfaceAidl  = InterfaceAidl.Stub.asInterface(service);
        }

        @Override
        public void onServiceDisconnected(ComponentName name) {

        }
    }

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